FBS.172.17 Hardwood Floors Ad final.pdf 1 11/10/17 3:57 PM Moral of the story: When planning to coat waterbornes over oil- modi ed stains, sealers or nishes, know your region, including seasonal variations, and adapt accordingly. Be aware of how your substrate preparation can a ect the dry time. Most importantly, use fans and windows to exchange the air in the roomwith new air. Other variables that can extend the recoat time of oil-modi ed stains, sealers or nishes on raw wood: • New wood (= open/unsealed bu ends, for more absorption and slower evaporation), • Water-popping (worse if water has not completely evaporated before staining), • Double-staining (= more stain), • Hot-coating over it with an oil-modi ed sealer or nish, and • Situations where the air temperature may not re ect the temperature of the substrate (like in a new situation where the heat has not been on long enough, particularly in basements or new construction).

Well, the nal coat is down: a silky-smooth blanket of polyurethane perfection. e customers are waving and crying as you wink, turn on your heel and walk o into the sunset. And, since you treated them right, your stains, sealers, and nishes will speak highly of you long a er you are gone. Boy, it feels good to be a wood ooring professional.
