ASCOSHIELD PU is a specially formulated liquid applied, highly permanent elastic, cold applied and cold curing, water based, crack bridging polyurethane membrane used for long-lasting waterproofing. When ASCOSHIELD PU is applied on substrate, it forms a hydrophobic, 100 % waterproofing, permanent elastic, seamless membrane without joints or leak possibilities. It can be applied on old and new structure for a long term basis.

Approx. 3.5 – 4.5 m²/kg per coat. This coverage is based on application by roller/ brush onto a smooth surface in optimum conditions. Factors like surface porosity, temperature and application method can alter consumption.
Available in 5 Kg and 20 Kg pail
9 months from production date, if stored in original, unopened packaging in places protected from moisture, sun exposure and frost.
The substrate must be clean, dry, sound and free of all contamination such as dirt, oil, grease, and coatings etc. which hinder adhesion.
Weak concrete/ mortar must be removed and surface defects such as blowholes and voids must be fully exposed. Concrete must be allowed to cure for 28 days and cement render and cement screeds must be allowed to cure for 7 days prior to the application of ASCOSHIELD PU.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/ or vacuum.
Porous Substrates: Prime with ASCOPRIME PU using by brush or roller. Allow primer to reach a touch dry film prior to apply. Extremely porous surfaces may require second coat.
ASCOSHIELD PU waterproofing membrane must be thoroughly mixed for 3 minutes in order to achieve a homogenous mix using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
Optimum performance level is reached after 24 hours of curing.
