Re: lash clips form tradetiler
the trick is to always use the correct notch size for the tile size, ie the bigger the tile the deeper the notch also leveling the floor with leveling compound will help, i also use a tavy puck which helps with leveling and clicks if lippage is present when pushed across the tile edge onto the next tile.
there is a few lippage tools out there from Raimondi, Tuscan leveling system etc the lash seems to be the cheap alternative. seems to me if you have trouble with voids then you need to look at your trowel..i use marshall town 1/2 and 3/8 by 1/4, a 10mm raimondi and a hofman 18mm u also i back butter and mix the standard set so it is soft and easy to trowel i only use rapid on small jobs that need to be done n finished in a day.
