Inspect concrete sub floor for any open cracks and fill with high-grade epoxy filler. Remove any excess concrete lumps or residue that may interfere with the installation of the underlayment.

Sub floor should be properly sloped, structurally sound, level, and clean. Good grade plywood that does not exceed deflection of L/360 of span including live and dead loads should be used.

Tools needed for installation
Utility Knife
Measuring tape
Straight edge

Any solvent free acrylic emulsion adhesive used to adhere non-porous underlayment to the sub floor such as Apac 564 or Impacta T-700 bond coat. Always test area prior to full installation to insure transfer and bonding.

1.) Bond VC300 to the sub floor making sure to check for bonding & transfer.
2.) Lay the VC300 into the adhesive and flat trowel from the center outwards to remove all air bubbles and insure contact with the adhesive.
3.) Roll the VC300 using a 125 lb roller, from end to end and side to side to insure overall contact.
4.) Leave a 3mm gap around the entire perimeter to allow for expansion and contraction.
5.) Use a utility knife and a straight edge for cutting to size and insure that edges are butted tightly together.
6.) After 30 min, when floor has been completely covered, roll again to ensure contact is maintained.
7.)Do not apply loads on VC300 until adhesive has fully set.

1.) The vinyl flooring shall be bonded to the VC300 using an acrylic adhesive that is acceptable for dry setting installations over non-porous material, taking care to follow manufacturer’s written instructions.

2.) Allow the adhesive to cure before allowing foot traffic on it.
