Salt Water Pool Woes: Concrete Sealer Tips
Salt water pools are all the rage these days for both residential and commercial installations. Without question salt water is an improvement over chlorine, but even salt can have an impact on sealed decorative concrete finishes over time.
Once water splashed on the poolside concrete begins to evaporate, salt crystals form and adhere to the sealer surface. At the microscopic level, salt crystals are quite jagged in shape and begin to damage the sealer finish with repeated exposure. The question is what can be done to prevent the damage?
Here Are a Few Simple Suggestions That Will Make a Difference During the Summer:
- Select a Satin Rather Than High Gloss Sealer: High Gloss Acrylic Sealers can create slip hazards when wet and are not appropriate for the pool deck. Our Sprayable Satin Finish Sealer is a much better option for a satin gloss acrylic option and will need to be reapplied once every 2-3 years. 777 Modified Acrylic Urethane offers 5+ years of protection and could be used on pool decks or patios. An anti-slip grit product can be added to the sealer to reduce slip hazards if desired.
- Having a Pool Party? Rinse Off the Deck Afterwards:
Salt water will damage concrete sealer over time but washing the deck off with your garden hose after extensive use will make a big difference in both sealer appearance and long term durability.
- What Do I do if Salt Deposits Occur?: First, make sure the discoloration is due to salt water. Irrigation often leaves hard water deposits on concrete and often leaves a milky, powdery-like residue on concrete over time. Apply full strength vinegar to the affected area first to see if the material dissolves away after cleaning. If not, it’s time to get out the power washer to carefully clean off the salt residue from the surface without damaging the sealer finish. Wait until the concrete is completely dry to evaluate whether or not the cleaning was successful.
- Time for a Reseal?: Most pool decks sealed with an acrylic sealer will need to be resealed every two to three years. Once the concrete is clean and dry, apply the sealer (spraying is always the best method) and allow to dry. Repeat. Two coats is always better than one with acrylic sealers. Most modified urethane, polyurea or polyurethane will require a light sanding before re-application so know what sealer you’ve used in the past before applying anything else.
