What are the main product features of K11 Flexible Waterproof Coating?
What are the main product features of K11 Flexible Waterproof Coating?
Key features include: excellent flexibility and crack-bridging ability (typically up to 1–2 mm); can be applied on damp substrates; strong adhesion and penetration into capillary pores; high waterproofing performance with good weather and aging resistance; vapor permeable (breathable); non-toxic and eco-friendly; suitable for areas with slight movement; tiles can often be bonded directly after drying.
What is the difference between K11 Flexible and K11 Universal Waterproof Coating?
What is the difference between K11 Flexible and K11 Universal Waterproof Coating?
K11 Flexible has higher elasticity and better crack-bridging performance, making it ideal for areas with slight vibration, movement or micro-cracks (e.g., roofs, balconies, pipe surroundings, expansion joints). K11 Universal is more rigid/semi-rigid and better suited for stable structures without significant movement.
Where can K11 Flexible Waterproof Coating be used?
Where can K11 Flexible Waterproof Coating be used?
It is suitable for indoor and outdoor concrete, brick and masonry surfaces, including bathrooms, kitchens, balconies, roofs, basements, swimming pools, drinking water pools, tunnels, parking lots, pipe surroundings, expansion joints and areas prone to slight movement or cracks.
Is K11 Flexible Waterproof Coating non-toxic and suitable for pools?
Is K11 Flexible Waterproof Coating non-toxic and suitable for pools?
Yes. It is non-toxic and environmentally friendly, making it suitable for swimming pools, drinking water reservoirs and fish ponds when fully cured.
How do I prepare the surface for K11 Flexible Waterproof Coating?
How do I prepare the surface for K11 Flexible Waterproof Coating?
Ensure the substrate is firm, flat, clean and free of dust, oil, loose materials and contaminants. Repair holes, cracks and defects with cement mortar. Form rounded corners at internal/external angles and reinforce critical joints (pipes, corners) with non-woven fabric or fiberglass mesh. Pre-wet the surface thoroughly but leave no standing water.
How do I mix and apply K11 Flexible Waterproof Coating?
How do I mix and apply K11 Flexible Waterproof Coating?
Pour the liquid into a clean container, slowly add the powder while mixing with a low-speed mechanical mixer until a smooth, lump-free paste is obtained (typical ratio follows product instructions, e.g. powder:liquid around 11.6:8.4 or similar). Let it rest briefly, then remix. Apply with brush or roller in 2 or more coats, each coat perpendicular to the previous one. Keep intermittent stirring during use. Apply each coat at ≤0.8–1 mm thickness.
How many coats and what thickness are recommended for K11 Flexible Waterproof Coating?
How many coats and what thickness are recommended for K11 Flexible Waterproof Coating?
For damp-proofing: usually 1 coat (approx. 0.6–0.8 mm). For waterproofing: at least 2 coats with total dry film thickness around 1.2–2.0 mm (typical consumption 2.0–2.5 kg/m² for two coats on flat surfaces). Reinforce details as needed.
What are the important construction precautions for K11 Flexible Waterproof Coating?
What are the important construction precautions for K11 Flexible Waterproof Coating?
Apply only at temperatures between 5°C and 40°C. Avoid rain, high humidity without ventilation, direct strong sunlight or freezing conditions. Use the mixed material within the pot life (usually 30–120 minutes); never add water to material that has started to set. Protect the fresh coating from foot traffic and damage until fully cured (typically 24–48 hours or longer). Ensure good ventilation if the area is enclosed.
Can I walk on or tile over K11 Flexible Waterproof Coating soon after application?
Can I walk on or tile over K11 Flexible Waterproof Coating soon after application?
Light foot traffic is usually possible after surface drying (about 24 hours), but full curing may take 24–72 hours or more depending on conditions. Tiling or other covering layers should only be done after the waterproof layer is fully dry and cured. Protect the membrane from sharp objects and heavy loads during construction.
Is K11 Flexible Waterproof Coating suitable for bathrooms and roofs with possible movement?
Is K11 Flexible Waterproof Coating suitable for bathrooms and roofs with possible movement?
Yes. Its high flexibility makes it especially suitable for bathrooms, balconies, roofs and other areas that may experience slight structural movement, temperature changes or micro-cracks. Reinforce corners and pipe penetrations for best results.
How long does K11 Flexible Waterproof Coating last and does it need a protective layer?
How long does K11 Flexible Waterproof Coating last and does it need a protective layer?
When properly applied and protected, it offers long-term waterproofing performance with good durability and weather resistance. In many cases, tiles or a protective screed can be applied directly after curing; in high-abrasion or exposed areas, an additional protective layer is recommended for extended service life.
