No, you don\'t
need to, it just helps - I don\'t get tide marks and I thin with water only about 99.9% of the time.
If you read further in my post,I comment on the item that there are indeed painters that use no additives.
Regarding the stabbing of brush strokes, I would also recommend not stabbing as you can create an unwanted texture effect by doing that as the paint builds up repetitively. Good for certain things but preferably you\'d want to practice smooth strokes, in one direction, and once the paint is down on the piece, leave it to settle and dry as you can introduce brush stroke/unwanted texture by messing with it while drying.
Unless you\'re feathering or wet blending but those are techniques which stand on their own right and have different approaches.
I looked at your pics and I\'m thinking that you should try a couple things mentioned here, adding some kind of surface tension breaker to pure water would be a good start, see if it helps. Flow aid from the various manufacturers is a good item to have. Wouldn\'t recommend using Floor wax such as Future although it\'s used often by people for the same purpose, it has side effects you\'d be better off without, proper acrylic Flow aid is much better.
