Most homeowners think about concrete maintenance in the fall, when everyone is talking about winterizing the house. But summer has its own set of concrete challenges — and ignoring them means starting the next season with a surface that’s already behind.
Indiana summers bring intense UV exposure, heat, heavy use, and the kind of traffic that puts real stress on outdoor concrete. Here’s what Swackhamer Masonry & Concrete recommends for keeping your concrete looking and performing its best from Memorial Day through Labor Day.
UV Fading Is Real — Especially on Stamped Concrete
Plain gray concrete doesn’t show UV fading the way decorative concrete does — it starts gray and stays gray. But stamped concrete, with its color hardeners and integral pigments, is more vulnerable. Direct summer sun over multiple seasons gradually bleaches the color, leaving surfaces that looked vibrant at installation looking dull and washed out a few years later.
The most effective defense against UV fading is a quality sealer with UV inhibitors. If your stamped concrete hasn’t been resealed in the last year or two, midsummer is actually a great time to do it — warm temperatures help the sealer cure correctly, and you’ll be protecting the color through the peak sun exposure months.
Keep It Clean More Often Than You Think
Summer means more outdoor activity, which means more opportunity for your concrete to accumulate stains. Grease from the grill, fertilizer overspray, sunscreen, food and drink spills — all of these can penetrate an unsealed surface and leave permanent marks.
The easiest stains to deal with are fresh ones. Get in the habit of rinsing your patio after cookouts, wiping up spills promptly, and doing a light pressure wash every month or so during peak season. For sealed surfaces, most everyday stains will lift easily with water and mild soap. For unsealed surfaces, act fast — the longer a stain sits, the harder it is to remove.
Be Mindful of What Goes on the Concrete Surface
Summer brings a lot of things onto concrete surfaces that can cause problems if left too long:
Fertilizer and lawn chemicals: These can stain and in some cases chemically affect concrete. Rinse overspray off concrete surfaces promptly.
Metal furniture and planters: Rust stains from metal chair feet or the bottom of terracotta pots are some of the most stubborn concrete stains there are. Use rubber feet on metal furniture and lift planters onto pads or stands.
Pool chemicals: If you’re draining or backwashing a pool near concrete, be aware that high-chlorine water can affect some sealers and stain unsealed surfaces. Dilute heavily and rinse the area.
Patch of grass killer: Herbicide overspray on concrete won’t hurt the concrete itself, but it can leave a discolored mark. Rinse thoroughly.
Summer Is the Right Time for Repairs
If you’ve been putting off a concrete repair — a crack you noticed in March, a joint that’s starting to open up, a section that settled over winter — summer is the time to address it. Concrete repair products and sealers cure best in warm temperatures, and addressing issues now gives the repair time to fully harden and stabilize before the freeze-thaw season starts again.
Waiting until fall often means rushing — trying to get work done before the temperatures drop. Summer gives you more runway, better curing conditions, and the satisfaction of having it handled before you need to think about winter.
A Midsummer Rinse Makes a Real Difference
This is the simplest advice we can offer and the most frequently ignored: rinse your concrete regularly throughout summer. A garden hose and 10 minutes every few weeks removes the gradual accumulation of dust, pollen, organic debris, and surface contaminants that, left alone, slowly work their way into the concrete.
For sealed surfaces, regular rinsing also keeps the sealer performing well by preventing buildup that can make the surface look dull even when the sealer is still intact. It’s not glamorous maintenance — but it works.
