Picking the Right Resin

Which resin should I use for my project?
Do you offer sample kits?

Yes — sample sizes are available (handy for testing colour, clarity, adhesion and cure before scaling).

Mixing & Use

What is the mixing ratio for your epoxy resins?

Clearpox, StoneFusion and EpoxyPro use a 2:1 (resin:hardener) mix by volume. The Deep Pour system uses 3:1. Measure accurately and mix thoroughly, scraping sides and base of the cup.

How much resin do I need (coverage guide)?

Rule of thumb: 1 L covers ~1 m² at 1 mm (≈1000 cm³). Multiply area by thickness for volume, then add waste margin. Use the Resin Volume Calculator for exact pours.

What temperature should I pour at?

Ideal workspace is ~25 °C. Keep pours at ≥18 °C. Below ~15 °C cure slows and finish can suffer. You can gently warm bottles (~30 °C water bath) and condition the room.

How thick can I pour in one go?

Shallow seal coats: 0.5–2 mm; flood coats: ~2–4 mm. For deep castings, use the Deep Pour formulation or layer to manage exotherm/clarity. Test on a small mould first.

Can I add pigments, metallics or alcohol inks?

Yes — use epoxy-compatible pigments/pearls or alcohol inks. Add sparingly (often <5% by volume; for deep pours, stay far lower). Always test for the look and cure you want.

Clearpox 2:1 vs Deep Pour 3:1 — Quick Compare 2:1 = coatings / seal & flood coats • 3:1 = deep casting

Clearpox Ultra Clear 2:1

  • Mix ratio: 2 parts resin : 1 part hardener (volume)
  • Viscosity: medium
  • Best for: seal coats, flood coats, topcoats, thin casts, turning blanks, laminating
  • Self-levelling: yes
  • Working time: moderate (~25 °C, small mixes)
  • Typical layer: ~0.5–4 mm; up to ~10–15 mm with care
  • Turnaround: faster recoat/demould vs 3:1

Clearpox Ultra Clear Deep Pour 3:1

  • Mix ratio: 3 parts resin : 1 part hardener (volume)
  • Viscosity: very low
  • Best for: thick castings, deep cylinders, river sections
  • Self-levelling: yes
  • Working time: long (~25 °C, small mixes)
  • Typical layer: thick sections (follow label/mass limits; often up to ~50 mm)
  • Turnaround: slower overall cure vs 2:1

Tip: Seal live edges with a thin 2:1 coat, then pour the deep layer when tacky. For ~50 mm rivers, many still layer to manage heat/clarity. If you miss the tacky window, abrade 180–220 grit, clean, then pour.

Deep Pour & River Tables

Clearpox Ultra Clear vs Deep Pour — what’s the difference?

Clearpox Ultra Clear (standard): 2:1 mix, medium viscosity, quicker set in thin films — seal coats, flood coats, topcoats, small casts.

Deep Pour: 3:1 mix, very low viscosity, long pot life — thicker clear castings with reduced exotherm and excellent bubble release.

Is the Deep Pour 3:1 “self-levelling” like the 2:1?

Yes. Both self-level on a prepared, level surface. 2:1 is favoured for coatings/flood coats; 3:1 is optimised for deep casting where heat control and clarity are key.

What’s the typical working time?

It depends on mass and temperature. As a guide at ~25 °C: 2:1 ≈ ~1 hour in small mixes; 3:1 ≈ several hours. Always test in your conditions.

Can I use Deep Pour to seal live edges?

You can, but a thin 2:1 seal coat usually sets faster in thin films. If using 3:1, apply a very thin coat and pour the main layer when tacky.

How do I maximise bond between layers?

Pour the next layer in the product’s tacky/gel recoat window for chemical bond. If you miss it, lightly abrade (180–220 grit), clean, then pour.

Troubleshooting

How do I minimise bubbles?
  • Warm parts to ~25 °C; mix slowly; use a wide, flat stirrer.
  • Seal porous timber with a thin seal coat before flood coats.
  • De-gas with brief, careful heat-gun passes (don’t scorch).
Why is my surface hazy, sticky or soft?

Common causes: off-ratio mixing, poor scraping during mix, cold environment, moisture contamination. Re-coat only after full cure on a clean, keyed surface; remove uncured patches and re-cast if necessary.

Will the resin yellow in sunlight?

All epoxies slowly yellow with UV. For long-term clarity, use Clearpox indoors and consider a UV-stable topcoat for high-UV environments. Limit prolonged direct sun on clear finishes.

Is it food safe when cured?

