A painted or dyed concrete patio is much more eye-pleasing than a plain slab. If you're worried about damage to the finish, sealing it with a protective coat of epoxy can preserve the new color. Epoxy also prevents staining, whether it's from a spill or dreaded moss growth. Although it's simpler to maintain epoxy compared to unsealed concrete, there are still some things you should do so it looks its best.
#1: Add Drainage
Concrete can't absorb water once it has a thick layer of epoxy on it, which can lead to annoying standing puddles if rain or irrigation water gets on your patio. Preventing water splash onto the patio is a simple way to avoid too much puddling.
Installing gutters around your patio overhang, and then routing water away with downspouts, solves the problem without too much labor or expense. If nearby soggy lawn areas lead to water overflow onto the patio, consider installing a French drain system around the patio pad's perimeter.
#2: Sweep and Mop
Epoxy is tough stuff, but it will still get dirty and that dirt can lead to scratches. Sweeping or spraying it off weekly keeps the grit off and the finish looking like new. If it appears especially grimy, mop it with hot water and let it air dry.
When a spill happens, you won't need to worry about it leaving behind a stain. It's still a good idea to wipe up spills quickly though, especially those from food. Otherwise, they'll just attract dirt and possible insects.
#3: Protect the Finish
The legs on your outdoor furniture can eventually scratch the finish on the epoxy. Although this won't compromise its function, it can compromise the beauty of the coating. Place rubber leg protectors on the bottoms of your outdoor chairs and tables. You can also use an outdoor rug to help protect the finish on your patio.
#4: Avoid the Sun
Although more durable than other sealers, epoxy isn't as UV resistant as polyurethane or acrylic sealers. This means constant sunlight exposure can cause it to break down more quickly. Using epoxy only on covered patios provides good protection, but at certain times of the day, the patio will likely still be exposed to bright light. To provide optimum protection, apply a thin layer of a UV-rated polyurethane sealer over the top of the more durable epoxy.
The lifespan of your sealed concrete depends on the brand of sealer you choose, but it it usually counted in decades and not years. Picking a sealer with the longest life expectancy or warranty period is the best way to ensure your sealer lasts for a long time.Share
