Epoxy vs Polyaspartic

The two options buyers compare most in this category solve the same problem at different price points and with different failure modes. The honest comparison is cost per year of service, not sticker price.

What the comparison hides

Two traps. First, comparing a premium material installed without prep against a mid-range material installed properly — the cheap install fails first. Second, comparing a five-year cost for one option with an installed price for the other. Normalise both to cost per year before deciding.

The cost hub has the line items, the methods hub explains the failure modes, and the contractor hub covers how to read the quote.

Is the more expensive option worth it?

When the exposure is hard on the cheaper material, or when re-doing the job would cost more than the difference. Otherwise no.

Can the two be combined?

Sometimes — a premium surface over a repaired base is a common compromise. Ask what warranty covers the combination.
