How to use acrylic paint and marker on rubber things?
The surface needs to be properly degreased before use: wash in spring water or wipe with rubbing alcohol and dry properly Rubber does not need any special treatment. Since rubber does not have a porous surface, as with glass, for example, two coats may be needed for maximum hiding power. We recommend waiting until the first layer has completely dried before applying the second layer. However, for most surfaces only one coat will suffice.
Fixation
Fix the product with a water-based acrylic colourless varnish. The surface is waterproof after drying, but not abrasion resistant.
