Know the cracks before fixing
The cracks that we normally find will occur on the wall and folk. But the point that the homeowner saw and felt the most displeasure would be the wall because the walls are generally smooth and wide at the eye level of the residents. Therefore, makes it possible to see cracks clearly. The shapes of the cracks that we found there are 4 large forms: sesame cracking, oblique cracks at the head of the pillars, vertical cracks, and horizontal cracks which have both impact on the structure without any impact or danger.
What kind of cracks are not dangerous?
It is normal for homeowners to see cracks and feel anxiety. Because you’re not sure what cracks will affect the stability of the house. Observe the simple differences that cracks that do not affect the structure will not have a clear pattern is a small crack line similar to the map or lightning line. The lines will not expand quickly until it feels abnormal. With a depth not more than 1-2 cm, which is only the depth of the plastered surface. These fractures may be scattered throughout the wall or at one point. Although this type of cracks will not affect the strength of the house. But will inevitably cause the house wall to look unattractive And when the rain splashed into the wall, water may also seep through these cracks.
The reasons that cause these small cracks are usually caused by the lack of knowledge and experience in construction work, such as improper mixing ratio of plaster, before plastering, may not have enough water on the wall surface or allow the air to be in condition that is very dry, causing the plaster to dry quickly until it shrinks, breaks into sesame patterns, or if there is a crack in the corner of the window and door, usually caused by not attaching a chicken cage on the posts, ligaments, lintels etc.
Fix small cracks by yourself with putty
For small and deep cracks, clean the surface neatly, no dust, not wet, then use waterproofing materials or putty, polyurethane or acrylic with high flexibility which can cover the skin over the cracks immediately. Once dry Painted over (If using silicone to fill in cracks, cannot be painted over).
In case of of deep or very wide cracks, you may have to extract the wall by using an old paint scraper around all the cracks first. Then use the material to crack, inject, fill in, start from the point of the largest crack first, and then gradually move to a small spot, leaving to dry. When dry, sand the excess sandpaper and paint with primer for old plaster. Then painted over again The painting of the new wall will make the cracked lines look smoother as if never had such cracks before.
Peeling wall, make the house unsightly
Apart from the cracks on the walls, the peeling paint is an aneurysm problem, which is equally frustrating for homeowners. The main cause of peeling paint, may be from the surface of the wall with high humidity or use of quality paint that is not standard. Causing the color to not stick well. The peeling paint is often a sheet cracked into a loose powder. In addition, to reducing the beauty of the wall and causing dust as well.
Few steps for solving peeling problem
The process of painting an old wall is slightly different to a new wall. By the old wall house, scrape the original color first, clean the wall smooth and free of dust and wait until the wall is dry. Then primer using only primer for the old plaster color then painted over as needed.
However, if the cause of the peeling is caused by moisture, it is important to solve problems at the root cause, such as moisture caused by leaking roofs, top-level bathroom floors or external walls with cracks. These problems tend to cause moisture to accumulate. Even if the paint was painted again, the color would soon peel off again as before. Therefore, it is necessary to always leak various cracks first. In case of leakage from the bathroom floor or concrete roof, use a waterproofing solution. The cracks on the wall can be fixed using the above methods.
Then paint the wall with the product “Moisture Guard primer” or Moisture Guard, water block. This type of solution will help prevent moisture well. Then wait for the surface to dry for 4-8 hours (or as specified by each brand), followed by old plastering primer, increase adhesion of new topcoat paint. You should use water formulas that are less pungent odor and safer than oil formulas. When the wall surface is completely dry, then coat with new acrylic paint or color that the moisture can drain out 2 times.
The problem of cracking and peeling is a small problem, but it can also become a weak spot for the house. Which can be resolved by yourself or if you don’t want to be tired, you can call a technician to take care of it.

But if there are other types of cracks or are unsure whether the cracks will have any effect on the structure of the house or not, you should consult an expert engineer to inspect. Do not leave it as it may be harmful to home and the residents.
