How thick does the topcoat need to be

I am doing my first GRP roof, can you tell me how thick I need to apply the topcoat?

Depending on temperatures the coverage rate for the finishing topcoat should be around half a litre of topcoat per square metre. In colder weather the finishing topcoat becomes thicker and doesn't apply as easily so allow 1 litre per square metre.

For more information check out our topcoat application guide or give us a call.
