POLYURETHANE WATERPROOFING LIQUID MATERIAL
PROPERTIES : BITUFLEX PU is one component polyurethane liquid waterproofing membrane based on elastomeric , hydrophobic polyurethane resins. The film that is formed is elastic, ,vapour permeable and uniform without seams . It has excellent mechanical, chemical, thermal, UV and weather resistance properties
USAGE BITUFLEX PU can be applied to many substrates such as concrete ,stone, wood , any type of waterproofing membrane ,etc.
BITUFLEX PU is the ideal product for waterproofing and protection of : surfaces with stagnant water ,roofs ,basements ,tanks, terraces and balconies , bathrooms or kitchens (under tile) construction works such as parking decks ,bridge decks ,tunnels ,irrigation channels, etc.
APPLICATION The surface must be smooth ,clean and dry, free from dust, oils and grease .A moisture content of less than 5% is generally recommended for concrete surfaces, Rainy weather should be avoided.

BITUFLEX PU can be applied without the use of a primer. However the use of primer BITUFLEX PU PRIMER is recommended in order to improve the mechanical properties of the surface of the concrete.
The first layer is applied not earlier than 1 hour and not later than 24 h after priming with BITUFLEX PU PRIMER . The second layer should be applied crosswise after 3-24 hours dependant upon the weather conditions. For application by airless spray it is suggested to dilute the product with xylene up to 10%..
