Outdoor living, elevated.

Can you put epoxy on an outdoor patio?

Yes, with one important caveat: not plain epoxy. Epoxy on its own is not UV-stable. Left exposed to the sun it ambers, chalks, and eventually breaks down at the surface. That is why so many DIY patio coatings look tired within a year. The system that works outdoors is the same one we use in garages: an epoxy base coat for the bond to the concrete, a full flake broadcast for texture and color, and a clear polyaspartic topcoat on top. Polyaspartic is what makes the floor sun-proof. It does not yellow, it does not chalk, and it holds its gloss through a Texas summer.

So when you search for an epoxy patio floor or a concrete patio coating, what you actually want is a flake system finished in polyaspartic. That is what we install on every patio, porch, and outdoor kitchen floor.

Why a coated patio beats stained or bare concrete

Most patios in our area are either bare broom-finished concrete or an acid stain that has faded unevenly. Both have the same problems: they absorb everything, they are hard to clean, and they crack and spall as the slab moves. A flake coating solves all three at once.

• Seamless and non-porous. Rain, mud, grill grease, and spilled drinks sit on the surface and rinse off with a hose instead of soaking in.
• Slip-resistant. The flake texture adds grip when the patio is wet, which matters around outdoor kitchens and covered porches where people walk barefoot.
• Cooler underfoot. Lighter flake blends reflect heat rather than absorbing it the way dark stained concrete does.
• Hides the slab. Discoloration, old stain, patched areas, and minor pitting disappear under a full flake broadcast.
• Matches the house. Twelve standard blends, from stone greys to warm tans, so the patio floor ties into brick, siding, and pavers instead of fighting them.

How we prep an outdoor slab

Outdoor concrete is harder to coat than a garage floor because it has been exposed to weather, and often to years of sealers, stains, and pressure-washing. We mechanically diamond-grind every patio to remove whatever is on the surface and open the pores of the concrete. Old acid stain, clear sealers, and the weak top layer of the slab all come off in that step.

Cracks are chased and filled. Spalled or pitted spots are skim-coated flat. Expansion joints are cleaned out and either honored in the finish or filled with a flexible joint compound, depending on the slab. Then the moisture-tolerant epoxy base goes down, which matters even more outside because ground moisture moves through an exterior slab constantly. The flake broadcast and polyaspartic topcoat follow.

Weather affects outdoor scheduling more than it affects garage work. We will not coat a patio in the rain or when temperatures and humidity are outside the working range of the materials. We will tell you what to expect and we will show up when we say we will.

Where a patio coating makes sense, and where it does not

Covered patios and back porches are the ideal application. The roof protects the floor from the worst of the sun and standing water, and the coating turns the space into a true outdoor room. Outdoor kitchens are a close second, because the seamless surface is so much easier to keep clean around a grill. Uncovered patios work well too as long as the concrete is sound and drains properly.

Where we say no: slabs with active structural cracks that are still moving, slabs that hold standing water, and slabs so badly deteriorated that grinding would not leave a solid surface behind. If your patio is in that condition, we will tell you at the estimate rather than coat it and have it fail.

The before-and-after above is one of our own projects: a covered patio and outdoor kitchen with a stained, patchy red concrete floor. After grinding, crack repair, and a full grey flake broadcast under a polyaspartic topcoat, the floor is seamless, uniform, and slip-resistant, and it finally matches the slate bar and brick behind it. That is the difference between a patio you tolerate and one you want to sit on.

Patio coating pricing

Patios are priced the same way as garages: by square footage and by the condition of the concrete. Our project minimum is $1,400, and a typical covered patio lands in the same range as a two-car garage. The Pricing page explains what moves the number. If you are doing a garage and a patio together, tell us. Same-visit projects are simpler for us to schedule and we can price them accordingly.

Patio coating vs. pavers, stamped concrete, and tile

Homeowners weighing a patio coating usually compare it against three alternatives. Pavers look great but sit on a sand bed that shifts, grows weeds in the joints, and needs periodic re-leveling. Stamped concrete is a new pour, which means demolition of the existing slab and a much larger budget, and the color release on stamped concrete fades and needs resealing. Outdoor tile is expensive, the grout stains, and tile over an existing slab that moves will crack along with it.

A flake coating works with the slab you already have. There is no demolition, no new concrete, no grout, and no joints for weeds. The cost is a fraction of a new pour, and because the finish is seamless there is nothing to re-sand, re-seal, or re-level later. For a patio that is structurally sound but ugly, it is almost always the highest-value option.

Design ideas: matching the patio to the house

The most common mistake we see in outdoor flooring is picking a color in isolation. A patio floor sits next to brick, siding, stone, and whatever the pool deck or walkway is made of, and the blend should tie those together rather than add another competing color.

Caring for a coated patio

A polyaspartic patio floor is about as low-maintenance as an outdoor surface gets. Hose it off when it gets dirty. Use a broom or a leaf blower for leaves and grit, since grit is the one thing that will dull any finish over time if it is ground underfoot for years. A mild soap and a soft brush handle grill grease and mildew in shaded corners. No sealing, no resealing, no re-sanding of joints, and no pressure-washing required, although pressure-washing will not hurt it.

Furniture with hard plastic or metal feet can be dragged across the floor without scratching the topcoat, but felt or rubber pads under heavy pieces are still a good idea for the same reason they are on any floor.
