hi, im ian im currently training to be a plasterer mainly looking to board and skim, and screed floors... after reading a lot of articles on here i was wondering wether it would be a good idea to buy and use a speed skim plaziflex or s*p*r*lex while i was training and if so what i should be looking to buy and why.. some pro's and con's of each tool and times (adjusting times etc) would be great.. i already went out and got myself a 14" marshalltown permashape as the college trowels were shite and basically thought it might be a good idea to learn to use some of these other tools while training.. any insight is welcome, thanx in advance....
