Bath-PRO Advance 2K
Bath-PRO Advance 2K is a two-component, cementitious waterproofing coating system formulated with a blend of high-grade cement, graded fillers, performance-enhancing additives and an acrylic polymer dispersion. The system forms a durable and flexible coating with strong adhesion to concrete and masonry surfaces, making it suitable for underlay waterproofing, roofs and other horizontal substrates. A two-component acrylic polymer-modified waterproofing membrane. When mixed properly, it forms an easy-to-apply brush or trowel coating with excellent adhesion, toughness and durability. Suitable for concrete, screed, plaster and masonry surfaces.
- Superior chemical bonding
- Higher abrasion resistance
- Well-optimised polymer-to-cement ratio for improved flexibility and adhesion
- High flexural/tensile strength to control cracking
- Resists extreme hydrostatic pressure
- Easy to apply and cost-effective

How to apply
- 01
Prepare
- Ensure the surface is clean, dry, sound and free from dust, oil, grease and loose particles.
- Repair cracks and joints before application.
- 02
Mix
- Mixing ratio: powder 4.5 kg + liquid 1.5 kg = 6 kg bucket.
- Add liquid and clean water as required, then slowly add powder while mixing.
- Mix for 2–4 minutes until a smooth, lump-free consistency is achieved.
- 03
Apply
- Apply evenly with a brush or stiff-bristle brush, at 100–150 mm width for joints and required areas.
- Apply 2 coats of approximately 1 mm each; let the first coat dry before the second.
- Protect the coating from water until fully cured.
Safety precautions
- Non-toxic but alkaline in nature: wear gloves and goggles, and a dust mask while handling the powder.
- Wash splashes on skin or eyes off with clean water; seek medical advice if irritation persists.
Important notes
- Store in a cool, dry, well-ventilated area away from direct sunlight and extreme temperatures.
- Keep out of reach of children; keep the container tightly sealed when not in use.
