Screed isn't the best surface for polishing as you cannot put a strength on it. The 10-20mm aggregate in the concrete provides the strength and the cement acts as the binder, so concrete needs to be used. Optimum strength for polishing is between 30-35n. You have to decide what aggregates, intregal colours etc you want to use to acheive the finish you are looking for.
Things to take on board are, control joint placement, the use of polypropene fibres, concrete slump should be consistant, concrete should come from same source for entire floor keeping the materials consistant, concrete should be vibrated to ensure there are no airholes in the concrete once grinded etc. We provide a briefing paper which includes the elements to be considered, for contractors, architects, and clients so that everyone is aware of what has to be done. These are normal practices and with a little thought and planning you can have a truely unique floor finish.
Ranley use the latest innovative dry grinding methods of polishing concrete. We use the latest HTC machines and tooling to provide this service in Ireland. The old method of wet polishing is not used as much today as dry polishing can leave a better finish without the mess of sludge etc when using water. Our process is dustless as we use the latest dustless technology.
All Ireland coverage.
