How to Achieve the Best Protection
A long-lasting finish always begins with proper preparation.
First, ensure the substrate is stable, smooth and clean. Any imperfections deeper than 3 mm should be levelled with Mas Maya Prep, and in wet areas an intact waterproof membrane must already be present.
Next, apply Mas Maya Primer (or Mas Maya Pool Primer for pools and permanently wet areas), followed by the appropriate Mas Maya Coating system. Depending on the substrate, Mas Maya Mesh may be required to reinforce the coating and minimise the risk of cracking.
Once the coating has fully dried, apply two coats of Mas Maya Presealer. This step is essential—it preserves the natural colour of the coating, closes remaining pores and ensures even absorption. Applying Mas Maya Sealer directly onto the coating without Presealer will significantly darken the finish.
Finally, apply two coats of Mas Maya Sealer. For floors, furniture, commercial spaces or other high-traffic areas, two additional coats of Mas Maya Heavy-Duty Sealer can be applied for enhanced protection against wear, chemicals and abrasion.
When Is Sealing Not Necessary?
Not every installation requires sealing.
For interior walls and ceilings in dry, low-contact areas, Mas Maya Coating can be left unsealed. This allows the material to retain its maximum breathability while showcasing its natural texture and appearance.
Sealing becomes necessary whenever the surface will be exposed to moisture, frequent cleaning, staining or heavy wear.
The Bottom Line
Mas Maya Coating is naturally water-resistant and exceptionally well suited to humid environments. When combined with the correct preparation, an intact waterproof membrane where required, and the appropriate Mas Maya sealing system, it delivers a durable, beautiful finish for everything from bathrooms and kitchens to pools and exterior facades.
The key is remembering that Mas Maya Coating is the decorative finish—not the waterproof membrane itself. When each layer of the system is used as intended, you'll enjoy a natural surface that combines timeless aesthetics with long-lasting performance.
