Large knots in oak flooring, want to fill it with clear epoxy?

We bought new 5'; wide utility oak flooring, they have many imperfections from large 2'; knots with the depth of 3/4'; to the little knots. I know I can fill it with wood putty... question, can I use anything, like a clear liquid to keep the 3 dimension knots visible but would also take to polyurethane over it?





The small knots and imperfections will of course be filled to wood putty. The stain on the flooring with be a dark color.Large knots in oak flooring, want to fill it with clear epoxy?
2 part polyester resin will work- most hardware stores can get it for you. it's a resin %26amp; hardener mixture which will cure regardless of depth- i have used it for bars, countertops, cypress clocks, etc. it remains clear, and you can go over it with poly.Large knots in oak flooring, want to fill it with clear epoxy?
Hi,


Oak flooring inherently does not have knots, if you fill the areas with a clear resin make sure you lightly sand the finish to allow the poly to adhere properly.
Don't: Fill the knots with ';Durhams'; rock hard wood putty. A powder but, fill the holes half way until you have about 1/4 inch left than fill to the top and sand. Allow at least overnight to solidify.
Epoxy will seal the wood. The stain won't penetrate.





There is a product called ';wood conditioner'; that is made for this.
Use the resin it's fast and cheap,but you have to work fast before it hardens.I suggest mixing a little at a time.
you can use resin it's available at most craft stores
