Resin & Epoxy Mix Calculator

How much epoxy for a 24 x 48 table at 1/8 inch? How do you split it 2:1, or 100:45 by weight? How much 2-stroke oil goes in a gallon at 50:1? PourMix answers in fl oz, cups, quarts, gallons, ml, liters and grams, with the math shown. It works offline, with no account and no subscription. One small banner at the bottom, no pop-up ads.

EPOXY RESIN CALCULATOR
• Table top, river table, coating, round top or mold: length x width x depth, diameter x depth, or the volume you already know.
• River table: only the share of the area that is resin.
• A set of pieces: 4 coasters, 6 molds, with the amount for each piece.
• Deep pours: enter the max layer depth from the data sheet and get how many pours and how much each.
• Extra for waste and the mixing cup (10% by default).
• Part A and Part B for 1:1, 2:1, 3:1 or any ratio, plus the weight with the resin's density.
• How many kits of your size to buy, and the resin cost of the pour and of each piece from your kit price.
• Pigment amount in grams from a percent of the mix, and color swatches that tint the drawing.

RESIN MIX RATIO BY WEIGHT OR VOLUME
• Split any batch into Part A and Part B by volume or by weight (100:45, 100:30 and more).
• Turn a weight ratio into a volume ratio with the two densities from the data sheet, and back.
• Already poured some Part A? Get the Part B that goes with it.

2 STROKE FUEL MIX CALCULATOR
• Oil for your gas at 50:1, 40:1, 32:1, 25:1, 20:1 or any ratio, in fl oz, ml, tablespoons and teaspoons.
• Gas for the oil you have: a 2.6 fl oz bottle at 50:1 is about 1 gallon.
• US gallons or liters.

MIX RATIO AND DILUTION CALCULATOR
• Any A:B mix: 1:10 cleaner, 4:1 paint and hardener, concentrate and water.
• From the total you want, or from the concentrate you have.

CHARTS
• Epoxy coverage chart: common table sizes from 12 x 12 to 48 x 96 in, at 1/16 to 1/2 inch deep (and metric sizes).
• 2-stroke mix chart: oil for 1, 2, 2.5, 3 and 5 gallons and for 1 to 20 liters.

BUILT FOR THE SHOP
• Inches with fractions, or cm and mm. Type 1/8, 3/4", 6 mm or 2 gal in any field.
• Every tool opens with a worked example so you see the answer right away.
• History of your calculations. Share any result as text.
• Dark and high-contrast themes, big keypad option, keep the screen on.
• English and Spanish.
• No account. Nothing leaves your phone. Works without signal.

WHY CLEAN SCREEN APPS: I got tired of apps that throw full-screen ads at you in the middle of a job, so I build apps with no pop-up ads. PourMix is another one: one small banner at the bottom, never over your numbers, and a one-time "Remove ads" option. No subscription, ever.

Amounts and ratios are estimates. Follow your resin's technical data sheet and your engine's manual. Work with epoxy in a ventilated space with gloves and eye protection.
