You would be more disappointed if you had seen the different manoeuvres
I was doing in order to create those ridges.........
I actually wipe the substrate as I go along with a damp cloth, just to pick up any dust, etc.
Bud, I am getting better at this tiling thing......They are looking better than the first ones that I laid. I am getting less thinset squeezing out, and I love not using those spacers.
Are tiles no exactly all the same size, or is it just my tiles? Sometimes I notice that some are off about 1/16th of an inch.
