3 EXECUTION

3.1 EXAMINATION

3.1.1 Do not begin installation until substrates have been properly prepared.

3.1.2 If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.

3.2 PREPARATION

3.2.1 Clean surfaces thoroughly prior to installation.

3.2.2 Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

3.2.3 All subfloors must be smooth, dry, clean, flat and free of dirt, grease, wax, paint, oil or anything that would hinder a good bond.

3.2.4 Trisodiumphosphate (TSP) can be used to clean vinyl surfaces. Concrete subfloors not meeting this standard must be scoured with 3-1/2 open coat paper (20 grit), then vacuumed clean.

3.2.5 When installing over existing hard surface floors, remove finish to allow a good mechanical bond.

3.2.6 Do not install over old "cutback" petroleum adhesives. These must be removed completely or covered with a Portland cement leveling compound.

3.2.7 When installing wood flooring over gypsum based levelers, the gypsum must first be sealed/primed and allowed to dry prior to installation of wood flooring (see gypsum manufacturer's instructions for recommended sealer/primer).

3.2.8 Complete drying of leveling compounds is critical before installation. While curing time may only take a few hours, the complete drying time of these compounds can take 24 hours or more.
