billyo Posted December 8, 2006 Share Posted December 8, 2006 Hi all,Does anyone have any experience in pressure washing concrete? As in, is it just a noemal mix that can be laid by hand, painted (although not sure why) and then pressure washed 12 hours later to give the finish, or am I missing somthing very important? And is there any reason why it cant be used as a finish for a swimming pool terrace?CheersBillyo Link to comment Share on other sites More sharing options...
darkmetal Posted December 8, 2006 Share Posted December 8, 2006 Hi how do you mean painted i worked in the building trade and what i think you may be talking about isa) you lay the concrete , screed and float itb) later the same day or the following day spray or paint it with a type of cement retarderc) after a few days you powerwash the top layer (about 3 - 5 mm) of cement off which in turn leaves you with a pebble dash finish and its fine for a pool terrace is that any helpalex Link to comment Share on other sites More sharing options...
