Acts as a barrier to moisture on structural concrete
Water-based and non-flammable
Product Info
X4 (Ready-to-use) is a clear, water repellant sealant for cement and concrete based facades/claddings, surfaces, structural and building materials. It prevents freeze/thaw expansion, moisture absorption, deterioration and damage.
Uses
Exterior surfaces and where preventing moisture absorption is important
Surfaces
X4 is an excellent water repellent for many absorbent mineral substrates, such as bricks, sand-lime brick, natural sandstone and mineral plasters. It is not suitable for less absorbent, dense natural stone, especially limestone, marble and reinforced concrete for bridges and roads. Owing to its aqueous consistency and storage stability, X4 is ideal for in-plant impregnation of building materials made of clay, aerated concrete, sand-lime brick, fibrous cement, mineral fibers and lightweight aggregate. X4 may also serve as a water repellent primer for emulsion paints and plasters, silicone resin emulsion paints and silicone resin plasters.
Safety
Consult SDS for details
Instructions
X4 is best applied by sprayer to the point of complete saturation to obtain an even coverage and penetration. After the first coat is applied and the surface has absorbed by not yet completely dried, a second application applied perpendicular to the first coat is recommended.
Coverage Rate
Each gallon is expected to cover an average of 175-250 ft2 per coat of X4. Coverage may vary due to surface texture, porosity, age and application method. This does not include loss from over-spray or over-use.
