A bluestone patio fails slowly: fading first, then joint sand loss, then winter spalling where water sits too long. The right sealer won’t make stone maintenance-free, but it can cut absorption, deepen color, and make cleanup easier across 12 months of sun, rain, and freeze-thaw movement. Pair the surface plan with outdoor patio rugs, patio furniture covers, patio side tables, cantilever patio umbrella, and solar lanterns for a patio so the whole space works, not just the stone.
How We Evaluated
I prioritized water-based formulas, wet-look performance, joint-sand control, coverage claims, container size, and suitability for outdoor hardscape materials. ASTM weathering references matter here because bluestone sees UV, standing water, abrasion, and temperature swings in the same season. I also weighed manufacturer durability language, VOC practicality, gloss level, and whether a 2.5 gal or 5 gal format makes sense for a 300 to 800 sq ft patio.
1. Black Diamond Stoneworks GET SERIOUS Paver Sealer Super Strong Concrete Paver Sealer and Sand Lock All-in-One. Water Based Wet Look Sealant for C — The practical all-in-one for loose joints
This one wins for homeowners who want color enhancement and joint stabilization in one pass. Black Diamond Stoneworks positions GET SERIOUS as a water-based wet-look sealer with sand-lock function, which matters on bluestone patios with polymeric sand gaps or older swept joints. Rating is listed as unavailable, so the spec sheet carries more weight than social proof. It’s best for patios where erosion between stones is the visible problem. Not a miracle fix. Bad base prep still shows through.
2. DOMINATOR High Gloss Wet Look Paver Sealer 2.5 Gallon – Water Based Paver Sealer for Outdoor Driveway, Patio, Brick, Fla — The smaller high-gloss job size
DOMINATOR’s 2.5 gal High Gloss Wet Look Paver Sealer is the better fit for compact patios, landings, and partial refresh work. You’re not buying more pail than needed for a 250 to 500 sq ft project, and the water-based formula is simpler for cleanup than solvent-heavy options. Rating is unavailable, so I’d judge it by surface compatibility and gloss preference. It’s the pick when you want a stronger wet look without committing to a 5 gal container.
3. DOMINATOR High Gloss Wet Look Paver Sealer 5 Gallon – Water Based Paver Sealer for Outdoor Driveway, Patio, Brick, Flags — The large-patio gloss option
Choose the 5 gal DOMINATOR High Gloss if your bluestone patio is closer to a full outdoor room than a walkway. The larger container makes sense for broad surfaces, borders, and second-coat planning, especially around dining zones where spills and foot traffic repeat weekly. Rating is unavailable, but the product’s advantage is format: fewer container changes and better batch consistency across big areas. It’s glossy, so don’t choose it if you want the stone to stay visually quiet.
4. Black Diamond Stoneworks GET SERIOUS Paver Sealer Super Strong Concrete Paver Sealer and Sand Lock All-in-One. Water Based Wet Look Sealant for C — The repeat pick for sand-control coverage
This Black Diamond Stoneworks GET SERIOUS listing belongs here because the all-in-one sand-lock angle is unusually relevant to bluestone. Natural stone patios often have wider, less uniform joints than poured concrete slabs, and those joints are where washout starts after 1 hard storm. Rating is unavailable, so it’s not a crowd-score pick. It’s a function pick. If you’re tired of sweeping sand back into the same gaps every month, this is the product type I’d look at first.
5. DOMINATOR Stone Sealer 5 Gal – Wet Look Low Gloss Natural Enhancer for Outdoor Patio, Travertine, Flagstone, Limestone, — The natural-stone look with less shine
DOMINATOR Stone Sealer 5 Gal is the most restrained choice here for a bluestone patio because it’s framed as a wet-look low-gloss natural enhancer. That matters if your stone has blue-gray, charcoal, or rust veining you want to deepen without turning the patio into a mirror. The 5 gal size fits larger patios and porous stone surfaces. Rating is unavailable, so surface prep and small-area assessment matter. This is the finish I’d choose for older homes, shaded gardens, and less glossy hardscapes.

Buying Guide: What Matters for a Bluestone Patio
Start with finish, because you’ll see that choice every day. High gloss deepens color and adds visual drama, but it can look too slick on rustic bluestone. Low gloss keeps more of the natural cleft texture visible. For freeze-thaw regions, ASTM durability concepts are useful because water intrusion, UV exposure, and abrasion all affect how coatings age. Don’t seal trapped moisture. After rain, give stone at least 24 to 48 hours of dry weather before application, and follow the manufacturer’s temperature range.
Coverage is the next hard number. Porous bluestone may drink more sealer than dense pavers, so a 5 gal pail can be smarter for 500 sq ft than trying to stretch a smaller container. Joint condition matters too. If sand movement is the problem, a sand-lock formula has a direct consequence: less washout after storms. If color fade is the problem, choose the finish first. BIFMA doesn’t govern patios, but its furniture durability mindset is useful: surfaces, chairs, and cleaners interact every week.
High Gloss vs Low Gloss for Bluestone
High gloss is the sharper visual upgrade. It makes blue-gray stone read darker, wet, and more finished, especially around black metal furniture or a modern fire table. The trade-off is reflectivity. In bright sun, a high-gloss bluestone patio can show streaks, roller overlap, and dirt faster than a low-gloss finish. It’s not subtle.
Low gloss is more forgiving. It still enriches color, but the surface stays closer to natural stone. That’s better for irregular flagging, shaded garden patios, and older masonry. GREENGUARD and FSC are indoor and sourcing references, not patio-sealer standards, so don’t use those labels as substitutes for outdoor surface compatibility. For bluestone, manufacturer material fit and weathering language matter more.
Frequently Asked Questions
Should I seal a bluestone patio?
Yes, if the patio absorbs water quickly, stains from leaves, or loses joint sand after storms. Sealer can reduce water uptake and deepen color. It won’t repair cracked stone, bad drainage, or a failing base, so fix those first.
Is high gloss too slippery for bluestone?
It can be, especially near pools, shaded steps, or moss-prone areas. Check the manufacturer’s application guidance and avoid heavy over-application. Bluestone already has texture, but coating buildup can reduce grip on wet days.
How much sealer do I need for 500 sq ft?
Plan conservatively. Porous or cleft bluestone may need more product than smooth concrete pavers. A 5 gal container is usually the safer buying format for larger patios, borders, and second-coat planning.
Can I use paver sealer on natural bluestone?
Some paver sealers are suitable for stone, while others focus on concrete or brick. Read the product surface list before applying. For natural bluestone, a stone sealer or compatible water-based paver sealer is the safer category.
How often should a bluestone patio be resealed?
Many outdoor sealers are refreshed every 2 to 3 years, but sun exposure, traffic, drainage, and winter salt can shorten that cycle. Watch for fading color, faster absorption, and sand movement. Those are practical reset signals.
What prep matters most before sealing?
Clean stone, dry joints, and stable weather matter most. Remove dirt, algae, efflorescence, and old failing coating before you apply anything new. Sealing over moisture or debris can cause haze, blotches, or weak bonding.
Bottom Line
The Black Diamond Stoneworks GET SERIOUS Paver Sealer is my first pick for a bluestone patio because it targets the two problems homeowners actually notice: faded wet-look color and joint sand movement. DOMINATOR High Gloss 2.5 gal is the better condition-based pick for a smaller patio where shine is the goal and storage space is limited. The honest caveat: no sealer saves poor drainage, so surface prep and dry weather still decide the final result.
