Well, if you don’t know the reason behind it, you won’t be able to help yourself finding ways of “how to fix wrinkled spray paint”. So, as a starter step, let’s find out- why does spray paint wrinkle and we will answer all additional questions while we move forward.

What Causes Spray Paint To Wrinkle?

Many factors, including the grade of the spray paint, the type of object you’re painting, and other characteristics of the environment, might lead the spray paint to wrinkle.Let’s discuss all the factors in brief.

Thick Single Coating

The rapidity with which spray paint is applied is an advantage. The painter does not have to bother about paint brushes, filthy solvents, or open cans that may tip over. With the ease of use of spray paint comes the assumption that the paint could be sprayed in a single hefty layer.

Thick Single Coating

This is a false assumption. Spray paint must be sprayed in several thin layers, each of which should be allowed to dry fully before adding more coats. If a single thick layer of spray paint is sprayed, the weight of the paint could be too considerable, causing the paint to wrinkle or droop as it dries.

Contaminated Surface

Surface contamination is another cause of wrinkling sprayed-on paint. Spray paint must be applied to a clean, dry, and prepared surface for it to dry correctly.

If the surface is polluted by a solvent or cleaner film left over from the surface preparation procedures, the residues can react with the spray paint carriers, leading the spray paint to wrinkle as it dries. Before repainting, the paint must be cleaned and the surface re-cleaned.

Contaminated Surface

To remove water-soluble filth, use detergent and water. To remove greasy impurities, use wax and grease removers, followed by a final clean-up with isopropyl alcohol to eliminate any leftover pollutants.

Not Enough Drying Time

If a first layer of spray paint is not enabled to cure well before applying the second coat, the solvent and curing agents in the subsequent coat of paint might weaken the tough outer of the first coat. It will result in a slimy, unstable surface.

As a consequence, the subsequent coat tries to attach to a brittle substrate. The topcoat creases in this scenario due to a loss of adherence to the object’s surface.

Environmental Factor

Wrinkles can also be caused by extreme temperatures. Painting outside in the blazing summer sun can generate spray paint wrinkles.

When the temperature is too hot, spray painting anything outside increases the likelihood that the exterior coating of the paint layer will dry quicker than the inner surface coat, resulting in spray paint wrinkling.

Furthermore, paint which has not been entirely dried and has been exposed to high moisture, rainfall, or mist could stretch and wrinkle.

Apply a coating of primer following sanding and dusting to provide a consistent ground for spray painting. The primer assists in the adherence of the paint. After spraying the very first layer of primer, we should wait 4-6 hours for it to dry.

Make sure the previous coating of the primer is completely dry before spraying the second coat. Otherwise, the paint will not be able to resolve since it is too fluid. When you’re through priming, don’t forget to sand and clean the primed surface again for smoother results.

Step 5

Select the appropriate spray paint quality for your job. High-quality paint may provide a long-lasting coating. Spray a light layer of paint on the area from at least 12 inches away. Don’t be concerned if you overlook any locations. You’ll have more time to deal with this later. Let 3-5 hours for the paint to thoroughly cure before touching it.

Two coats of paint are considered the industry minimum in spray painting. When you apply the initial layer, you will be able to cover the largest surface area feasible. With the next layer of paint, you may cover up any leftover areas that you couldn’t paint in your first attempt.


How many coats of spray paint are needed?

When spray painting any item, the number of applications required for full coverage is at least two light coats, maybe three, done at varied angles to ensure complete coverage.

How long to let primer dry before spray painting?

The amount of time you need to wait for primer to dry prior to painting an item varies depending on the kind of spray paint you use. Whenever the primer is entirely dry, this is the best moment. If you applied the recommended thin coat, it should dry in an hour or less, but check the spray paint can tag to be sure. In hot and humid weather, drying time will be longer.

How to Seal Spray Paint?

If you apply a high gloss or semi-gloss finish and want a glossy look, you don’t need to seal it. If you want a lesser sheen, use a liquid sealant like Minwax Polycrylic.
