Accidental water contact is no problem as it causes no swelling, melting or delamination. Water permeability is nil with no water drops observed on the rear when water is sprinkled on the front surface.

Tufbloc does not alter its physical appearance or mechanical stability significantly after exposure to water. After evaporation or gravity flow of water, Tufbloc returns to its original state.

Tufbloc is weatherproof. It has been subjected to numerous freeze/thaw cycles and hence is suitable for cold temperate climes too. Tufbloc can be safely used to line the walls and ceilings of wet areas like washrooms and kitchens.
