What Causes Spray Paint To Wrinkle?

Have you just got into painting and really enjoy working with spray paint which often forms wrinkles? This wrinkling and rough appearance can ruin the artwork as well as your mood. A layer or skin is formed by the pigment which is uncured in most cases. Spray paints are widely popular and people apply them on multiple surfaces and this is the major problem faced by many. There can be one of the several underlying causes of this unpleasant experience which can be avoided when you detect a fault in painting activity.

Among main factors that result in wrinkling in paint when you spray it on a surface, a common cause is applying a significantly thick coat first and then spraying a second layer. It results in drying of the second layer early while the base coat is still drying.

In this piece of writing, I have listed some common and major problems that usually go unnoticed and produce undesired outcomes. Once you are aware of the cause, you won’t let it repeat the next time. I hope you will effortlessly complete your project and blow your fellows away﹗

5 Main Causes Of Wrinkling In Spray Paint:-

Using A Thick Coat For Application:

Though spray paints include less effort and care than that associated with the paint boxes and brushes, one still can mess up and see a messy wasted object. If the liquid you are about to coat a surface with is extremely heavy, it can result in the formation of wrinkles when the paint dries later.

Thick layer,which will take more time to dry, will not be able to set and get enough exposure. Moreover, the weight of the paint increases in this case and results in its sagging, which in turn contributes to wrinkles. Therefore, It is essential to apply more than one coat and keep in mind to use thin layers of paint every time. Let one coat dry completely before spraying another.

Not Allowing The First Coat To Dry:

When the first layer of spray paint is given insufficient time to dry effectively and the second layer is applied, it will result in wrinkles as well as an unsmooth texture. Any paint contains solvents as well as agents that help it adhere while drying the pigment.

Since both layers are wet in this case, the agents in the second one will incorporate with the first coat and form a semi-solid material. Before drying, it will form bonding with this liquid substrate and hence will not properly adhere which is a necessary requirement. Thus, you will notice wrinkles in the upper coat when it dries thoroughly.

Painting On An Unclean Surface:

The key point to avoid the art project while spraying paint from an unsuccessful outcome is to keep the target surface clean. Cleaning the surface before beginning is important since it also facilitates the efficient drying. Usually, an object or wall has some solvent or other polishing and cleaning liquids on it which is ignored before painting.

These chemicals can form unstable products after mixing with the components in spray paint. It will eventually mar a project. I hope you check the surfaces for your coming tasks and only start when you are satisfied that they are free from any residues.

Extreme Weather Conditions:

Either you have heard the forecast for a rainy day or it is the time for hot summer treats in your area, you should keep yourself from spray painting. I know it is a bit difficult to control yourself especially when friends are coming over. However, you will realize it is worth it as the harsh atmospheric conditions also contribute to damaging the coatings or overdrying it.

In case of significant humidity level, the paint will not get a chance to set on the surface properly, causing wrinkles. On the other hand, too much sunlight can dry the pigment excessively and cause it to form uneven layers on the project. Hence, it is essential to take care of this outdoor aspect before thinking of any paint-related activity.

Unsuitable Product Combination:

The prior knowledge of types of primers, solvents and paints is highly necessary in achieving the goal of fantastic design. A variety of paints are available in the market that differ in ingredients. Some are oil or acrylic based while others are water or milk paints. Another category contains lacquer as a carrier while the other has epoxy compounds as their main solvent.

Water-based paints generally dry quickly. Applying a lacquer-based layer on these kinds of paints will not help as the driers in this second coat will possibly react with the first one. So it will not get an appropriate surface to bond with and ultimately form a wrinkled pigment layer.

Thus, one should learn about the properties of base finishes, solvents, and carriers in order to create a perfect match after choosing the items that work the best in coordination.

Frequently Asked Questions About Paints:-

How do you know if spray paint is expired?

Generally, the time period mentioned on the lower portion of a spray paint can help in determining the expiry date for the product. This range usually lies between 5-10 years. Some major signs that show that paint should not be used further include hardening of the paint and reduced can pressure.

Are spray paints permanent?

As you spray paint on a surface, the water and volatile compounds will evaporate and a firm film will stay. The pigmentation is permanent and allows artists to apply multiple coatings on the base layer.

Should I prime before spray painting metal?

Yes, it is recommended to use a primer on the metal surface where you want to paint. It helps the paint improve its adhesive property as well as protect the metal from corrosion.

Final Thoughts:-

Spray painting is a fun activity that keeps a person engaged. It also makes the aimed objects and items visually appealing. One can face a problem of wrinkle formation anytime if some trivial step is not suitable. This post mentions all details regarding the possible causes of this common occurrence, the awareness of which will hopefully prove beneficial.
