Can You Make Gypsum Plaster Waterproof?
For years, gypsum-based materials like plaster and concrete have been limited by their porosity. Homeowners, designers, and industries alike have asked the same question: "Can you make gypsum plaster waterproof?" At Bramstone, we’re proud to say that the answer is yes. Our innovation didn’t just overcome this challenge - it redefined what gypsum plaster can achieve.
The Challenge of Waterproofing Gypsum
Gypsum, by nature, is highly porous. Like a sponge, it absorbs water, without our unique Bramstone seal it is unsuitable for applications where exposure to moisture is inevitable. This has long been a limitation for designers and manufacturers working with this versatile plaster material since the 17th century.
When we first started experimenting with waterproofing our gypsum based casting compound, the problem seemed deceptively simple. Initially, our test pieces would appear fine, giving us hope that we had cracked the code. But within 20 minutes, darker dots would start forming on the surface - a clear sign that water was being absorbed. These dots often appeared near small pores or tiny imperfections, emphasising the challenge of creating a flawless seal.
If the material couldn’t withstand water for an hour, we deemed it a failure. And there were many, many failures.
The Breakthrough: A Multi-Faceted Approach
Achieving 100% waterproofing for gypsum was no simple feat. After months of trial and error, countless tests, and consultation with experts, we realised that the solution required more than just a single product or technique. It became a multi-faceted process involving different layers of specialised products that worked together to create a seamless, water-resistant barrier.
This was no ordinary sealant job. Each layer had to serve a specific purpose, from filling microscopic pores to creating a smooth, impenetrable outer surface. The process took time, patience, and countless iterations. But when we finally succeeded, it felt nothing short of miraculous.
The day we filled a basin with water and watched it remain impervious for over two days was one we’ll never forget. For many, a waterproof basin might seem elementary, almost a given. But for us, attempting to emulate the properties of ceramics without the use of a kiln was a monumental achievement.
Why Waterproofing Gypsum Matters
Our breakthrough opens up a world of possibilities for gypsum-based materials:
-
Bathroom Fixtures: Durable, water-resistant basins, vanities, and tiles.
-
Commercial Interiors: Seamless gypsum walls and decor that can withstand high-moisture environments.
-
Custom Art Pieces: Sculptures and designs that maintain their integrity, even in damp conditions.
These applications are just the beginning. By solving the waterproofing challenge, we’ve transformed gypsum from a limited material into a versatile medium ready to meet the demands of modern design and construction.
