Do you need to dilute paint?
Moreover, how do you dilute paint?
Add ½ cup of water for every gallon of paint. Mix thoroughly. Check the thickness by running the paint through a funnel. If it flows freely through the funnel, you know the paint is thinned enough.
Beside above, do I need to thin paint for sprayer?
It must be diluted or thinned with water to achieve a better consistency. Thinning your paint is most important if you intend to distribute a thin mist of paint, or if you are using a paint spray gun or nozzle. However, paint thinning is not merely mixing your material with water or thinner.
Before you thin the paint, acclimate the paint to ambient room temperature between 50 F and 90 F. Cold paint will flow more slowly and does not require thinning. If the paint is too cold, it may give a false impression that it needs thinning.
