Hi all, I had crazing over my first attempt to paint my bedroom walls and can only assume this was down to back prep of painting vinyl matt on top of silk paint. Now I have gone back to the old plaster. I am fairly sure it is now all dry. I am thinking of mist coating using the Vinyl Matt with a 70/30 - paint/water mix as mist coat. I have done some research and think this mix is better than the tin's 10 parts to 1 part water? I am almost 95% confident this is best solution. Rather than mixing contract matt as a mist coat, followed by vinyl matt. any wisdom would be great please? Its taken me hours to sort and got tennis elbow in process so really hoping my next steps are right ones?
