It is no secret that spray painting during winter and cold weather is impractical. However, some situations mandate that you do it, meaning that you have to find the best way out of it. Very cold temperatures affect the thickness of the paint film, leading to tiny bumps during the coating process. So, how can you achieve a perfect paint job during the freezing winter months?
Pre-painting Preparation is Vital
Make sure you clear the spray gun totally before and after use. Low temperatures lead to build-up of ice in the spray gun during storage. The ice can lead to clogging and jamming during spray painting. You also need to prep the surface. Make sure to remove the moisture from the target surface completely before applying the first coat. If the surface is frosty, scrap the frost off totally and wipe the surface with a cloth.
Be Innovative With the Paint
During cold weather, paint becomes thick and might not flow properly. This can give you an ugly orange peel if you don’t become innovative. Now that you MUST spray paint during these low temperatures, try to warm the paint in a pan of warm water in an enclosed area. Quickly do the outdoor painting job and take the paint back inside the house or garage. Repeat the process for additional coats. You can also try to warm the part that you are painting using your hair drier.
You can as well turn on your heater if you are painting the indoors. This is true for painting jobs involving cabinets, furniture and walls. You can use a high-watt (500+) halogen bulb that produces heat and light.
Most people make a mistake of adding thinner to the viscous paint to make it lighter. This is a wrong solution because it can lead to orange peel. Adding more coats is also not a solution, and can lead to blistering.
Maintain High Quality
Just the way you spray paint during summer, high quality tools and materials are critical during winter as well. Paint Smoothly points you in the right direction when it comes to getting the right spray painter. Make sure you use enamel paint as opposed to lacquer.
It is not advisable to spray paint during freezing temperatures, but when you MUST do it, make sure you use a high-end spray gun and proper paint. Use warm paint to prevent orange peel. You also need to clean the surface thoroughly before applying the paint. Keep your heater on if you are spray-painting indoors.
