I really love the oak floor in our family room, but every winter the wood dries out, shrinks and gaps open up. Then in the summer, it expands again. Is there anything I can treat it with now before it absorbs moisture to swell it that it won't lose next winter? I put down a whole quart of Liquid Gold yesterday before leaving the house. I poured it on and squeegeed it around letting it run down the gaps to cover the unfinished edges and the bottom side. It darkened the wood and I had to clean the excess off when I got home. If I really thought it would work, I would be willing to do more. Anybody know if it will or anything else that will work? I don't think I can do a whole lot more on the humidity level of the house. The crawl space under it is very dry for a crawl space. I have sealed the water out. The water pipes don't even sweat in the summer time. In the winter, the moisture in the air is high enough we don't get static walking where we have carpet. I have heard of treating old wool with polyglycols. I have no idea where to buy any except brake fluid, and it is toxic. Whatever I do, the floor has to safe for the dog and visiting grandson. Besides, brake fluid strips finishes off.
