For optimal results, ensure the water temperature is approximately 60 degrees Celsius. You might also be contemplating how to thin water-based paint for your spray guns, which can be another aspect to explore in achieving the desired viscosity.

Each paint formulation is unique, composed of distinct compounds and chemicals, often varying in viscosity. Unfortunately, this diversity can occasionally result in issues and blockages within the paint gun while working on a project. 

These complications can lead to time delays and have you toiling away into the late hours of the night. Additionally, the amount of water added may differ every time you thin paint for your spray gun. 

However, the precise quantity of water you incorporate matters more than the frequency of mixing. 

It is more valuable to discover what works best for your specific needs and preferences rather than relying on generic numbers provided by others based solely on their own experiences.
