How To Paint External Walls

It is clear that it is the exteriors that suffer the severity of the weather and are in constant exposure to the sun, that is why we must choose suitable paintings to prolong the good appearance of our walls and thus the beauty of our house.

Surface Preparation
In the exterior walls, you can not use the mastics that are used indoors because they would not resist the rains and other atmospheric factors. There are special filters for exteriors, but there is no doubt that cement is the best solution.

A widespread problem is moisture in walls, which appears breaking the plaster or coating that is adhered to the wall on the outside. In this case, you can add to the patches you make certain anti-moisture compounds such as water repellent in the paste, or similar materials. The application form varies, and you will find it in the product packaging.

Once the fixes have dried remove the paint detached from the surface, and sand the wall with sandpaper 60 or 80 to remove previous colors or plaster grains in new walls. If it has any texture or is just too rough to be sanded, just brushes to remove all the dust, it might have. There will be no need to sand it.

Whether a new wall or previously painted, you should apply a prior coat of sealant fixative or products of similar characteristics, so that it does not absorb too much paint and fixes better.

Tools to use
Remember to cover the floor and proceed to paint. It is best to use a full roller and the use of the pole, and brush or brush to cut. If the wall is textured or with a very thick plaster, i.e., with many imperfections and holes, it is best to get a roller with long wool of about 20 to 30 mm.

The painting
Plastic paint for exteriors, acrylic latex, coating for surfaces or a similar product that resists well to the weather, water-based. Consult the painting specialist in the store or paint shop that will advise you on the right paint. You can also use lime paints.
