Vetoproof AZL

Single-component, flexible hybrid polyurethan roof waterproofing membrane.

Vetoproof AZL is a single component, cold liquid applied waterproofing and protective coating, based on a hybrid polyurethane technology. Vetoproof AZL is flexible, durable, and UV-resistant. The product is white in color with a high solar reflective index (SRI) that ensures better thermal roof insulation. It is a new technology towards Green Revolution in PU Based Products.

Uses

  • Waterproofing of wet areas like bathrooms, toilets, public showers and kitchens.
  • Waterproofing of roofs, terraces, balconies, domes, aluminum sandwich panels and corrugated sheets. 
  • Waterproofing exposed roofs of concrete, metal, cement, and gypsum board surfaces in both new construction and refurbishment projects.

Advantages

  • Easy to use.
  • Low VOC.
  • Excellent resistance to water and vapour.
  • High resistance against chlorides, sulphates, bacteria, oil and common fuels.
  • Exceptional sun rays reflection which reduces indoor temperatures and electricity consumption.
  • Highly elastic and crack-bridging.
  • It can be applied over sloped roofs.
  • Dirt-pickup resistance.
  • Resists impact damage and foot traffic.
  • Excellent UV resistance, weatherability & color retention properties.
  • Excellent to refurbish existing roofs without replacing them.
  • Environmentally friendly.

Usage Instructions

All surfaces should be dry and free from contamination, such as oil, grease, loose particles, decayed matter, moss algal growth, laitance, and all traces of mold release oils and curing compounds. This is best achieved by lightly grit-blasting the surface. Where moss, algae, or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with a Saveto repair system.

Note: *Concrete substrates should be at least 14 days old.

Vetoproof AZL does not require priming and can directly be applied onto the concrete surface. In case of highly porous surface, a priming coat is recommended to seal the pores and stabilize the surface. The primer coat can be produced on site by diluting Vetoproof AZL 1:1 with water. Apply one coat and allow to completely dry.

Vetoproof AZL is a single component product but mix the contents of the pail thoroughly prior to application to remove any sediment. A slow speed drill and suitable paddle mixer shall be used to avoid the formation of air bubbles.

The coating can be applied with a brush, roller or airless spray machine and shall be applied in a minimum of 2 coats. The 1st coat shall be allowed to dry completely for 4 - 12 hours depending on the ambient temperature. before the 2nd coat is applied. The 2nd coat shall be applied cross wise to the first coat. The coating will achieve its full strength after a curing period of 7 days.

Apply the second coat perpendicular to the first coat.

It is recommended for heavy pedestrian traffic to use polyester fleece reinforcement, embedded firmly in the second coat while wet, and a third coat should be applied..

Remove Vetoproof AZL product from tools, equipment, and mixers with clean water before the initial set. Cured material can only be removed mechanically.
