Installation Systems \ Vinyl and Linoleum Sheet\Flash Cove Installation System



A. TOOLS
In addition to the normal tools (knives, dividers, recess scribers, straightedges, rollers, trowel, etc.), other tools are also needed for flash cove work:
  1. Chalk line - to set cap strip on straight line
  2. Carpenter's square
  3. Throwaway brushes - to spread adhesive on cove stick and wall
  4. Heat gun - to warm vinyl so it is more pliable and less likely to break (particularly with heavier material)
  5. Patching compounds - to patch juncture of wall and floor or repair wall if former flash cove installation is removed
  6. Cloths and cleaner - to clean adhesive residue from surface of material
  7. Felt paper - to pattern scribe (templates or full patterns)
  8. Miter box and saw - to fit cove stick and cap strip

B. INTRODUCTION
Armstrong floors should not be used as wall covering or wall surfacing. Most Armstrong sheet floors can be flash coved (integral cove). Most building codes consider flash coving in the same category as baseboard trim with respect to fire rating. Consult applicable codes for the particular project to determine the interpretation of allowable height for flash cove (a maximum of 8").

Flash coving is an extension of the sheet flooring up the wall to form a wall base. This can be accomplished by either one-piece flash coving, border flash coving, or two-piece flash coving. All seams in the flash cove area should be treated the same as seams throughout the rest of the installation.

Adhesive:
Vinyl-backed commercial flooring must be adhered with S-580 in flash cove areas. Linoleum, fiberglass-backed, felt-backed flooring can be adhered with either the field adhesive or S-580 in flash cove areas. Apply two coats of S-580 Flash Cove Adhesive with a brush or roller 4" on the floor as well as up the entire cove area. Allow adhesive to dry to a pressure-sensitive state between applications. Armstrong S-580 Adhesive has unlimited working time.

Nail or cement a cap or binder strip to the wall at the desired height. Install a cove stick at the juncture of the wall and floor to support the material where it coves up the wall (Fig. 1). If there is no support behind the material, it can be punctured. Usually cove sticks will have approximately a 7/8" radius, although other sizes are available.

Prepare the subfloor the same as for a flat installation with the exception of the wall preparation.
