UN-level floor....What to use to level bathroom floor?
What is the recommended method to level backer/hardiebacker board when you're laying it out for a tile floor installation?
If the only method is to float the floor, what do you suggest for a wood subfloor made of individual boards (with gaps) and not plywood?
We have a 1047 house and the floor is not leve, despite the face we installed 2/4s to create subfloor.
BUT there's gaps of abut 1/4- 1/2 inch.
So....what to use to LEVEL the backerboard we need to lay,....so that the tile and floor is ultimately level????
Thank you in advance!? We are novices.....
