How much water can you safely add to acrylic paint without affecting its integrity?

It is possible to add water to the acrylic to make it more fluid, but it is advisable to respect the ratio of the paint manufacturer, in principle around 50% water, otherwise there is a risk that the binder of the acrylic paint is no longer effective.

Depending on your project, if you need to make your acrylic paint in tubes very fluid, it is possible to avoid using water by taking mediums designed for this purpose, or even to use a thinning additive flow-aid from Liquitex for example.

It should be noted that by adding a medium or water, you will affect the opacity of your paint by making it more transparent. If this is not your goal, it is better to use a fluid acrylic paint such as Golden fluids for example.
