Concrete Resurfacing In Mildura

It depends on why it is cracked or spalling. Fine, stable surface cracks can be routed out and repaired before the overlay goes on, and hairline crazing is usually no problem. But if the slab is still moving, or the surface is flaking because salt and a shallow water table have got at the concrete and reinforcement, an overlay will not fix the underlying cause and will eventually crack or lift with it. We check the slab first and tell you straight whether resurfacing will hold or whether replacement is the better spend.

Yes, a lot, which is why timing matters so much here. Resurfacing overlays are thin, so in 40 degree heat with low humidity and wind they lose water very quickly, and if that happens before the material has bonded you get poor adhesion, patchy colour and surface cracking. We manage it by pouring early in the morning, setting up shade and windbreaks, and misting or curing the surface as it sets. In peak summer we will sometimes schedule your job for a cooler window rather than rush it on the worst day.

When it is bonded to a sound slab and prepared properly, a quality overlay holds up well for many years of normal use, and periodic resealing keeps it looking its best. Its life is tied to the slab underneath, though, so if the base later moves or fails the surface will follow it. Regular light maintenance and keeping the surface sealed goes a long way, especially outdoors where the Mildura sun works on everything. We will give you realistic expectations for your particular slab rather than an open-ended promise.

Yes, these are some of the most popular resurfacing jobs we do. A trowel-on or spray-on overlay can transform a plain or dated pool surround or alfresco slab, and we can add a lightly textured finish so it stays reasonably grippy underfoot when wet. For pool areas we favour lighter colours because they stay noticeably cooler in Mildura's summer sun than dark surfaces do. As with any resurfacing, we make sure the existing slab is sound and drains properly before we start.

No, that is the whole point of resurfacing; you keep the existing slab and we bond a fresh surface over it, which saves the demolition and disposal cost of a full replacement. We do grind and clean the surface and repair any defects so the overlay grips, but the slab stays put. If the concrete is too far gone to build on we will tell you, because there is no sense laying a new surface over a base that is failing.

You can usually walk on a resurfaced area within about a day, with vehicle traffic held off a driveway for several days while the overlay and sealer cure fully. Curing times shift with the weather; the dry Mildura heat can speed the initial set but we still allow proper curing so the finish reaches full strength. We will give you clear timings for your specific job when we hand it over, along with simple advice on keeping it sealed.
