Epoxy table Seal Coat

Table Seal Coat Using 2:1 Non-Blushing Epoxy

Thanks to Greg Carlson, owner of Century Farmstead, who built MAS Epoxies a custom conference room table.  He made it 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. We figured it was necessary since the Table Top Epoxy would protect our table from coffee stains and scratches.  But first, we had to seal the table off to prevent the Table Top epoxy finish from leaking. Below the process of applying a table seal coat prior to using Table Top Epoxy is outlined.

For best results this product should be used at 70-80˚F. First, you should apply a thin seal coat 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, should 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.  Before applying a table top epoxy, we recommend two thin seal coats with lightly sanding the epoxy in between coats.

Table Seal Coat Steps:

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

  • First, 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.

  •  Next, 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.

Now you’re ready to table top epoxy your surface or protect it with varnish!

Below is the step by step process we used on our conference table that was custom built out of reclaimed barn wood.  This process will work for your table seal coat as well.

STEP 1

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

STEP 2

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.

(2oo grams Resin – 100 grams Hardener)

STEP 3

After thoroughly mixing MAS Low Viscosity Resin and Slow Hardener, coat the entire table with epoxy.  Be sure to fill in all voids on the surface.  Because some voids may require more epoxy to fill them completely check for dry spots on your surface.  Also take into consideration the leaks some knots, cracks or seams may have.

STEP 4

Let the epoxy cure overnight after the table seal coat is applied. Inspect the surface the next day to check for voids and make sure the table is sealed completely. If the surface is sealed, prepare for Table Top Epoxy by lightly sanding surface, wiping with acetone and taping edges. While many people will apply a table top coating at this point you should apply a second seal coat if needed.

  1. The seal coat is brushed on in a thin layer and is used to seal any pores in the surface and prevent air bubbles from forming in the following flood coats.

    How much epoxy do you mix for your seal coat per square ft . Thanks

    1. MAS Epoxies

      Hi Bob! Great question. A 1/2 gallon of mixed material covers 40 square feet in a seal coat. Roughly 1.5 ounces will cover one square foot, but it depends on the porosity of the wood, knots and other factors as well. We hope that’s helpful!

  3. Hey Guys, I discussed this issue on the Instagram Messaging too. I have used several epoxy products over the past year, trying to find the sweet spot….Currently, I have three tables (16″x16″ end tables) that I poured with your product (Tabletop) and we are at the 10 day cure Point. I live and FL and the temp is perfect under your guidelines. Perfect Mix applied as well. Tables are beautiful and I love using your epoxy, but as a test run-I placed a coffee cup on one table about ten times, the cup left small scuff marks (not indentations) on the top. The marks do not rub off even with a small amount of scratch polish remover (something any person could grab to clean up their new tables). I am so frustrated, yes there is another product I have used that is super scratch resistant, but not user friendly. I have other projects that MASepoxy tabletop works great on, but nothing will ever come into contact with the surfaces. I watch everyone do their projects on Instagram, I have to wonder do they not care about scratches when they sell the items to customers? Thoughts?

    Thanks

      Hello Drew, thanks for reaching out. Although epoxy resin is considered scratch resistant and holds up to everyday wear and tear, it is not considered indestructible. Objects that harder than the epoxy will scuff, gouge or scratch the surface if proper care isn’t given. If the coffee cups have an uncoated ceramic back, you can actually scratch glass with that mug as well as virtually any room-temp cure epoxy surface. We always recommend placing a coaster down on any tabletop to mitigate any unnecessary scratches

        Thanks for the reply. I am throwing In the towel trying to find An epoxy that Will not scratch or scuff. I spent a lot of time asking questions and reviewing technical specs Let alone pouring different epoxies across the board, bottom line it will all scuff even the countertop epoxies. I love working with MASepoxies on all my projects, so moving forward My custom art tables will come with Care instructions, using coasters, and other items to protect the overall surface. Thanks.
