I have wooden floorboards and have EVA foam mats where the kids play. I love the functionality of the mats being easy to clean and comfortable and provide a flat surface for the kids to play on eg train tracks, blocks etc. the problem however is that the kids have scribbled over the mats and they now look really awful and dirty. There is no way to get these marks off. Hence I am after some ideas of what other options are. My dh really hates rugs so that is a no. Could I try painting or spray painting over these mats? Are spray paints safe for kids? Any ideas appreciated!!
