. The material is
flexible and will handle easily when cutting and fitting. The material must always be cut flat before final cuts are made, leaving a
1/8” to 1/4” expansion gap. Never allow the material to become twisted. Always fold the material in a wide radius to avoid
sharp kinks and creases that may cause breaks in the backing. You may flash cove

foam backing has important printed information which identifies product name and
production dates. The distinctive printed pattern is also helpful during installation while cutting in the product. The printed
arrows become useful when identifying material direction for seaming.
ONE PIECE INSTALLATION
Thoroughly clean the subfloor, sweep or vacuum to remove all dust and debris. Remove any quarter round, shoe base or wall
base, and undercut any doorways. Precut the floor covering to fit the area, allowing 2” to 4” extra length and width for fitting.
Position the resilient flooring in the room, allowing enough material to drop into offsets, closets, alcoves, etc.
Align pattern squarely in room, parallel to all walls. If the room is not square, align the pattern so the run-off is located in the
least conspicuous area. After the sheet is positioned, weight it to prevent shifting. Make relief cuts around unusual objects such
as pipes, fixtures, floor registers, etc. Make relief cuts on all inside and outside corners. Rough-cut the sheet to remove excess
material. Trim and fit the perimeter so the floor covering lies flat.
FULLY ADHERED- PERMANENT BOND
When using the Permanent Bond method, apply the adhesive with a 1⁄16” wide, 1⁄32” deep, and 1⁄32” apart notched trowel.
After trimming the material to fit the room, tube or lap it back to expose approximately one-half of the under floor; strike a
white chalk line near the fold of the material. This line provides a guide for adhesive application. Spread the adhesive, leaving
no gaps, voids, puddles, or thin spots, over 100% of the exposed under floor. Keep the trowel clean and properly notched to
maintain this uniform coverage. Immediately after adhesive application, gently position the sheet into the adhesive. Roll the
floor covering forward into the adhesive to eliminate trapping air. Do not drop or flop the material into the adhesive. Using a
50 lb. (or heavier) three-section floor roller, roll the material in both directions, starting in the middle of the sheet width and
rolling toward the edges. This process eliminates air and embeds the floor covering into the adhesive. For areas that cannot be
reached with a floor roller, use a hand seam roller.
Failure to roll the floor covering can result in the following problems:
• Lack of bond between material and underfloor.
• Telegraphing of adhesive ridges.
• Permanent indentations: when heavy items are placed on the new flooring, resulting from adhesive displacement.
Once the first half of the material is adhered and rolled, fold back the second half and repeat the procedure. When folding back
the sheet use extreme caution to prevent tearing the backing at the glue line. Also, be careful to regulate the adhesive spread
at the glue line. This will avoid an adhesive ridge left in the center of the sheet.
FULLY ADHERED - RELEASABLE BOND
When using the Releasable Bond method, apply the adhesive with 3/8” nap paint roller.
After trimming the material to fit the room, tube or lap it back to expose approximately one-half of the under-floor. Strike a
white chalk line near the fold of the material. This line provides a guide for adhesive application. Spread the adhesive, leaving
no gaps, voids, puddles, or thin spots, over 100% of the exposed underfloor. Keep the paint roller clean to maintain this
uniform coverage.
Allow the adhesive to dry, and then gently position the sheet into the adhesive. Roll the floor covering forward into the
adhesive to eliminate trapping air. Do not drop or flop the material into the adhesive. Using a clean, soft-bristle push broom,
smooth the material in both directions, starting in the middle of the sheet width and working toward the edges. This process
eliminates air and embeds the floor covering into the adhesive. For areas that cannot be reached with the broom, use a hand
seam roller.
Once the first half of the material is adhered and smoothed, fold back the second half and repeat the procedure. When folding
back the sheet use extreme caution to prevent tearing the backing at the glue line. Also, be careful to regulate the adhesive
spread at the glue line. This will avoid an adhesive ridge left in the center of the sheet.
