Install Self-Leveling Cement over Plywood or Wood Subfloors

Param 5500, self-leveling cement has been successfully used over plywood or wood subfloors. The wood subfloors must be a minimum of 3/4" thick, tongue and groove, untreated, APA Rated, Type-1, exterior grade, plywood, OSB or equivalent. The deflection in the subfloor must NOT be more than L/360, considering both live and dead loads in both the directions.

Surface Preparation: The surface of the wood must be clean and free of oil, grease, wax, coatings and any contaminant that might act as a bond breaker. We recommend sanding the surface to bare wood. The surface should not have any sheen. Replace any weak or water damaged wood. Secure loose boards with deck screws. Using a fiber glass tape and rapid setting polymer modified cement seam the joints in the wood subfloor.

Priming: Apply one thin coat of Paramol (Param Premium Primer UNDILUTED using a 3/8" nap roller. Ensure that there is no puddling of the primer anywhere on the subfloor more importantly do not miss any areas during the priming. Brush off puddles and excess primer. Allow the primer to dry for 6 to 8 hours but no more than 24 hours. If it has dried more than 24 hours another coat primer will be necessary,Once the primer is dry and tack free, install galvanized, expanded diamond metal lath mesh, stapling approximately every 6 inches. Overlap adjacent ieces of lath mesh approximately 1". After the lath is placed, allow Paramol to dry thoroughly as mentioned above.
