Why is my spray paint sticky

If you do not clean your spray paint can and use it for a long time, the paint will become sticky. This is because the paint has an organic solvent in it that evaporates with time.

So, if you don’t clean and leave the can open, the paint will become sticky because the solvent evaporates.

The best way to ensure that your spray paint doesn’t get sticky is to use the paint quickly after you open the can before the solvent evaporates.

You can also clean the can to remove any paint residue and keep the can closed. This will help the solvent from evaporating.

This is because of the humidity. Spray paint is a solvent-based product, which is also referred to as lacquer. Solvents are hygroscopic.

This simply means that they can absorb water. The higher the humidity, the more likely lacquer products will become sticky. If you spray a few cans, your cans will become sticky very fast.

To make sure you have a smooth application, it is important to make sure all of the cans you are using are at the same temperature.

If you have cans that are in the shade and cans that are in the sun it is best to let you can warm up to room temperature.

Ways to make spray paint less sticky


To eliminate the stickiness of spray paint, you need to use a primer. The primer will make the surface of the wooden, metal, or other materials.

Which is the first layer of the spray paint bond, thus making it less sticky. You can apply primer with a brush or a roller. Note that the primer layer is very thin.

Shake the can properly

When spray paint is sprayed without being shaken, it produces uneven paint covers. This happens because the paint settles at the bottom of the can.

In order to have an even paint cover, you should shake the can. This will ensure the paints are mixed evenly in the can.

Perfecting first coat

If you really want to reduce the stickiness of spray paint first coat, start with what you could get your hands on. A sound coat of primer will really help you to avoid sticking mistakes.

You can try this using a spray primer; thin coat and sandwich over with a couple of layered coats to form a nice base.

If you are going to use a plastic primer, make sure you mix it up first, then shake well and spray when the nozzle is still.

As a second step, use water-based paint evenly on all surfaces which are not covered with primer. Remember, rushing can cause major errors in the process.

Work slowly and allow the paint to settle. After this, the second coat of primer is recommended before you start painting. This will help you to produce a flat surface that is less likely to stick.

Use talcum powder

Spraying a layer of Talcum powder before spraying paint is a hack that many professional painters and car bodyworkers use for reducing the thickness of spray paint.

Talcum Powder acts as a skin to your wet paint and helps it not stick to the surface. There are many uses of Talcum powder in daily life, and it’s good to know them.

It is a good idea to keep some Talcum powder handy in your car at the time of car paint jobs.

Check humidity and temperature levels

To avoid this from happening, spray your paints outside in fresh air to decrease humidity and temperature.

Spray paints are more likely to leave behind a sticky residue when the temperature is at a level that is too low or too high.

Therefore, it is best to spray your paints on a surface where the temperature is between 50-80 degrees Fahrenheit.

Furthermore, you may also want to try shaking the can before you spray your paints, in order to distribute the paint evenly in the spray.

Additionally, you may also want to consider using a specific spray paint-resistant primer to paint on, as these primers are formulated with the purpose of reducing paint sickness.

Baking soda

First of all, the spray paint should be allowed to dry a little before applying the baking soda. Now you get a rag and dip it into the baking soda.

Wipe off the excess and then gently rub it over the sticky surface. Yes, it will work if you work it gently and fast.

Causes of spray paint sticky

Here are some common causes of spray paint sticky issues which newbies face often in their painting career. But I have mentioned the fixes above In this post to help those who are caught in this issue.

Nozzle spitting

causes of spray paint sticky

When using spray paint, often times the nozzle can be blocked or clogged with dried-up paint. If this occurs, simply use a toothpick.

Preferably the one that was included in the box with the spray paint- to push out any blockages and continue using your spray paint!

Most spray paints come with an agitator ball that helps to mix up the product when you shake the can. If you don’t shake it enough.

The paint won’t be thoroughly mixed, and it will come out looking splotchy and messy instead of smooth and even like a real professional would have done it.

Nozzle clogging

Even the best of us sometimes get caught in a spray paint clog. When using cans of spray paint, you might encounter a problem where the nozzle gets clogged and prevents you from getting any more paint out.

There are several reasons for this, including not shaking the can well enough before spraying, or your paint picking up some particles as it is used.

A quick solution to this problem is to remove the nozzle from the can and place it in lacquer thinners to dissolve away any blockages.

If you run into another spray paint mess-up, swap nozzles with an extra can of paint so that you do not have to waste time by cleaning them off individually!

Applied too much paint

One of the mistakes you could make when putting up wallpaper is to stick on too much of it at once. In some areas, there’s a big smudge, particularly on the edges towards the top.

These areas will take longer to dry than other areas, and if a second lot is put on top of that, then what happens is that the first bit hadn’t been enough time.

To dry properly stick to the bottom layer as it wasn’t finished yet. So, when the second layer goes over, then it makes this mark that is sticky if you touch these bits.

Spray in shade

Working in a cool, shady area or waiting for the sun to go down is always a good idea when it comes down to spray paint.

Painting on plastic surfaces can also affect their pliability depending on whether the weather’s warm or colder. Using heat-sensitive paint products can cause problems with texture and take longer than usual to dry.

So make sure you’re wearing something that has some shade and use cold-weather paints when possible since they tend to work with plastic surfaces much better than hot-weather paints.

So be careful choosing where you’ll take your spray-painting session. You don’t want to overheat or in any way, risk damaging the plasticizers in your paint cans.

So it’s best to avoid direct sunlight, where the temperature can easily climb as hot as 150° F when doing painting in the summertime.


The tacky spray paint does dry eventually. It takes about an hour to completely dry. This is actually a good way of saving time. You can save many minutes or even hours if you spray paint something at night and if you need to paint the same object again the next day, it won’t take long to dry.

Treating tacky paint isn’t a difficult task, but it will take time and effort. All you have to do is find the paint that dries fast, but won’t cause damage to the surface that you are going to paint. I’m sure you have heard of shellac. It is an alcohol based liquid which dries very quickly and doesn’t cause any damage to the surface. It is also used as a sealant and a drying agent, as well as a polish. You can spray it on the surface you intend to paint and let it dry before applying the first coat. It will prevent the paint from chipping and peeling later on and in case you don’t want to use it, you can just get a tarpaulin and cover the furniture/object and allow it to dry.

First you need to let the spray paint dry. You can harden spray paint by putting it in a refrigerator. Spray paint dries fastest in a colder environment, and if you put it in the refrigerator, it can harden faster.

To harden spray paint before using, the best thing to do is spray the paint on a cardboard box. Spray the paint on all sides of the cardboard, until it is completely saturated. Once it is saturated, it will be really tough. If you want to paint something, you can grab the cardboard and use it as a stencil.

Semi gloss paint is sticky because of the compound used in it. It mainly contains Polyurethane and Varnish which makes it difficult to get dried. Peeling and sticking is a common issue among semi gloss paint.
