Can you thin paint with water
I am looking to re-paint my hallway, years ago I used a Ralph lauren paint but it seemed very thick and almost left a textured look on the wall (a bit bumpy and grovy pitted) but for the basement I used a cheap canadian tire paint and it went on soooo smooth loved it.
I was wondering can I add water to the paint to thin it out a bit would this give me more of a smooth finish rather then pitted?
Second what size of roller do you recommend? I think I used a 15mm
