3. Check paint flow and pour more water if required

Check if the paint flows fluently from the spray bottle or not. You may add the water if its consistency is not according to your requirement. Pour almost ⅛ bowl of water to reduce its thickness and then blend with the paint stick. If the flow suits you then it’s okay, otherwise again put on the same amount and blend it.
