Every consumer looking to apply paint instead of using a screen faces the choice between projector paint acrylic vs enamel. You may find that the best projectors offer various options for a smooth surface to watch content on because many projectors require only a flat surface. However, there are some considerations when choosing paint if you want to paint the wall for your screen. These include safety, application, cleaning, drying, durability, and reflectivity for both short throws vs. long throw projectors.
One of the biggest influencers when picking paint should be your safety. It’s easy to forget that some paints use materials that are toxic to humans. For example, acrylic paint is generally considered safer because of its water-based composition that causes little smell. Additionally, its components do not contain any toxics, unlike enamel paints. However, these oil-based paints feature a strong smell for an extended period, and some of their components can pose health risks to users. This factor has a big influence on schools looking to get a smartboard vs. an interactive projector.
Acrylic paints do not contain toxins and have little smell, unlike enamel paints.
When it comes to applying your paint, enamel becomes the easier to use option. However, this is one of its few advantages. Enamel paint can be messy if you aren’t careful or aren’t applying it correctly. However, enamel does go on uniformly, providing a better experience. Acrylic paint can be challenging to apply evenly. Because of this factor, acrylic paint has noticeable strokes of brushes on a flat surface, and two coats are often needed. Finally, acrylic paint can be cleaned off using soapy water even after drying due to its water base, unlike sticky enamel paints.
Acrylic has inherently better drying times with a quick-drying composition, allowing users to apply as many coats as they desire in a shorter time. On the other hand, enamel paints can take hours to a day to dry, and the smell lingers longer than that time frame. Therefore, if you need to apply multiple coats of enamel paint, you should wait for the last coat to dry before starting the next one. As a result, this process could take days when using enamel paint.
Acrylic paints are inherently more matte than their enamel counterparts, meaning they are flat and do not reflect much light. As a result, they eliminate the chance for projector images to reflect too much, which causes disturbance and blurriness of the content. If you find that your wall absorbs the colors more than reflects them, you can apply a finish to make the wall slightly shinier. On the other hand, enamel paints feature a glossy finish, though mixing in a medium matte color may help.
If you are going to be using your projector outside, you will need to pick a paint that can withstand the heat and sun outdoors. Because of this exposure, you most likely want to purchase acrylic paint since it is more flexible and does not crack in the sunlight. Although they do swell in moist climates, acrylic paint remains a better option than enamel, which does crack in the sun and has low flexibility.
Acrylic paints cause dust to stick to the flat surface of the wall, but they can be cleaned easily with soap and water.
What type of paint should I use for a projector screen?
You want to use acrylic paint as it is faster drying, more durable, and has the right reflectivity for projector use. You will want gray, black, or white paints with a smooth finish.
Can you use enamel and acrylic paint together?
You should not mix enamel and acrylic paints because of the difference in their components, with enamel being an oil paint and acrylic being water-based. As with oil and water, a mixture of the two paints could separate.
Is acrylic the same as acrylic enamel?
No, acrylic enamel paint forms a hard shell once dry and is mainly used for cars, metal, and wood.
STAT: Glossy paints are shiny and reflect most light in the specular (mirror-like) direction, while on flat paints most of the light diffuses in a range of angles. (source)
