Waterproof Water Tank
Ensure a clean, dry surface using Cohe Quick Clean.
Make sure the water tank isn’t connected to any downpipes that lead into the water tank.
Bridge joints, seams, vents and cracks with Liquid Rubber Seam Tape.
Apply 1 layer of Liquid Rubber Primer. 1 litre does 2 square metres. Leave it to dry for 12 hours.
After applying each layer. Use as many ventilation systems to get the inside air flowing out of the tank. Also, use heating when necessary.
Apply Liquid Rubber Waterproof Sealant using a brush or roller all found in our Application Kit.
– apply a minimum final thickness of 1 litre per 1 square metre it should be around 2-3 heavy coats.
– a 20 litre pail will coat up to 40 square metres. For larger areas, you can pour out and roll around.
Apply the next layer after 12 hours. Tacky is ok.
Do not connect the water tank to the downpipes for at least 14 days.
