Exterior wall painting
Painting the exterior walls of our house is an crucial investment for our property. This comes from the fact that it is a very important and technical work for its renewal and maintenance, a work that must be done every 5 to 10 years. By painting the exterior of our house, the property acquires the right aesthetics.
Also a high level of protection from the sunshine and humidity that harms it, but also durability over the periods. Especially in countries where most days of the year there is sunshine, the procedure of painting the exterior walls of a building or an apartment is necessary and imperative.
That way we can maintain the outer of the building in order to look beautiful and be in an excellent condition. Exterior painting has to do with all the exterior surfaces of our home or workplace. By this way we mean the plastered or the concrete facades of the property, our balcony ceilings, the wooden or metal protective railings.
Also the exterior wooden or metal doors, wooden pergolas and the outer guardrails. Every exterior surface needs the right application and the appropriate products, if we want to achieve the ideal result that is going to aim the triptych: aesthetic superiority, ideal finish and duration in time.
The work of painting exterior walls
In order to have an excellent quality exterior painting, the key is the good cleaning of every surface that is gonna be painted, so we can apply the paint on a clean wall. There are four key pointers in moving your paint around:
1. check the plaster for it’s hollow
2. carefully check for any signs of moisture into the plaster
3. checking the wall forinflated colors
4. cleaning and properly prepare our surface to pass the first substrate, using the suitable material, emaning the primer.
Before you apply the paint, you should scrape and remove the hollow plasters and peels of older paints, to completely clean the wall.
If there is any deep corrosion on the surface, there is a chance that the removal of the loose materials may expose the bricks or iron bars. In a case like this, the damage is repaired and new plastering should be done, before we proceed to the procedure of oil painting.
If there is no deep corrosion, but only simple cracks and shallow holes, then we should plaster the spots when the damage is. This action is followed by the one of rubbing with a sander, just in order to remove the residues from the stucco, until the moment we will have a wall that is clean and also free of dust or dirt.
After the process of cleaning and when all the surfaces are completely dry, then we apply the primer. This helps facilitates the application and ensures us a uniform surface in the final color. The substrate will bind with the paint and seal our final painting.
After priming, our walls is ready to accept the color of our choice. Remember that the choices of the materials also play an important role. We suggest you choose paints of good quality, that will ensure good adhesion and penetration with high elasticity and resistance to alkaline surfaces, achieving a very good bond with the substrate.
For the exterior walls, we suggest you to choose the silicone acrylic paint, the one that protects from moisture. However, depending always of your needs there are plenty other options .
Use of quality materials in exterior painting
Always remember that exterior paints are completely different from the paints we use for the interiors. Also, each material on the facade or the exterior walls needs a different type of paint.
In the case we want to paint over materials like wood, aluminum, or plastic and plaster, these building elements is having their own type of painting and their own materials for this action.
There are a big number of paints on the market especially for exterior walls, ones that protect them as they are not affected by the environment conditions, the temperature changes, the air pollutants and the sunlight.
An economical solution could be the acrylic water-based paint for outdoor use, that is is suitable for surfaces that we paint frequently. It can be applied to exterior walls, to cement boards and plaster. Even on cement surfaces, concrete ones and generally in places where the surfaces are alkaline .
In case that you want something more, especially the ones that the property is located in an area with humidity, emaning near the sea or into the green, you can use a silicone acrylic paint in the cost of an extra charge.
Silicone acrylic paints are always recommended for exterior walls, as this type of paint can prevent the accumulation of dust and dirt on our surface and allows the rain to wash them away, managing to keep the surface clean for quite a long time.
Additionally, the silicone acrylic paints will offer you excellent waterproofing. Due to the high water repellency they have, the penetration of the external moisture and also rainwater into the wall will be prevented. That’s something offering you a long-term protection of the surface.
Also it allows the moisture that is trapped inside the surface of the walls to escape with great ease into the atmosphere. In this way we protect them against bloating and also peeling and molding.
The silicone acrylic paint will offer you an excellent performance and also ease of application, while giving you a uniform matte finish of high perspiration.
Exterior wall painting and weather
If we want to paint outdoor, the ideal weather conditions for this procedure are during a day with a relative cloudiness. One with moderate temperatures and also normal humidity conditions.
The right weather conditions can ensure us that the paint will dry properly and an end result that will be durable over periods. The calculation of the amount of color that we are going to need is approximate.
It is based on the performance of the product that we selected per liter and per square meter. Remember that the calculation of each product concerns an application. Usually the substrates need one coat of application, but the final paints need two coats.
We believe to have helped you with your outer walls painting. At first it may seem difficult but after a while you will see that it is something not to worry about.
