TRUBUILD WTS 888 is a single-component, water-thinnable polymeric sealer developed to seal the porosity of porous building substrates while improving surface protection and finish quality. It penetrates into the substrate and helps reduce water absorption, improve appearance, and prepare surfaces for further finishing treatments. Water can be added depending on the surface porosity and required gloss level, making the product flexible for different site conditions.

This sealer is designed for use on sandstone, concrete, marble, bricks, terracotta, wood, and other porous surfaces. It can enhance the natural appearance of surfaces while helping reduce moisture ingress and lowering paint or coating consumption on absorbent substrates.

One of the key customer advantages is its easy water dilution, quick drying time, UV resistance, and broad substrate compatibility. After curing, the coating provides improved resistance against water penetration and supports longer-lasting surface performance.
