When painting walls, you must take into account basic elements such as the appropriate amount of paint and the correct preparation of surfaces

Painting walls is a simple job but sometimes may have some doubts and difficulties, especially for the first time who faces a task of such characteristics. This article lists five tips to avoid beginner mistakes when painting the walls of the house, from the common faults when loading the brush or roller with paint too scarce or abundant, to the importance of preparing the surfaces properly and leave dry the paint long enough.

Painting the walls is not a complex task. It does not require specific knowledge or skill. But it can happen that, during development work, some questions arise related problems or unexpected setbacks. These, often, are due to small errors or lack of foresight, especially because of lack of experience. In any case, they are, in general, simple to avoid.

  • Do not overload brush or roller

This is a mistake that is usually caused by the rush or anxiety to finish the job fast. The result is that the appearance of the painting on the wall is not smooth, but as if it had folds or was “wrinkled”. Therefore, do not overload the work tool.

The correct method is, after wetting the brush or roller in the paint, to let drain well so that excess fall and not be carried to the wall. If using brush, you can pass either side by the edge of the pot or bucket of paint, to remove excess. If instead the tool used is a roller, the use is recommended of trays designed to facilitate work and optimize the performance of the paint.

A sign that is charging too much brush or roller painting is that too much ground splattering paint. Some splashes are normal, but if every time the tool gets wet in the paint will cause new stains, greater precautions must be taken.

  • Do not load too little brush or roller

This is the opposite problem to that described above. It may be caused by the feeling (or certainty) that the available paint will not be enough to complete the work, or the simple spirit of saving. What you get is a wall where the paint is or marks channels, especially when painted with a brush, as there are bristles are exposed (dry) and scratch the surface.

It is important, therefore, to obtain good results, use the right amount of paint. And if you do not have enough to cover the entire surface to be painted, it is best to reduce the work area (can be painting only one wall instead of two) or wait to have all the necessary material.

  • Prepare surfaces thoroughly before painting

As important as the way the paint is applied is the pre-conditioning of the surface on which it is to be worked. To this are several key steps: stripping and sanding well the walls, especially if they had a very old painting; apply a good primer; and make sure the walls are dry. If these precautions are not taken, the painter will have the feeling that the paint does not adhere, the finish will not look quite right and, after a long time, it is likely that the paint will start to rise.

  • Pay attention to the compatibilities between the products used

This issue may seem minor or unnoticed, but if the primer, sealants, paints, lacquers, varnishes , etc., are incompatible with each other, one or more of these layers will eventually cracking and surface visible slits are made and other Irregularities.

  • Let the paint dry long enough

It seems obvious, but often the lack of patience leads to a hand painting on a previous one that is not yet completely dry. This happens by simple haste, or because it has already passed the indicated time as recommended but nevertheless, by some factor, the painting has not dried enough. It can also interfere with the ignorance of believing that the new layer can be applied and then dried together.
