I have a pebbledash house which i want to paint, but I know this may mean having to repaint in a few years. There's an alternative that's a bit more expensive called various names like wall coating, permatex etc. The firms that carry out the work claim to guarantee for 15 years, but they have a hit & miss reputation. I think there are fears that it seals the wall too well and causes condensation/blistering/dampness, but many companies state that the materials are now 'breathable'.
I'm very wary of extravagant claims and can't find much independent opinion. Is it really a better product than just paint?
And how do I find a reputable, local company that won't rip me off? (I'm in Surrey).
