Installation Guidelines

 

Installation Guidelines for Patterned and Non-Patterned Carpet

Before you start the installation process, please read this bulletin and any other applicable literature pertaining to the installation of Signature carpet. Due to the pattern complexities in ColorPoint, ColorTech and CYP (Tapistron) products, a higher level of installation expertise is required.

Warranties from Signature specifically exclude claims involving carpet which has been cut and installed with visible manufacturing defects. Please inspect your carpet before the installation process. Inspect for concealed damage, manufacturing defects and shipping errors, for example wrong color, style, pattern, size, etc. If material has been cut, fitted or installed then no adjustments or claims will be considered.

Tools and Materials

Install carpet using tools and materials referenced in this guideline. Proper tools and quality materials are essential for skilled and proficient carpet installation.

Storage

Store carpet and related materials in a climate-controlled, dry space. To prevent any consequential damage, Signature recommends that the carpet remain in its protective plastic wrapping until needed. To prevent excessive pile crush, or distortion, store the carpet on single racks. Do not stack rolls for extended periods.

Handling

Transport carpet in a manner that prevents damage and/or distortion. Bending or folding individual carpet rolls or cuts from rolls is not recommended. When bending or folding is absolutely unavoidable for delivery purposes, the carpet is required to be unrolled and allowed to lie flat immediately upon arrival at the installation site.

Planning

All facets of the installation need to be coordinated. A scaled drawing of the area to be installed is required to determine type of carpet, carpet quantities, quantity per dye lot, installation method, cushions, adhesives, transition molding, wall base types and other accessories, and to identify the proper location of seams. On new construction, provide architectural drawing that define the entire installation area with space names and/or numbers and a finish schedule of flooring styles, patterns, colors and installation methods. On existing structures, provide new measurements and shop drawings. Consideration should be given to carpet and adhesive conditioning, material delivering considerations and other trades’ schedules.

9

Note: Should other trades perform work in areas where Signature carpet has been installed, the installer and/or general contractor assumes total liability for damage and/or deterioration, including wear, compaction, soiling, staining, abrasion and stretching. Failure to provide adequate protection until occupancy may void all Signature warranties.

Planning for Seams

A comprehensive seaming diagram must be submitted and approved by the purchasing parties prior to installation.

9

Note: Keep seams to a minimum. Seams should run lengthwise in major areas, parallel to traffic paths, into natural and artificial light sources, and be avoided at major pivot points where they may intersect perpendicular to doorways and entrances. Allow trimming approximately 1″ to 1.5″ of actual face material for seams. Patterns may require additional trimming.

Transitions to Other Surfaces

Where carpet transitions to other floor coverings, the carpet edges are required to be protected or covered with appropriate transition moldings. The edge of the hard surface flooring should not exceed a maximum of 1/16″ higher than the total carpet thickness where no transition molding exists. Where no transition molding is needed or used, apply a minimum of 1/8″ bead of seam sealer to the edge of the carpet along the entire transition. Cove base or base-with-toe is highly recommended for use in direct glue or double glue carpet installations.

Carpet Over Expansion Joints

Do not install carpet over expansion joints. Expansion joints allow separate substrate surfaces to expand and contract independently. In addition, do not install on any area of a floor that does not provide a stable and mechanically sound surface. This does not include cut or saw joints within a section of the floor. Non-stable and/or unsound substrate joint conditions are required to be address in strict accordance with the appropriate architectural drawing. If no expansion joint device is specified on the drawing, the building owner, owner’s representative, or other responsible party is required to be made aware that failure to address expansion joints will potentially result in installation failure, damage to the carpet and/or safety concerns and will void the Signature carpet’s warranty.

Pile Direction

Where two or more pieces of the same broadloom carpet are adjacent, the pile direction is required to be the same unless otherwise specified by the manufacturer. Uniform pile direction is not required with dissimilar carpet.

9

Note: Ideally, install carpet with the pile lay towards the entrance; but other factors, such as pattern, aesthetics and economic use of material may be considered.

 

Site Conditions – All Installation

Substrate Conditions

The owner or general contractor is responsible for providing an acceptable substrate for the specified installation.

9

Note: Installing carpet prematurely before other trades have completed their work can, and most likely will, result in problems with: overall appearance, visible damage, soiling, adhesive failure, delamination and dimensional stability. These conditions may not be immediately evident.

