DIY vs Professional Epoxy in Denver, CO
The kit is not the variable. Preparation is.
| Factor | Option A | Option B |
|---|---|---|
| Cost up front | $60 to $160 for a retail kit | $1,800 to $5,500 for a two-car garage |
| Dry film thickness | 2 to 5 mils | 20 to 35 mils on a double broadcast |
| Prep | Usually acid etch or nothing | Diamond grind to CSP 3-4, moisture tested |
| Life expectancy | Often fails inside 24 months | 12 to 15+ years before a topcoat refresh |
| Moisture handling | No mitigation | Vapour barrier system where readings demand it |
| Denver note | Cold slabs and de-icing salt expose thin films quickly | Same prep standard whatever system is chosen |
Why kits fail here.
A retail kit assumes a dry, flat, sound slab and gives you a thin film. Denver-series clay holds water, freeze-thaw moves the slab, and salt gets tracked in. A 2 to 5 mil film has little to give.
What the money buys.
Grinding equipment, moisture testing, patching, a built film and a warranty. It buys the conditions a coating needs to stay bonded.
