I have a spot in my kitchen floor where the prior owner cut through the flooring to have a wood stove installed. The cutout is approx. 1/4 inch deep, but it is not the same depth all over, give or take here and there. I would like to fill this hole in so I can put down new flooring (not sure on tile ot vinyl). Any suggestions would be greatly appreciated on what i need to use to fill this in. I am clueless to do it yourself type work (this will be my first project) :)
I wouldn't fill if in with anything permanant. I expect that someone will want to rip all of that down to the subfloor and start over someday. I am not a professional, but I would maybe fill that in if I know the bottom layer would come up if needed.
Please don't add a 4th layer unless for some reason there is asbestos adhesives involved in all this.