Ambient Temperature and Humidity

The installation is not to begin until the HVAC system is operational and the following conditions are maintained for at least 48 hours (2 days) before, during and 72 hours (3 days) after completion. The carpet needs to be installed when the indoor temperature is between 65-95ºF (18-35ºC) with a maximum relative humidity of 65%. The substrate surface temperature should not be less than 65ºF (18ºC) at the time of installation. Do not allow the temperature of indoor carpeted areas to fall below 50ºF (10ºC), regardless of the age of the installation. If these conditions are not attainable, please contact Signature for applications to warranty.

Floor Preparation

Carpet is required to be installed over properly prepared substrates that are suitable for the specific product and installation method selected. All cracks, holes and flooring irregularities are required to be properly repaired to ensure a smooth, finished appearance, prevent accelerated wear and telegraphing substrate irregularities. Substrates are required to be structurally sound and free of foreign substances that will compromise the carpet and/or its installation. Patching compounds are are required to be suitable for the use application.

9

Note: Patched area may be porous and highly alkaline, which will prevent adequate adhesive bond. For best results, prime patched areas. Consult the patch manufacturer for primer recommendations and compatibility with adhesives.

Concrete Flooring

Concrete must be cured, clean and dry before carpet installation. Cracks, chips and saw cuts must be properly patched and/or treated. Concrete is available in two (2) basic forms: lightweight and normal weight. This difference is based on the type of aggregate used in the mix. Lightweight concrete is most commonly, but not exclusively, used on upper floors. Various flooring screeds and topcoats that are available — typically gypsum-based –are not lightweight concrete.

s

Caution: Any concrete floor, even when adequately cured and dry, can allow moisture vapor to pass through to its surface. Depending upon the type of carpet and method of installation, the moisture emission rate influences the long-term success of an installation. The use of a properly installed, uncompromised, approved moisture membrane is essential in preventing moisture migration into and through a concrete slab.

Testing Concrete Substrates

Before direct glue-down, double-glue down and some stretch-in (non-porous cushion and/or carpet) installations, the owner or general contractor, or their designated testing agent, is required to submit to the flooring contractor a written report on the moisture and alkalinity conditions of the concrete substrates.

Concrete Moisture Content

New concrete subfloors must be cured. Slab temperature must always be above 55ºF (13ºC) before and during testing. All concrete subfloors, regardless of age, must be tested for excessive moisture content within the slab. There are two approved types of moisture testing used for testing moisture in the concrete slab. Moisture Vapor Emission Rate testing (MVER Calcium Chloride) tests vapor emissions of the concrete slab in a 24 hour period and the Relative Humidity (RH Probes) tests the moisture inside the concrete slab. All testing must be conducted utilizing the latest ASTM standards. Signature has identified and determined that the RH text method to be superior of the two methods.

Moisture Vapor Emission Testing — MVER should not exceed 5lb. per 1,000 square feet in 24 hours. This test must be conducted utilizing the latest edition of ASTM F-1869.

Relative Humidity Testing — RH testing should not exceed 75% relative humidity at any time. This test must be conducted utilizing the latest edition of ASTM F-2170.

Concrete Alkalinity Content

Test all new or existing older concrete for excessive alkalinity. Perform this test in accordance with the latest edition of ASTM F-710. If pH is equal to or exceeds 9 on the scale, notify general contractor for corrective measures. Do not install carpet over concrete that has alkalinity content equal to or exceeds 9 on the scale.

9

Note: It is recommended that qualified independent third-party testing agencies be used for determining moisture and alkalinity conditions of a concrete slab. Testing by an independent third-party specialist to determine installation suitability is a prudent and necessary safeguard for general contractors, owners, architects, flooring product providers and installation contractors to reduce the risk of concrete slab-related flooring problems. As a minimum, testing agencies or individuals are required to demonstrate verifiable experience in concrete testing and/or be certified by a recognized organization.

Wood Flooring

Wood substrates are required to be structurally sound, flat, dry and securely anchored. Substrates, such as plywood, hardwood, particleboard, oriented strand board, or other materials, are required to be flooring grade (APA-approved) and installed according to manufacturer specifications. Irregularities, imperfections and joints are required to be properly patched and prepared. It is required that all protrusions be properly prepared.

9

Note: Particleboard is not a recommended underlayment. Strip or plank wood flooring and OSB sub-floors must be covered with an approved underlayment (minimum thickness of 1/4″).

