My kitchen ceiling has developed some cracks. I dare say I should get someone in to screw into joists or whatever but no time for that at present; want to make it look better in time for an unexpected visitor due soon. I want to fill the cracks and repaint and if that doesn't work will do the big job next time. Can anyone tell me what is the best filler on the market for this type of job at present. I haven't done any decorating myself for a while. Also, what is the best matt paint for a kitchen.
