Armstrong Flooring S-454 Prime Strong Porous Primer, 2.6-Gallons, is an acrylic primer for porous substrates to add strength for a better adhesive bond and to reduce subfloor absorbency. Use S454 Prime Strong Porous Primer with all Armstrong Flooring resilient adhesives for the installation of Armstrong Commercial Linoleum Sheet, VCT, BBT, Commercial LVT, Commercial Sheet Vinyl and Commercial Rubber Tiles. Apply with brush or roller. Spread rate will vary dependent upon dilution or undiluted primer application.

• Strengthens adhesive bond.
• Contains Zero VOCs.
• Dries quickly.
• Bonds to all Armstrong Flooring patches and underlayments.
• For use on porous substrates.

Use Armstrong S-454 as primer on porous concrete, wood, cement based underlayment, water resistant adhesive residue, and gypsum substrates including drywall. For porous cement based substrates and porous concrete apply S-454 Prime Strong diluted 1:3 with water. On gypsum based substrates apply Prime Strong Porous Primer diluted 1:1 with water. Other application may require no dilution depending on porosity of subfloor material. Drying time is typically 10 minutes on concrete, cement and gypsum based substrates. If cement based products (such as underlayments or thin-sets) will be applied on gypsum substrates, allow approx 16 hours prior to use of these products.

All surfaces must be clean and free of dirt, oil, grease, plaster, curing compounds, old adhesive residue and other foreign matter before applying S-454. Concrete floors must be tested for porosity in accordance with ASTM F-3010 and be free of excess moisture and/or alkali. It is the responsibility of the contractor to safely and properly remove any asbestos containing cutback adhesives according to guidelines set by the Resilient Floor Covering Institute publication 'Recommended Work Practices for Removal of Resilient Floor Coverings.'

Application Method:
Stir. Dilute as needed according to label instructions and installation guidelines. Apply to substrate using 3/8" nap roller, paintbrush or brush. Allow primer to dry completely prior to applying patches or floor covering.
