Picking the Right Resin
Which resin should I use for my project?
- Boats & marine laminating/repairs: EpoxyPro EP10 (coating/laminating EP1010; structural EP1020).
- Timber coating, laminating & repair: EpoxyPro EP40 (EP4010 low-visc for coatings; EP4020 high-build filler).
- Countertops / benchtops (stone-look veining): StoneFusion Countertop Epoxy.
- General purpose bonding/casting: EpoxyPro EP60.
- Electronics potting/encapsulation: EpoxyPro EP20 series (Electrical & Electronics).
- Pool & spa maintenance: EpoxyPro EP70 series.
- Pebble/stone flooring binder: EpoxyPro EP80.
- Concrete floor priming/sealing: EpoxyPro EP8510.
- Penetrating waterproofing/primer: EpoxyPro EP30.
- Ultra-clear art, casting, river tables: Clearpox Ultra Clear.
If you’re unsure, start with a small kit or a sample kit to validate flow, clarity & cure in your conditions.
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 a mix ratio of 3:1. Always measure accurately and mix thoroughly, scraping the sides and base of the cup.
How much resin do I need (coverage guide)?
As a rule of thumb, 1 L covers ~1 m² at 1 mm thickness (≈1000 cm³). Multiply your area by desired thickness to estimate volume, then add a margin for waste and edge losses.
What temperature should I pour at?
Ideal workspace temperature is ~25 °C. We recommend keeping pours at ≥18 °C. Below ~15 °C cure slows markedly and finish quality can suffer. You can gently warm resin/hardener bottles (~30 °C water bath) and condition the room to maintain target temps.
How thick can I pour in one go?
It depends on the system and geometry. Shallow seal coats are typically 0.5–2 mm; flood coats ~2–4 mm. For deep castings or cylinders, use our deep-pour formulation, otherwise plan multiple layers to manage heat (exotherm) and clarity. If in doubt, 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; some effects far less). Always test for the look and cure you want.
Deep Pour & River Tables
Clearpox Ultra Clear vs Deep Pour — what’s the difference?
Clearpox Ultra Clear (standard): 2:1 mix by volume, faster set in thin films, commonly used for seal coats, flood coats and topcoats.
Clearpox Ultra Clear Deep Pour: 3:1 mix by volume, very low viscosity and long pot life for thicker clear castings with reduced exotherm.
Is the Deep Pour 3:1 “self-levelling” like the 2:1?
Yes — both systems level on a prepared, level surface. The 2:1 is often used specifically as a self-levelling coating/flood coat; the 3:1 is optimised for deep casting where heat control and clarity are key.
What’s the typical working time?
Working time depends on mass and temperature, but as a small-batch guide at ~25 °C: a standard 2:1 mix is around an hour; a deep-pour 3:1 mix can be several hours. Always test in your conditions.
Can I use Deep Pour to seal live edges?
You can, but we usually recommend a thin seal coat with the 2:1 system because it sets faster in thin films. If you use Deep Pour, apply a very thin coat and wait until it’s tacky before the main pour.
How do I maximise bond between layers?
Pour the next layer in the product’s tacky/gel recoat window for a chemical bond. If you miss that window, lightly abrade (180–220 grit), clean thoroughly, 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 passes of a heat gun/torch (don’t scorch).
Why is my surface hazy, sticky or soft?
Common causes: off-ratio mixing, poor scraping during mix, cold environment, or moisture contamination. Re-coat only after a full cure and a clean, well-keyed surface; spot-remove uncured patches and re-cast if necessary.
Will the resin yellow in sunlight?
All epoxies slowly yellow with UV exposure. For best long-term clarity, use Clearpox for indoor pieces and consider a UV-stable topcoat for high-UV environments. Keep prolonged direct sun to a minimum on clear finishes.
Is it food safe when cured?
Clearpox and StoneFusion form a non-toxic, VOC-free, inert plastic once fully cured — suitable for incidental food contact (serving boards, benchtops). Allow full cure (often 7+ days, depending on conditions). EpoxyPro trade/industrial systems are not assessed for food contact.
Pigments & Additives
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; don’t pour resin/solvents down drains.
- Know basic first aid: wash skin with soap/water; flush eyes and seek medical advice if exposed.
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. If you need a tailored freight quote for bulk drums or multiple 15–30 L kits, contact us.
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.

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.
