Seal-Once Concrete Waterproofer
Invented by a polymer chemist, long lasting Seal-Once™ waterproofs against water, mold, mildew and UV damage for up to 10 years on vertical surfaces and six years on horizontal surfaces. The water-based, non-flammable, odorless formula penetrates the concrete surface and forms a clear flexible film that is breathable and impervious to salts and chlorides. Seal-Once also exceeds current and future eco-requirements, with no VOC’s, toxins or irritants. It is 100% safe for use around people, pets and plants.
Comes in 5 gallon buckets. Covers approximately 750 sq ft (150 per gallon). Choose from 3 different tints or clear sealer. Clear sealer does not have UV protection.
