As long as your walkway isn’t cracked all the way through, you can coat the piece with a concrete resurfacer, a no-shrink mix of Portland cement, sand, and polymer additives that fills divots and makes an uniform surface. Its natural color is dark gray, so purchase enough to cover your whole walk. One 40-pound bag coats about 35 square feet. If you desire a various color, simply include a concrete tint.

Before resurfacing, strip off any paint or sealants and enjoy the weather condition. Temperature levels ought to stay above 50 degrees F for 8 hours after the put and above freezing for 24 hours after that.

Resurfacing takes the majority of a day, but your walkway will be back in pristine shape when you’re done.

Tidy the Concrete

While using heavy boots and protective glasses, launch surface area dirt with a gas-powered pressure washer that can reach a minimum of 3,500 psi. Fit the wand with a 25-degree fan suggestion, and hold it 6 to 8 inches from the surface area as you clean up the concrete with slow, even sweeps. To remove mildew or algae, use a concrete wash.

Spot Spalled Areas

While the concrete is damp, blend adequate resurfacer to fill any divots. Integrate 1 part water with 7 parts resurfacer in a 5-gallon pail; blend with a paddle mixer connected to a corded drill. Fill the recesses with resurfacer, and smooth with a finish trowel. Go to the next step when you can stand on the spot without indenting it, in about 2 to 5 hours.

Spread the Resurfacer

Fill the pathway joints with peel-and-stick foam weatherstripping, and moisten the concrete if required. The resurfacer is practical for about 20 minutes, so blend simply half a bag of powder with 5 1/2 cups of water at a time. That’s adequate to cover 2 pathway pieces, or about 17 square feet. Put it on the walk.

Trowel It Out

Spread the resurfacer until it’s in between 1/8 and 1/4 inch thick. For a slip-resistant surface, wait 5 minutes, then sweep a nylon-bristle broom across it, 90 degrees to the foot traffic. Remove the weatherstripping after 20 minutes. Wait 6 hours before strolling on it. Cover just if rain threatens in the meantime.
