I recently had painters come in and paint the outside of the house. I noticed that they mixed the paint with water. When I questioned them about why they were diluting the paint, they said it was necessary in order for the paint to come out smoother. Is this true that you normally mix paint with water or are they just trying to save money? If so, should painting the inside of house also require diluting the paint with water.

No paint manufacturer that I know of tells you to dilute their product unless you are spraying it, where they? Diluting paint gets you no where since thinned paint will likely need several coats to cover.

Hi, jarbell1!

Were they diluting it all of the time or just some of the time, please?

Thanks!

When I questioned them about why they were diluting the paint, they said it was necessary in order for the paint to come out smoother. Many times on a day that is either to hot or usually cold, thinning paint is a normal practice. Yes thinning will make it come out smoother. The job talk is ( when you can't brush it out, thin it out)

If they are trying to save money then the jokes on them as bal1 mentioned here in coats. It's a hair split here. Don't know site conditions/temps


If so, should painting the inside of house also require diluting the paint with water

99% of the time that's not done unless you are spraying inside or out. Or again to cold.


Diluting paint gets you no where Some site temps require thinning of paint that's brushed on. It also depends on the quality of the paint which is basically how much pigment is put in it. I use Benjamin Moore which is a top quality paint and on occasions I need to thin it out

The only time any paint is thinned out/diluted is because it's a really HOT day painting an exterior door and the paint needs to be thinner to brush out better and not leave brush makes. Painting in the sun on a hot material is usually when that is done to a paint( it gets sticky). Then it's a gamble. Diluting paint too much not only weakens the paint it also cause the sheen to be duller.

Dilution is only done in very SMALL quantities at best.

Yes, they were spraying it on.

Ok paint must be a certain viscosity to spray and different equipment has different viscosity requirements. If the coverage turned out Ok they were reasonable to thin with water.
