Hi, I have a Flat Roof ( currently Painted ) that I need to re-seal around 30 Square Meters. I'm a Home DIYer so not a professional can you pls suggest the best product I could use to ether paint on or roller on that has a good elasticity ?
We would suggest Britannia Aquashield High Build for 30m² you would require a minimum of 30kg to apply a single coat to this area.
