FAQ
What is Trubuild Walltect Basecoat?
Trubuild Walltect Basecoat is a high-build, acrylic-based waterproof base coat designed for use as a preparatory layer on exterior masonry walls prior to the application of Trubuild Walltect Top Coat.
Why is a base coat like Trubuild Walltect Basecoat used in exterior waterproofing systems?
A base coat like Trubuild Walltect Basecoat helps to level the wall surface, fills minor imperfections, provides additional waterproofing, and improves the adhesion and durability of the subsequent top coat in an exterior wall waterproofing system.
What are the key features of Trubuild Walltect Basecoat?
Trubuild Walltect Basecoat is a high-solid, flexible, and crack-resistant base coat. It offers excellent adhesion, water resistance, and compatibility with a variety of exterior wall substrates and top coats.
How does Trubuild Walltect Basecoat contribute to waterproofing?
The high film build and low water permeability of Trubuild Walltect Basecoat helps to seal the wall surface, fill pores and minor cracks, and provide an additional layer of water resistance beneath the top coat.
What is the recommended application thickness for Trubuild Walltect Basecoat?
Trubuild Walltect Basecoat should be applied at a wet film thickness of 1000-1200 microns (1-1.2 mm) in two or more coats by brush or roller to achieve an adequate dry film thickness for optimal performance.
How long should Trubuild Walltect Basecoat be allowed to dry before top coating?
Under normal conditions, Trubuild Walltect Basecoat dries to touch in 30 minutes and can be recoated in 4-6 hours. However, allow it to dry completely for at least 12 hours before applying the top coat.
Can Trubuild Walltect Basecoat be used without a top coat?
While Trubuild Walltect Basecoat provides some degree of waterproofing, it is not designed to be a standalone finish. Always overcoat it with a compatible top coat like Trubuild Walltect Top Coat for complete protection and durability.
What surface preparation is needed before applying Trubuild Walltect Basecoat?
The wall surface should be clean, dry, and free from loose particles, dust, grease, or any contaminants. Repair any cracks, gaps, or damages. Remove any efflorescence, laitance, or previous coatings that are loose or flaking.
Can Trubuild Walltect Basecoat be applied on damp surfaces?
No, Trubuild Walltect Basecoat should not be applied on damp or wet surfaces as it can affect the adhesion and film formation. Allow the surface to dry completely before application. Moisture content should be below 12%.
Is Trubuild Walltect Basecoat suitable for interior use?
While Trubuild Walltect Basecoat is primarily designed for exterior wall waterproofing systems, it can also be used on interior basement or foundation walls that are prone to water seepage, before applying a suitable topcoat or finish.
