I have noticed some of the paint on the outside of my window frames is starting to blister. I remember when the windows were installed they made a thing using about using microporous paint.
Does this mean I need to use microporous paint again?
If so, can I buy microporous primer, and is this needed?
Could or should I just rub it down a bit and use exterior paint?
Is water-based paint any good for outdoor use these days or should I be looking for oil-based paint?
Could I use the paint Network Rail used on the Forth Bridge :-)
