Hello everyone,
I am currently planning to apply paint to an IKEA KALLAX insert and wonder how well paint generally adheres to melamine-coated surfaces. Does anyone have experience with this or can advise if there are specific pretreatments or types of paint that are particularly suitable?
I understand that melamine has a very smooth, hard surface that might affect adhesion. How do you handle issues like adhesion, drying time, and potential chipping with such coatings?
I would appreciate any tips, especially if someone has previously painted a KALLAX insert themselves and can share which methods work well long-term!

They are often made of laminated chipboard with plastic edge bands, which can make adhesion more difficult.This is an important point that many people underestimate. Edge bandings behave very differently compared to melamine surfaces. So if you only focus on melamine, you miss this crucial issue.
My advice: to be on the safe side, you should replace the edges with special finishing edge tape or sand them down until bare wood is visible and then reseal. Otherwise, you may get unpleasant chipping later on.
Regarding adhesion: There are silane-based adhesion promoters that have proven effective for melamine coatings. These significantly improve the chemical bonding.
Sanding with 180 grit is usually sufficient. Coarser grit is unnecessary, as it can create excessive roughness.
I recommend the following procedure: cleaning (isopropanol or a similar solvent) – light sanding – adhesion promoter – primer – paint application.
Also consider the different coefficients of thermal expansion of the materials. Therefore, avoid applying paint too thickly and be mindful of sensitivities.