CAUTION: Some sheet vinyl, resilient tile and cut-back asphalt-based adhesive may contain asbestos and/or crystalline silica. Inhaling dusts from these materials creates a cancer and respiratory system hazard. Lacking documented evidence to the contrary, e.g., current testing, assume that these materials contain asbestos and treat them in the manner prescribed for removing floors containing asbestos. Recommended work practices prohibit sanding, dry scraping, bead-blasting or mechanically pulverizing resilient flooring, backing or lining felt. Do not use powered devices that create asbestos dust when removing “cut-back” or asphalt-based adhesives. It is required that removal procedures comply with federal, state and local government agency regulations covering the removal and disposal of asbestos-containing materials (ACM).

 

Carpet Preparation

Relaxing and Conditioning Carpet

To minimize wrinkling and buckling and also to facilitate installation, it is highly recommended that carpet by unrolled and allowed to relax in the installation area. This time period should be up to 72 hours (3 days), but cannot be less than 24 hours at a temperature between 65-95ºF (18-35ºC). Protect relaxing carpet adequately from soil, dust, moisture and other contaminants. Sundry items, such as adhesives, should be conditioned as well. If these conditions are not attainable, contact Signature for applications to warranty.

9

Note: The allocation of time for the relaxation period should be included in the planning of the installation job by all interested parties.

Patterned Carpet

The best pattern match will come from cuts taken from the same roll. Plan ahead by verifying lengths. Always allow extra carpet to compensate for pattern matching. Pattern carpets require the use of a knee kicker, mini-stretcher (seams grabs), deadman and power stretcher to assure the best pattern alignment. Cut and layout carpet based on pattern variances to best minimize pattern match efforts. Pre-stretch carpet prior to installing for pattern elongation and always stretch short side to match long side of pattern. Starting point should be dictated by type of pattern distortion. An acceptable pattern match should be obtainable.

Patterned Match Tolerances

All pattern carpet is subject to certain industry tolerances. At Signature, our tolerances are more stringent than most industry standards. Please stop installation and contact Signature if the below tolerances have been exceeded. Our tolerances are as follows:

  1. If bowing or skewing is greater than 1 1/2 inch in a 12 foot width
  2. If bowing or skewing is greater than 1 1/2 inch in a 20 foot length
  3. If pattern elongation is more than an average of 2.0%

We have established our tolerances so that a match should be achievable by stretching the short side to meet the long side. WE DO NOT GUARANTEE PATTERN REPEAT MATCH.

Trim Pattern

It is extremely fundamental to know that the pattern is actually tufted into the carpet, not printed on it. Because of this tufted characteristic, the pattern and the rows must line up. You must cut the center row of a diamond pattern and follow that row. Regardless of how far you travel, that row will fall exactly in the same place in the pattern every time it repeats.

Because of the tufted pattern characteristics, it is helpful to use a blunt object (screwdriver, awl, etc.) to open up or follow the row prior to using a row cutter, thus cutting the pattern in exactly the same place each time.

9

Note: If the pattern is not cut on the row, it will not match. Chalk line, straight edge, or freehand cuts are not acceptable methods and will not achieve a match.

Match Pattern (Correction for Pattern Elongation)

Once the patterned carpet has been trimmed in the proper fashion:

  1. An easy way to determine which cuts will match best is to count off 30 patterns and compare the measurements to determine the sequence.
  2. Dry fit all pieces prior to beginning the installation.
  3. Cut at least 24 hours in advance, if possible. This allows the carpet to relax.
  4. If pattern is only slightly off, tightly rolling the short side drops face out. Leaving it rolled for 24 hours can help.
  5. Match all patterns in center of seam and work towards the ends.
  6. If you are mixing dye lots, do not expect color or pattern to exactly match.

Determine the short patterned and long patterned sides. Since there is no dependable way to shrink a synthetic tufted carpet, we must us the opposite process of stretching. We are simply going to stretch the short pattern side out to meet the long pattern side.

Seaming

Each seaming method requires the expertise of qualified carpet installer journeymen and the company contracted to do this kind of work should be pre-qualified with references. To make a good seam, it is necessary to trim selvages (not to include the face yarn of the pattern) using a “loop pile cutter” or top pile cutter. Use an awl, row runner, screwdriver, pen or comb to run the row where the seam will be and then cut. As soon as you apply the adhesive, press the latex into the base of the carpet pile sealing the edge, being careful not to disturb the yarn.

9

Note: The selvage is the extended edge of the backing and it may also include off-colored yarn or small overmatch that extends past the face yarn of the pattern on each side of the roll width. It is mandatory to trim all the selvage, waste yarn, or overmatch off the carpet. All cuts that are made in preparation for seaming must have a “bead” of latex adhesive applied to the backing edge, being careful not to get any adhesive on the face yarn.

