Have you ever wondered why your spray gun’s nose gets clogged with paint? And it always seems to happen at the most inconvenient time, like after you just climbed a 2-story ladder or when you’re in a hurry so much so that you may wish to avoid the paint getting dried when you have last painted. So clogged paint for a spray gun is a clear indication that the paint is thick and would not allow us to spray smoothly. It is an obvious problem for painters.

A successful spray painting project requires the right painting technique and thinning the paint before spraying. We have tried various painting jobs after thinning paint for the sprayer, the experience seems smoother, and the result is far more pleasing. Therefore, we must know how to thin paint for a sprayer!

Thinning Paint For Sprayer

 If you want to use different kinds of paint, you need to thin them differently. Spray guns use three types of paint globally.

 1- Acrylic-based paint 

 2- Latex-based paint 

 3- Oil-based paint 

We are sharing the pro tips we have learned from using these spray paints that can be helpful with your projects.

Once you learn the correct way to thin paint, you will not have to change paints or spray guns as frequently due to clogged nozzles. In this guide from Holapaints.com, painters like you will discover how to thin paint for sprayers, and you will also learn how to: 

  • Check the paint’s consistency before spraying.
  • Prepare the tools for thinned paint. 

Ideally, we need to know the paint to the thinner ratio for a spray gun to simplify the whole process. We find that water and paints have distinct properties.

Paints are made from several compounds and chemicals, all of which act in different ways and have different viscosities, which can clog a paint gun and affect the drying time. As a result, you will be adding different amounts of water each time you thin paint for spraying. Since that is true, learning how to do it is much more valuable than being told how much water to use.

How To Thin Paint For A Sprayer: Be Prepared With The Right Equipment!

1- Paint- Generally, paint is classified into two groups: water-based paints or latex paint and oil-based paint or alkyd paint. Water is the medium used by latex paint, while petroleum-based solvents are used by oil-based paint. (Source: Paint history from Joepullaroinc)

You need to have enough paint available at your end to color the surface. As there is no way to color the surface you are covering without paint. 

2- Thinners such as water are commonly used to thin paint for latex paints.

Generally, paint thinners were made of the following solvents:

  • Turpentine
  • Acetone
  • Naphtha
  • Toluene
  • Methyl ethyl ketone
  • Mineral spirits or White spirit
  • Lacquer thinner
  • Any of the glycol ethers, including 2-Butoxyethanol

3- A funnel will be necessary for you to determine the paint’s viscosity. To ensure when the paint is at the right consistency.

4- Spray gun– You can use thinning paint for professional airless sprayers, HVLP sprayers, handheld Wagner or Graco sprayers for painting purposes.

5- Test surface- It is best to use a small piece of cardboard or another test surface so you can spray the thinned paint on it and make sure it adheres to the surface.

* Is It Best To Thin Latex Paint Before Spraying It?

It is necessary to thin latex paint before using handheld sprayers, airless paint sprayers, or HVLP sprayers due to their thick consistency. You can thin paint with water, which is a fairly simple process, and add the paint to a cup and stir gently. Check out the entire process below.

How to thin latex paint for sprayer?

Start by opening the paint container and thoroughly blending the paint. If a machine has already mixed the paint in a store, Then you may skip this step.

Step 1: ( Thinning Latex Paint For Sprayer )

At first, you must be highly cautious. You need 12-13 ounces of water per gallon of paint, and it is a 10% volume requirement for every gallon of paint. If you want the perfect consistency for your sprayer tips, you should use a paint strainer. Please be advised to use a stir stick to mix the latex paint for a spray gun. 

Step 2:

A funnel is an open-ended test to determine whether the paint’s consistency is suitable for spraying latex paint. You should see the mixture flow freely from the end of the funnel if you pour it slowly. 

Do not waste any paint or water by doing this open-ended funnel test over a bucket or a mixture of paint and water.  

You should take the next step if the first pass did not result in the free-flowing fluid. If a clog is found, you can try using a strainer.

Step 3:

Latex paint thinning

The volume of the paint that we have used previously was 10 percent. You may need to mix paint 10% at a time and gradually increase the amount required.  

There is a crucial spot where the paint is not too diluted, yet it flows well through the funnel, especially since the spot is different for each type of paint. Do not jump up to increase the ratio drastically because you may miss it. 

Step 4:

Once the paint is properly thinned, you can test it out and spray it on the sample surface after loading it into the sprayer.  

As a result, your spray will spread uniformly, and you will not have problems getting stuck or slowed down. If the paint is clogged in the nozzle of the sprayer or it feels like it is slowed down, you might need to mix the paint again.

Step 5: (HVLP for Latex Paint)

You can now spray paint any surface you wish using the smooth experience. Plus, your paint is likely to last longer since you thinned it during the mixing process, which saves you money and increases the life of your paint.

Mainly, a minimum of 10% of latex paint per quarter cup of water should be used when thinning latex paint. Increasing the water percentage by 20-30% when using an HVLP sprayer or handheld system might be necessary.

* Thinning Paint For Spraying Acrylic Paints

Thinning acrylic paint for spraying is easy due to its water-based formulation. Thinning paint for sprayers requires a certain amount of care, as you should not overdo it. Adding too much water to the paint can cause it to flake off because too much water will affect their ability to bond.

Acrylic latex paint

Acrylic paint can be mixed up to 50% with water when applied to an absorbent surface. However, it is advised to avoid mixing more than 30% of the water on any other surface.

* Thinning oil-Based Paint For Spray Guns: 

It is necessary to thin oil-based paints, like semi-gloss enamels, before applying them to the surface. Oil-based paints tend to be slightly thinner than latex paints but still need to be thinned for best results. You can determine the ratio of paint to thinner in a spray gun by reading the manual guide.

In the guide, you will need to find which thinner is best for the oil-based paint since water is not the best choice. Most oil-based paints need 10% thinner. It depends on three variables:

  • An applications type.
  • Paints quality.
  • Spray Gun.

* What Is The Best Way To Thin Emulsion Paint For Spray Guns?

Water-based paints are emulsions. You can thin it with water; however, this requires more coats to achieve a good finish. Most manufacturers recommend thinning down emulsion paint for spraying with a 70/30 ratio, and it needs to be 70% paint and 30% water.

Sometimes, painters also prefer an 80/20 ratio, but what works best depends significantly on the paint you’re using and how thick it was in the first place.

FAQs (How To Thin Paint For Sprayer?)

How much paint to the thinner ratio for sprayer do we need?

Manufacturers often specify a ratio of paint to thinner on paint container labels. Painters should maintain a greater quantity of paint than paint thinner. A 4:1 or 3:1 ratio of paint to thinner or a similar ratio works well for general purpose thinning paint. You should keep the paint quantity higher than that of paint thinner to achieve the best results.

What is the best way to thin paint?

Professionals usually take one part mineral spirits, or turpentine to three parts paint to make the paint flow better and for even consistency. Mix well with a stick. Try out the spray pattern on a test area and examine the results. You can add thinner if the paint remains thick.

Can water be used to thin out paint?

If stirring does not thin your water-based paint out, you can try adding as little water as possible before adding any liquid. Mix the can properly after adding an ounce or two of water. Next, you can gradually add water to reach the right consistency.  

Can I solve the problem of too thin paint?
