4. Fitting
 Your vinyl sheet flooring should be unrolled and allowed to lay flat in a separate room or area with
similar conditions as the installation area.
 Do not lay it out over carpet or other soft surface. The subfloor should be solid to prevent
distorting the flooring while working or walking on top of it.
 Pre-cut the pieces accurately. It is much easier to cut pieces close to size in an area where you
can lay them out flat. Generally, allow 1-1/2” (31.8 mm) for each end wall. (With two or more
pieces, make sure you have cut them long enough for pattern matching purposes.)
 Cut seams net. Pieces that are cut and fit in the morning should be adhered that morning.
Pieces that are cut and fit in the afternoon should be adhered that afternoon.
 When installing over an existing resilient floor, lay out the installation so the new seams are a
minimum of 6” (15.2 cm) away from the original seams. When going over tile floors, seams
should fall in the center of the tile.
 Recommended fitting procedures include straight scribing, pattern scribing and freehand knifing.
 Make a final check to be sure your prepared subfloor is clean, dry, flat and dust-free.
 Carefully reroll the new flooring with design side out and take into the room.
 Unroll it and position in the room taking care not to distort it by creating or putting sharp folds into
it.
 Inspect around walls, cabinets, etc. to be sure that an adequate expansion zone of 3/16” to 1/4"
exists at all vertical surfaces and that the flooring can freely slide beneath doorway trim.
 Make safety cuts so it will lay flat on the floor. This will make final fitting easier and prevent the
material from tearing.
 Cut material slightly loose and away from walls wherever molding or wall base will be used to
cover the edge of the vinyl.
 Flooring should be laying flat and “balanced” in the room.

Open Time: 0–20 minutes
over wood or concrete
Regular Notch: 1/16" (1.6
mm) deep, 1/16" (1.6 mm)
wide, 3/32" (2.4 mm) apart
Open Time: 10–20 minutes over existing resilient
flooring or other nonporous substrates
Fine Notch: 1/32" (0.8 mm) deep, 1/16" (1.6 mm)
wide, 5/64" (2 mm) apart
NOTE: Allowing the proper open time will help to minimize knee marks, roller marks and
trapped air blisters. The amount of open time will vary according to job conditions, temperature,
humidity, air flow and type of substrate.
 All fitting should be complete before spreading adhesive.
 Use Armstrong S-235 or S-254 Adhesive as specififed for the particular product being installed
and use the proper trowel notching.
 Apply the adhesive to the subfloor one half of the sheet at a time. Lap or tube back one half of
the sheet to expose the subfloor.
 Allow the recommended open time before placing the material into the adhesive. Do not roll the
product face in while spreading adhesive.
 Starting at the center and working toward the edges, roll in two directions using a 100-lb. roller.
 Clean excess adhesive from the surface of the flooring using a clean, white cloth dampened with
detergent and water.
