Painting wooden panels going up side of staircase which were previously satinwood finish have just realised that picked up wrong tin and have paInted over with Dulux silk vinyl emulsion.Had a750 ml tin of this and another tin same size of satinwood wood/metal paint.Rubbed original coating down well prior painting.Will the emulsion flake off and if not can I paint over with an oil based satinwood or just leave as is because it looks fine at the moment
