Sealed concrete in Texas

Sealed concrete in Texas, from Wichita Falls to Texarkana

Sealed concrete in Texas runs $1.31 to $3.42 a square foot with us, installed. That covers the four sealers in our quote tool. We price polyaspartic and strip-and-reseal work per job, after we see the floor. Three things pick your sealer. Near Wichita Falls, it’s sulfate in the ground. In North Texas, it’s damp sand under the slab. Everywhere, it’s a sun that hits UV index 10 or higher. Every job carries our 1-year workmanship warranty on installation defects.

Our sealed concrete page covers the service everywhere we work. The Texas concrete flooring hub covers the rest of the state.

We work three parts of Texas. The Texarkana area covers Bowie County on the Texas side. North Texas covers Collin, Grayson, and Fannin counties: Plano, Frisco, McKinney, Allen, Sherman, Denison, Bonham, and Paris. Wichita Falls anchors Wichita County to the northwest. The ground is different in each one, and so is the sealer a slab there can hold. The rock and sand your ready-mix plant draws from matters too. Near Texarkana, slabs sit on Annona Chalk and read denser at the top. Near Wichita Falls, gypsum in the red rock brings sulfate, and that rules out most film sealers. On the edge of the Dallas-Fort Worth area, slabs on Trinity Sand and Eagle Ford Shale push up a lot of moisture. Those slabs often show the warning signs that call for a moisture test before we write a plan.

A quick way to pick your sealer

• Slab near Wichita Falls with sulfate damage? Use a silane or siloxane that soaks in. A film sealer will peel there.
• Want a harder, dust-free floor with no change in shine? Use a silicate densifier.
• Home garage or basement floor, indoors, on a budget? Acrylic works. Plan to reseal every 2 to 4 years.
• Busy commercial floor in North Texas? Use polyurethane.
• Concrete out in direct sun? Use polyaspartic.
• Forklift fluids or plant chemicals on the floor? Use an epoxy topcoat.
• Old coating peeling? It has to come off first. We grind down to clean concrete, then seal.

Which sealed concrete systems does Bel Covo install in Texas?

Most Texas jobs use one of six sealers. Three things decide which: sulfate in the ground, moisture coming up through the slab, and whether the floor sits indoors or in the sun.

• Penetrating silicate densifier. A liquid silicate (sodium, potassium, or lithium) that reacts with the free lime in the cement. It hardens the top 1/8 inch of the slab. There’s no film, no change in shine, and no recoat schedule. It’s our default on Wichita Falls slabs at risk from sulfate.
• Silane and siloxane water repellents. These soak into the pores and shed water without leaving a film on top (per ASTM D1331). We use them outdoors where slabs freeze and thaw. We also use them on sulfate-damaged slabs near Wichita Falls, where film sealers fail.
• Acrylic. A water-based or solvent-based film for home and light commercial floors indoors. It has a light shine, costs less, and needs a reseal every 2 to 4 years. It’s common on North Texas garage and basement floors.
• Polyurethane. A two-part film for commercial floors that take hard wear and chemicals. We use the aliphatic kind, the kind that won’t turn yellow in the sun. It’s our standard pick for busy commercial floors in North Texas and for military maintenance bays.
• Polyaspartic. A fast-curing polyurea that holds up to sun and wear. It’s our first call for any sealer that sits outdoors in Texas. At UV index 10 and up, a film that isn’t aliphatic breaks down within five years.
• Epoxy topcoat. A thick epoxy build for warehouse, distribution, and plant floors, where forklift fluids or process chemicals set the plan.

Sealing often goes with other work. We pair it with garage floor coatings, a cove base where the floor meets the wall, and concrete flatwork walks and patios.

How do Texas climate and substrate shape sealed concrete?

Our part of Texas has three kinds of ground under the slab (the substrate), plus one harsh sun. Each one changes the sealer before we ever pick a product.

Sulfate near Wichita Falls. The red rock under Wichita County (Permian red beds) holds gypsum, and the groundwater carries sulfate. Sulfate reacts with the cement and grows new crystals, ettringite and gypsum. They swell and crack the slab from the inside. New pours there need Type V cement (ASTM C150 Type V), the kind made to resist sulfate, so the slab can last past 30 years. Old slabs with sulfate damage can’t hold an acrylic or polyurethane film. Moisture moves through the damaged concrete and lifts the film in two to four years. A silane or siloxane that soaks in (per ASTM D1331) is the only safe cover for those slabs. So the sulfate test comes before we pick a sealer.

Chalk near Texarkana, sand in North Texas. On the Texas side of the Bowie County line, slabs sit on Annona Chalk. It’s a Cretaceous chalk layer that makes the top of a slab denser, and it changes how long we prep. Plano, Frisco, McKinney, and Allen sit on Trinity Sand and Eagle Ford Shale. Both push more moisture than most up through slabs poured on the ground. If a North Texas slab shows a warning sign, or you ask, we test before we quote a film sealer. We run a calcium chloride test (ASTM F1869) and a probe that reads the damp inside the slab (ASTM F2170). A wet slab needs a densifier, or an epoxy primer made for moisture, before any topcoat.

