FULL EXPOSURE - for new or old slabs (We grind off 3 – 5mm)
FULL EXPOSURE is where the maximum possible exposure of aggregate (pebbles) is sought.
This finish is absolutely beautiful however one must keep in mind that the evenness of the exposed aggregate and stone patterns that emerge are totally reliant upon the quality of the slab.
Full exposure can be achieved with a remarkable consistency of aggregate density if the slab is prepared by an experienced concreter who understands the finishing required.
A really even 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 which occur where the stones have been pushed down too low.
A consistent slump of concrete mix with each load of concrete delivered will also help to ensure a consistent density of exposure.
If FULL EXPSOSURE is the desired outcome it is important to understand these 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 as the polisher cannot be responsible for the standard of the slab and as such can not guarantee that some screed marks, some areas of lower exposure than desired, or footprints may be visible.
