Thin resurfacing can make old damaged concrete look almost new without having to tear the surface out and re-pour. This is a real savings in labor and materials. Recent developments in resurfacing materials now offer a durable, stain-resistant, crack filling resurfacing mix of epoxies and aggregate. This dries quickly and is ready to use in a fraction of the time it takes traditional mix to harden. This is a big asset in high-traffic areas.
Resurfacing concrete can offer the opportunity to enhance the existing floor with an exciting new decorative concrete finish. It can be stamped, colored or stained and polished to look like marble, terra cotta stone, and even stenciled.
The basic re-surfacing process is simple enough to be tackled by a do-it-yourselfer with just a little bit of experience in concrete. Required basic tools include a container for mixing the material, a mortar towel, a float, and a stiff broom to rough the surface enough to make it non-slip. Renting a power washer is recommended, as are protective clothing and goggles.
Measure the area to be resurfaced to determine how many bags of concrete mix you will need. Use duct tape to mask areas that need to be kept clean, including the control joints. Cleaning the surface before beginning is critical; here’s where that power washer will come in handy.
Mix the concrete, following directions on the bag, adding water in increments until you’ve achieved the appropriate consistency to spread well. Wet the surface before applying, but not enough to leave standing water. If the resurfacing has to be smooth, run a concrete float over the surface while the mix is still wet. This is practical only when working in one small area at a time, before the concrete hardens.
Mask areas that need to be kept clean, including the control joints. This can be done with duct tape.
Running a broom over the surface while it is still wet will make it more slip-resistant.
Keep all foot traffic off the fresh concrete for at least 6 hours. Check your product for the expected drying times. More time is needed if the temperature is cool. Covering the surface with plastic can help it to cure without cracks.
