Epoxy Brands Compared — Coverage, Mix Ratios & Prices Side by Side
Eight epoxy brands, one neutral table: published coverage, mix ratios, max pour depths, recoat windows and official prices — every figure cited to official pages.
Quick answer
Eight brands, fourteen products, one comparison. The published coverage range runs from TotalBoat's 12.8 sq ft/gal tabletop standard to West System's ~292 sq ft/gal marine saturation coats; mix ratios split into 1:1 tabletop systems and 2:1 deep pours, with KSResin's 1:1 deep pour and West System's 5:1 marine system as the outliers. Every number below was captured from official sources on 2026-11-06/07 — the brand pages carry the line-by-line citations.

What the table says
Three data-honesty tiers emerge on their own: brands that publish real charts (TotalBoat, Primaloc), brands that publish calculator formulas we can quote and convert (Stone Coat, KSResin coating line, Upstart), and brands that publish nothing usable (Promise's coverage sections defer to their JS calculator). This site's promise is that the tier each brand lands in is visible — nothing here flatters a missing number.
The 2:1 deep-pour club — TotalBoat Fathom, Primaloc Deep Pour, Upstart Deep Pour, Stone Coat Ultra Deep, Promise Deep Pour — agrees on the fundamentals: 2-inch layers, day-long recoat windows, volume math. The differences are in the caps' fine print (small-mold exceptions, added-layer limits) and the recoat chemistry, which the river table page turns into a pour schedule.
The 1:1 tabletop field splits on thickness and schedule: TotalBoat's 3-hour no-sand window is the fastest recoat in the library; Primaloc publishes the highest flood rate; Promise is the price row (a Polytek-owned rebrand of ProMarine Supplies); Upstart's calculator is calibrated in public.
How to use this comparison
- Size your project at the coverage calculator — pick each candidate product in turn.
- Price the same job across all brands at the cost calculator.
- Check the spec that decides your job — pour depth for rivers, recoat window for weekend builds, UV claims for sunny rooms — on the brand page.
- Buy the kit size the calculator rounds to, from any source; the math on this site works regardless of where the resin ships from.
Verification discipline
Every figure carries three marks: dual (same value on two official pages), single (one official page), or derived (converted from the brand's own calculator or kit coverage, with the formula quoted). Prices are checkout-source JSON. Conflicts are kept visible — Primaloc's page-tag/checkout price gap and Promise's 48-hour-vs-7-day cure conflict are recorded as-is, because a comparison site that hides conflicts is just a quieter advertisement.
FAQ
Which epoxy brand covers the most per gallon?
Among published rates: Primaloc's flood coat covers 16 sq ft/gal at 1/8" — the highest dual-verified published rate in our library. TotalBoat TableTop publishes 12.8, matching the 100%-solids theory exactly. Stone Coat's calculator basis runs 20 sq ft/gal but without a stated thickness. Coverage alone doesn't pick a winner — price per gallon and kit sizes complete the math on the [cost calculator](/epoxy-cost-calculator).
Why do some brands show no coverage rate?
Because they don't publish one. Promise Epoxy's product pages, FAQ and TDS all defer to their website calculator without stating a rate; Stone Coat's Ultra Deep Pour and KSResin's Liquid Cast are volume casting resins with no area quotes. Rather than invent numbers, this site marks those rows honestly and applies the labeled theoretical baseline in the calculator.
Are these brands affiliated with this site?
No. Every spec here was captured from the manufacturer's own pages, TDS documents and help centers with a Last Verified date; where a page sits behind anti-bot protection, the figure was still read from that brand's official channel (archived snapshot of the official page, or the brand's own Shopify/Zendesk endpoints) — never from retailer listings or third-party claims.
