Epoxy & Concrete Coatings in St. George, Utah

Epoxy and concrete coating installers in St. George — garage and patio floors, and why ultraviolet exposure rules out some products here.

Not all coatings survive this sun

Standard epoxy is an excellent garage floor coating and a poor choice for anywhere sunlight reaches it. Epoxy ambers under ultraviolet exposure — it yellows, and it can chalk and lose gloss. In a region with sun as intense as this one, that is not a marginal concern.

Polyaspartic and polyurea coatings are considerably more ultraviolet-stable, which is why they dominate the outdoor and part-sun work here, and why many local installers use an epoxy base coat with a polyaspartic topcoat rather than epoxy alone. If a quote is for epoxy on a patio, a pool deck or a garage that takes direct sun through an open door for hours a day, ask specifically about ultraviolet stability.

Heat and hot tire pickup

Garages in this climate get very hot. Two things follow. First, some coatings are more prone to softening at high surface temperature. Second, hot tire pickup — where a hot tire bonds to the coating and lifts it when the car moves — is a genuine failure mode, and it is much more likely with thin or poorly bonded coatings. Ask what the installer is doing about it.

Preparation is the whole job

Coating failures are almost always adhesion failures, and adhesion is determined before any coating is applied. Mechanical preparation — grinding or shot blasting rather than acid etching — is what a durable installation depends on. Moisture in the slab is the other common cause of failure, and a moisture test is worth asking about on any slab where it is in question.

Questions worth asking

  • What system, and how many coats? "Epoxy floor" describes a range of products with very different lifespans.
  • How is the slab being prepared?
  • What is the cure time before the floor can take foot traffic and vehicle traffic?
  • What does the warranty exclude? Hot tire pickup and ultraviolet discolouration are common exclusions.

Frequently asked questions

Will an epoxy floor turn yellow in the sun here?

Standard epoxy does amber under ultraviolet exposure, and sun in this region is intense enough to make that a real consideration wherever light reaches the floor — a patio, a pool deck, or a garage that stands open in the afternoon. Polyaspartic and polyurea coatings are substantially more ultraviolet-stable, and many local installations use an epoxy base with a polyaspartic topcoat for that reason. If sunlight will reach the surface, ask specifically what the topcoat is rather than accepting 'epoxy' as the description.

What is hot tire pickup?

It is a failure where a hot tire bonds to the floor coating and pulls it off the slab when the vehicle moves, leaving patches in the shape of the contact area. Garages in this climate get very hot and tires come off summer roads hotter still, so it is a genuine risk locally rather than a theoretical one. Good surface preparation, an appropriate system and adequate cure time before parking on it all reduce the risk. Ask whether the warranty covers it, because it is frequently excluded.

Why do some coated floors peel?

Almost always because the coating never bonded properly, and that is decided during preparation rather than during application. A slab that was acid-etched instead of mechanically ground, or that was contaminated with oil, or that had moisture moving up through it, will not hold a coating no matter how good the product is. Ask how the installer prepares the surface — grinding or shot blasting is the answer you want — and whether they test for moisture where there is any doubt.
