- Recommendation for Use
- For bonding preferably use our two-component adhesives (eg PELPREN PL6) or onecomponent silane adhesives such as ADHESIVE WB MONO MS / LE or WB MONO MS
- Always use adequate personal protection systems
- Preparation of the Support
Always check the humidity of the substrate with suitable tools. The substrate to be treated must be compact and free of detaching parts and compliant with DIN 18356. Any surface defects, such as cracks or cracks, must be treated by mixing fine sand (not marine) with PRIMER WB PU until a homogeneous mortar is obtained. Before applying, make sure there is an adequate vapor barrier.
- Application
Ambient and mix the product before use. Always check the compactness and humidity of the screed (max 4 - 5%). Apply the first coat of PRIMER WB PU by roller or brush. Leave to dry in a ventilated area for 45 - 55 minutes in suitable environmental conditions +15 ° C - 25 ° C and 50 - 70% RH (different conditions may lead to less than excellent results or a variation in drying times). If necessary, apply the second coat of PRIMER WB PU within 12 hours and in the case of applying 1 leveler, spread some fine (0.1 - 0.3 mm) and dry (non marine) quartz sand on the last primer coat. . Subsequently (after about 2 hours) remove the excess sand before bonding which must be carried out within 24 hours. Always use adequate individual protection systems.