Hot Melt Tape

When hot melt tape is used. the carpet must have a 100% synthetic back and a 3″ to 6″ wide seaming tape must be used. In a carpet installation, even when the seams are properly constructed, most length seam failure is due to the tape splitting; not the releasing of the adhesive from the carpet back. Test for adhesive “bond” before constructing the seams. Use a heat shield on your seaming iron at all times. You may want to test a piece of scrap carpet for heat resistance to make sure you will not distort the face fibers with too much heat in this process.

Abut the two prepared runs, matching the pattern for the length of the seam. You may have to stretch both widths of the carpet runs at the seam and “stay nail” each piece before hot melting the seam with the tape. Roll out and center the seaming tape under the two pieces to be seamed. Apply the preheated iron to the tape at the starting point and allow time to adequately melt the adhesive on the tape. Whenever possible, start at the end of a seam, allowing the iron movement to go all in the same direction. If the seam is a long one, you may find it necessary to have your starting point at the center of the seam and continue to the end. Return to the middle and proceed to the other end to finish.

Move your iron at an even speed, approximately 3′ per minute, all the while pressing the carpet into the adhesive behind the iron with your hand or a seam roller (smooth type, rather than spiked roller). Slide a flat, heavy object along the seam to keep the carpet flat as the tape cools. Always allow sufficient cooling time before stretching.

To prevent fraying and raveling at the seams, a 1/8″ (3.2 mm) continuous bead of seam adhesive should be applied to the base of the first edge where the face yarn enters the backing.

9

Note: Hot melt tap does reduce the amount of stretch capabilities at the seams. If prior stretching is not performed before the tape is applied, additional stretch in the middle of the carpet will cause a bowing effect across the pattern.

 

Glue Down Installations

BioCel™ Laminate Plus, BioCel™ Cushion, EnviroCel™ Laminate Plus, EnviroCel™ Cushion Plus and ActionBac®

  1. Glue long pattern drop in place approximately 4′-6′ wide and full length using approved adhesive.
  2. Starting from center of seam (and start with center panel if more than two (2) panels are involved), glue as far toward each end as the pattern matches and 4′-6′ wide on the short pattern drop.
  3. Seal all seams with good quality seam sealer.
  4. Place carpet in adhesive making seam only as far as match will allow.
  5. Roll with lino roller and allow setting 15-30 minutes. Stay taking may also be helpful.
  6. Roll the side with short pattern up from the ends toward center until you come back to the glued areas.
  7. Glue 8′-10′ length by 4′-6′ width (or as much as your comfort factor).
  8. Unroll carpet into adhesive. As long as adhesive is wet and slippery but not tacky.
  9. Using power stretcher (not kicker), stretch pattern into register and stay-tack (a power stretcher and deadman works best).
  10. Repeat steps 6-9 until seam is complete. Leave stay nails in place until glue sets.
  11. Use this same procedure on each of the other seams.
  12. The best way to determine pattern match is to stand back and sight down the diagonals formed by pattern.
9

Note: Special techniques are not required for all glue down installations. Carpets with polyurethane carpet backings are installed by conventional commercial broadloom techniques and require no special tools or materials. (BioCel and EnviroCel polyurethane carpet backing have a non-woven outer surface). Remember, you can only stretch the short side. Lay out all work so that this can be accomplished. Never glue the short side first. Use of a power stretcher is basic to the installation of all carpet made with ActionBac. A knee kicker cannot obtain and hold the necessary amounts of stretch. Failure to use a power stretcher is the major cause of having to re-stretch.

BioCel, EnviroCel and ActionBac backings are compatible with standard premium multi-purpose carpet adhesives and seam adhesives. We recommend Signature 2800 adhesive and Signature 1801 seam sealer which are both CRI Green Label Plus™ Certified.

Recommended Trowel Size — ActionBac, Unitary ActionBac use a 1/8″x1/8″x1/16″ U-notch trowel. BioCel and EnviroCel use 3/32″x3/32″x3/32″ V-notch trowel. Always maintain consistent notch size throughout installation.

Before placing the carpet, the adhesive must be allowed an open or dwell time appropriate for the carpet backing, installation site and sub-floor conditions. It is extremely important to maintain recommended notch depth, width and spacing. The proper notch depth is one which will produce adhesive ridges that affect a 100% transfer to both the substrate and the carpet backing to include the inner recesses of the texture of the back.

s

Caution: Inadequate adhesive spread rate, improper application of adhesive, and/or use of low-grade adhesive products are not intended for commercial usage and may void warranties.

