PMMA System

🏠 How PMMA Protects Your Home From Moisture

PMMA (polymethyl methacrylate) is a special liquid-applied waterproofing material. Once installed, it turns into a seamless, durable, and water-resistant shield over your surface. Here’s why it works so well:

1. Seamless Barrier

   • PMMA is applied as a liquid and cures into a single continuous layer.

   • Unlike tiles, torch-on membranes, or sheet systems, there are no overlaps, joints, or seams where water can find its way in.

   
   

2. Water-Repellent Nature

   • PMMA is naturally hydrophobic, meaning it repels water instead of absorbing it.

   • This reduces the chance of water seeping into concrete, tiles, or other building materials below.

   
   

3. Low Moisture Permeability

   • The material structure is very dense, making it hard for water vapor to penetrate through.

   • This is especially important for areas like balconies and roofs, where constant exposure to rain and humidity can otherwise cause slow leaks.

   
   

4. Strong Adhesion to Surfaces

   • PMMA bonds tightly to concrete, screed, tiles, and even metals.

   • This prevents water from creeping underneath the waterproofing layer (a common issue with peeling membranes).

   
   

5. Durability Against Weather

   • Sunlight, UV rays, heat, and rain won’t easily break down PMMA.

   • Unlike some coatings that become brittle or crack, PMMA stays flexible and strong for years.

   
   

6. Quick Curing & Repairs

   • PMMA cures fast, even in colder weather, so surfaces are protected quickly.

   • If future repairs are needed, new PMMA layers fuse seamlessly with the old ones, without weak joins.

✅ In simple terms: PMMA is like giving your roof, balcony, or wet area a watertight shield that’s flexible, durable, and long-lasting. It stops leaks, protects the structure beneath, and saves you from costly water damage.
