Magnifico Resins created this practical deep pour epoxy mold size guide for preservation artists, mould casters, furniture studios and advanced resin makers. A 50 mm depth limit does not make every mould safe for one pour. Exotherm depends on depth, total mass, footprint, shape, ambient temperature, insulation, inclusions and material starting temperature. Record all variables, keep the batch plan conservative and stage the casting whenever the current TDS or technical review does not approve the exact geometry. Use it as a planning framework, then confirm the current label, technical data sheet and site conditions before work begins.
What Is Deep Pour Epoxy Mold Size and Exotherm Guide India 2026 and Why Does It Matter?

Quick answer
deep pour epoxy mold size is the process of matching material limits, substrate condition, batch planning and cure control to a defined result. A 50 mm depth limit does not make every mould safe for one pour. Exotherm depends on depth, total mass, footprint, shape, ambient temperature, insulation, inclusions and material starting temperature. Record all variables, keep the batch plan conservative and stage the casting whenever the current TDS or technical review does not approve the exact geometry.
In India, workshop temperature and site humidity can change quickly. Summer rooms can reach 35–40°C, shortening usable working time, while monsoon conditions can introduce moisture into wood, concrete and inclusions. Magnifico Resins therefore recommends measuring conditions, using ratios by weight, keeping batches controlled and postponing work when the substrate or environment falls outside the documented window.
Who should use this guide?
This article is designed for preservation artists, mould casters, furniture studios and advanced resin makers. Beginners can use it as a checklist, while professional teams can adapt it into a method statement, client approval sheet or site handover record. Magnifico Resins does not treat a glossy test as proof that every hidden layer is sound; the process must be verified from substrate to cure.
Technical Reference and Product-Fit Logic
Magnifico Resins product context: For general jewellery, coating and casting work, compare ONE Resin with 12H Resin. For the specialised process in this section, follow the named product's current label and written technical documentation.
Verified working reference
| Specification | Magnifico Resins reference |
|---|---|
| Reference 1 | 3:1 resin to hardener by weight |
| Reference 2 | 90-minute pot life |
| Reference 3 | maximum 50 mm single-pour depth |
| Reference 4 | 48-hour full cure |
| Reference 5 | high clarity and UV resistance |
The table summarizes the approved reference used for this draft. Every ratio is stated by weight. Never convert it to a volume instruction. For art-resin planning, ONE Resin uses 3:1 resin to hardener by weight, offers a 120-minute pot life, supports up to 20 mm and reaches full cure in 14–16 hours. 12H Resin uses 2:1 by weight, has a 40-minute pot life, supports up to 8 mm and reaches full cure in 12–14 hours.
How to make the product decision
- Calculate cavity dimensions and total resin mass before building the mould.
- Treat deep narrow blocks, insulated timber voids and large masses as different thermal cases.
- Dry and seal inclusions when appropriate before they enter the casting.
- Use staged pours when geometry, room temperature or total mass falls outside written approval.
- Prepare a safe response plan for unexpected heat, smoke, cracking or container distortion.
Magnifico Resins encourages a written go or no-go decision before materials are mixed. Record the product, batch, ratio, room condition, substrate reading, layer thickness and planned cure restriction. That small record is valuable when several people share a project or when a client asks why a specific method was selected.
Materials, Budget and Pre-Work Plan
Magnifico Resins product context: For general jewellery, coating and casting work, compare ONE Resin with 12H Resin. For the specialised process in this section, follow the named product's current label and written technical documentation.
Difficulty, time and team
Difficulty: intermediate to professional, depending on scale. Allow 30–90 minutes for scope and measurement, 2–8 hours for preparation, the product-specific working window for placement, and the complete cure period before service. Large floors, composite parts, wet areas and commissioned furniture should have a second trained person for mixing records, timing and inspection.
Indicative India cost planning
| Planning item | Indicative India budget |
|---|---|
| Rigid mould board and bracing | ₹1,500–₹8,000 |
| Sealant, release and leak-test supplies | ₹600–₹3,000 |
| Digital scales and temperature monitoring | ₹1,000–₹6,000 |
| Drying and sealing inclusions | ₹500–₹4,000 |
| Contingency tray and spill protection | ₹700–₹3,500 |
These are planning ranges in INR, not fixed Magnifico Resins prices or contractor quotations. City, access, substrate condition, area, tax, shipping and professional scope can change the total. Obtain the current specialised product price from Magnifico Resins and add at least 10% consumable allowance for trials, masking, mixing loss and quality-control samples. Do not reduce preparation to protect the material budget; weak preparation is one of the most expensive false savings.
Pre-start materials list
Prepare a calibrated digital scale, clean straight-sided mixing containers, separate measuring tools, timer, labels, lint-free wipes, appropriate personal protective equipment, dust control, surface-preparation tools, a level or profile gauge where relevant, and a protected cure area. Keep a printed job sheet with batch numbers and actual start times. Magnifico Resins recommends small test pieces whenever a substrate, colour system, mould, release material or cleaning method is new.

