I have a small garden shed 6x8 feet about 20 years old. No cracks in asbestos roof but water now seeps through sheets. Which is the most suitable product to make waterproof? Many thanks.
Assuming the asbestos roof is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Eagle Bitumen Primer followed by Eagle DoubleCoat Pro-Reflect Liquid Waterproofing.
