Concrete Coatings in Texas
Concrete coatings is a broader category than a single floor product. A project may involve a penetrating sealer, decorative finish, protective film, or resinous coating on an interior floor, exterior slab, wall, patio, walkway, loading area, or other site concrete. The correct system follows the substrate and exposure rather than the name of the surface alone.
Overview: Concrete Coatings
Concrete coatings is a broader category than a single floor product. A project may involve a penetrating sealer, decorative finish, protective film, or resinous coating on an interior floor, exterior slab, wall, patio, walkway, loading area, or other site concrete. The correct system follows the substrate and exposure rather than the name of the surface alone.
Planning Concrete Coatings
Concrete coatings is a broader category than a single floor product. A project may involve a penetrating sealer, decorative finish, protective film, or resinous coating on an interior floor, exterior slab, wall, patio, walkway, loading area, or other site concrete. The correct system follows the substrate and exposure rather than the name of the surface alone.
Coating, sealer, or decorative treatment?
A sealer may penetrate or form a relatively thin protective film, while a coating generally creates a more defined surface layer. Decorative stains, dyes, clear finishes, acrylic systems, epoxy, polyurethane, polyaspartic, or other specialty systems may be appropriate in different situations. The distinction is not absolute across manufacturers, so the proposal should identify the actual product category, number of layers, finish, and maintenance expectations.
Interior and exterior applications
Interior floors may be evaluated for foot traffic, carts, forklifts, cleaning chemicals, appearance, and downtime. Exterior slabs and site concrete add UV, rain, drainage, thermal movement, freeze-thaw exposure in some areas, and weather windows. Walls, patios, walkways, loading docks, and commercial surfaces each have different access and masking needs. A system suitable for a covered interior may not be suitable for an exposed slab.
Assessing existing concrete
New and existing concrete should be checked for curing, porosity, laitance, dusting, cracks, spalling, contamination, moisture, prior sealers, and surface profile. Repairs and preparation may include mechanical methods selected by the contractor, localized patching, and removal of incompatible films. Coating does not make structural cracking or active moisture problems disappear; those conditions need to be identified in the scope.
Exposure, pricing, and maintenance
Traffic, UV, water, chemicals, desired appearance, cleaning methods, and maintenance access all influence material selection. Pricing also depends on area, substrate condition, repairs, preparation, system build, decorative finish, interior or exterior access, masking, and scheduling. Ask how the proposed system is expected to weather, how it is cleaned, and what future touch-up or recoating work may involve without treating a generic product label as a performance guarantee.
What to Send With Your Request
- interior or exterior location and concrete type
- approximate area, access conditions, and exposure to traffic or weather
- photos of porosity, cracks, spalling, stains, and previous sealer
- desired appearance, sheen, color, cleaning routine, and timing
Questions to Ask a Contractor
- Is the recommendation a sealer, coating, or a layered system, and why?
- How will the contractor verify moisture, profile, and compatibility?
- Which repairs, masking, protection, and maintenance steps are included?
How Contractor Matching Works
- 1. Submit the location, scope, surface condition, photos, and timing.
- 2. Painters of Texas reviews the request for service type, project fit, and contractor availability.
- 3. Participating independent contractors may receive the opportunity and decide whether to respond.
- 4. Review any contractor responses, credentials, scope, and pricing before deciding whether to proceed.

Concrete Coatings — Frequently Asked Questions
What type of coating works on concrete?
The answer depends on interior or exterior exposure, traffic, moisture, UV, appearance, chemical contact, and maintenance. A contractor may recommend a sealer, acrylic, epoxy, polyurethane, polyaspartic, or another compatible system after inspecting the slab.
Can old concrete be coated?
Often, but age is less important than condition. Existing contamination, weak concrete, cracks, moisture, and old films must be assessed and prepared before a system is selected.
Can exterior concrete be coated?
Some exterior slabs can receive protective or decorative systems. Drainage, weather, UV, surface profile, moisture, and pedestrian or vehicle use must be considered before choosing a product.
Will a coating hide cracks?
A finish may visually reduce minor surface imperfections, but it does not resolve structural movement. Cracks should be documented and repaired or left as a deliberate maintenance joint according to the project conditions.
What is the difference between a concrete coating and sealer?
A sealer is commonly thinner or penetrating, while a coating generally forms a more defined film. Product definitions vary, so the proposal should describe the actual system and intended exposure.
What affects concrete-coating cost?
Area, access, condition, repairs, preparation, interior or exterior exposure, system build, decorative finish, masking, and schedule all influence a contractor’s proposal. Exact pricing requires project details.
