Hello, I'm a painter and decorator. I'm about to undertake work on a exterior job where I will be painting the render in masonery paint and the all the wood work on this one particular wall in water based gloss . The client has asked me if there is a product I could paint over it all once I'm done to protect it from the elements. Do you have anything for this please
We wouldn't recommend anything for this really, you could use an anti-graffiti coating like Hydron Nu-Guard AG but ideally the paints you are using for each substrate if good should protect them in their own right.
