MATERIAL FOR THE JOB

1. Calculating MULTIPLY Underlayment

One panel covers 16 square feet. Measure the floor and add another 5% to 10% to allow for cuts and scrap material.

2. Selecting the Fasteners

  • Tight fastening is extremely important to help prevent panels from lifting loose. Three methods are approved however staples are fast to install, lower cost and set neatly to avoid patching indentations.
  • Fastener must recess 1/16” below the surface and penetrate 75% to
  • 90% of the subfloor assembly but not protrude through the bottom. Select a coated fastener known not to stain vinyl, stone, or marble floor covering.

Staples:

(preferred fastener for vinyl floors)
Narrow crown chisel point staple, 7/32” or 1/4” – either
clear polymer coated or galvanized.

Nails:

(preferred fastener for ceramic tile)
Ring shank or annular-grooved, galvanized flooring nails with
a 3/16” diameter head. Recess 1/16” and patch over.

Screws:

Flathead countersunk wood screws.
Do not use drywall screws. Recess 1/16” and patch over.

3. Using Patch / Fillers

  • It is Multiply’s experience that filling or flashing joints between panels with patch may increase the risk of tunneling and/or ridging over these joints – use only when absolutely necessary.

  • We recommend all normal panel joints be sanded and not patched. If gaps, chips, etc. occur, use a cement-based high-solid, non-shrinking acrylic patching compound approved by the vinyl flooring manufacturer.

    Do NOT use gypsum-based patching compounds. Use a brand name product and manufacturer’s acrylic latex additive for improved results versus mixing with water. See ACCLIMATION - Moisture & Movement below.

4. Safety Equipment

Warning: Wood dust can cause eye and breathing problems: wear protective gear:

  • Dust Mask
  • Safety glasses or eye goggles
  • Kneepads
