Promise Epoxy Specs — Coverage Rates, Mix Ratios & Prices
Promise Epoxy epoxy products compared: published coverage rates, mix ratios, thickness caps, recoat windows and official prices — every figure cited with a Last Verified date.
Quick answer
Promise Epoxy sells 2 epoxy products — none with a published coverage chart. Formerly ProMarine Supplies — rebranded to Promise Epoxy (301-verified domain move). Every figure below traces to an official Promise Epoxy source; anything unpublished is marked rather than estimated.
Manufacturer datasheet · 2026-11-06Promise Epoxy publishes no coverage chart — a fact we state rather than paper over. Where a brand omits the number, this site applies the labeled theoretical baseline (the 1604 rule) instead of inventing one, and the spec tables below carry everything the brand does publish: mix ratios, thickness caps, recoat windows and prices, each with its source.
Promise Epoxy Promise Table Top Epoxy Resin
Coverage: Promise publishes no sq-ft-per-gallon figure anywhere on the product page, FAQ or TDS — every coverage question points to their on-site JS calculator. This site falls back to the 100%-solids theoretical rate (12.8 sq ft/gal at 1/8"), clearly labeled as theoretical.
Specs (official sources):
| Spec | Value |
|---|---|
| Mix ratio | 1:1 by volume — By weight it is 100 A to 83 B — the official FAQ says never weigh the sides for this product, measure by volume. |
| Solids content | 100% (single) |
| Recommended coat | 0.125" |
| Recoat window | 4–5 hours (recoat when first layer is firm but tacky; after full cure, scuff with 320-grit first) |
| Cure profile | Tack free 4–5 h; work time 30–45 min (100 g mass); full cure 72 h per product page, up to 5 days per TDS; Shore D81; heat tolerance 130 °F |
| Price | $61.19 per 1 gal kit ($61.19/gal) — current sale price, Shopify official product JSON + product page cross-checked (dual) |
| Typical uses | tabletops, bars, wood finishes, see-through encapsulations, artwork |
Promise Epoxy Promise Deep Pour Epoxy Resin

Specs (official sources):
| Spec | Value |
|---|---|

How to read these tables
Three habits make spec sheets comparable instead of confusing. First, read the coverage rows before the price rows: a cheaper per-gallon price on a product that covers less ground can be the more expensive pour, and the calculator above is the honest tiebreaker. Second, treat the thickness caps as hard limits, not suggestions — a coating product pushed into casting depth fails from the inside out, by heat, hours after the pour looked fine. Third, check the recoat window against your actual schedule: a 3-hour window means the second coat goes on the same afternoon or not at all without sanding, and a day-long deep-pour window means a weekend, not an evening. Every value above keeps its source and verification mark so those trade-offs can be argued with data — and where a row reads "(to be verified)", it means the brand does not publish the figure, not that we skipped it.
FAQ
What coverage does Promise Epoxy publish?
Promise Epoxy publishes no sq-ft-per-gallon chart; this site applies the labeled 1604-rule theoretical baseline to its products instead of an invented number. The [coverage calculator](/epoxy-coverage-calculator) switches rates automatically when you pick a Promise Epoxy product.
Where do these Promise Epoxy specifications come from?
Every figure is captured from Promise Epoxy's own published material — official product pages, TDS documents and help-center articles — with the source link shown under each table and a Last Verified date (2026-11-06). Where the same figure appears on two official pages it is marked dual-verified.
Is Promise Epoxy the best epoxy for my project?
Size the project first — area and thickness through the [coverage calculator](/epoxy-coverage-calculator) — then compare candidates on the specs that matter for your job: max coat thickness for builds, recoat window for schedules, and the price per gallon from the [cost calculator](/epoxy-cost-calculator). "Best" without a project is marketing.
