Grease-like stains coming through paintwork DIY hints, tips and solutions to the removal and repair of marked and stained areas

[maddy105]

moved into a house and have a strange grease-like stain on the wall that seems to come through the paint. Is there anything that could be painted over it before the paint to prevent it showing through?!
