Seal Pro MS300
Clear Exterior / Interior Deep Penetrating Sealer
Seal Pro MS300 is a clear, deep penetrating, non-yellowing solvent base sealer designed for concrete substrates. It is resistant to chemicals, oils, grease, transmission and hydraulic fluids. It protects against the attack of water borne salts, acids and alkali’s. It helps block the effects of efflorescence in concrete. Its high perm rate allows ready transmission of moisture vapor.
Seal Pro MS300 may be used as a surface densifier and or dust proofing on concrete. In applications where maximum protection is desired, Seal Pro MS300 should be applied as a deep subsurface seal with a final coat of SP600 as a protecting topcoat.
SURFACE PREPARATION: The surface to be treated must be free of all oil, dust, dirt and other contaminants. Power washing and thorough rinsing is the preferred method of surface preparation. Surface imperfections and cracks larger than 1/16” should be repaired with caulk or other filler material. All caulks and repair materials should be in place and cured prior to the application of Seal Pro MS300.
