Each ton of paint streamed in your container will require water of about ½ cup to reduce the thickness. Now, mix the water and paint together and merge it properly with a paint stick or any other tool. Inspect the consistency and flow of the paint according to your requirement.

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.
