Paint for a spray gun used to be expensive and difficult to find. Is it necessary to purchase specialized paint for a spray gun?
It didn’t matter if you were spraying interior or exterior environments. Past latex paints contained resins that were not compatible with water.
That meant only oil-based paint with petroleum solvents could be used.
Today’s latex paints are a different story. Modern latex paint contains a series of new synthetic resins that are compatible with water. So yes, you can think paint with water!
That makes it possible to create a thin consistency while maintaining the wetness of the paint for the sprayer. Now, paint for a spray gun is simple to find.
But, what sprayer paint will provide you with the consistent and professional results you require?
Because latex paint is a viable option today, oil-based paints are typically reserved for specialty projects now.
Modern latex paint can be applied in a variety of environments and is offered in several different color options. That makes it possible to use an airless gun with your paint, sometimes without the need to thin it.

When buying paint, you will notice that most cans, even the ones that say acrylic, will also be labelled as latex. This can be confusing.
The term latex seems to be applied to most paints (acrylic, vinyl acrylic etc.) because they are water based. If you are looking for 100% acrylic or an acrylic vinyl blend for your project, expect to pay more than with regular latex paint.
Latex paint does not contain latex from the rubber plant. The term ‘latex’ in the paint world refers to the binding agent in the paint. Folks that are allergic to latex, don’t have to worry about latex paint!
Latex is a water based paint and the terms acrylic and latex are sometimes used interchangeably. Water based means that the color or pigment of the paint is carried by water instead of oil.
Thankfully, latex paint have a short drying time and are easy to clean. Unlike other kinds of paint, latex paint has minimal odor and less chemicals called VOC’s* are in the air while you’re painting and as the paint dries.
*VOC stands for Volatile Organic Compound. These compounds become gases and vapors and come out of the paint when you are painting and as it dries. If you can, always purchase low VOC paint and if you can’t, wear a mask while working and ALWAYS work in a well ventilated area. you can even purchase environmentally friendly paint now. Fantastic!
If your latex paint is too thick, then it will clog the nozzle of your preferred gun. That creates a massive mess behind the trigger and can even ruin your equipment.
Thankfully, there is an easy process available to thin latex paint for spraying, so it meets the standards that the manufacturer expects. So, how do you thin paint for spraying? Can you thin paint with water? The answer is yes and…
It’s easier than you think!
Be sure to grab the following materials before getting started.
Thinning paint for a spray gun is a simple process that anyone can do. Once you’re ready to get to work, you’ll want to follow these steps.
#1. Pour all of your paint into the bucket that you intend to use for that day.
#2. Add ½ cup of water to the paint for every gallon of paint that was placed in the bucket.
#3. Mix the paint and water thoroughly with a clean stirring stick.
#4. Check the consistency of your paint by running it through the funnel.
If the paint is able to flow freely through the funnel, then you have the correct consistency.
Should the paint clog up in the funnel, then add another 1/8 cup of water to the paint/water mixture in the 5-gallon bucket for every gallon of paint used.
Then thoroughly mix the product with another clean stir stick.
Continue this process, adding 1/8 cup per gallon, as necessary until the paint flows freely through the funnel.
If your latex paint is still not thin enough for your spray gun, add small amounts of water and test until you reach the right consistency for spraying.
Note: Once water is added to latex paint, the characteristics of the paint will change. The color may be lighter or darker and the drying time may be different.
Thinner paint typically requires 3-4 coats for complete coverage and a desired finished, compared to 1-2 coats of standard latex paint.
Latex paints are the most common type of paint for spray guns today.
The combination of cost, shelf life, and longevity of quality make it one of the best paints available.
There are other types of indoor paint that will also work with a spray gun if they are thinned to the correct consistency.
Here are the most common options available right now.
How do you choose the best paint for a spray gun to get awesome results? Depends on your project and the end results you are looking for. There are times where an acrylic paint would be more suitable than a latex paint.
If you have a project that will experience big differences in temperature such as your house exterior, maybe even your kitchen or fence, an acrylic paint may be better for you.
