I painted 3 bedrooms , what a pain , the walls were so hot the wet edge was dry by the time I wetted the roller , then the paint went lumpy before I could find where to start again ,,, the perfectly good tin of oil based gloss had turned into minestrone soup over night , with lumps and grit in it , yesterday it was like glass ,,, then my fave harris brush decided to go '' hollywood'' all the hairs just kept falling out ,,,, so I went back to plastering ,, bonus is the render went on well and dried nicely too ,,, some days you win and some days your the landlord.
