Installation Instructions

1. Prepare all substrates according to flooring manufacturer's guidelines.
• All substrates must be dry, solid, stable, and structurally sound. Application surface must be level within 3/16"
• All substrates must be cleaned of any dust, dirt, oil, grease, paint, curing agents, concrete sealers, loosely bonded toppings, loose particles, old adhesive residues, and any other substance or condition that may prevent or reduce adhesion.
2. Key the adhesive into the surface of the substrate using the flat side of chosen trowel.
3. Spread adhesive evenly over the subfloor, keeping the trowel at a 45-degree angle to the surface.
• Do not spread more adhesive than can be covered with floor covering within 30 minutes.
4. After spreading the adhesive, immediately install the flooring material into the adhesive while it is still fresh.
• Periodically lift the material to confirm more than 90% adhesive transfer to the backing.
5. Roll the flooring surface across the width and length with the manufacturer’s recommended roller to break down adhesive ridges and to ensure complete removal of trapped air.
• Pull (rather than push) the roller, so that footprints are not left on the floor.
• Apply weights at the seams to maintain contact until the adhesive sets (recommended).
6. Complete the installation per the flooring manufacturer’s instructions.
