In comparison to certain other types of home renovation and restoration ventures, resurfacing concrete is a comparatively simple process that can be accomplished using concrete resurfacing materials that are readily accessible at any home improvement shop or hardware store. If the surface of a concrete slab or structure is cosmetically damaged but still in reasonable condition, resurfacing is an excellent choice. Although resurfacers cannot repair deep cracking or heaving, they may conceal routine flaking of a best concrete resurfacer reviews or tiny spalling pits. For eg, a concrete slab that has been weakened by road salts may be quickly renewed with a coat of resurfacer.
If you take the time to thoroughly plan the surface, apply the resurfacer carefully according to the manufacturer’s directions, and give enough time for the resurfacer to cure, you’ll be rewarded with a garage floor, pavement, sidewalk, or patio that looks brand fresh.
Products for Concrete Resurfacing
All of the big concrete component suppliers, including Quickrete and Sakrete, offer concrete resurfacing goods. These are usually composed of a mixture of Portland cement, fine sands, polymer changing substances, and other additives that render the surfacer simple to apply and scatter across established concrete surfaces. They can be applied in thin layers ranging from 1/16 to 1/2 inch deep. These specialty mixtures are relatively costly, but when used properly, they may restore the appearance of a concrete slab.
Concrete resurfacing materials are designed to patch just the most shallow gaps and pits in concrete. For more extensive repairs, such as large cracks or those with minor vertical changes, you must first cover the affected areas with a patching compound, such as Sakrete’s Top ‘n Bond, and then do a full resurfacing treatment.
Restore the Subsurface
Resurfacers for concrete can be treated as aesthetic enhancements, not as maintenance materials. Where widespread damage occurs, resurfacing can only temporarily conceal the issue. However, if the surface has only small cracks or pits, resurfacing can be useful if you first fix the damage with a patching tool.
Repair some significant harm to the concrete with another concrete patching tool and allow it to properly dry before continuing with the resurfacing.
Surface Cleaning and Preparation
It is important to thoroughly scrub the concrete surface of any loose particles. Although a powerful garden hose spray and a long-handled scrub brush will suffice, a good pressure washing can provide a more thorough clean.
Additionally, you can clean the concrete of any oil stains, wax, or tree sap. If your attempts are unsuccessful in completely removing the mark, try adding a sealer over it before resurfacing. If the stain is not sealed, it would almost certainly bleed into the resurfacing sheet.
It is important to secure expansion joints when applying resurfacer. Using duct tape or weather stripping, mask off these control joints to avoid the resurfacer from filling them up.
Resurfacer must be added to a wet surface to prevent the concrete from sucking moisture from the resurfacer during curing. Only prior to combining and adding the resurfacer, spray the slab with a hose to cool it off and brush out any stagnant water.
Incorporate the Resurfacer
Mix and add one bag of resurfacer at a time for the optimal performance. Typically, a 40-pound bag would take six pints of water. When the weather is high, use warm water; when the temperature is humid, use cold water. At 73 degrees Fahrenheit, you will have about 20 minutes to deal with the resurfacer until it hardens.
Fill a clean 5-gallon plastic bucket halfway with water, then add the resurfacer and stir for many minutes to achieve a nice, pourable consistency. Allow the contents to settle for a few minutes before mixing it again. If required, add additional water or resurfacer to produce a pourable mixture with the consistency of syrup.
Concrete coloring agents can be applied to the mixture at this stage, only prior to application, if needed. Ensure all the paint agents you choose are consistent with the resurfacer; it’s a smart thing to use materials from the same maker.
Resurface with Resurfacer
Pour a tiny volume of concrete resurfacer onto the surface and then begin distributing it thinly using a light, long-handled squeegee. Additionally, resurfacer may be added using a trowel or blade.
At a time, work in segments of no more than 144 square feet. Where practicable, segment the job such that you are still working along the control and extension joints’ edges.
At the slab’s sides, you can use a concrete edger to build smooth, professional-looking edges, but only if you get to them within the first 10 to 15 minutes of application.
Allow two or three hours for the surface to cure completely before applying a second coat using the same technique. While the majority of suppliers prescribe a second coat, this is optional; the choice should be focused on how well the first coat concealed minor imperfections.
Rubble the Surface
Allowing the resurfacer to cure without applying any finishing touches results in a clean base. That is frequently all one desires in a garage. However, the shiny finish may be dangerously slick when wet, making it unsuitable for use on a road, pavement, or patio.
To add dimension or “tooth” to the finish, sweep a long-handled broom over the surface in broad strokes. This can be done within five minutes of application, when the mix is already sufficiently warm. Assure that all broom strokes are parallel to one another.
Allow for the cure of the resurfacer.
The concrete resurfacer hardens and gets smoother when it cures. Allow about eight hours to move on resurfaced concrete and at least two days to drive on it.
When curing, the resurfacer should be held mildly damp. Covering the surface with plastic is only required to shield it from rain directly after application, although it should be gently misted with water once or twice daily over the first two days.
