Estil Guru WS-DIN is a preformed waterproof 90° internal corner reinforcement. It’s designed to create a continuous, watertight seal where two internal surfaces meet, such as wall-to-wall or wall-to-suelo junctions.
Each pack contains two pieces.
Internal corners are one of the most vulnerable points for water ingress. While Mas Maya Coating is flexible and breathable, WS-DIN ensures complete waterproof continuity at corners, where movement and moisture concentration are highest. It helps prevent leaks, cracking, and long-term moisture damage behind the finish.
Use WS-DIN in all internal corners within waterproofed areas — bathrooms, showers, wet rooms, and pools. Install it into the fresh waterproofing layer or membrane, then continue with Mas Maya Coating once fully reinforced.
Crafted from plant extracts and limestone, Mas Maya Coating is breathable and free of VOCs, toxins and chemicals.
For all interior and exterior surfaces including floors, it can be applied directly over almost any material.
Due to its natural water resistancy, it's highly suited to bathrooms, pools and other areas in contact with water.
Scientists have shown that Mayan plaster mimics the structure of seashells giving it incredible strength and durability.
The added plant extracts give excellent elasticity, preventing cracking and ensuring compatibility with extreme temperatures and underfloor heating.
Our Coating is made from sustainable abundant materials sourced in Europe and to mimimise our carbon footprint it is sent in powdered form.
