# Professional Epoxy vs DIY Garage Floor Kits

> Hardware-store kits are 1-part epoxy with acid-etch prep. Pro systems are 2-part epoxy on diamond-ground concrete. Different floors, different lifespans.

 are not the same product at smaller scale. They’re different chemistries, with different prep, that produce different floors.

DIY kits are typically a single-part epoxy thinned for roller application. The “prep” is acid etching — pour, scrub, rinse. The kit goes down in an afternoon. It looks great for a year, sometimes two. Then Texas heat and tire pressure start lifting it.

## Why pro systems last 10x longer

A professional system uses 100% solids two-part epoxy that cures harder, bonds stronger, and resists heat. The prep is diamond grinding to a CSP 2-3 profile — a mechanical bond instead of a chemical one. Cracks are repaired with polymer-modified patch material. Moisture testing is run on slabs that need it.

The result is a floor that survives Texas summer after Texas summer. We’ve installed pro systems that are still showroom-clean 15+ years in. We haven’t seen a DIY kit make it that long.

If budget is the issue, do a smaller area in pro — a single bay, say — and add to it later. A DIY whole-garage kit you have to redo in 2 years is more expensive than half a pro garage you keep forever.

## Frequently Asked Questions

Do DIY kits ever work? +

On a brand-new slab in a climate-controlled, light-traffic garage they last a few years. In Texas garages with heat and tires they typically don't make it past summer two.

What's the actual chemistry difference? +

Pro systems use two-part epoxy with industrial fillers and a real primer. DIY kits are usually a single-part product cut with solvents to thin it for roller application.

Can I prep right and still use a DIY kit? +

Better prep helps any coating. But you still have the single-part product issue — it cures softer and lifts under heat.