 

Double Glue Installations or Double Stick Installations

Installation of Cushion

Cushion should be installed perpendicular to the carpet seams. When this is not achievable, the cushion should be spaced 6 inches or more away from carpet seams. Cushion should be adhered with recommended Signature 2800 or a premium multipurpose adhesive utilizing a 3/32″x3/32″x3/32″ V-notch trowel.

Installation of Carpet Over Cushion

Installer should verify that cushion is secure and bonded to the substrate. This could result in an installation failure if adhesive has not fully cured under the cushion. Once this is verified, the installer should begin the installation of the carpet. The use of Signature 2800 or a premium multipurpose adhesive is recommended utilizing a 1/8″x1/8″x1/16″ U-notch trowel. It is required that all seams be sealed and hot melted with the use of a Double-Stick seaming tape (K-80DS, U-900DS).

9

Note: BioCel backings are not recommended for Double Stick Installations. Any deviations from these installation guidelines will void the manufacturers warranty and the installation company will assume all responsibility.

 

Stretch In Over Pad Installations

This is the recommended installation instructions for carpet with EnviroCel Laminate Plus or ActionBac backings. This method involves the installation of carpet under tension, utilizing tack strip fastened at all walls and other vertical abutments around the perimeter of the area. A separate cushion shall be used.

Tack Strip

Tack strip should be a minimum of 1″ (25 mm) wide and 1/4″ (6 mm) thick. Architectural strip with 3 rows of pins, or 2 rows of conventional strip, should be used in rooms exceeding 30′ (9 m) in length or width. To prevent possible injury to building occupants, the pins on the tack strip should never protrude through the carpet being installed.

Installation of Tack Strip

Tack strip must be fastened securely around the perimeter of the area to be carpeted and at a distance of slightly less than the thickness of the selected carpet from all vertical abutments.

  • Tack strip should be placed with the pins angled toward the vertical abutment.
  • The distance between the tack strip and vertical abutments should not exceed 3/8″ (9 mm).
  • Installation of tack strip across door openings and/or sills should be avoided.
  • Tack strip should be cut to follow the contour of door castings and other irregular-shaped abutments.
  • Carpet should not be stapled to tack strip.
  • Do not drive nails or screws into conduit or tubing on radiant heated floors.

Separate Cushion Selection

The Carpet and Rug Institute (CRI) and the Carpet Cushion Council recommends a maximum thickness of 7/16″ (11 mm) for carpet cushion for residential applications, but in no case should thickness exceed 1/2″ (13 mm). These recommendations may differ, depending on the style, construction and application of specific carpet.

Installation of Separate Cushion

Carpet cushion should be installed in the longest continuous lengths possible, with the seams placed at right angles to the carpet seams or at least 6″ (150 mm) to one side. Cushion should be trimmed flush with the inside contour of the tack strip and securely fastened to the subfloor with staples or non-flammable cushion adhesive at the seams and around the perimeter of each room. With the exception of fiber cushions, seams should also be secured with appropriate cushion tape.

Trimming

Seam edges should be trimmed using tools and techniques best suited for the carpet. Trim edges far enough into the material to maintain structural integrity of the carpet and to successfully join edges without gaps or overlaps.

9

Note: Although “row-cutting” both edges is preferred, other trimming methods may be more suitable with some carpet. Many carpets do not lend themselves to all methods of cutting.

Seaming

The use of the KOOLGLIDE® system is an acceptable method for seaming this backing system. Always have a firm foundation upon which to build your seam. Seam boards are very helpful. Do not under any circumstance build your seam directly on concrete. The cool concrete may suck the heat out of your tape before you have a chance to build the seam. Allow sufficient cooling time before stretching. Cool to the touch is best.

9

Note: When seaming EnviroCel Laminate, the iron setting must never exceed the 3 setting. Run iron at 2 1/2-3. Any hotter will affect the bond of the fleece secondary backing to the precoat. The use of 6″ hot melt seeming tape is also required.

Proper Seam Characteristics

With any method, a properly constructed seam:

  • Has cleanly trimmed edges that are properly secured with seam sealer.
  • Has tightly abutted edges without gaps or overlaps.
  • Maintains reasonable pattern match where applicable.
  • May not be entirely invisible.

