Guides: the method behind the numbers
Fix floor problems
- Why Is My Epoxy Floor Bubbling?
Moisture vapor from the slab or trapped air: how to tell which, and how to fix it.
- Why Is My Epoxy or Flake Floor Peeling?
Peeling almost always means the bond never formed. Usually prep, not product.
- Why Is My Epoxy Floor Turning Yellow?
Where the amber tint shows up tells you whether it is UV, blush, or age.
- Why Is My Epoxy Floor Blushing or Turning White?
That milky film is amine blush, not a mixing mistake.

Built for the coatings trade, not general construction
Trade Epoxy is 35 free calculators built for epoxy and concrete coating contractors. Every tool runs in your browser with no signup and no paywall, on site or in the office.
These are not generic construction calculators. Each one works the way a coatings job actually runs. Material tools size base coat, broadcast, and topcoat as separate layers with their own coverage rates, in gallons or liters. Prep tools cover grinding production rates by pass, crack filler, and moisture vapor barriers. Pricing tools build a sell price the way an established contractor does: labor, materials, overheads, equipment wear, vehicle cost, and the profit margin you actually keep.
When you want the method behind the math, the guides above explain it, and every guide links to the calculator that does the work.
