DIY Resin Beach Coasters

Bring a bit of the beach into your home with these DIY beach-inspired coasters made of resin and real sand!

Hey Resin Crafters! Lindsay from Artsy-Fartsy Mama here with a beach-inspired resin project. The beach is one of my favorite places to visit. I love the feel of the sand on my toes, the beautiful blue color of the ocean, and the calming sound of the waves. We recently took a trip to Turks and Caicos and brought home some sand that I decided to use to make coasters as a beautiful reminder of our trip!

Supplies you will need to make your own DIY Resin Beach Coasters:

• Envirotex Lite
• Gloves, Mixing Cups, Stir Sticks
• Castin’ Craft Transparent Resin Dyes – Blue, Green
• Castin’ Craft Opaque Pigment – White
• Beach Sand
• 4″ Circle Coaster Mold
• Hair Dryer, Straw, or Heat Gun

Step 1:

To make one coaster, you will need about 3 oz of resin. Wear gloves to protect your hands, and pour equal amounts of resin and hardener into a mixing cup. Use a stirring stick and mix the resin well for 2 minutes. Pour the resin into a clean mixing cup and stir for another minute.

Step 2:

Add some sand to a small mixing cup. I used about 0.5 oz for one coaster. Add a little bit of resin to the sand and mix it well until all of the sand is coated. The consistency should be like a paste. If it’s too runny, add a little more sand. If it’s too thick, add a little more resin.

Step 3:

Pour the sandy resin into one third of the mold. It’s important that it has a paste consistency, otherwise it will spread and level itself throughout the mold. There will be a lot of bubbles that rise to the top, but we will take care of that later.

Step 4:

Pour about 1 oz of resin into a mixing cup. Add 3-4 drops of blue and 2 drops of green transparent resin dye into the resin to make a light, teal color. Use a clean stir stick and mix well.

Step 5:

Pour about 1 oz of resin into a mixing cup. Add 3-4 drops of blue transparent resin dye into the resin to make a deep blue color. Use a clean stir stick and mix well.

Step 6:

Pour some of the teal resin in the center of the mold and over about half of the sand resin. This will be the shallow end and shore of the ocean. Don’t worry about any bubbles that rise to the surface.

Step 7:

Pour some of the blue resin into the left third of the mold. This will be like the deeper part of the ocean.

Alternate pouring the teal and blue resins into the mold until both cups are empty. This will help the two colors blend better so you don’t have a harsh line of color in the mold.

Step 8:

Pour about another 0.5 oz of resin to another mixing cup. Add a small drop of white opaque pigment to the resin and mix well with a clean stir stick.

Step 9:

Carefully drizzle some of the white resin over the area where the teal resin is covering the sand. Try to make thin, vertical lines instead of drops and pools of resin.

Step 10:

Now it’s time to turn those lines of white resin into sea foam! Use a straw, hair dryer or a heat gun on a low setting to blow the white resin in all directions. This will gently blend it in to the lighter teal resin and give the effect of sea foam. This step will also pop all of the surface bubbles in your resin! Be careful not to use too much heat and to work quickly for best results.

Let the coasters cure overnight in an undisturbed area. Carefully remove the coasters from the mold, and sand down any edges if necessary.

Just like the beach, no two coasters will be alike. Since these coasters are made of our sand souvenir, we are sure to keep our beach vacation memories alive while sipping on our favorite drinks! You can also get sand at the craft store and make gorgeous coasters as a gift, or to keep as a unique conversation piece on your coffee table at home.
