Painting the house is considered an important step to help a building look aesthetically pleasing and protect the house from the impact of the environment. However, lots of DIY painters and other contractors wonder how many layers of house paint are enough? or how many coats of primer are needed? to achieve perfect color and a smooth surface for exterior painting.
If you need more information about exterior painting and anything related to getting your paint job done, just keep reading the article below we will answer all your question about house painting and help you to have stunning and quality paint.
Is One coat of paint enough for exterior painting?
Many people may embrace the ideas that applying one coat of paint is enough for their houses’ walls as it is more economical both in the cost of labor workers and the amount of paint needed. However, in this case the quality is matter more than the quantity, specifically:
For new walls, never been painted:
The new cement layer always has the dark color of the cement, and the surface is rough, so even though it has been painted with 1 or 2 coats of primer, the color coverage of the primer layer won’t still cover the dark part of the wall.
When applying the first coat:
If we only paint 1 layer: the paint layer will not cover evenly and be unable to cover the darken tone of the foundation, making the wall will not have the aesthetic and dedicated beauty.
Moreover, one coat of paint will be too thin, making the adhesion to the wall pretty low, which means the quality of durability will not be high.
For Old Wall:
After cleaning the old paint layer, the wall will have an uneven color at this time, so if we only paint 1 coat, the thinness of 1 layer of paint will not evenly cover the wall, resulting in a weak durability as well as aesthetics.
Therefore, in order for the paint to be beautiful, aesthetic and long-lasting, we should paint at least 2 layers or more.
So How Many Coats of Exterior Paint Are Enough?
The number of layers to paint the house depends on the purpose of painting the house, is it repainted or new paint. Or also depends on the type of paint used to paint the house. Moreover, the quality of the paint used can also affect how many painting coats are necessary.
Unfortunately, low quality paint does not cover well and can be a real bother when you need to apply several coats to provide adequate coverage. The pigments, resins, additives, and solids in high quality paint are all superior. So, purchasing higher-quality paint may help you to prevent applying too many layers of cheap quality paint which can even cost more.
All in all, a perfect house painted system needs to ensure a minimum of 3 layers, including 1 coat of primer, and a 2 coat system of paint. Specifically:
This is the layer of paint between the rough part and the top coat. The primer acts as a double-sided tape that adheres the surface to the transition coat. This can prevent the paint from peeling, helping to resist the paint coat from fading caused by chemicals in cement, and have a high resistance to moss and fungus.
2 Painting Coat:
This paint helps to prolong the life of the wall surface, making the house more beautiful over a long period. In addition, the coating also has the effect of anti-fouling, anti-fungus, reducing the chance of patchy paint color in a long run. This basically implies that applying two coats of paint produces a thicker coat, hides better, sticks better, and lasts longer.
Why should you apply more coats to your house painting?
Without a doubt, applying the second coat of paint or multiple coats should be used for exterior painting. It’s hard to cut corners here because outside surfaces are frequently prone to extreme weather and other elements. If a paint job is applied incorrectly, such as by applying only one coat of paint or failing to properly prepare the surface by pressure washing, priming, etc., exterior surfaces are more likely to peel or fade.
Your Painting Will Appear Better
Even though it’s true that some paints are slightly thicker than others and say exactly on the can that only one coat is required, generally speaking, skimping and painting the bulk of the surfaces in your home with only one coat won’t produce the results you’re looking for. Only choosing two coats of paint for your house painting project will give you that luxurious, smooth finish, regardless of the paint type or the surface.
Moreover, many believe that you will only need to use just one coat of a darker hue of paint. These will really be paler than the original hue and appear to be less colored than what you expected, so in these cases, two or three applications will be necessary to allow the beautiful color to fully develop.
Your Painting Will Last Longer
A single coat of paint can last as little as three years. In contrast, if the same surface has received two coats of paint and has been properly primed, its longevity can reach ten years, depending on environmental factors like the elements. When it comes to the parts of the home that you use the most, this might not be such a big deal because it’s likely that you’ll alter the color scheme of your bedroom or living room before the 10 years are up anyways.
Cutting corners and prices will probably only harm you later when you have to start the project over from scratch and pay for it again in a few years.
Enhancing the Surfaces’ Durability
Two coats of paint are significantly more enduring than one, so it’s not just important for appearances. If a wall has been coated twice, whether interior or exterior, it will typically be simpler to clean. A well-applied paint job can endure up to ten years, even in our humid climate. As you can see, the cost of a job well done is definitely worth it!
Why do you need a primed surface before painting?
Primer is a layer of paint with a separate formula, which is applied to the surface of the material before applying the first coat or color paint. Primer helps the surface have good adhesion, supporting the transition paint adheres to the surface of the material.
Therefore, in the process of repainting or painting new walls, primers is a step that should not be skipped. Primer can be used with many optimal utility:
Limiting paint peeling:
Primer acts as a double-sided adhesive tape that attaches the surface to the transition paint. This can help to prevent the color paint from peeling off.
Improve adhesion quality:
Primer with alkali resistance effect commonly found in lime and cement. The wetter the surface, the higher the alkalinity, which easily breaks the paint structure, causing the painting coat to be pale, patchy, or mould. Therefore, the primer layer has the effect of covering the alkaline surface, improving the adhesion quality of the painting layer.
In contrast with the interior painting, the outside walls often have to endure rainny, snowy and others extreme weather which often have high humidity or are waterlogged, the phenomenon of mold appears prequently and causes unsightly surfaces. The primer with antibacterial, and anti-mold features will help the paint structure to be more durable and avoid mould situations.
Create gloss, smooth, evenly colored:
The primer layer helps to increase the thickness of the paint layer, creating gloss and smoothness so that when applying the topcoat on a stable surface, the paint color is more beautiful and even.
The Important of Prime Painting
Primer is a necessary step in the painting process to improve paint quality and surface quality. In fact, paint job using the correct primer rarely occur peeling or discoloration and the surface of the house has very high color fastness.
The reason is that when the primer layer is combined with the painting coats, it will form a super-bonded and tough paint film, helping to resist the negative effects of the weather such as hot sun, humidity, dust, etc. .
If you paint over an old dark wall without using a primer, it will most likely cost more because you have to use multiple coats of paint, or after lots of painting coats, it still does not present the desired color.
Choose a Professional Painting Contractors
Although painting is a relatively simple DIY project that will save you money on labor, it’s always a good idea to have a professional painter on call. It might be time to seek an estimate from a painter close to you if you don’t have much time on hand or have a fear of using a ladder to reach a high spot on your ceiling. Especially, homes with a second story or a complicated roofline can be definitely risky for amateurs to do painting, in this case hiring a professional team will be the best option.
