Description

MS003 is an acrylic floor preparation solution designed to improve flooring substrates before the application of floor-covering adhesives. MS003 will improve dry, porous substrates for a better bonding surface, help protect the adhesive from alkalinity damage and improve adhesive spread rate. MS003 is suitable for use over APA approved flooring grade plywood, concrete or acoustical concrete and floor patch and can prevent over absorption of adhesives resulting in a better bond. MS003 may also be used as a primer for gypsum-based substrates prepared in accordance with ASTM F2419. MS003 is designed and warranted for use only in conjunction with MSI adhesives.

 

BEFORE YOU BEGIN:

Important: Proper substrate preparations are essential. Moisture testing must be performed and documented before installation begins.

 

SUBSTRATE CONDITIONS:

Use on concrete substrates on or above grade with up to 85% RH and a pH reading of 8.0–12.0 Not to be used as a moisture sealer or adhesive encapsulant. Do not use without performing a bond test first. Do not use MS003 in combination with any other manufacturers’ adhesive. It is up to the installer to determine proper application based on jobsite conditions. Do not allow product to freeze.

 

USAGE:

Use on concrete substrates to block high surface pH conditions. Substrate must be clean and dry. Moisture test results must not exceed 85% in-situ Relative Humidity (ASTM F 2170), and surface pH should not exceed 12.0. Mechanically remove all existing adhesive ridges, leaving surface smooth and make certain substrate is free of oil, grease, sealers or curing agents, adhesive residue or any material that would prevent adequate coating. Apply MS003 as an even coat over the entire surface of the floor. Only one coat is required. Allow MS003 to dry for a minimum of 4 hours, or until completely dry and hardened to the touch.

 

USE OVER:

APA approved flooring grade plywood.

On or above grade concrete.

Acoustical concrete.

Floor patch.

 

APPLICATION:

3/8” nap roller: 350–400 square feet per gallon – Make certain to keep the applicator roller wet with material.

Sprayer application: 400–500 square feet per gallon – Overlap spray pattern to ensure full coverage.

Do not use MS003 if solvent or chemical cleaners have been used. Patching or leveling of substrate must follow all manufacturers’ application and curing instructions prior to applying MS003. Perform a bond test with MS003 over any patching compound before general application of either. Do not use MS003 in combination with any other sealer or encapsulant. Do not use MS003 to encapsulate cutback adhesive residues. MS003 cannot be used as a moisture sealer. The floor and room temperature, as well as the MS003 should be between 65°–95° F and the humidity should be between 10%–65% for 48 hours prior to, during, and after the installation. MS003 is not recommended for use in conjunction with polyurethane based adhesives.

 

CLEAN UP:

Clean up spills with soapy water. Dried residues may require the use of a solvent cleaner. Containers must be kept tightly closed when not in use.
