QUESTION:
I just finished acid staining the colored concrete patio around my pool. I'm located in central California, summers here have a few days over 100 degrees.
What can I use for a durable concrete sealer that will enhance/darken the coloring, add a semi-wet look, and is not slippery (due to the pool).
First off, congratulations on completing your acid-stained concrete patio! Acid staining is a fantastic way to add rich, variegated colors to concrete, and sealing it properly will ensure longevity, durability, and enhanced aesthetics.
Since your patio surrounds a pool, you need a sealer that achieves three primary goals:
Based on these requirements, let's break down your best sealer options.
Acrylic Sealers (Solvent-Based or Water-Based)
Pros:
✔ Enhances color significantly (solvent-based)
✔ Provides UV resistance, preventing color fading
✔ Fast drying and easy to reapply when needed
Cons:
✘ Can be slippery if not properly treated with an anti-slip additive
✘ Solvent-based options have strong fumesRecommended Products:
Penetrating Sealers (Silane/Siloxane Blends)
If slip resistance is your top concern, a penetrating sealer is an option. These sealers soak into the concrete, forming a hydrophobic barrier that repels water while maintaining a natural matte finish. However, they do not enhance color or add a wet look.
Pros:
✔ Excellent water and chemical resistance
✔ No surface film, so they won’t be slippery
✔ Long lifespan (5+ years)
Cons:
✘ No color enhancement
✘ No glossy or wet-look finishRecommended Products:
Urethane and Epoxy Sealers
Urethane and epoxy sealers provide unmatched durability but are generally not recommended for outdoor pool decks. They create a thick, glossy film that can be dangerously slippery when wet.
Pros:
✔ Extremely durable, long-lasting protection
✔ Excellent chemical resistance
Cons:
✘ Can be too glossy and slippery
✘ More difficult to apply and removeRecommendation:
Since safety is a concern, I do not recommend urethane or epoxy sealers for your pool deck.
Because you're sealing an area around a pool, preventing slipperiness is crucial. There are two ways to make a solvent-based acrylic sealer safer:
A. Add an Anti-Slip Additive
Anti-slip additives mix into the sealer before application, creating a slightly textured surface without compromising the wet look.
Best Anti-Slip Additives:
B. Use a Low-Sheen or Matte-Finish Sealer
If slip resistance is a major concern, you may want to choose a low-sheen or matte-finish acrylic sealer. These offer mild color enhancement without making the surface overly glossy.
Recommended Matte-Finish Sealers:
Considering your requirements — color enhancement, durability, and slip resistance
I recommend:
Primary Sealer: Armor AR350 Solvent-Based Acrylic Sealer (for a semi-wet look and UV protection)
Anti-Slip Additive: Foundation Armor non-slip additive
PRO TIP: You can cut the solvent sealers with a little Xylene (.5 gallon Xylene to 2.5 gallons sealer) to help it spray thinner out of a pump up sprayer.
PUMP UP SPRAYER I RECOMMEND: Chapin Stainless Steel 2 Gallon Sprayer
If you prefer a water-based alternative, go with SureSeal Super WB, but note that it won’t darken the stain as much as a solvent-based option.
By selecting the right sealer and applying it correctly, you’ll not only enhance the beauty of your acid-stained patio but also ensure its longevity and safety in the hot California climate.
Stick with a high-quality acrylic sealer, use an anti-slip additive, and maintain the surface every couple of years to keep it looking its best.
