We are going to be putting down 7 1/4" white pine flooring in our house. If we were to simply sand this down and apply varathane (no staining), how many coats of good quality varathane for a durable coating. Is it true that the first two applications soak into the pine like a sponge so 3 coats wouldn't get you much. Would applying a conditioner prior to varathane seal it up and prevent this rapid soaking. We know pine will mark, we just want to help slow the process with the proper coating. Thanks for your help.
