My garage roof is asbostive and it lets water in. what kind of paint shuld I use. thanks


We are assuming you have a pitched 'asbestos' sheet roof, so after cleaning (seek advice from your local authority on guidelines for this) then we would recommend applying Rust-Oleum Mathys Primer 44 HS followed by Rust-Oleum Mathys Dacfill Waterproofing. Refer to product data sheets for full details on preparation, application, etc.
