SpiderWeb II Uncoupling Mat by Custom Building Products
Custom Building Products offers the SpiderWeb™ II Uncoupling Mat, which is a waterproof, vapor-proof membrane for crack-isolation in most tile and stone installations. It is suitable for all types of tile, can be applied over challenging substrates, shows chalk lines and is eligible for a lifetime warranty when used as part of a complete system of installation products from Custom. SpiderWeb II has a dual heat-welded fleece design that delivers mechanical bonding to mortar. It's engineered with a sacrificial layer that shears away when exposed to excessive substrate, reports Custom Building Products.
