This is how the coasters are made:
Mix 5 to 6 tablespoons of concrete for 6 coasters according to the instructions. Pour the mixture into the moulds and tap them lightly on the work surface. This will cause the air bubbles to rise and the mixture to lie straight in the mould. The thickness of the coasters should be 1 cm. Let the castings dry for 24 hours.
After the drying time, you can unmould the castings. The excess edges should be sanded off so that the coasters lie smoothly. Then apply the weather protection impregnation with a brush on all sides. The sealant protects against dirt and moisture.
Now cut the cork paper so that the concrete does not cause any scratches. As a template, simply take the casting moulds and cut the cork paper with a minimally smaller diameter. To fix it securely, you should support the self-adhesive cork with a little craft glue.
Finally, you can decorate your finished coasters as you wish with a white marker. Whether sayings or motifs... we leave the design up to you.
Extra tip: If the concrete is too light for you, you can add a few drops of VBS colour concentrate in black to the mixture.
