This stuff has my heart broken!!!! Moved into house last feb and undercoated downstairs no prob in water based paint but problem came when i moved upstairs. all the walls thats were block walls as opposed to stud partition would not take water paint. builder recommended oil based paint and it initially worked a treat till about 6 weeks later when all the corners started to peel off!!!! before i started to put the differents coulours on the walls i sanded down and removed all the paint that was coming off the walls. i now noticed nearly 4 months later that this paint is now begining to peel off!!! Any help or advice with this problem is greatly appreciated as it is really begining to get me down particularly with the wife constantly pointing it out to me:mad:
