K11 Rigid Waterproof Mortar
Waterproofing Systems
34K11 rigid colored waterproof mortar is a polymer-modified rigid waterproof material that integrates waterproofing, decoration, and protection functions. It uses cement as a base material, incorporating special polymers and weather-resistant pigments. After curing, it forms a high-strength, high-density colored waterproof mortar layer with excellent impermeability, crack resistance, and weather resistance, making it suitable for waterproofing and decorative projects on various building surfaces.

K11 Rigid Waterproof Mortar Features
1. Rigid waterproofing with excellent seepage resistance: Based on cement hydration products, it forms a high-density, rigid structure with excellent resistance to seepage pressure and backwater seepage resistance, ensuring long-lasting and reliable waterproofing.
2. Colored decoration and integrated construction: Contains high-quality inorganic pigments, offering a variety of color options. It combines waterproofing and decorative functions, simplifying the construction process and achieving an integrated waterproofing and decorative effect.
3. Strong adhesion and good crack resistance: Polymer modification effectively enhances the bonding strength with various substrates (concrete, mortar, brick walls, etc.) and imparts good flexibility to the mortar layer, resisting the propagation of micro-cracks in the substrate.
4. Weather-resistant and chemical-resistant: It possesses excellent resistance to ultraviolet radiation, high and low temperature cycling, and chemical media such as acids, alkalis, and salts, making it suitable for complex outdoor and harsh industrial environments.
5. Easy construction and environmentally friendly: A single-component powder, it can be used immediately after mixing with water on-site. Operation is simple and construction efficiency is high. It is non-toxic, odorless, meets environmental protection requirements, and is safe to use.
Suitable for waterproofing and seepage prevention projects on building base surfaces such as concrete, mortar plaster, and brick walls, including waterproofing and decoration of exterior walls, basements, kitchens and bathrooms, water tanks, and swimming pools, especially suitable for waterproofing areas where color is a requirement.
K11 Rigid Waterproof Mortar Construction Guidelines
1. Surface cleaning: Thoroughly remove dust, oil, loose particles, and impurities from the cement substrate surface to ensure a firm, flat, and clean surface, laying a solid foundation for subsequent waterproofing construction.
2. Precise proportioning: Use a dedicated container and strictly adhere to the liquid-to-powder ratio of 1: 2.78 to measure and mix the materials, ensuring precise proportioning and stable performance of the final waterproofing layer.
3. Slurry mixing: Pour the weighed liquid into a mixing bucket and slowly add the corresponding powder while maintaining low-speed mixing. Continue mixing for 3-5 minutes to create a uniform, fine, particle-free, and lump-free waterproofing slurry.
4. Settling and curing: After mixing, allow the slurry to stand for 3-5 minutes to eliminate air bubbles. Before application, mix again at low speed for 1 minute to restore the slurry to a uniform state.
5. Surface wetting: Before application, evenly spray water onto the cleaned, dry substrate to moisten it, keeping the surface damp but without standing water, which promotes strong adhesion of the waterproofing layer.
6. Waterproof coating: Apply the first coat of slurry evenly with a roller or brush, ensuring no areas are missed, after it is surface dry and no longer sticky (usually about 4-8 hours), apply the second coat vertically in a crisscross pattern to ensure the total thickness meets the construction requirements.
