Making epoxy resin coasters isn’t hard.  You simply need a step-by-step plan and the best resin for coasters to help you get it done!

Here are the easy to follow steps to help you create a 90’s inspired resin coaster this weekend!

STEP 1:  Mix resin

Measure 2 ounces Resin and 2 ounces Hardener.  Mix the two parts together thoroughly, scraping the sides and bottom of the cup during mixing to make sure that all the resin is mixed.

STEP 2:  Add colors

Divide the epoxy resin for your coasters equally into 6 small cups. Squeeze a few drops of pigment into each cup and mix the color thoroughly into the resin.

STEP 3:  Pour resin into blocks

Pour each color in a block shape on the trivet.

STEP 4:  Remove bubbles

Air pockets tend to form in the corners of each cavity so if you have time before the resin begins to gel, use a toothpick to poke the resin into the corners. This will give you square corners on each pixel.

Always use caution when using a flame to avoid injury or mishaps.

STEP 5:  Demold

Once cured, pop the pixel blocks out of the mold by peeling the trivet away from the resin.

STEP 6:  Cut blocks

Cut the blocks into Tetris shapes. You will need to use a utility knife to get into the awkward corners where the scissors can’t maneuver.

STEP 7:  Mix more resin

Mix a 1 ounce batch of resin and color it with the black pigment. Pour it into the bottom of the coaster mold. Pop any bubbles by passing the flame across the surface, then set the mold aside until the surface has a firm “skin”. This will take several hours.

Work out how many pixels can fit along the bottom of your mold and then arrange the block shapes so that the pieces interlock for about 4 to 6 rows.

STEP 8:  Create patterns with the resin blocks

This is the most fun part of making these epoxy resin coasters.  Creating block patterns!

Place the blocks back into the trivet, face down, in the pattern you’ve just formed.  Place a piece of tape across the back to secure them all into position. Remove from the mold and trim the excess tape away.

STEP 9:  Add blocks to the black resin

Once, the black resin has gel-cured, align the long edge of the taped pixels at the bottom of the mold and carefully place it onto the resin, tape-side down, making sure that there is an even border all around it.

Position Pixels

Place another couple of Tetris blocks in the blank space above the main blocks as if they are moving down the screen. Set the mold aside for the black resin to cure.

STEP 10:  Mix clear resin

Mix more clear resin and pour it over the blocks.

STEP 11:  Remove bubbles

Use a toothpick or needle tool to work it down into the space between each block. Tease out any air pockets that have formed in between the pixels. Pop any bubbles. Let the resin fully cure.

STEP 12:  Demold

STEP 13:  [OPTIONAL] Finish with a layer of resin

If you want a domed finish to your coaster, mix an ounce of the Resin Obsession crystal doming resin and apply it to the surface.

      1. Thanks loads! I love Tetris, and have an old pc just for older games. I’ll have to make these for my brother, too. Christmas coming up!
