H&C ClariShield Water-Based Wet Look Sealer is a clear, high-gloss acrylic from Sherwin-Williams’ H&C decorative concrete line, made to deepen color and add shine to patios, walkways, stained concrete and masonry without the fumes of a solvent sealer. It suits homeowners who want a glossy look with soap-and-water cleanup and are willing to apply thin coats carefully. The bottom line: a solid low-odor gloss sealer for decorative surfaces, but it is a thin film that wears and needs recoating, and Sherwin-Williams now says it is not recommended for garage floors.

What It Is / How It Works
This product used to be sold as H&C Concrete Sealer Wet Look Water-Based. It is now sold as H&C ClariShield Water-Based Wet Look Sealer (gloss, clear base, not tintable) in 1- and 5-gallon sizes through Sherwin-Williams stores. The formula and purpose are the same: a 100% clear acrylic resin carried in water.
Like every acrylic "wet look" sealer, it does not soak deep into the concrete. It forms a thin clear film on top. That film darkens and enriches the color underneath, adds gloss, and blocks water, salt, oil and many household stains from reaching the surface. Sherwin-Williams describes the formula as crystal clear, non-yellowing and UV resistant. It goes on milky white and turns clear as the water evaporates, which makes it easy to see where you have already rolled.
Because it is water-based, it has low odor and cleans up with soap and water. The trade-off is typical for water-based acrylics: the film is generally not as deep or glossy as a solvent-based acrylic, and it is less forgiving of heavy coats. If you want a penetrating product that leaves no film at all, see our guide to the best penetrating concrete sealers.
Where It Works Best (and where it doesn't)
ClariShield Water-Based Wet Look is at its best on decorative concrete that you want to look richer: stained or dyed patios, colored walkways, pool decks, exposed block and stucco walls. H&C positions it as a topcoat over its water-based solid color concrete stains, and it can go over previously painted or stained concrete after proper scuffing and cleaning. It is rated for interior and exterior use and for vertical surfaces.
There is one point of confusion worth flagging. Older H&C literature listed garage floors and parking garages among its uses. Sherwin-Williams' current product page says it is not recommended for garage floors, and the regional data sheet says it is not recommended for parking floors. Hot tires and constant vehicle traffic are hard on any thin acrylic. For a garage, look at a coating built for it, such as those in our best epoxy floor coatings guide.
It is also not designed for immersion or areas with constant chemical exposure. Any high-gloss film can get slick when wet, so on pool decks, steps and ramps H&C recommends mixing in its Shark Grip slip-resistant additive.
Pros
- Low odor, solvent-free, soap-and-water cleanup
- High-gloss wet look that brings out stain and color
- Non-yellowing, UV-resistant acrylic
- Goes on milky and dries clear, so missed spots are easy to see
- Works over H&C water-based stains and previously painted concrete
- Interior, exterior and vertical use
Cons
- Thin surface film that wears in traffic areas and needs periodic recoating
- Not recommended for garage floors on the current product page
- Over-application can cause blushing (cloudy, whitish patches)
- Can be slippery when wet without an anti-slip additive
- Etching and a pH check are part of the prep on bare concrete
How to Apply It
- Wait on new concrete. Let fresh concrete cure at least 28 days.
- Clean. Remove dirt, laitance, oil, grease and mildew. For mildew, H&C suggests 1 cup of household bleach per gallon of water (no ammonia or detergents). On painted or stained concrete, scrape and sand anything loose, scuff-sand the rest and degrease.
- Etch bare concrete. Etch until the surface feels like 120-grit sandpaper, rinse, and wait 24 hours. Prepared concrete should test between pH 6 and 10.
- Check the weather. Air and surface temperatures must be between 50°F and 95°F, should not drop below 40°F for 24 hours afterward, and no rain should be expected for 12 hours.
- Test a small area for adhesion and appearance. Do not thin the product.
- Apply a thin first coat with a synthetic 1/4" to 3/8" nap roller, brushing edges and corners. If you spray (airless, 0.013"–0.017" tip), back-roll to remove excess.
- Apply a second thin coat crosswise once the first has dried clear. Very porous concrete may take a third. Avoid puddles, which are the main cause of blushing.
- Let it cure. Keep foot traffic off for about a day and heavier use off for several days.
How It Compares
H&C ClariShield Solvent-Based Wet Look. The solvent version in the same family is the choice if you want the deeper, glassier look solvent acrylics are known for, but it has strong fumes and needs solvent cleanup. Choose the water-based version for low odor or partly enclosed areas.
BEHR Premium Wet-Look Sealer (No. 985). Also a water-based high-gloss acrylic, sold at Home Depot. It lists 200–450 sq ft per gallon, with a similar thin-film profile. The two are close. Pick based on availability and whether you are also using H&C stains.
Penetrating silane/siloxane sealers. If you care more about water and salt protection than shine, a penetrating repellent will not change the look, will not peel and lasts longer. You give up the wet look. See our best concrete sealers for 2026 roundup for both styles.
FAQ
Can you use H&C ClariShield Water-Based Wet Look on a garage floor?
Sherwin-Williams' current product page says it is not recommended for garage floors, even though older literature listed them. Hot tires and constant vehicle traffic wear thin acrylic films quickly. A garage coating is the better choice.
Why did my ClariShield sealer turn white or cloudy?
The usual causes are applying too heavily, sealing damp concrete, or cool, humid conditions that slow drying. H&C specifically warns that over-application can cause blushing. Thin coats on fully dry concrete within the temperature window are the fix.
Can it go over stained or painted concrete?
Yes. It is designed as a topcoat for H&C water-based stains and can go over previously painted or stained concrete that is sound, scuff-sanded and clean. Give fresh stain or paint its full cure time first and test a small area.
Is it slippery?
Any high-gloss film can be slick when wet. H&C recommends adding its Shark Grip slip-resistant additive on inclined or damp surfaces such as ramps, steps and pool decks.
Verdict
H&C ClariShield Water-Based Wet Look is a dependable, low-odor way to add gloss and color depth to patios, walkways and stained concrete. It rewards careful prep and thin coats, and it punishes heavy application with cloudiness. It is not a garage-floor product and not a long-term waterproofer, so plan on recoating every few years. Our rating: 3.7/5.
