Cracking walls aren’t just a problem for plaster – even the most expensive, high-quality interior paints can exhibit a similar flaw. Fortunately, there are solutions to fix it properly and ensure it doesn’t happen again.
So, what are the causes of the paint cracking on wall, and how can you correct it? Read on to find out everything you need to know about paint cracking.
Poor Quality of Paint Used
Lower-quality paint will not adhere correctly to surfaces, which can cause the paint to crack and/or bubble over time. Poor-quality paint is often either too thin or is formulated with cheaper ingredients, resulting in low-grade paint with poor longevity.
One way to prevent paint cracking is to invest in high-quality paint. It will last longer and adhere better to the wall, therefore preventing cracking paint problems.
Excessive Expansion and Contraction of Walls
Abrupt wall movements due to seasonal changes in temperature and humidity can fracture a rigid paint film. This leaves unsightly cracks and separations across the surface.
To fix this, the paint used should be flexible to allow for some expansion and contraction without rupturing. Low-VOC paints are also recommended as they are designed to expand and contract with temperature and humidity changes.
Repairing existing cracks and chips before any painting can help slow and possibly halt any further damage.
Not Applying a Primer
Primer acts as a binding agent between the wall surface and the paint layers. A wall’s texture is often uneven and primer can smooth out those surfaces for even painting. Without primer, any cracks or gaps will show up in the paint job and will eventually crack.
To fix this, repairs such as sanding, gouging, and scraping will need to be done to prepare the wall surface. Afterward, a primer should be applied to create an even waterproof surface.
Not Curing Before Reapplying Latex Paint
Latex paint needs at least 24 hours of drying time before applying another layer. This curing time allows the latex paint to form a skin on the wall, allowing for a better-finished look. If the latex paint is reapplied before curing, the surface layer of paint cannot adhere to the wall properly, resulting in cracking.
To fix this problem, the damaged area must be sanded down and prepped again for a new coat of paint.
Unsuitable Undercoat or Sealer for the Wall Surface
With unsuitable undercoats or sealers on the wall surface, the wall may not be able to sustain the size and weight of the oil or latex-based paints, and the walls can end up cracking.
To fix this, start the process by completely cleaning the wall surface. After it is dried, a suitable undercoat must then be applied. A contract-grade sealer must be used to make sure that it is adequate for the task.
