Awazel Liquid Polyurethane PU 250 white, 25kg

The advantages of AWAZEL PU 250 as a waterproofing membrane are
- Simple application (roller or airless spray
- Forms seamless membrane without joints
- Resistant to water, frost, and root penetration
- Crack-bridging up to 2mm, even at -10oC
- Provides water vapor permeability, so the surface can breathe
- Provides excellent thermal resistant, it never turns soft
- Provides excellent weather and UV resistance
- Waterproofs old bitumen-asphalt felts by covering them, without the need to remove them prior to application
- Provides high sun reflectivity, contributing to thermo-insulation
- Maintains its mechanical properties over a temperature span of -40oC to +90oC
- Provides excellent adhesion to almost any type of surface
- The waterproofed surface can be used for domestic and public pedestrian and vehicular traffic
- Resistant to detergents, oils, seawater, and domestic chemicals
- Even if the membrane gets mechanically damaged, it can be easily repaired locally within minutes.

The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane.
Maximum moisture content should not exceed 5%. 
Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. 
New concrete structures need to dry for at least 28 days. 
Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. 
Possible surface irregularities need to be smoothed. 
Any loose surface pieces and grinding dust need to be thoroughly removed. 
After surface preparation, stir well before using. 
Pour the Awazel PU 250 onto the surface and lay it out by roller or brush, until all surface is covered. 
You can use airless spray allowing a considerable saving of manpower. 
After 12-18 hours (not later than 48 hours) apply another layer of the Awazel PU 250.
 For demanding applications, apply a third layer of the Awazel PU 250.

What surfaces can AWAZEL PU 250 be used on
AWAZEL PU 250 can be used on various surfaces including roofs, balconies, terraces, wet areas (under tile) in bathrooms and kitchens, pedestrian and vehicular traffic decks, green roofs, flower beds, planter boxes, old bitumen felts, asphalt felts, EPDM and PVC membranes, old acrylic coatings, and concrete constructions like bridge-decks, tunnels, stadium stands, and car parks.

How should the surface be prepared before applying the membrane
The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%. Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. New concrete structures need to dry for at least 28 days. Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothed. Any loose surface pieces and grinding dust need to be thoroughly removed. It is important to note that the surface should not be washed with water.
