homebuildandrenobuddy.com G’day Everyone, Today we are having a look at a type of concreting called Pebblecrete (or exposed aggregate for technical people). This type of concreting is installed exactly the same way as any normal concreting would be except instead of doing a final smooth trowel finish or a broom or sponge finish, the concreters actualy hose the top off. How it works is that they pour the concrete, screed it off like normal and then they wait a bit for it to start to go off like normal but then they spray it with sugar water. That’s right a simple mix of Black and gold sugar and water gets sprayed on the surface (repeatedly if need be). What this does is allows the underneath of the concrete to start to set and cure but does not allow the slurry on the top of the slab to set or cure. When the concrete reaches a stage that you can get on it and walk on it with out sinking, the concreters then hose the slurry off the top leaving the exposed stone as the finished product. You can not just use normal stone mix as say for a house slab, you must use a much finer stone mix and a lot more stone in the mix. It is a little bit dearer but comes up a treat and can actually set your finished project off nicely. Cheers, You’re Buddy, Dion
