What is Full Exposure?
Full Exposure is where the maximum possible exposure of aggregate (pebbles) is sought. This finish is both striking and beautiful, however, a perfectly balanced exposure of aggregate is completely reliant upon the quality of the concrete slab!
A Full Exposure grind can be achieved with a remarkable consistency of aggregate density when the slab is prepared by an experienced concreter who is aware and understands the finishing required.
Full Exposure is not difficult to achieve with a professionally poured slab, where the concreter knows how to prevent screed bar marks, footprints and bare edges, where the stone has been pushed too low. A consistent slump of concrete mix with each load of concrete delivered is a method that helps ensure a consistent density of exposure.
As a client, if you, your architect, or designer desire a Full Exposure look it is crucial you’re aware of the above principals. Most experienced concreters will be able to deliver a slab along these lines, should you request it.
We can’t STRESS enough how important it is to have a good concreter. We cannot be responsible for the standard of the slab and as such cannot guarantee that possible screed marks, areas of lower exposure than desired, or footprints may be visible.
