Installation

Subfloor Preparation - Remove all dirt, oil, loose paint, old adhesive, wax, sealers, curing agents, and other contamination from all working surfaces by general abrading. When sandblasting, shot blasting or scarifying, surface texture must be similar to light broom finish concrete. Maximum acceptable floor variation is 3/16” for a 10ft length. Surface areas requiring patching or leveling must be done using portland based cementious patching materials. All loose material must be vacuumed from the surface before application. Maintain FloorSecure at room temperature before applying to ensure easy troweling and leveling. Test and evaluate to ensure adequate adhesion. Subfloor Moisture Check - Prior to the installation of FloorSecure on a concrete subfloor, CHEMLINK recommends that a Calcium Chloride test be performed to check for moisture pressure. When performing this application, it is recommended that several locations on the substrate are to be tested. The concrete subfloor is not to exceed 15 lbs./1000 sq. ft./24 hours per Calcium Chloride Test (ASTM F1869) or 85% relative humidity when tested with an in situ probe (ASTM F2170). For installations on wood substrates, acceptable conditions are moisture readings less than 12% when using a Tramex, Delmhorst, or an equivalent wood moisture meter. Installation - Begin installation by securing a starter row to the subfloor. The starter row provides a stationary point to push against and prevent flooring shift during installation. Once the starter row is secured, apply adhesive to substrate with the appropriate trowel. Spread the adhesive and begin to install the flooring immediately. For “walk-on-work” installations, immediately clean any adhesive from pre-finished flooring with solvent. Be careful not to harm the finish of the flooring. Buff the flooring with a dry rag or paper towel. If required, after a few rows have been installed, secure the flooring boards with removable tape to prevent sliding. Flooring that is not flat should be tacked, weighted, or rolled to ensure proper contact between the flooring and substrate. Rolling is recommended for all installations with a 150 lb. roller within 30 minutes of application. Available only through Chem Link distributors.
