There are lots of concrete mix products on the marketincluding mortars, repair patchers, fast-setting concrete mixesand it can be hard to choose among them.
Unlike other cement products, it is designed to be applied in extremely thin coats (no more than 1/2 inch thick), and its additives offer good adhesion to an existing piece. Concrete resurfacer is a very strong product, ranked for a compressive strength of about 4,500 psi. This is actually stronger than the piece itself, so correctly used, resurfacing layers can be very resilient.
This can be hard to determine, but if the height of the slab is balanced out on adjoining sides of cracks, it is an indication that significant heaving is taking place. Such a piece is probably not a great candidate for resurfacing. However a slab with small cracks, chips, and spalls where pieces of aggregate have actually come loose is a perfect candidate for resurfacing.

Constantly invest in a real concrete resurfacer when restoring a concrete slab. Thorough preparation is the crucial to lasting results when resurfacing concrete. This preparation involves pressure-washing the piece, repairing substantial damage utilizing a quality concrete patch item, and getting rid of any stains from oil, paint, or tree sap.
The application of concrete resurfacer is quite a simple procedure. The dry powder is blended with water to form a slurry, which is then spread out over the concrete piece using a long-handled squeegee. Resurfacers are self-leveling, suggesting that they do not need to be worked thoroughly to produce a level surface area.
You do not need to fret about trowelling to a level surface, as you do when putting a slab with new concrete. If you are resurfacing a slab with growth joints, don't cover over the joints with resurfacer. Instead, cover the joints with duct tape to avoid the resurfacer from staying with them.