Numbered workflow
-
Step 1: Measure length, width, depth and irregular voids,
Measure length, width, depth and irregular voids, then estimate total mixed mass. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 2: Inspect mould strength, seams, release surface and
Inspect mould strength, seams, release surface and the ability to contain a leak. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 3: Dry timber and inclusions; keep wood moisture
Dry timber and inclusions; keep wood moisture below the 12% general guidance. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 4: Stabilize materials and room within the 18–32°C
Stabilize materials and room within the 18–32°C general cure range, using the product-specific target. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 5: Decide between one pour and staged layers
Decide between one pour and staged layers using current written limits for the exact geometry. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 6: Weigh resin and hardener at 3:1 by
Weigh resin and hardener at 3:1 by weight and keep each mixing batch within the safe 500 ml guidance unless approved otherwise. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 7: Mix slowly, transfer promptly and observe the
Mix slowly, transfer promptly and observe the mould without leaning over the casting. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 8: Monitor temperature and visible warning signs while
Monitor temperature and visible warning signs while keeping the area isolated and ventilated. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
-
Step 9: Allow the 48-hour full-cure reference before demoulding
Allow the 48-hour full-cure reference before demoulding stress, machining or final finishing. This checkpoint matters because the result of one stage becomes the substrate for the next. Record what was done, the environmental condition and any deviation before continuing. A disciplined pause here is usually faster than repairing a defect after cure.
Magnifico Resins field tip
Set a stop point before mixing: if the substrate is damp, contaminated, unstable, outside the approved temperature, or the crew cannot finish within pot life, pause the job. A controlled postponement protects both material and reputation.
Across Indian seasons, timing should follow the material and measured conditions, not a fixed wall-clock assumption. Magnifico Resins advises starting with a smaller batch during hot weather, keeping containers out of direct sun and protecting the cure zone from monsoon moisture, dust and unplanned traffic.
Common Mistakes, Diagnosis and When to Start Over
Magnifico Resins product context: For general jewellery, coating and casting work, compare ONE Resin with 12H Resin. For the specialised process in this section, follow the named product's current label and written technical documentation.
Five mistakes to prevent
- Treating 50 mm as the only variable
- Pouring into damp wood or fresh botanicals
- Leaving a deep casting unattended during the early reaction
- Mixing a large mass in one tall bucket
- Cooling an overheating reaction with unsafe improvised methods
Symptom-to-action reference
| Symptom | Likely cause | Next action |
|---|---|---|
| Local loss of bond or lifting | Moisture, contamination or weak substrate | Stop, expose a sound edge and investigate before repair |
| Soft or uneven cure | Incorrect weight ratio, incomplete mixing or cold conditions | Isolate the piece and seek product-specific technical guidance |
| Bubbles, pinholes or voids | Trapped air, porous substrate, moisture or poor consolidation | Correct the source; do not repeatedly overheat the surface |
| Crack returns through repair | Active movement or an untreated joint | Redesign the movement detail before recoating |
When to start over
Start over when the mix ratio is unknown, contamination is embedded through the bond line, the substrate remains wet or unstable, an active joint was rigidly bridged, or a structural composite does not meet its verified laminate requirement. Cosmetic sanding cannot rescue a chemically incorrect or poorly bonded foundation. Photograph the failure, retain batch information and contact Magnifico Resins with measured details rather than a vague description.
Safety warning
Do not touch uncured material with bare skin, add unapproved thinners, heat a runaway batch, or continue work in an unsafe space. Follow the current safety data sheet, use suitable protection and move people away from any smoking, deforming or rapidly overheating container.
Quality Control, Pricing and Client Handover in India
Magnifico Resins product context: For general jewellery, coating and casting work, compare ONE Resin with 12H Resin. For the specialised process in this section, follow the named product's current label and written technical documentation.
Build quality into the quotation
A professional quotation should separate investigation, preparation, application, cure protection and return visits. Magnifico Resins recommends showing clients why sample work, moisture checks, joint treatment or test coupons are charged activities. When these steps are hidden inside one low rate, they are often rushed first.
For a small handmade business, calculate selling price from material cost, consumables, labour, packaging, rejected-piece allowance, marketplace fees and target margin. For contractors, add equipment, travel, site supervision, protection, testing and shutdown coordination. Use INR throughout and avoid promising a margin before actual yield and rejection rates are known.
Handover checklist
Provide the product name, batch record, substrate and environmental readings, layer dates, cure restrictions, maintenance method, excluded damage and photographs. For work sold through Instagram, WhatsApp Business, exhibitions, local markets or Indian craft fairs, keep the same record with the order. A clear Magnifico Resins process record turns technical discipline into customer confidence.

Frequently Asked Questions
Magnifico Resins product context: For general jewellery, coating and casting work, compare ONE Resin with 12H Resin. For the specialised process in this section, follow the named product's current label and written technical documentation.
Can every mould be poured at 50 mm?
No. Fifty millimetres is a depth ceiling in the reference, not blanket approval for every mass, footprint, mould insulation or ambient condition.
Why does a large resin mass get hot?
Curing epoxy releases heat. Larger and more insulated masses retain that heat, which can accelerate the reaction and raise temperature further.
Should I split a deep cast into layers?
Stage the pour whenever the exact geometry is not approved, the room is warm, inclusions insulate the mass or technical guidance requires layers.
How dry should wood be?
Use wood below 12% moisture content under the general Magnifico Resins guidance and confirm with a suitable meter at several locations.
What ratio does Ultra Clear Casting Resin use?
Use 3:1 resin to hardener by weight, with careful scale measurement and slow mixing.
When can I demould the casting?
The reference lists a 48-hour full cure. Demould only when the product instruction and part geometry support it; thick sections can retain heat longer.

Choose the process before opening the pack
A 50 mm depth limit does not make every mould safe for one pour. Exotherm depends on depth, total mass, footprint, shape, ambient temperature, insulation, inclusions and material starting temperature. Record all variables, keep the batch plan conservative and stage the casting whenever the current TDS or technical review does not approve the exact geometry. The strongest workflow is measured, documented and conservative: verify the substrate, use the ratio by weight, respect thickness and pot life, and protect the full cure. Magnifico Resins supports Indian makers and professional teams with product-specific guidance for confident planning. Review the current product page for Ultra Clear Casting Resin, then select the general art-resin option that matches your project when the specialised system is not required.
