Why Does Spray Paint Crackle? & Spray Paint Crackle Effect
There are many significant reasons behind the spray paint crackle effect, but the temperature is at the top. You will notice paint cracking when the temperature is too hot or cold. The reason is that the adhesive effect of paint alters with the change in temperature. The upper layer dries quickly, and the bottom layer remains wet, causing cracks.
Another cause is the moisture which is also created due to temperature change. When it’s too hot outside, the upper paint layer gets dried quickly, leaving behind the wet paint. As the crackle is exposed due to temperature; therefore it’s crucial to use a paint sprayer at optimal temperature ranges.
Likewise, it happens when you are in a hurry and applies a second coat without waiting for the previous coat to dry. Suppose you are using a combination of two paints and don’t mix properly, you have to face such problems.
Therefore, professionals always recommend you prepare the surface before spray painting. Check all the cracks, damages, and clean the surface from any debris. Use primer when it is necessary and don’t apply a second coat before it dries. If you follow these procedures, the spray paint crackle effect will not be an issue.
How To Fix Spray Paint Crackle – Easy Steps
You can fix spray paint crackles for all kinds of surfaces by following the easy steps mentioned below:
Step 1: Preparation
Whenever you start spray painting, preparation is necessary. As you know that it release the toxic fumes which can be dangerous after breathing. Therefore, make sure to wear a quality face mask. Always check the ventilation and open all the windows to get the air passed. Try to create a less humid or cooler environment to get the best paint adhesion and drying.
Step 2: Sanding
When you are trying to paint an already painted surface, it helps cover the damages and make the surface smooth. Buy finely-grained sandpaper and rub all the damaged areas carefully. After sanding, clean the surface with a smooth or wet cloth.
Step 3: Use Primer (Optional)
A primer is the best compound to use for consistent and even coverage. The manufacturers are manufacturing specialized primers for spray painting projects. Use a roller or a paint brush to apply primer. Make sure the primer gets dried before spray painting. We recommend you give a few hours gap or at least one day if you have enough time to complete the project. It will surely help you get the cracking-free spray painting on any surface.
Step 4: Apply Only High-Quality Paint
Good-quality paint is also a reason to get high-quality results. You can buy paint from top-notch brands such as Krylon, Zinsser, and more. Don’t forget to check your painting requirements, and you will easily find an affordable solution.
Ensure painting with the help of thin paint, don’t go for a thick paint. Mix the oil or water in the right proportion to get thin paint. Apply at optimal speed and a reasonable distance to get an even finish.
Step 5: Apply Coats Carefully
It’s important to know how many coats are required for your painting project. The answer depends on many factors, such as the type of paint, the surface, and how you apply the paint. The brand also affects the number of coats; therefore, carefully choose the spray paint brand.
According to our experience, two coats establish good adhesion and solid color. We also recommend using two coats for long-lasting performance.
Step 6: Wait Before The Next Coat
Don’t apply the second coat in a hurry. Wait for a few hours; otherwise, waiting for about 24 hours reduces the chances of paint cracking. Further, read the manufacturer’s instructions to know the exact waiting time. The reason is that you can prevent cracking when the area is ventilated, cool, and the surface is dried. When the environment is humid or damped, they increase the chance of cracking.
