FAQ
What is Trubuild Water Repellent WRP-777?
Trubuild Water Repellent WRP-777 is a high-performance, solvent-based silane water repellent designed for the protection and waterproofing of exterior concrete and masonry surfaces. It penetrates deep into the substrate and forms a hydrophobic barrier.
How does Trubuild Water Repellent WRP-777 protect concrete surfaces?
The silane active ingredient in Trubuild Water Repellent WRP-777 chemically reacts with the concrete substrate and lines the pores with a water-repellent coating. This prevents the ingress of water, chloride ions, and other dissolved salts that can cause deterioration.
What are the key features of Trubuild Water Repellent WRP-777?
Trubuild Water Repellent WRP-777 is a deep-penetrating, non-film forming, and breathable water repellent. It provides excellent resistance to water, freeze-thaw cycles, chloride-induced corrosion, and efflorescence, while maintaining the natural appearance of the substrate.
What surfaces can Trubuild Water Repellent WRP-777 be applied on?
Trubuild Water Repellent WRP-777 is suitable for application on a wide range of exterior concrete and masonry substrates, including precast concrete, cast-in-place concrete, concrete bridges and highways, parking decks, brick masonry, natural stone, and cement-based stucco.
How is Trubuild Water Repellent WRP-777 applied?
Trubuild Water Repellent WRP-777 can be applied by low-pressure spray, brush, or roller on clean, dry concrete surfaces. It is supplied ready to use and should be applied in a single, saturating coat. On very porous substrates, two “wet-on-wet” coats may be required.
What is the coverage rate of Trubuild Water Repellent WRP-777?
The coverage rate of Trubuild Water Repellent WRP-777 depends on the porosity and texture of the substrate. It typically covers 100-150 sq.ft./L on dense, smooth concrete and 50-100 sq.ft./L on porous, textured surfaces like exposed aggregate or concrete block.
How long does Trubuild Water Repellent WRP-777 take to dry?
Trubuild Water Repellent WRP-777 dries to touch within 2-3 hours and develops its water-repellent properties within 24 hours under normal conditions. However, the complete curing and maximum effectiveness may take 3-5 days or more, depending on the substrate and environmental conditions.
Does Trubuild Water Repellent WRP-777 change the appearance of the concrete surface?
Trubuild Water Repellent WRP-777 does not form a visible film or significantly alter the color or texture of the concrete surface. It may slightly darken some light-colored substrates initially, but this effect is usually temporary and minimal.
How long does the protection from Trubuild Water Repellent WRP-777 last?
When applied as per the recommended procedure on properly prepared concrete surfaces, Trubuild Water Repellent WRP-777 can provide effective water repellency and protection against chloride ingress for 7-10 years or more, depending on the exposure conditions and substrate quality.
Is Trubuild Water Repellent WRP-777 VOC compliant?
Trubuild Water Repellent WRP-777 is a low VOC formulation that complies with most national and regional regulations on volatile organic compounds. However, always check the local VOC requirements and use appropriate safety precautions during handling and application.
