Hello chaps,been on trowel 25yrs,just starting to embrace modern render systems,I have a job come in around 60m2 of OCR and then tryolean.i have used OCR on small jobs before no probs,background is clinker or concrete blocks,new build extension,biggest elevation being 30m2,problem I have I can't get a decent reliable labourer,so am on jack jones,so to control the job I am going to bead up first,then put a tight coat over block work ,embed mesh,client is worried about cracking,then close mesh in with enough gear to give a scratch coat,I will do this all over job first then top coat a day or two later,is it ok to do this,I feel I will be more in control this way,not chasing my tail so to speak,I know you can do 2 passes in same day using OCR,but need to know if my method will be ok,would there be any suction problems etc,comments much appreciated chaps.
