No. The clear penetrating oil needs to penetrate in order to work, which means it needs raw/unsealed wood. If the chair is already painted (sealed) then you can not use a penetrating product over that. If you are looking for a top coat sealer for the high chair, we would recommend AFM Safecoat Acrylacq. If applied following instructions to the letter (and the paint you are going over is water based paint), once cured the surface is baby safe.
