Quality Engineered Hardwood Floor Installation Instructions

Before You install engineered hardwood flooring

Sub-Floor Preparation to install Engineered Hardwood Flooring:
• The sub-floor must be completely dry. A new concrete slab will usually take 90 to 150 days to dry thoroughly
depending on size of slab and weather conditions. The moisture content difference should be no more than 4%
between the engineered wood floor and concrete sub floor.
• If plywood is used as a sub-floor, the moisture content difference should be no more than 4% between
engineered wood floor and plywood sub floor. Plywood size for sub-floor is suggested to be ¾” x 48” x 48” and
leave ¼” between sheets for expansion.
• The sub floor must be free from any type of paint, oil, greases, dust and all other types of residues.
• The sub floor should be level. The level drop must be no more than ¼” over a 10 feet distance.
Glue-down installation guidelines for QUALITY ENGINEERED Hardwood Floors:

baseline of installation.
• Following the spread rate, curing time, spread the glue evenly on the sub-floor to cover the area the installer can
lay the planks in time for best result of the glue.
• Lay one row of plank along the entire length of work line. Add each additional row of flooring, watching the
pattern repeat and offsetting or staggering the joints at least 6 inches.
