Doing a paint job is not rocket science in any manner. Although you do need to know how to mix the paint with oil and the ratio in which both these paints need to be mixed, it is not that hard to paint a part of your house without hiring a professional painter. Here are the key steps which you need to take to paint the outdoor walls of your house.
Remove the old paint
If you apply a new layer of paint on a wall without removing the old layer, it would never produce a smooth finish. Use a trowel for this purpose. Before applying primer, you should be sure that the old paint layer has been removed.
Choose a paint brand with moisture protection
When you are choosing a paint brand for outdoor painting, it should provide protection against moisture and sunlight. If there is no moisture protection, the paint would lose color at a faster rate than usual. In addition to that, this would result in cracks.
Wait for the first layer to dry
When you are applying a paint layer on an outside wall, two layers of paint would be applied. However, it is important that the first layer dries completely before the second layer is applied. Ideally, it takes about 6 to 7 hours for a paint layer to dry completely. Once it has dried, you can apply the second layer of paint. If your wall is very rough in terms of texture, apply a third layer for smooth finish.
Use a roller brush
There is no doubt that a roller brush gives a smoother finish than a normal conventional brush. You can also use a combination of both. Apply the first layer with the conventional brush and then the second layer with a roller brush.
