The CBS School in Mitchelstown had problems with a leaking flat roof of approx 180m2 in size. We firstly stripped off the Sarnifil which was the previous waterproof coating. We then proceeded to power-wash the roof to clear off any bits of the old covering remaining and any dirt left on the roof. We then hoovered the water to ensure the surface was dry prior to our application of the Universal Primer. Once this had dried (approx 20 minutes later) we then proceeded to apply two coats of Rapid Roof to the surface. We power washed on a Thursday and completed the roof by Friday evening due to the rapid curing times of this superb product.
