I don't think so, it says resistant to condensation, if gathers condensation on surface then leads to mould, it says mould resistant on the tin, it's similar to bathroom paint and perma white. Better than matt and silk when comes to condensation, matt being the worse. I spoke to Dulux; they recommended their own diamond eggshell but twice the price of johnstones, I need 20 litres so big difference in cost for similar spec product.
