Trying to get a little advice regarding mistcoating. So much conflicting opinions on this on the web. I researched paints and dilutions to decorate a couple of rooms and decided on Leyland contract at a dilution of 15%. Now I’m concerned that the dilution might have been too thick. It says on the tin that the paint can be diluted by about this much but maybe that’s just referring to general use. I have finished one room with this paint/dilution combination (used Dulux Trade for top two coats) and it looks fine. Question is when will I know if I have ‘got away with it’? Will the paint begin to peel after a few days or could the paint start to flake a couple of months/years down the line? The walls were plastered a couple of months ago so completely dry. Any advice appreciated. Thanks.
