ACTFLEX 400 Clear is a game-changing transparent waterproofing coating that lets you stop leaks without ripping up tiles or damaging existing finishes. Formulated with advanced synthetic rubber latex, it creates a UV-stable, flexible barrier that seals and protects tiled and masonry surfaces — all while maintaining their original look.

Unlike traditional membranes, ACTFLEX 400 Clear forms a clear, durable film that resists cracking, sunlight, and weathering. It’s perfect for leaking balconies, bathrooms, and outdoor tiles where removing the surface isn’t an option. Once cured, it delivers a seamless, semi-gloss finish that’s tough enough for foot traffic and exposure to the elements.

Whether you’re a tradesperson saving a client’s balcony or a homeowner dealing with a costly leak, ACTFLEX 400 Clear is the go-to rescue product that restores waterproofing performance quickly, cleanly, and cost-effectively.
