Description
SikaTile-111 Rapid Proof is a rapid drying, water-based Class III flexible waterproofing membrane designed for wet areas, balconies and other under tile and stone waterproofing applications. Being ultra-fast drying, it’s ready for tiling just 2-3 hours after the final coat, a genuine advantage on jobs where waiting a full day or more for a membrane to cure would hold up the entire tiling schedule.
Its unique colour-changing technology gives installers a clear, visual way to confirm each coat has actually dried before moving on, rather than relying purely on elapsed time under variable site conditions. Combined with a superior film build that achieves the required dry film thickness more easily than traditional liquid-applied membranes, and independent third-party testing confirming compliance with both AS4654 and AS4858, it’s built for genuine, verifiable wet-area performance rather than just fast turnaround.
Being water-based and solvent free with low VOC, it suits both residential and commercial applications where indoor air quality during installation matters, and its micro-fibre reinforcement gives it Class III flexible performance greater than 300%, accommodating real substrate movement without cracking. It’s not designed for submerged applications like pools and spas, and shouldn’t be left exposed longer than 30 days before tile or stone covering goes down.

How to Apply
- Prime as required — SikaTile 010 Secure Prime for porous, SikaTile 015 Prep n Prime for non-porous substrates.
- Stir before use — mix the membrane with a paddle.
- Apply the first coat — at 0.75L/m², waiting 2-2.5 hours before the next coat.
- Apply the second coat — to reach a 1.00mm total dry film thickness.
- Allow to dry before tiling — 2-3 hours after the final coat.
Important Notes
- Not designed for exposed UV-stable application or submerged applications such as pools and spas.
- Do not apply if rain or bad weather is imminent.
- Do not allow to freeze; store in dry, cool conditions out of direct sunlight.
