Delta Polysil TG500 10kg

Delta Primer

Delta Polysil is a deep penetrating primer for damp, salt-containing substrates. It is generally used before the installation of a Delta cavity drain membrane system. It can also be used as a lime inhibitor in new concrete to prevent free lime ingress. is compatible with mortars, plasters, cementitious slurries and with concrete.

How does it work?

When the primer is sprayed onto the surface of a wall, it penetrates into the capillaries. As it does so it causes the pore volume to reduce, which helps prevent salt efflorescence and free lime ingress. It also increases the chemical and mechanical resistance to mineral building materials.

Uses of Polysil

Delta Polysil is commonly used when cavity drain membranes are to be fitted to new concrete walls and floors. Once treated, the risk to the concrete from leaching of free lime and/or mineral salts is reduced.
