Mixing Ratios for Layered Epoxy Resin Projects

← Back to epoxy resin, apply additional layers?

Working in layers with epoxy resin ensures strength and clarity in your finished project. Choosing the right mixing ratio for your resin type is vital for both appearance and durability, especially when building up multiple coats.

Key Mixing Ratios for Popular Epoxy Resins

Different epoxies use different ratios for resin and hardener, which must be followed precisely for proper curing:

EpoxyTable 5-Five: Mix 100 parts resin A with 55 parts hardener B by weight.
EpoxyFood: Also mixes at a 100:55 ratio by weight, ensuring a strong, food-contact safe cure.
Art Pro: Requires a simple 3:2 mixing ratio by weight (3 parts resin to 2 parts hardener), making it reliable for artists’ projects and surface coatings.

Always read the manufacturer’s guide for your resin, as correct proportions are essential to avoid tacky or brittle results.

Layering Techniques for Flawless Finishes

When creating thicker projects such as tables, river pours, or art, pouring in multiple layers prevents overheating and uncontrolled curing. For instance, EpoxyTable 5-Five is ideal for deep pours up to 5cm but even then, large areas or thicker builds may benefit from layering. Allow each layer to set before adding the next—timings vary but waiting 20–24 hours is common for deep pour resins, while thinner art resins might be recoated after 8–12 hours.

Follow mixing and curing instructions closely, and avoid changing component quantities to speed up curing or extend working time.

Practical Guidance for Buying and Use

Choose your resin based on project type and maximum layer thickness. For furniture and thick castings, “EpoxyTable 5-Five” is a top choice. For decorative trays or artwork requiring clear, glossy coats, “Art Pro” is both easy to mix and suitable for thin builds. If food safety is your priority, “EpoxyFood” is certified for contact with cold foods.

Measure accurately using digital scales and mix thoroughly but gently to prevent bubbles. Always use clean tools and containers for each batch, especially when creating layered effects.

When Mixing Ratios Matter Most

Getting the ratio right is especially crucial when layering, as any imbalance in previous coats can affect new layers’ cure and finish. Err on the side of accuracy—never guess component quantities and avoid eye-balling by volume unless the instructions allow.
