What is the best primer (if any) to use when painting Apoxie® Sculpt with water-based paints?
The best surface prep is to wash the cured Apoxie® Sculpt surface with a light detergent or other cleansing agent. This will help the paint to adhere evenly, avoiding spidering, etc. Primers may be helpful, but are not necessary. Primers may be helpful to make the final show color more uniform, if desired. However, other users find that using a whiter base (e.g., Apoxie® Sculpt White color), when cleaned and top coated, is easier than using a primer, and shows the top coat color the best. If you choose to not use a primer, we recommend using a sealer to protect your paint work. (Note: Painting is optional, you do not need to paint over Apoxie® Sculpt or any of our products unless desired. * We also suggest that you follow the paint manufacturers directions, if it says to prime, then you should follow that suggestion to get the best results)
