COMMERCIAL SHEET INSTALLATIONS S-761 Seam Adhesive Procedure

S-761 Seam Adhesive helps significantly reduce installation time compared to traditional seaming methods and allows for a broader range of installer skill sets. It is an alternative to heat welding in commercial installations of vinyl sheet flooring where an impervious floor covering is not required.

Note: Armstrong S-761 Seam Adhesive is not recommended in health care operating rooms, procedural rooms or any space where an aseptic environment is necessary. Heat-welded seams are recommended for those types of applications.        

1. Use a recess scribing tool to recess scribe all seams net (Fig.1).
2. Insert a piece of scrap material beneath the scribe mark. With the scrap on the same side as the cutting hand, cut the seam at a 90-degree angle. Be sure to hold the knife blade straight up and down (Fig. 2).
3. Remove the scrap piece of material.
4. Using the applicator bottle, apply a 1/8″ bead of S-761 Seam Adhesive along the seam edge (Fig. 3).
5. Tuck the seam edge into place, forcing the S-761 Seam Adhesive up through the seam (Fig. 4).
6. Clean adhesive residue from the surface of the flooring using a clean, white cloth dampened with neutral detergent and water (Fig. 6).
7. Roll the seam using a hand roller (Fig. 7).
8. Remove burr at the seam by carefully skiving with the back of the linoleum knife (Fig. 8).
9. Roll immediately in both directions with a 100-lb. roller.

RESIDENTIAL SHEET INSTALLATIONS – S-761 Seam Adhesive Procedure

See attached file below for illustrated instructions.

S-761 Seam Adhesive helps reduce installation time significantly compared to traditional seaming methods.

Modified Loose Lay Installations

1. Double-cut the seam before applying the vinyl tape or adhesive.
2. After seam is cut, fold back both edges and apply the tape or adhesive.
3. After applying the tape or after proper open time with the adhesive place one side back down.
4. Using the applicator bottle, apply a 1/8″ bead of S-761 Seam Adhesive along the seam edge.
5. Tuck the seam edge into place, forcing the S-761 Seam Adhesive up through the seam.
6. Clean adhesive residue from the surface of the flooring using a clean, white cloth dampened with neutral detergent and water.
7. Roll the seam using a hand roller.
8. Allow 2 hours before foot traffic and 4 to 6 hours to fully dry for rolling loads.

S-295 or S-299 Full Spread Adhesive Installations

1. Double-cut the seam dry before applying the adhesive.
2. After seam is cut, fold back both edges and apply the adhesive.
3. After proper open time (dry-to-touch over non-porous substrate) place one side back down.
4. Using the applicator bottle, apply a 1/8″ bead of S-761 Seam Adhesive along the seam edge.
5. Tuck the seam edge into place, forcing the S-761 Seam Adhesive up through the seam.
6. Clean adhesive residue from the surface of the flooring using a clean, white cloth dampened with neutral detergent and water.
7. Roll the seam using a hand roller.
8. Roll immediately in both directions with a 100-lb. roller.
9. Allow 2 hours drying before foot traffic and 4 to 6 hours to fully dry for rolling loads.
