ONE-COMPONENT, HIGH-ELASTIC POLYURETHANE WATERPROOFING MEMBRANE

1- Surface Preparation:
Surfaces must be dry and free from oil, dust, dirt, grease and loosing materials. The substrate should be firm, in case of gaps and cracks fill with suitable polysulphide sealant and ensure the surface is level.

2- Substrate Priming:
For most situations, the substrate should be primed with SpECtite PUFlex Primer. SpECtite PUFlex can be applied as soon as the primer becomes tack-free.

3- Application:
Stir well before use. Do not apply if rain is expected within 24 hours. Apply the material using brush or roller. A second coat is applied at right angle to the first coat, after the first coat is dry. It is recommended to apply two coats of SpECtite PUFlex to get a thickness of 1mm. Multiple coats can be applied to achieve higher thickness. Embed fiber mesh around all corner joints, fillets, pipe penetration, pipes, over cracks, drains and where substantial movement is anticipated. Lay fibre mesh in the wet first coat before the application of subsequent coats.

4- Curing:
It requires 24 hours to dry in between 2 coats and 48 hours curing is adequate for foot traffic. Low temperature and high humidity will slow down the curing process. 7 days are required for full cure. In case of expected rains, do not apply SpECtite PUFlex. Ensure curing is complete before laying thermal insulation board mechanical protection and other coverings.

5- Application Temperature Range:
5°C to 50°C
