Epoxy and Wood Star Holiday Decoration
January 8, 2018
Epoxy can help make wooden decorations last a long time. For this project, I will be painting and decorating a large plain wooden star that I found at a local craft store and then sealing it with epoxy. This application process can be used with any size and shape wood decoration. Make sure to use a water based stain/paint. Oil based paint/stain is quite difficult for the epoxy to bond to it. It takes a lot of thin coats and sanding to get the epoxy to look nice over oil based stain/paint. It can be done but it just takes a lot of work and that is a project for another blog post.
- Wood star (or other shape)
- AeroMarine Products 300/21 Epoxy Resin and Hardener
- Water based metallic wood stain/paint
- Blue painter’s tape
- Plastic measuring/mixing containers and utensils
- Inexpensive brushes (I used 1 inch chip brushes)
- Acetone and clean oil free rag
Your work area:
- Clean, level work surface, covered in paper or plastic for easier clean-up.
- All materials comfortably within reach.
- This star had a loop of twine at the top of it, so I taped that down and out of the way first. Then, I applied a water based metallic stain/paint according to the product directions. I used a 1 inch chip brush and applied 2 stain coats, waiting 12 hours between coats. After the last coat, I waited 72 hours before applying the first coat of epoxy.
- Before I applied my first coat of epoxy on the whole star, I did a little test area on the side of the piece. I did this because it was my first time using this particular stain/paint. I didn’t think there would be any issue because it is a water based material intended to go over wood, but better safe than sorry. The test spot turned out fine, so I proceeded with the full application.
- The 300/21 Epoxy is mixed 2:1 by volume. I measured, mixed in a clean container, then after mixing for a couple of minutes, poured it into a new, clean container and mixed for a few more minutes. I did this to make sure the epoxy was completely mixed and there wouldn’t be an unmixed material clinging to the sides of the mixing container. Any unmixed resin or hardener will make it difficult for the the epoxy to properly cure. I mixed up a total of 3 ounces, which is a very small batch.
- Next, I used a 1 inch chip brush to apply a nice thin coat all over the star, brushing the sides as well.
- I let each coat of epoxy cure for at least 24 hours before applying the next coat. If I had mixed a larger amount of epoxy (at least 6 ounces), if the weather was warmer or if I had a heater running in my work space, I would have only waited 12 hours between coats. Smaller batches and colder temperatures cause the epoxy to cure more slowly which is why I gave it each coat more time to cure. This epoxy does not need to be sanded between coats, unless it has been longer than 2 weeks since the previous application.
- Once I had 3 brush coats of epoxy applied and cured, I taped off the edges of the star with painter’s tape. I want to apply glitter just to the center of the star and have a nice border of just plain gold.
- Once the edges were taped up, I mixed up and applied another coat of epoxy just to the middle of the star. Then, I sprinkled glitter on to the wet epoxy. I let it cure for 24 hours and the applied another coat of epoxy.
- After the epoxy cured, I removed the tape. I used some acetone on a clean, oil free rag to wipe the entire surface of the star, focusing on the areas that had been taped. You really want to make sure the cloth/rag you are using does not have any oil residue on it. Oil contamination will make the final coat of epoxy look uneven.
- After the acetone has evaporated (just a few minutes), I mixed and applied the final coat of epoxy. The last coat will even out the difference between the glitter area and the border.
You can see the sharply delineated edge between the glitter and border and how the final coat really smoothed the whole piece out. This whole project took about week, applying a coat of epoxy a day. You can check out our epoxy page here, https://www.aeromarineproducts.com/product-category/epoxy/
