Tips for Working with Epoxy Resin

Whether you're a seasoned professional or a DIY enthusiast, these tips will help you get the most out of your epoxy resin projects. Shop TAP Epoxy Resins by clicking here. From improving adhesion to achieving a flawless finish, here’s everything you need to know.

1. Use a Heat Source for Better Flow

Tip: Warm the unmixed epoxy resin and hardener in a heat source like the sun or warm water. Epoxies work best when the resin and hardener are 70 to 75 degrees Fahrenheit.

Why It Works:

  • In cold weather, this accelerates the curing process.
  • It significantly reduces viscosity, making the resin thinner and easier to mix.
  • Warmed resin penetrates wood more effectively, providing superior waterproofing for end grains and rot-prone areas.

Note: Warming resin shortens working time, so be prepared to apply it immediately after mixing. Unlike solvent-thinned 'penetrating' epoxies, TAP epoxies are 100% solids and virtually odor-free. However, always exercise caution when heating. Find Resin Hardeners with different working times by clicking here.


2. DIY Wood Putty with Sawdust

Tip: Mix sawdust into epoxy to create a custom putty.

Why It Works:

  • This putty forms a strong, gap-filling bond, perfect for attaching wood to irregular surfaces like brick or concrete.
  • The waterproof bond is robust enough for structural support, making it ideal for furring strips and similar applications.

3. Protect Wood Posts with Sand-Filled Epoxy

Tip: Mix sand into epoxy to thicken it to the consistency of peanut butter.

Why It Works:

  • Helps prevent wood posts set in concrete from rotting by forming a waterproof seal.
  • Forms a strong bond while reducing the amount of epoxy needed by up to 60%.

Application:

  1. Trowel the sand-epoxy mix around the base of the post to create a coved shape, directing water away.
  2. Once the epoxy begins to gel, sprinkle dry sand on top.
  3. After curing, brush off the loose sand to reveal a textured surface that blends with the surrounding concrete but remains weatherproof.
  4. In addition, sand and epoxy is excellent for filling small holes in concrete.

4. Goop Epoxy Paste for Crown Molding

Tip: Use Goop Epoxy Paste to install crown molding in hard-to-nail areas, like around brick fireplaces.

Why It Works:

  • The paste is sticky enough to hold molding in place while curing.

How to Apply:

  1. Spread a thin layer of Goop Epoxy Paste on the back of the molding.
  2. Press it into place and let it cure. No nails required!

5. Keep Resin Warm for Easy Handling

Tip: Store epoxy resin indoors during cold weather.

Why It Works:

  • Cold resin is harder to mix and won’t penetrate as effectively.

6. Cold Weather Application

Tip: When working in cold conditions, mix the epoxy and leave it in the container until it begins to warm up from the curing reaction.

Why It Works:

  • The warming indicates the curing process has started, ensuring the resin will penetrate effectively when applied.
  • Remember, once the resin heats up, your working time is limited, so act quickly.

With these tips, you can tackle a variety of projects more efficiently and achieve professional results every time. Happy crafting!
