Terrace, Balcony and Wet-Damp Floor Waterproofing Products / Hybrid Polyurea
PUR 410 is a two component hybrid polyurea coating system with very fast setting, rapid curing and flexible properties. It can be applied as an economic waterproofing and coating alternative to pure polyurea products. It is applied at high pressure with heated multi-component spraying equipment.
Fields of Application
- General waterproofing under ceramic, screed concrete, marble and other floor coverings.
- Suitable used on light traffic areas such as roofs, terrace, walkways and public areas.
- Waterproofing of ground concrete and load bearing walls.
- Play grounds and decorative applications.
- On thermal insulation products for waterproofing (polyurethane foam, EPS, XPS etc.)
Features and Benefits
- Fast reactivity and fast curing.
- Seamless coating.
- 100% solid.
- VOC and odor free.
- No solvent content.
- Very good tensile and structural strength.
- Excellent adhesion on concrete, steel, aluminum, plastics, fibers, wood, foam etc.
- Excellent flexibility.
- Excellent crack bridging properties.
- Variable application thickness possible.
Preparation of Substrate
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. Weak concrete must be removed and surface defects such as voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface leveling must be carried out using appropriate products. Optimum surface temperature is 5-30°C, air temperature is 20-30°C and relative air humidity is 25-50%. EPOX PR 100 primer application is recommended for achieving good adhesion. Lightly broadcasting with quartz sand 0,3-0,8 mm is recommended because this provides higher adhesion values and extends the maximum waiting time of primer prior to the application of polyurea coating. In order to avoid the formation of blisters do not broadcast to excess. After 12-24 hours of primer application, polyurea application can be start.
SILOX surface impregnating material should be applied by using brush, roller or spray gun. It must be applied with saturation technique, coat after coat, without waiting for the former coat to dry up and at least two coats. Topcoats must be applied on the SILOX after 24 hours.
