Seal Coat on Table using 2:1 Non-Blushing Epoxy

Thanks to Greg Carlson, owner of Century Farmstead, who built MAS Epoxies a custom conference room table out of reclaimed barn wood that is over 100 years old! We decided it would be a great company project to apply our Table Top Epoxy system. But first, we had to seal the table off to prevent the Table Top epoxy finish from leaking. Below is the process of applying a seal coat to a surface prior to using Table Top Epoxy.

For best results this product should be used at 70-80˚F. A thin seal coat should first be applied to the table top or bar top and any object that will be embedded. Delicate objects that may be damaged by epoxy resin such as photographs, may need to be sealed with an alternate clear coat (i.e. polyurethane or acrylic sealers) to protect them prior to embedding. Once the seal coat has set, additional flood coats up to 1/8” thick may be applied. We recommend two thin seal coats with lightly sanding the epoxy in between coats.

MAS 2:1 Non-Blushing Epoxy is an easy to use system following these simple steps.

  • Pour Low Viscosity Resin into cup and mix Slow Hardener at a 2:1 mix ratio by volume.

  •  Thoroughly mix resin and hardener for 2-3 minutes.

  •  Pour epoxy into larger knot, cracks or seams to start.

  •  Using a foam brush or squeegee, spread epoxy across surface evenly.

  •  Once surface is covered. Let epoxy set, look for leaks or voids and plug with tape from the bottom.

  •  Wait for epoxy to cure. Lightly sand and apply the second coat.


Below, is a step by step process of our conference table that was custom built out of reclaimed barn wood.



Sand down surface and make sure it is completely level. Tape off any voids underneath the table to prevent seal coat of epoxy from dripping.



Mix MAS Low Viscosity Resin and Slow Hardener at  a 2:1 mix ratio by volume. Slow hardener will provide the longest working time of about 4 hours working in temps above 60 degrees F.

After thoroughly mixing MAS Low Viscosity Resin and Slow Hardener, coat the entire table with epoxy, filling in all voids on the surface.  Some voids may require more epoxy to fill them completely and take into consideration the leaks some knots, cracks or seams may have.

Once the seal coat is applied. Let the surface cure overnight. Inspect the surface the next day and check voids to make sure the table is sealed completely. If surface is sealed, prepare for Table Top Epoxy by lightly sanding surface, wiping with acetone and taping edges. Apply a second seal coat if needed.
