Pourwell: Resin Calculator

Pourwell works out how much resin and hardener to mix for your mould, so you don't run out halfway through a pour or throw away half a cup.

Pick the mould shape, type its size, and the amounts appear as you type. A drawing of the shape numbers every measurement, so you always know which line is which.

MOULD SHAPES
• Box, round (coasters, cylinders), ring, dome and triangle
• River table: subtract the wood, or say how much of the mould the resin fills
• Custom volume, when you already know it
• Millimetres, centimetres or inches; ml or US fl oz

MIX IT RIGHT
• Any ratio printed on your kit: 1:1, 2:1, 100:45 …
• By volume or by weight. Part A and part B are shown in ml and in grams (fl oz and oz in imperial)
• Resin density you can change (1.1 g/ml to start)
• An extra for spills and what sticks to the cup, 10% unless you change it

LAYERS
Pouring in stages? Add up to 20 layers, each with its own depth, and see the amount for every layer. A dome is worked out layer by layer from its lowest point.

PIGMENT AND COST
• Pigment as a percentage of the mix, in grams and ml
• Enter what your resin costs per kg, per litre or per US gallon to see the cost of the pour and of each piece. Handy when you price coasters for a craft fair.

POUR LOG AND DEMOLD TIMER
Save a pour with a name and notes: brand, colours, which mould. Open it again later to repeat it or change it. Start a demold timer (12, 24, 48 or 72 hours, or your own) and get one reminder when it is done. Notification permission is asked for only when you start a timer.

EASY ON THE EYES
Clean screens, large buttons, light and dark themes. In 12 languages.

NOTHING LEAVES YOUR PHONE
Every number is worked out on the device. No account, no sign-in, and it works with no connection at all. Your pour log stays on your phone.

ADS
Pourwell shows one small banner, and at most one full-screen ad every four minutes, only right after you save a pour, never while you type. A one-time purchase removes all ads. Nothing else is locked.

Always follow the mixing and safety instructions for your resin.
