INSTALLATION GUIDELINES FOR FLATWOVEN PRODUCTS
- Given the nature of this construction, no seam will be invisible. End-user should be made aware of this prior to installation.
- It is absolutely critical that every cut edge, including seams, perimeters and openings are sealed. Sealer should be applied with a 1/8” bead. This should be done immediately after cutting, but latex should still be “tacky” when creating a seam.
- Allow carpet to acclimate to room conditions for at least 12 hours. Stanton recommends 24 hours when possible.
- All products with repetitive patterns require that installations involving multiple rolls be sequenced, installing rolls with the longest pattern repeat first and moving towards installing rolls with short repeats last. This allows shorter pattern repeats to be stretched to fit longer ones. Match all patterns in center of seam and work towards the ends.
- Recommended under lays for these products include flat solid rubber (18 lb minimum density) or fiber cushions (synthetic felts) with a minimum weight of 40 oz/sy.
- Attach proper cushion to the floor, ensuring that no carpet seam will be traveling parallel within 6” of the cushion seam. Stanton requires architectural tackless strips to be used (J pins). Strips should be placed 3/16” from walls.
- Cuts should be made from the top using a cushion back cutter.
- In the event of pins protruding through the surface of the carpet, use thin felt pressed over the tacks to “build up” the base on the tackless strip prior to attaching carpet.
- Ensure that patterns are squared and aligned during the initial layout and continue throughout the seaming and power stretching procedure.
- Planning and care should be taken in determining the proper location for the lengthwise cut for a seam. Depending on the style (pattern), the cut should be made so as to cut through as few weft (widthwise) accent yarns as possible. When viewed from the back, you will notice a white line running in the length direction. The first cut should be made next to this line. This will eliminate most fraying, but this edge still requires latex.
- To greater ensure the durability of seams when installing patterns with top warp yarns that are spaced ¼” or greater, the following steps need to be followed:
- 1. Strip 1 ½” inches of warp yarns away from the seam edge on either side of the seam.
- 2. Trim away filler weft yarns without disturbing weft accent yarns.
- 3. Fold under exposed accent weft yarns and glue to the back of the carpet to ensure the accent yarns will not fray after the seam is made.
- 4. Complete seam using standard CFI installation guidelines.
- When welding the seam, loose yarn must be worked down into the seam.
- Stanton recommends premium 6” seaming tape to attain a good bond at seam areas and to avoid seam peaking.
- Conventional seaming irons should be set no higher than 2.5 to avoid burned or distorted seams. A non-heat conductive weight should be used to smooth the seam. Star tractors are not recommended.
- When installing via direct glue down, the substrate should be clean and dry. A high quality, latex adhesive with high solids content should be used, applied with a 1/8” x 1/16” “U” shaped trowel at a spread rate of 10 -12 square yards per gallon, and should be allowed to flash off before laying the carpet into it to prevent the glue from coming through the material and onto the face. It should be stringy or tacky before adhering the carpet to the substrate. The carpet should never be laid in wet. The material should be rolled with no more than a 35-pound roller.