Clearpox and StoneFusion cure to a non-toxic, VOC-free, inert plastic — suitable for incidental food contact (boards, benchtops). Allow full cure (often 7+ days). EpoxyPro trade/industrial systems are not assessed for food contact.

Pigments & Additives

How much pigment should I use by volume?

Short answer: start small and keep total non-reactive additives under about 5% of mixed epoxy (and far less for deep pours).

  • Transparent tint: ~0.1–0.5% of mixed epoxy
    Rule of thumb: ~1–5 drops per 100 mL.
  • Pearlescent powders (e.g., Jacquard Pearl Ex): ~0.5–3%
    Rule of thumb: ≈ ⅛–¾ tsp per 100 mL (½–3¾ tsp per 500 mL).
  • Solid/opaque with powders: ~2–5%
    Rule of thumb: ≈ ½–1½ tsp per 100 mL (2½–7½ tsp per 500 mL).
  • Deep pours: stay at the low end (≈ ≤1–2%) to control heat/clarity; heavy powders can settle — add swirls near gel if desired.
Use case % of mixed epoxy Guide / 100 mL Guide / 500 mL
Transparent tint 0.1–0.5% ≈ 1–5 drops ≈ 5–25 drops
Pearlescent powder (e.g., Jacquard Pearl Ex) 0.5–3% ⅛–¾ tsp ½–3¾ tsp
Solid/opaque with powder 2–5% ½–1½ tsp 2½–7½ tsp
Deep pours (limit load) ≤1–2% ⅛–½ tsp ½–2½ tsp

Guides only — always test first. Mix resin + hardener fully, then add colour. Pre-wet powders in a small amount of mixed epoxy to avoid clumps; scrape sides and base while mixing. Wear a P2/N95 mask when handling fine powders.

How much alcohol ink can I add to epoxy?

Alcohol inks are strong dye concentrates in solvent. Too much can soften the surface or slow cure. Keep totals small:

  • Veins/marbles & transparent effects: ~0.1–0.5% of mixed epoxy
    Rule of thumb: ~1–3 drops per 30 mL, or ~3–10 drops per 100 mL.
  • Absolute max: about ≤1% of mixed volume (including any isopropyl alcohol used for effects). If the piece stays tacky or rubbery, you’ve likely over-added.

Tips: Let solvent flash briefly before covering; use gentle heat sparingly to avoid pinholes; for items used around food, keep inks/pigments to decorative areas only and allow a full cure.

What pigments work best for countertops and river tables?

For stone effects, pair StoneFusion with metallic pearls and a touch of alcohol ink for veining/marble lines. For river tables, Clearpox with mica pearls gives depth without clouding.

Can I tint structural and composite systems (e.g., EP55/EP10/EP20)?

Yes — most systems can be tinted modestly without compromising cure. For composites (e.g., carbon fibre) use compatible tints and keep loading low to preserve mechanical properties and wet-out.

Safety & Compliance

What PPE and safety steps do you recommend?
  • Nitrile gloves, eye protection, covered skin; good ventilation.
  • Read the product’s SDS/TDS before use. Dispose of cured waste responsibly; never pour resin/solvents down drains.
  • Know basic first aid: wash skin with soap/water; flush eyes and seek medical advice if exposed.
Request SDS / TDS
Do you supply SDS/TDS for all products?

Yes — SDS/TDS and specs are available on request for trade and retail orders. Provide the product name and kit size so we can send the correct documents.

Orders & Shipping

How do you ship resin kits and bulk orders?

We use national couriers for parcels and road freight for larger consignments/pallets. Tracking updates activate once the carrier collects your order. For bulk drums or multiple 15–30 L kits, request a tailored freight quote.

Can I track my order?

Yes — tracking is emailed once your parcel is booked with the carrier. If you don’t see it, check spam or contact us with your order number.

Storage & Shelf Life

How should I store resin and hardener?
  • Keep sealed in a cool, dry place (ideally 15–25 °C), out of direct sunlight.
  • If resin thickens in cold weather, warm the sealed bottle in ~30 °C water before use.
  • Wipe threads after pouring; keep moisture out of containers.
What is the shelf life?

Unopened: typically 12–24 months when stored correctly. After opening: best within 6–12 months. Always check product label and batch details.

Quick Picks by Industry


General advice only: Always follow the product label and SDS/TDS. Test small before full projects, especially for deep casts or critical applications.

Project-specific advice policy: We’re happy to share general guidance from our pages, but we can’t engineer project-specific specifications or guarantee outcomes for unique builds. For deep pours and pigmented castings, please run a small test pour in your workshop conditions first. If your project needs detailed, project-specific advice, we recommend working with a local fabricator or epoxy specialist.
