Seal-Once Multisurface Waterproofer

SE-101 – One US Gallon/3.79L | Clear
– Five US Gallons/18.92L | Clear

Seal-Once™ Advanced Multi-Surface Waterproofer is a concentrated, waterbased formula designed for waterproofing wood, composite wood, concrete and masonry. Eco-friendly Seal-Once is designed to be diluted with clean water at a 1:1 ratio for easy application.

Allow pressure-treated wood to age up to 3 to 6 months before applying Seal-Once. Not recommended for basement floors and walls subject to hydrostatic pressure (active leaks or continually damp areas).

For best results, all surfaces should be cleaned before sealing for best penetration and performance of a coating. To remove algae, grime, mildew, effloresence etc., we recommend Seal-Once™ All Wood Cleaner for wood and Seal-Once™ Concrete Masonry Cleaner for concrete. Pressure washing is recommended.
