Using a spray painter can make painting large areas a lot easier, and it means you will be finished in a lot less time, as well as requiring a lot less effort. Basically, a sprayer can be a lifesaver if you need to paint a large wall or surface.
However, using a sprayer requires you to know how to handle one, and one of the most important things to know is that you will almost always have to thin the paint. So to answer the question, yes, you have to thin paint for a sprayer, or else it won’t work properly!
But why do you have to thin the paint? Can’t you just put it in the sprayer and spray it?
It is because paint, especially latex paint, is usually quite thick, and a high amount of viscosity means it won’t be able to flow as easily. So although the emulsion of paint from the sprayer needs to be as thick as possible to allow for a good and durable coating, if it’s too thick then it won’t be able to flow through the nozzle!
Instead, the paint will get stuck behind the nozzle of the sprayer, blocking it and possibly causing some damage, which could outright ruin the equipment. Not to mention that if the sprayer isn’t spraying the paint then you aren’t getting any painting done.
So basically, you need to thin the paint so that it is able to flow through the sprayer in a smoother and easier manner, avoiding any blockage or complications.

Do I need to thin paint for an airless sprayer?
Airless sprayers use high pressure in order to shoot the paint out from the nozzle, making them super effective, as they can spray out a lot of paint very fast. But one of the main benefits of using an airless sprayer is that they work extremely well with thicker latex paints. In fact, if you had to choose a sprayer type for thicker paint, an airless sprayer would be the first option recommended to you!
This means that you don’t usually have to thin the paint in order to use it with an airless sprayer, making your life that much easier, and the process that much faster. However, it might depend, so if the paint is extremely thick you might still want to thin it out a little bit just to make sure there aren’t any problems or complications during the painting process.
But yeah, as a general rule, if you’re using an airless sprayer you can load up the latex paint directly, without the need to go through a thinning process.
Do you have to thin paint for an HVLP sprayer?
An HVLP sprayer, also known as a High Volume Low Pressure sprayer, is the best option for creating professional fine finishes on a coating of paint. These types of sprayers have the best transfer efficiency, which means that most of the paint is actually ending up on the wall that you’re painting, rather than being dispersed into the air and going elsewhere.
This helps them provide a smooth coating, excellent for details and advanced painting.
However, as HVLP sprayers have been designed for fine painting, they aren’t good at handling thicker paints. This means that you will almost always have to thin the paint beforehand, or else it might get stuck in the sprayer, blocking the nozzle and causing harm to the equipment.
Not to mention, that thinner paint is better for the finer painting anyways, so regardless of the sprayers’ capabilities (according to its brand and make), you should thin the paint out.
How much thinner do I need to paint a spray gun?
Thinner to thin the paint is often necessary in order to paint with a spray gun. This is because thick paint won’t be able to flow through the spray gun properly, and will instead get trapped and block the equipment, damaging it and disrupting the painting process.
But how much thinner do you need?
Well, there are different types of thinner, so the first thing is to make sure that it is suitable for the type of paint that you are using. As for the exact amount, it can also vary, so the safest bet is to carefully follow the instructions of the thinner product.
Nevertheless, here are some tips when using thinner with a spray gun:
- As a general rule, a ratio of 4 to 1, is a good amount of paint to the thinner.
- Thinner should be mixed in with paint that has been kept at room temperature. If the paint is too cold it might affect the thickness!
- Use a wooden spoon or stick to mix in the thinner when applying it to the paint. It is important that it is fully mixed before being used in the sprayer.
- You can add a few drops of water if the thinner is struggling to thin out the paint.
