Q: The colour of Enviro Clad that I have chosen is close, but not the exact shade that I need. Can I get it tinted?
A: Yes. Enviro Clad can be tinted up to 10% at a maximum.

Q: What is the difference between the water-based and solvent based polyurethane?
A: The 2 products have slightly variant applications. The water and solvent base waterproof membranes also have respective primers and cleaning agents as well. Both are completely applicable to internal waterproofing.

Q: I have used the Enviro 700PUR but my tiler is concerned the surface is too smooth to tile to, what can I do?
A: Because of the lowered viscosity of the solvent based polyurethane, it 09ds to dry smoother than the water base. Although comprehensive testing has been undertaken to ensure sufficient adhesion occurs between the membrane and Enviro GTA, a fine layer of sand can be cast into the 700 to give added tacticity for the tile glue to set around.

Q: How long can I wait before the UV protection needs to be applied to my non-UV stable membrane.
A: It is important that non-UV stable membranes are not exposed to sunlight for too long. It is recommended by Envirosystems to cover the membrane within a week of application and no longer than 2 weeks.

Q: Do I need to use fabric with my membrane?
A: This is product specific. The technology Enviro employs means a lot of our membranes no no longer require fabric reinforcement. A few of our older technologies we still recommend the use of fabric reinforcement.