Latex paints would be perfect for a high trafficked area with alot of wear and tear and that needs to be cleaned frequently.
|Chemical based||Water based|
|Good for Exterior||Longer Lasting|
|Used mostly for art projects||Costs less than acrylic|
|Requires paint thinner to remove||Dries faster than acrylic|
If you are eager to get your project finished, you might make the mistake of trying to complete the second coat before the first coat of paint has dried. So, how long should you let paint dry between coats?
It depends on a few factors: how you applied the paint, what type of paint, if you live in a dry or high humidity area, and whether it was exterior or indoor paint.
How long does interior paint take to dry? You should wait a minimum of 2 - 4 hours for paint to dry before a second coat of paint if you are brushing/rolling it on. Paint Spraying your paint means you can check it in an hour.
Regardless of how you applied the paint, avoid rubbing or putting pressure on the newly painted area.
Those of you that live in high humidity areas will need to wait longer, up to 24 hours to be safe. Use your judgement based on the interior paint type that you used for your project.
Typically, when applying spray paint, the layer of paint is thinner than when you brush or roll it on. If you are using thin latex paint for spraying, your dry times will be less than if you brushed/rolled it on.
This means you can paint more surfaces faster with your sprayer than the alternatives. We recommend waiting an hour and testing your newly painted surface in a hidden area. If it's dry, you are ready for your second coat!
Most of us use latex paint regularly. Latex paint dries relatively quickly compared to chalk paint and oil based paints. This is because latex paint is water based and some brands are even labelled "fast drying".
So, how long does it take for latex paint to dry? Follow our basic guideline of 2-4 hours and test the newly painted surface in a hidden area.
So, how long does paint last in a can ? Well, that depends on several things. If the can has been opened, what type of environment are you keeping your can (heated garage, cold basement), if you live in a high humidity area versus a low humidity environment, and what type of paint it is.
Depending on the level of humidity, your paint can dry up much faster in a can that has been opened. Not only that, low humidity levels can change the color and finish of the paint!
We recommend testing it in a hidden area or on a piece of cardboard and allowing it to dry before beginning to paint an entire wall. Learned this the hard way and had to repaint an entire bathroom!
According to Consumer Reports, depending on the type of paint, can last for years or go bad in months. Water based paints are especially finicky.
The best thing to do is to a) label the paint with the date of when you opened and used it and b) check the consistency of the paint for a rubberlike surface or if it's become thick and doesn't stay properly blended for 10-15 minutes after mixing.
You can use any paint anywhere, but it is recommended that you use indoor paint only on your indoor surfaces.
Why? Not only will your results not be what you expected if you use exterior paint indoors, but indoor paints are specifically formulated for indoor wear and tear.
They allow you to scrub and clean them and they resist staining. Indoor paints are low VOC, meaning they emit much less chemicals into the air while you are painting, while the paint is drying, and afterwards.
Exterior paints are designed to battle the outdoor elements and resist fading and mildew. They are great at resisting humidity and UV exposure.
The only instance we can recommend an exterior paint indoors, is for a very high humidity bathroom. Even then you can find indoor paint that will resist humidity and mildew.
Painting latex over oil paint requires special preparation to make sure that the water based latex paint bonds with the oil paint.
Without proper prep technique, you could end up with cracking and flaking paint! To do the job right the first time, we do suggest using oil based paint instead of water based.
If you insist on using latex over oil paint, the following steps should be taken to create a good base for the latex paint to stick to. According to www.bobvila.com
|Oil based||Water based|
|Richer Color||Good for Walls/Ceilings|
|More Durable||Budget Friendly|
|Stands up to low/high heat||Dries fast|
|Covers stains: no bleed through||Easy Clean up|
|Dries slowly||Not as durable|
|Longer Clean up||Stains may bleed through|
Most latex paints that are suitable for a spray gun range in price from about $20 per gallon to over $60 per gallon. Certain specialty paints may run even higher than this.
Be careful about shopping for interior latex paint if you intend to use a spray gun. Several paint manufacturers have started combining primer and latex together for faster user application.
These are difficult to use because the thinning process changes the characteristics of the paint.
