Why do you paint your building?
It’s never the same reason for different people. But one thing for sure is aesthetics. Others also paint to protect the surfaces from damage.
To achieve this, especially the latter, applying a primer first is usually recommended.
Unfortunately, this step is usually disregarded more often than not, which is understandable since not many people know its benefits. But here’s why you should start considering it.
A primer is simply paint without pigment.
Its main purpose is to create a better adhesion with the surface being painted and the paint itself. This increases the durability and life expectancy of the paint film.
A primer also performs the following functions:
- It reduces the amount of paint being absorbed by the original surface
- Seals off small defects and joints on the surface being painted
- In exterior painting, a primer minimizes cracking and prevents mildew growth
- It also protects masonry surfaces from the effects of efflorescence and alkalinity
Paint on the other hand is pigmented, it basically performs most functions a primer does. But for the paint to last long on a surface, priming is necessary.
An unprimed surface will crack and peel off in months.
So, yes priming before painting is absolutely necessary.
Application tips for pre-painting and priming services
For a perfect finish, the primer should be applied to a clean and dry surface. And after the application, the primer should be left to dry for a few days before applying paint.
If you’re painting a deteriorated surface, it ought to be cleaned and smoothed out before applying a primer.
It is also worth noting that primer paint fumes may be toxic, so if it’s an interior painting job, ensure you let all windows and doors open for adequate ventilation.
As much as you may want to carry out the painting job on your own, trusting a professional to do it can be your best chance at achieving a perfect finish.
You can also simply consult with a professional and do the work yourself.
