Hi am laying osb floor in shed your pro block seems to come out on top re sealing surface prior to painting with oil based top coat any advice would be grateful thanks
We are not sure what product you are referring to as 'pro block' but if you wish to paint your OSB shed floor with a solvent based floor paint we would suggest Rust-Oleum 7200 Floorcoat PU. Dilute your first coat with 5% volume Rust-Oleum Thinner 633.
