For direct glue installations, Bow and Skew must be dealt with on each breadth individually. To accomplish this it is most efficient to change the method in which the carpet is pulled back to allow the spreading of the adhesive. As a first step the location of the first seam is established with a chalk-line. Instead of folding the carpet back from the seam, it is more efficient to roll the carpet up from the ends to the middle. Adhesive is applied to an area approximately 11 feet wide by 10 to 15 feet long. The carpet is carefully rolled into the adhesive insuring that the edges fall onto the previously established chalk-line with the bow and skew adjusted using a power stretcher to a dry line that is straight and parallel to the end walls. This procedure is repeated until the first breadth is straight and square to the area. The second breadth in the sequence is brought in and a match point is established close to the center of the seam. The same rolling up and adhesive application process is performed insuring that the pattern is matched and the bow and skew are effectively removed in each section. The six inches left unglued under the first breadth is adhered during this process leaving six inches unglued on the opposite edge to allow that seam to be assembled.Trueness of EdgeTrueness of edge will show up on an installation as trimmed seam edges that do not form a completely straight line. This will result in a seam that has tight areas and gaps. The most effective way to deal with this is to butt the “lowest” point of the seam together such that all other areas of the seam are either net or overlapped. The edges should be folded back with a 3 to 4 foot wide strip of the recommended adhesive applies to both side. Both sides should be laid into the adhesive. Working from the areas that are well butted the carpet should be pushed away from the seam until the tight and overlapped areas are also net. This will result in wrinkles running roughly parallel to the seam that must be worked into the adhesive by pushing the wrinkle away from the seam. It may be necessary to use a minimal number of stay nails to secure the seam in position and to insure it remains properly abutted until the adhesive dries. Once the seam is secure and well butted, the Glue2® tip should be inserted and the edges sealed.Pattern Elongation:As stated above, the most elongated pattern must be installed first, then the next longest, etc. This allows stretching of the shorter pattern to match the longer pattern and keeps the closest pattern repeats together. After the roll sequence is established as noted above, glue half of the long pattern and half of the shorter pattern lengthwise. Stretch the shorter pattern to match the longer pattern by establishing a match in the center of the seam and stretching toward the ends in short increments of three to five feet along the “shorter” side of the seam. As a general rule the more variation that is present, the shorter the increment that can be brought totally into match. In severe cases, there are thermoplastic seaming tapes such as Orcon K-80TM that are engineered specifically for adhesive installations that allow each increment of the seam to be melted together and secured as it is brought into match. This tape is very low profile. In addition the paper backing is easily removable after the seam is assembled so that there is essentially no telegraphing of the tape. Using thermoplastic seaming tape to secure the seam essentially eliminates the need for stay nails and all of the potential issues associated with their use on direct glue or double stick installations. This also creates a much stronger seam that is virtually waterproof and highly resistant to damage from downstream maintenance.Applying Approved Adhesive for Direct Glue Down:To make certain that the proper amount of adhesive is applied a 1/8" x 1/16" x 1/8" V-Notched trowel must be used. This will result in a spread rate of 10 to 12 yards per gallon. Higher spread rates and different adhesive types are used when the double glue method of installation is used.PAGE 115INSTALLATION INSTRUCTIONS shelmarccarpets.com | 888.504.3100 Designs protected by US Copyright laws
