Fill Voids

Start out by taping off the top of your slab. Yes, the top. I prefer to back fill the voids in order to save time flattening as well as save cost on the amount of epoxy needed to fill the void.

Mix up a 2 part Slow Setting epoxy. I use West Systems 2 part, I tinted mine for this application with Black Noir . Once tinted You want to pour into the top voids on the bottom of the slab. Slowly allow for the epoxy to seep into the void. Bubbles will rise. Use a MAP Gas or Propane Torch to pop the bubbles.

Sand the hardened finish with 80 grit. This will show any bubbles on the surface. Use a tinted FAST Setting epoxy to fill these holes.

Sanding & Surface Prep

Once the epoxy is flattened continue with your aggressive sander. I recommend a Festool Rotex 125 or 150 for this application. A belt sander works as well. Sand the whole surface with 80 grit, continuing to 120 on the aggressive setting. Then sand the sap wood (live edge) with a smaller headed sander to bring out the color and remove any bark or dirt.

Once the surface is prepped to 120 grit with the aggressive sander, Move onto a random orbit finishing sander. Mark the whole surface with a pencil and slowly remove the pencil with 120 grit.

Apply Finish

Once the surface is prepared to 120 grit, you can apply your Monocoat Finish. I have been using this awesome product, Rubio Monocoat. It has saved me tons of time and gives an amazing finish. Live Edge Slab - Rubio Monocoat Live Edge Slab - Rubio Monocoat

Finish the table in halves. Start on one side, then rub out the finish with a dry cloth. Continue this process over the whole top and apply to the edges with a rag.
