Let's first know what the causes of paint problems and peeling home walls are.

What causes peeling walls?

Another problem that makes many people worried is the walls of their homes peeling off. In addition to making the house look dull and unattractive, it may also cause big problems that are too difficult to solve. The main reasons why house paint peels off are as follows:

Houses have been built for a long time, causing them to deteriorate with age.
Changing weather conditions including sun, wind, and rain all cause problems with paint peeling off and cracking.
The painter does not have the expertise to use materials and equipment that are not of good quality. Or maybe you didn't apply the primer before applying the topcoat.

Type of primer

New cement primer: Paint used for new construction areas. Before applying the new cement primer, the wall must be dry for at least 30 days.
Old cement primer: Paint used for applying old cement primer. Simply put, it is used on walls that have been painted before. Before painting the primer on the old cement floor, the area must be cleared and the surface cleaned. Otherwise, the color performance will not be as effective as it should be.
Multi-purpose primer: developed to be able to be used on both new and old cement floors. This type of primer is a quality brand that can withstand high humidity up to 40% and has good adhesion. You can also apply it on newly plastered cement that has been left to dry for just 7 days, no need to wait 30 days for moisture to escape.

Tips for choosing a primer

The first thing is to notice what kind of cement the wall we want to use is, whether it has just been plastered, whether it has been plastered for a long time, or if it has been previously painted in order to evaluate the correct use of the primer. It is divided into 3 types according to the type of foundation color as follows:

New cement primer: Suitable for houses that have just been built, have just been plastered and allowed the cement to release alkali for a complete period of approximately 30 days. The main function of new cement primer is to help prevent alkalis.
Old cement primer: Some users may call it “Old cement primer”. Its appearance is a clear oil that can penetrate and adhere well to the surface. Helps lock chalk dust and paint film scraps to adhere to the surface. It doesn't come off and disturb you.
Multi-purpose primer: suitable for houses that need urgent painting. This is because some construction projects may not be able to wait for the 30-day period for the lye-discharging cement, or for some projects, old cement walls may need to be painted quickly. However, if it is to be used with old cement, it may be suitable for cement that has not deteriorated much.
