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 the required seaming system for residential linoleum installations and an alternative to heat welding in commercial installations 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. 5).
  7. Roll the seam using a hand roller (Fig. 6).
  8. Remove burr at the seam by carefully skiving with the back of the linoleum knife (Fig. 7).
