Touch dry in 2 hours. This flexible undercoat is specially formulated for use on wood to resist cracking, providing the perfect base for the top coat gloss. Newly painted doors and windows should not be closed until paint is fully dry.
Not a bad undercoat, but being water based it goes on pretty thin so 2 full heavy coats are definitely required. Given the choice i would not buy this again and would go for an oil based paint, but as it is just an undercoat perhaps i would try it again. The cost for a 2.5l tin was quite high in my opinion, but not sure what better priced alternatives exist.