The Texas sun. Our whole Texas area hits UV index 10 or higher from May through September. In direct sun, two films break down in three to five years. One is acrylic with no UV blocker. The other is aromatic polyurethane, the kind that yellows. Polyaspartic is aliphatic, so it holds its color past 10 years. That makes it our first pick outdoors. Indoors, the sun matters less, and the ground under the slab matters more.

What sealed concrete project types does Bel Covo run across Texas?

Texas sealing work falls into five kinds of jobs. Each one has its own ground problems, sealer, and price across North Texas, Wichita Falls, and Texarkana.

Corporate campus flatwork in Plano and Frisco

The office campuses across Collin County bring the most business sealing work in our Texas area. Office parks and big warehouses there need sealer on parking decks, warehouse floors, loading docks, and outdoor flatwork. A typical job runs 5,000 to 50,000 SF. It’s almost always polyurethane inside and polyaspartic outside. Heavy traffic and the UV index 10+ summers both wear out acrylic too fast.

How do military facilities use sealed concrete?

Military sites around Wichita Falls and Texarkana lean on polyurethane and polyaspartic. That means hangar floors, vehicle maintenance bays, and storage warehouses. Tracked vehicles grind at the surface. Hydraulic fluid and jet fuel attack it. And the building has to get back in use fast, which the quick cure of polyaspartic allows. A typical building runs 2,000 to 20,000 SF. Our check of the old slab covers moisture, sulfate on the Wichita Falls side, and how rough the grind needs to leave it.

Semiconductor-adjacent floors in Sherman and Denison

Semiconductor plants around Sherman and Denison, and the wider growth of chipmaking in North Texas, bring floors that sit next to cleanrooms. They aren’t full ISO-class cleanrooms. They’re the halls, gowning rooms, and warehouse space around them. These floors need polyurethane or epoxy with written proof of how much moisture gets through. When the spec asks for that proof, we test more than we would on a house. We run the in-slab probe (ASTM F2170) and a pull-off bond test (ASTM C1583) before we choose the system.

Which Texarkana commercial buildings need re-seal work?

Warehouse, retail, and light industrial floors on the Texas side of the Bowie County line get resealed every five to ten years. Re-seals make up most commercial sealing work around Texarkana. We diamond grind the failed coating off to CSP 2 to 4. When the slab check calls for it, we run a moisture test (ASTM F1869). Then the new system goes down. We price a re-seal per job, once we see how the old coating failed and pick what replaces it. Annona Chalk reads denser on top than most Texas concrete, so it changes how long we grind.

How does residential garage work scale across Collin County?

Plano, Frisco, McKinney, Allen, and the rest of the Collin County suburbs bring steady garage floor sealing work. A typical job is a 400 to 800 SF garage. We check the slab and run a moisture test when the check shows a warning sign or you ask for one. Then comes an optional diamond grind, a polyaspartic or polyurethane topcoat, and a cove base where the floor meets the wall. Moisture is the most common holdup on Trinity Sand and Eagle Ford Shale lots, and a wet slab needs extra prep before the topcoat goes down.

How much does sealed concrete cost in Texas?

Your price depends on the sealer, the shape the slab is in, any old coating, and how hard the floor is to reach. These are our 2026 rates for jobs across Texarkana, North Texas, and Wichita Falls, inside and out.

Each rate covers cleaning, prep, and putting the sealer down. The table shows the sealer alone. The range at the top of the page also adds our setup, plus extras like heavy degreasing for an oil-soaked slab, so it runs higher. We price polyaspartic after we see how much sun the concrete gets. We price a re-seal after we see what the old coating is and how it failed.

These things move your number:

• An old coating, or sulfate damage in the slab
• Moisture coming up through the slab
• Sulfate in the ground
• How long you need the sealer to last
• How hard the floor is to reach

The sealed concrete cost guide breaks it down by job and sealer. Every quote lists the drive cost (our trip from our home shop to your site) on its own line, so you see it up front.

Which Texas cities does Bel Covo serve for sealed concrete?

We seal concrete in three parts of Texas. That’s the Texarkana area, North Texas through Collin and Grayson counties, and Wichita Falls to the northwest.

• Texarkana and Bowie County on the Texas side
• Sherman and Denison in the Grayson County plant belt
• Plano, Frisco, and McKinney along the Collin County office corridor
• Wichita Falls and the rest of Wichita County
• Paris, Bonham, and the farm towns of Lamar and Fannin counties

We look at jobs outside these areas when you ask. Every sealed concrete quote shows the drive cost from our home shop on its own line, so you see it before you commit.
