MASTIC TECHNONICOL No.33
Spray-applied water-based roofing and waterproofing polymer-bitumen mastic
Spray-applied roofing and waterproofing bitumen mastic TECHNONICOL No.33 presents a mix of an aqueous emulsion of bitumen, special polymers and latex additives. It has an outstanding elasticity, heat endurance and strength properties. The mastic has a neutral smell, so it is perfectly suited for indoor works. Spray application of the mastic can significantly reduce the time needed for installation of waterproofing layer.
Mastic TECHNONICOL No.33 is used for:
- indoor waterproofing (bathrooms, balconies, etc.);
- installation of mastic roofs and repair of old roofs;
- waterproofing of underground structures (foundations, basements, piles, etc.).
The mastic is spray applied to a surface together with coagulant solution (supplied with the product) by a dual-channel airless spraying device.
The product should be stored in a dry place protected from direct sunlight at temperatures from +5°C to +30°C. Shelf life – 6 months.
