Its about your timings, use very very little water, only work in straight lines and keep changing how you use it till you find the way that works for you. Having said that the blue st is so good I barely use my sf now
Tried 18" from other mate and it's super! Flatten out. Just joking about 28" but could give it a go as like trying new kits!
Don't get it. Got the blue blades today.look exactly the same as the grey ones ?? Same flex same thickness ?How come they are better
Ridges dont go all the way down + the blue blade slightly thicker, miles better to use, been goin over walls/ceilins twice wth mine + one trowel after that its done, so much easier!
