Re: 10 mm notch trowel? | | thanks for replys. I always used to backbutter all floor tiles. But i suppose with flat tiles you dont have to? I normally put a blob on each corner. No wonder ive been so slow on floors. Its just knowing what you can get away with. when you tile on your own theres no one to tell you whats what. hence why theres so many tilers on this website |
