Epoxy Resin

Epoxy is a two-part adhesive and coating system made of a resin and hardener that, when mixed, chemically react to form a rigid, durable material.

Epoxy is a specific type of resin known for its strength and adhesion, while the term "resin" covers a broader range of materials including polyester and polyurethane.

Most epoxies are tack-free within 24 hours but fully cure after 72 hours to 7 days depending on the product and temperature.

Epoxy bonds well to wood, concrete, metal, glass, and most rigid surfaces as long as they are clean, dry, and properly prepared.

Yes, cured epoxy is waterproof and resistant to moisture, which makes it a great choice for countertops, marine applications, and flooring.

Gently passing a heat gun or torch over the surface shortly after pouring will cause bubbles to rise and pop before the epoxy sets. For projects that require caps you can also use a vacuum chamber to suck the bubbles out and a pressure pot to compress the bubbles down while the resin is curing.

 A penetrating, low-viscosity epoxy works best for wood as it soaks into the grain, strengthens the surface, and creates a strong bond before any topcoat is applied.

Epoxy can be used outdoors but is prone to UV yellowing over time, so a UV-resistant topcoat is recommended for exterior use. Adding a pigment or colorant to the epoxy is another effective solution, as opaque colors block UV rays and prevent visible yellowing.

Standard coating epoxies should be applied no deeper than 1/8 to 1/4 inch per layer, while deep pour epoxy formulas are designed for single pours up to 2 inches thick, with most manufacturers recommending you step-pour in multiple layers if you need more depth.

UV light exposure causes a chemical reaction in the epoxy that breaks down its molecular structure, causing it to amber or yellow, particularly in products without UV stabilizers.