Seaming Tips

  • Use knee-kicker to position and flatten carpet.
  • Use conventional row cutter with sharp blade to cut seams.
  • Do not use factory edges for seams, trim in sufficient amount for good edge bond.
  • Evaluate seam prior to installing.
  • Re-cut seam is necessary to achieve desired appearance.

Power Stretching

Carpet must be properly power stretched and firmly hooked onto the tack strip. The use of a power stretcher is mandatory. Devices used as a substitute for, or an attachment to, a power stretcher may cause injury, damage carpet or subfloors, or result in an inadequate amount of stretch and are not acceptable. For patterned carpet, care must be exercised to ensure pattern alignment along walls. The use of a power stretcher, stay-nails, and a deadman may be necessary to achieve proper pattern match at seams and alignment along walls.

Amount of Stretch

Due to the flexibility of the BioCel and EnviroCel Laminate Plus carpet backings, the recommendations for the amount of stretch to be applied should be 1% in both length and width. Slightly less stretch applied in the width as compared to carpet length stretch will usually lessen seam-peaking tendencies.

  1. Loose lay all drops in place in proper sequence. Allow to relax for 24 hours if possible.
  2. Trim and prepare seams per instructions.
  3. Once long and short side is determined, use a power stretcher and deadman to stretch short side to match pattern.
  4. As always, begin pattern matching in center of the drop. This divides the pattern elongation and makes for less work.
  5. Run hot melt seam, making minor adjustments with knee kicker. Run short lengths of seam if necessary. Allow to cool and re-adjust as needed.
  6. The best way to determine pattern match is to stand back and sight down diagonals formed by pattern.
s

Caution: Wrinkling and buckling are most ofter caused by the failure to adequately stretch the carpet using a power stretcher, the use of an inappropriate cushion, adverse temperature and humidity conditions, or inadequate conditioning time. Failure to power stretch a carpet my result in wrinkling and buckling over time, localized damage to the carpet, or delamination.

Cutting and Seaming

Carpet with BioCel or EnviroCel backings require seaming techniques similar to conventional commercial broadloom backing. Two (2) methods are listed below. Seam sealer is required.

  • Preferred Method — Row Cut / Row Cut – The preferred seam cutting method, especially for patterned products.
  • Alternative Method — Row Cut / Trace Cut – Primarily for non-pattern products or when the preferred method is not able to make an acceptable seam. Avoid cutting loops and never make a serpentine cut.

Seam Sealing

All of Signature’s carpets require seam sealer for edge-ravel and delamination properties. Use an applicator or plastic squeeze bottle with an adjustable nozzle and apply a 1/8″ bead of seam sealer to the edge of the first length seam at the primary backing level. Using the proper amount will ensure tight seems. Exercise care to prevent seam adhesive from getting on the carpet face.

Remove Excess Seam Adhesive

Seam adhesive will transfer to the adjoining edge and seal the seam. Remove excess seam adhesive along seams with a cleaning solvent using a white cloth. Do not flood the seam with cleaning solvent. Follow solvent manufacturer’s instructions regarding proper use of solvent.

 

Installation Complete

  • Roll surface: Roll entire installation with a 75 lb. carpet roller.
  • Trim Perimeters: Use a wall trimmer or carpet knife to trim along wall edge.
  • Transition Strips: To prevent edge raveling at transition borders (wherever carpet meets hard surface flooring), transition strips are required.

 

Stair Installation

Stairs With Nosing

Carpet should be installed with one piece covering tread and nosing and another piece covering the riser. Measure both left and right sides of each step accordingly. A minimum rounded edge nosing is recommended.

Stairs Without Nosing

Carpet should be installed in a single piece covering both tread and riser. Measure both left and right sides of each step accordingly.

9

Note: When installing on straight stairs, for maximum adhesion use non-flammable permanent contact adhesive on the nosing, carrying over 2″-3″ on the tread and riser. Apply the same adhesive to the corresponding area on the back of the pre-cut carpet.

After Installation

Vacuuming

Before the area is occupied, the entire installation should be vacuumed with an upright, cylindrical brush type vacuum cleaner.

Protect Until Occupancy

Protect carpet from other trades people and heavy traffic until occupancy. If furniture or other equipment is to be rolled over installation, provide plywood or Masonite sheets in traffic paths. Plastic film should not be used as carpet protection as it retards adhesive curing.

Hot Water Extraction

As with any direct glue-down installation, to ensure complete adhesive curing, do not hot water extract for at least 30 days after carpet installation.
