Frequently asked questions about epoxy resin calculation
How much epoxy resin do I need for a 120×60×4 cm river table?
For a river table with a 120×20×4 cm central channel you will need around 3.2 kg of mix, split into 2 layers of 2 cm with 18 h between each. The calculator gives you the exact result in seconds based on your measurements.
Why does epoxy resin need to be poured in layers?
Epoxy resin generates exothermic heat as it cures. If you exceed the max depth per layer (typically 2 cm), it can overheat, yellow or crack. Deep pour resins like Artline Wood PRO allow up to 6 cm per layer.
What is the A:B ratio in an epoxy resin?
It is the exact proportion between the resin (part A) and the hardener (part B) you need to mix. A 2:1 ratio means 2 parts resin per 1 part hardener. Getting the ratio wrong means the resin will not cure.
How long does epoxy resin take to cure?
Solid to touch in 24 h, workable in 3-5 days and fully cured in 7 days. For surfaces under heavy use, wait for the full cure before putting them to work.
Is this calculator free?
Yes, ResinCalc is 100% free and no sign-up is required. We earn revenue through affiliate links, at no extra cost to you.
What waste margin should I use?
We recommend 10% by default. It compensates for resin stuck in cups, stir sticks and gloves. If it is your first project, bump it up to 15% for safety.
Which resin should I pick for my project?
It depends on depth: for pieces under 1.5 cm use a coating resin (Artline Crystal or Honey), for 2-4 cm use a casting resin, and for 4 cm or more you need a deep pour (Artline Wood PRO). The calculator picks the best option automatically.
Does temperature affect curing?
Yes. Resin cures best between 20-25°C with humidity below 70%. Below 18°C curing slows down and defects can appear. Above 28°C pot life shortens.
How much epoxy resin do I need per square meter?
As a rule of thumb, count 1.1-1.2 kg of mix per m² for every millimeter of thickness: 1 mm ≈ 1.2 kg/m², 1.5 mm ≈ 1.6 kg/m² and 2 mm ≈ 2.2 kg/m². For floors multiply by the target thickness; for pieces with volume use the calculator.
What is the density of epoxy resin?
Most epoxy resins have a density between 1.05 and 1.20 g/ml. Artline resins range from 1.08 g/ml (Honey) to 1.12 g/ml (Crystal). ResinCalc uses each product's real density to convert volume into exact grams.
How the epoxy resin calculator works
Calculating how much epoxy resin you need is not just multiplying volume by density. There are technical factors that affect both the result and the safety of your project. Here is everything ResinCalc takes into account.
The basic formula
The amount of resin needed is calculated by multiplying the area of the piece by the depth and by the resin density. Epoxy resins have densities between 1.05 and 1.20 g/ml depending on the manufacturer. ResinCalc uses the real density of each Artline product, not an estimate.
Why depth is critical
Each resin has a max depth per layer. If you exceed it, the exothermic reaction releases too much heat: the resin yellows, cracks or fails to cure. Coating resins handle 1-2 cm per layer, casting resins 2-3 cm, and deep pour resins like Wood PRO up to 6 cm.
Pouring in layers
If your project exceeds the resin max depth, ResinCalc splits the pour into safe layers automatically. Between layers you need to wait 16 to 24 h so the previous one has gelled but is still reactive. Each layer has its exact mix amount.
A:B ratio and mixing
Epoxy resins are sold in two components: resin (part A) and hardener (part B). Each product has its exact ratio: 2:1, 3:1 or 1:1 are the most common. ResinCalc gives you the exact grams of each part so the mix is perfect and the resin cures as it should.
Quick reference tables
How much epoxy resin per square meter
Approximate amount of mixed resin (resin + hardener) to cover 1 m² of flat surface by layer thickness, before adding the waste margin.
| Layer thickness | Mix per m² | Typical use |
|---|---|---|
| 0.3 mm | ≈ 0.4 kg | Seal coat or thin layer |
| 1 mm | ≈ 1.2 kg | Varnish-like finish |
| 1.5 mm | ≈ 1.6 kg | Self-leveling mirror coat |
| 2 mm | ≈ 2.2 kg | Countertop or fluid art |
| 3 mm | ≈ 3.3 kg | Floor coating |
Rule of thumb: about 1.1-1.2 kg of mix per m² for every millimeter of thickness. For pieces with volume (river tables, deep molds) use the calculator, which applies each product's real density.
Density and specs by resin
Density tells you how many grams each milliliter of mix weighs, which is why ResinCalc uses each product's real value instead of an average. Most epoxy resins fall between 1.05 and 1.20 g/ml.
| Resin | Density | A:B ratio | Max depth per layer | Working time |
|---|---|---|---|---|
| Artline Crystal | 1.12 g/ml | 2:1 | 1.5 cm | 60 min |
| Artline Honey | 1.08 g/ml | 2:1 | 0.5 cm | 35 min |
| Artline Extra Honey | 1.10 g/ml | 2:1 | 1.5 cm | 30 min |
| Artline Wood PRO | 1.10 g/ml | 3:1 | 6 cm | 10 h |
Only deep pour resins like Wood PRO allow pours deeper than 2 cm per layer. The rest need the pour split into layers with a wait between them.
