Contractors use angular aggregates to build more textured surfaces while rounded options guarantee the best coverage. Flat aggregates are the least among the possible choices because they are not that stable. While the size of the aggregate may range more than 2-inches, depending on the exposure level that you want.

However, it can be costlier as the method requires more quantities of aggregate to be mixed on the concrete by batch. The entire procedure would also demand better skills to formulate the right mixture of materials.

Last but not least, is the thin topping method. This works with a smaller quantity of aggregate needed to polish a block of concrete. The thickness of the topping will depend on the size of the aggregate. It will range from up to two inches and not less than an inch. This one is the simplest method that even beginning contractors can follow.
