U.V. LASTIK

Anti-UV Elastomeric Coating

Description

UV LASTIK is a water-based system consisting of an aqueous dispersion of elastic polymers, modifiers, additives, pigments and inorganic fillers.

Once fully cured, the film exhibits excellent adhesion and UV resistance, good elasticity, cold water resistance and weather resistance as well.

The product is suitable for coating under low temperature conditions.

Usage field

U.V. LASTIK is used to realize both anti-UV and waterproofing coatings for flexible substrates of different kind.

U.V. LASTIK is ideally suited for the protection of Spray Polyurethane Foam Insulation (SPF).

Packaging

18 kg containers and 1000 kg tanks

Application
 Before withdrawing the product from the container to apply it, thoroughly mix with a mechanical stirrer.

1) Old cementitious surface:

  • thoroughly clean and remove all loose particles and efflorescence;
  • seal cracks, compensate holes and depressions with RASANTE 1200 or GROVE RAPIDO;
  • apply a first light coat of U.V. LASTIK using a roller or flat brush, possibly diluted with 10÷20% by weight of water;
  • the next day, apply a generous second product finishing coat until achieving the exact amount required by the project.

2)New surface with spray applied polyurethane foam:

  • priming is not necessary before applying the product;
  • apply U.V. LASTIK, undiluted or slightly diluted with water, directly to the surface with an AIRLESS spray, fitted with a 21 nozzle at 3÷4 bar.
