I think these systems could help a bricky,plumber,builder, keen -amateur ,produce a job as good as any tiler, with-out them having to hone there skills , so IMO they could be yet another factor in giving other trade's /semi skilled,a hand in taking tilers works/jobs away from the marketplace ......BUT HAY thats what it's all about !!!! undermining all trades so the general masses can do there own jobs without having to employ a specialist ,the government have been doing this to us for years, just when it had got to a good wage
standard for all in the construction industries the gov flooded the market with cheap foreign labour/health & safety stuff
the sparky s & plumbers have done the right thing by protecting there trades a bit......
