Why Regular Clay Plaster Isn’t Suitable for Showers
Conventional clay plasters have amazing qualities — breathability, eco-friendliness, and texture — but they come with a major downside in wet environments:
They absorb water.
They can swell or crack.
They require constant maintenance.
The Waterproofing Breakthrough: Clay® with Hydro+
To use clay in wet zones, you need something more advanced — and that’s exactly what Clay® by Topcret delivers.
Hydro+ is an integrated system that makes Clay® waterproof before sealers. That means:
- Fully safe for showers and splash zones.
- No need to compromise on aesthetics.✅ Faster application, fewer layers, less risk.✅ Consistent, long-term performance.
Clay® combines the visual appeal of raw clay with the durability and moisture resistance usually reserved for microcement or tiles.

What our clients say
- Topcret helped me doing a repair on my existing floor, and went the distance to get a good result. I would definitely use them againGillian D.★★★★★ (opens in a new tab)
- Jack and the team at Topcret were top-draw. We're beyond pleased with the finished look, but also very impressed with the experience. From our 1st meeting to the aftercare, Topcret were nothing but professional, knowledgable, friendly and flexible. Highly recommend.Sam S.★★★★★ (opens in a new tab)
- Topcret and Juan in particular went above and beyond. Juan worked long days to finish the project as soon as possible, and used his technical knowledge and expertise to problem-solve some of the issues we had with previous tradesmen's mistakes. So happy Topcret could match the paint colour we wanted and that the result is more of an even finish than the typical microcement mix of shades (which they can do as well - we just didn't want that look). Delighted with the result and would definitely use them again. Thank you so much!Isabel D.★★★★★ (opens in a new tab)
