Features & Benefits
- Cures by means of a chemical reaction with atmospheric humidity, to form a flexible product which offers a high guarantee of durability over time
- Highly resistant to atmospheric agents and is also resistant to occasional chemical attack by hydrocarbon-derived products, such as benzene, kerosene and diesel fuel
- May only be used on horizontal surfaces or surfaces with a maximum slope of 2%
- Before painting over Mapeflex PU50 SL it must be fully cured. Mapei recommend using elastomeric paint such as Elastocolor Paint after treating the surface of the sealant with Colorite Performance. Always carry out preliminary tests to make sure the sealant and paint are compatible
- Supplied ready to use in 600ml aluminium soft cartridges
- Has a fluid consistency for quick application and, due to its quick-hardening characteristics (approx. 2mm every 24 hours), the surface may be put into service quickly with resulting economic advantages
- Classified F - 25 - LM, according to ISO 11600
- Complies with Euronorm EN 15651-4 (“Sealants for pedestrian walkways”) with performance rating PW-EXT-INT-CC
Recommendations & Limitations
- Do not use on dusty or flaky surfaces
- Do not use on damp surfaces
- Do not use on surfaces which are contaminated with oil, grease or form-release agents, since the bonding could be compromised
- Do not use on bituminous surfaces where the bleeding of oil may be present
