TECH-DRY DAMP COURSING FLUID is a silane/siloxane-based impregnant specifically formulated to permeate into wet walls. Once impregnated into a course of brickwork, DCF reacts with the minerals present to form a durable polysiloxane damp course which stops rising salt damp. Tech-Dry Damp Coursing Fluid was developed and tested at the Victoria University of Technology Building Protection Science Unit. It has been used in over 30,000 successful damp course installations Australia-wide, both in domestic and commercial properties, as well as some important heritage buildings since 1982. Features: Penetrates deeply into bricks, mortar and other masonry substrates. UV, alkali stable and durable formulation. Reduces water penetration, salt migration and other water-borne staining. Non-dangerous, non-corrosive and non-toxic formulation. Easy application. Please note: If selecting Local Pickup. Our new office is located at 1/2-4 Byre Avenue, Somerton Park, SA 5044.
