Our large flowerpots make ugly, yellow marks on our floor because of the humidity. I had to solve this problem.
Cork is naturally water-resistant but not fully. When cork grains are heated they release a substance that works as a natural glue. When pressed together at the same time it is possible to shape the cork grains. You can buy cork sheets that do not have any other material or substance added to them, which makes them fully bio-degradable.
Beeswax is a natural material obviously and is fully water-resistant. Added together with flax oil it is used to varnish wood, such as a table for example.
I bought sheets of cork, beeswax, and flax oil and went into my workshop.
Cutting the Cork to Size
Mapping out the size of the bottom of the plant pot’s plate.
Sticking the paper cutout to the sheet of cork. I used a sheet that was 8 mm thick.
Used my jigsaw to cut it out.
Making sure it fits well.
Making the Beeswax Varnish
Melting the beeswax.
Measuring the flax oil and writing down every step.
Beeswax and oil mixture done.
Beeswax and oil mixture cooled down and set.
Spreading the mixture onto the cork plates like butter on bread. 🙂 The mixture filled in the small gaps in the cork which made the cork’s surface look way nicer. 🙂
Since the flax oil I used contained turpentine, which is a derivative from pine trees, its scent was strong. I let the cork coasters sit outside for a day in order to absorb into the cork and to aerate them.
The Final Result
I am so proud I completed this project. I started out with thin cork sheets, glue and sheets of plastic (see the previous post with the same title). When that did not feel right nor go well I looked for other solutions. This new version of my plant pot coasters you can compost if you no longer need them, which feels really good.
