MDF coasters for sublimation printing but make a great canvas for Acrylic pouring or Bloom technique.
There is a protective plastic on the white side that needs to be removed before painting.
The underside has a cork backing already attached to protect your table. The back needs to be covered in masking tape to protect it from the paint until finished
After painting the top would need to be protected with a resin or a varnish the same as you would for ceramic tiles coasters.
