AFM SafeCoat, Safe Seal


Sealer for toxic off-gassing of porous surfaces

Safe Seal is particularly effective at sealing in formaldehyde from processed wood such as plywood, particle board and pressed wood. Safe Seal will not block emissions of organic odors like smoke or pet smells. It's a water-based, low-gloss sealer for highly porous surfaces - mainly on surfaces that are behind the scenes, i.e. not seen or touched.

It is not designed as a topical sealer because AFM makes other sealers for that purpose. For furniture and other touchable surfaces use AFM Safecoat Hard Seal orAFM Acrylac. For flooring, or areas with high abrasion use AFM Polyureseal BP.

NOTE: this not a finish sealer - refer to AFM HardSeal, AFM Acrylac or AFM Polyureal BP. Safeseal does NOT create a hard finish but is slightly rubbery and therefore not useful as a finish.

Safe Seal was AFM Safecoat's flagship product that started the company in the mid 70's. It is one of their best selling products because it works quickly to reduce VOC emissions, usually in one application. If the odor is particularly strong, two coats may be needed. This product can be sprayed with a garden type pump sprayer, brush or roller.

If you have questions or doubts, please call us at 800-405-0222
