Outdoor pool decks can really take a beating from constant weather exposure and of course, water and moisture. These factors affect the appearance of the concrete surface causing stains, wearing out the color of concrete and promoting mold growth. A pool deck with all these surface flaws can indeed be unsightly. A sealer acts as a protective barrier that keeps the moisture from seeping into the porous surface of the concrete. This keeps the color and finish of your deck in pristine condition and improves its longevity over time.
Step 1: Preparing the pool deck.
Prepare the pool deck by thoroughly cleaning it. This will make sure that the sealant properly adheres to the concrete surface. This also keeps dirt and debris from getting stuck under the sealant. Begin with sweeping the pool deck using an outdoor push broom. Clear apparent stains by lightly scrubbing off with a nylon brush and a cup of trisodium phosphate. Rinse with clean water. Leave the pool deck to completely dry off.
Step 2: Getting the sealant ready.
There are different sealants specially made for different types of concrete pool decks. For example, there are sealants for colored concrete, exposed aggregate, and ones that have slip-resistant additives. Make sure that you’ve chosen the right sealant for your pool deck. If your preferred sealant is ready-mixed you’re good to go. For two-part sealants, mix it according to the manufacturer’s instructions.
Step 3: Applying the sealant.
To apply the sealant, prepare a paint tray and roller brush. Pour the mixture into the tray and roll it in with the brush until it is absorbed. Strategically apply a thin even layer on your deck. Make sure that you have enough space to move around without stepping on the sealer. For a seamless look, avoid overlapping at the edges. Continue doing so until you are able to seal the whole deck.
Step 4: Leave the sealant to dry.
Concrete sealants usually dry completely overnight. However, it is better to follow the manufacturer’s recommended drying time. Make sure that the entire pool deck is undisturbed in the duration of the drying time.
Step 5: Applying the second coat.
Once you are sure that the first coat has dried throughout the pool deck, a second coat may be applied. Simply repeat step 3 and 4. Again, make sure that the coat is thin and applied seamlessly.
Resealing your concrete pool deck every now and then will ensure its protection. For pool decks with decorative concrete overlays, make sure to consult a licensed professional for resealing. This is a necessary precaution to avoid damaging the overlay. Visit our homepage to know more.
