Description
PU FLEX 2000 UV PROTECT is an elastomeric 100% aliphatic polyurethane TOPCOAT, UV stable with excellent resistance to moisture and stagnant water. It keeps its colour unchanged over time without turning yellow or chalking. Intended as a final coating in common polyurethane waterproofing systems for exposed roofs as well as common building surfaces.
ADVANTAGES
- Exceptional resistance to UV radiation
- Resistance to temperature: -40oC to +90oC
- Colour stability, without chalking, even after long exposure to UV radiation
- Highly elastic - ability to cover small cracks
- Excellent compatibility with liquid applied polyurethane waterproofing membranes
- Excellent adhesion to porous surfaces and even without the use of primer
- Increases wear and abrasion resistance of the waterproofing system
- High resistance to stagnant water and many chemicals
- Resistant to light pedestrian and vehicle traffic
APPLICATIONS
PU FLEX 2000 UV PROTECT is suitable for repairing, refining and revitalizing polyurethane roofing membranes, offering a stronger coating with exceptional strength and excellent UV resistance for old and new applications. It is also suitable for terraces, rooftops, pedestrian corridors, open parking and many other areas. Recommended for coating polyurethane foam insulation systems.
PU FLEX 2000 UV PROTECT is recommended for use as a final coating over PU FLEX 1000.

Instructions for use
Substrate preparation
Careful surface preparation is very important for optimum finish and durability.
Application surfaces must be free from dust, grease, loose residues, and moisture that may affect adhesion. It should not be applied to wet surfaces or when rain is expected.
Application
- Stir well before use.
- Pour the PU FLEX 2000 onto the surface and spread it using a roller or brush, until the entire surface is covered.
- You can use an airless spray, allowing a considerable saving of manpower.
- After 4 – 24 hours and not more than 48 hours, apply a second layer of PU FLEX 2000 if needed.
- PU FLEX 2000 can be diluted up to 10% with DIL X 100 solvent for easier application.
- After opening the container, use all the product. Opened containers cannot be restored to be used another time.
Attention
For best results, the temperature during coating and curing should be between 5oC and 35oC.
