VI. Installation – Laying out materials
1. Assume that the walls you are butting against are not straight or square. Using a chalk line, make a
starting point for an edge of the flooring to follow. The chalk line should be set where the first seam will
be located.
2. Lay the rolls on the floor in a way that will use your cuts efficiently. Cut all rolls at the required length,
including enough to run up the wall a couple inches.
3. If end seams are necessary, they should be staggered on the floor and overlapped approximately 2".
End seams will be trimmed after acclimation period using a square to ensure they fit tightly without
gaps.
4. After allowing proper acclimation and rough cuts are made, you may begin the installation.
5. Align the first edge to the chalk line.
Note: it is very important that the first seam is perfectly straight.
6. Position the second roll. Edges should fit snug with no visual gaps. Care should be taken to not over
compress the seam. Over compressed seams will cause peaking.
7.
Repeat for each consecutive sheet necessary to complete the area or those rolls that will be installed
that day.
VII. Installation – Adhesive Application
1. After performing the above procedures, begin the application of the adhesive. We recommend E-Grip
III, a one-component moisture-cured polyurethane adhesive. E-Grip III should not be mixed. It is
specially formulated for use right out of the pail. Apply E-Grip III to the substrate using a 1/16˝ square-
notched trowel.
2. Do not allow adhesive to be forced up into the seam or this will interfere with sealing the seams and
create a discolored line at the seam.
3. Fold over the first drop along the wall (half the width of the roll). Rolls are 6 feet wide, so when roll is
folded over this will leave an exposed area of substrate that is 3 feet wide.
4. Spread the adhesive, taking care not to spread more E-Grip III than can be covered with flooring within
30 minutes. The open time of the adhesive is 30–40 minutes at 70°F and 50% relative humidity.
NOTE: Temperature and humidity affect the open time of the adhesive. Temperatures above 70°F and/or
relative humidity above 50% will cause the adhesive to set up more quickly. Temperatures below 70°F
and/or relative humidity below 50% will cause the adhesive to set up more slowly. The installer should
monitor the on-site conditions and adjust the open time accordingly.
NOTE: Do not allow E-Grip III to cure on your hands or the flooring. Immediately wipe off excess adhesive
with a rag dampened with mineral spirits! Cured adhesive is very difficult to remove from hands. We
strongly suggest wearing gloves while using E-Grip III.
5. Lay the flooring into the wet adhesive. Do not allow the material to "flop" into place; this may cause air
entrapment and bubbles beneath the flooring.
6. Immediately roll the floor with a 75–100 lb. roller to ensure proper adhesive transfer. Overlap each pass
of the roller by 50% of the previous pass to ensure the floor is properly rolled. Roll the width first and
then the length. Roll again within the first 60 minutes.
7. Fold over the second half of the first roll and half the width of the second roll. Taking roll widths into
account, this will provide an exposed area of substrate that is 6 feet wide. Spread the adhesive, roll the
flooring, and repeat for each consecutive drop.
8. Continue the process for each consecutive drop. Work at a pace so that you are always folding material
back into wet adhesive bed.
NOTE: Never leave adhesive ridges or puddles. They will telegraph through the material.
