Painting a façade professionally

More and more homeowners are taking over the painting of walls and ceilings and the painting of their facades. However, the painting of a house facade differs significantly from the painters in the interior of the house. In order to make your facade painting professional, you will then receive detailed instructions for painting a façade.

Note the special features of a facade before painting

Home improvement has long been taking on even the most demanding jobs, such as the painting of a façade. But as well as the walls in the interior of the house and the color systems used have their peculiarities, it also behaves with facades and the associated façade colors.

Check the façade thoroughly

Especially important is the inspection of the facade and its immediate properties. To narrow these properties, you need to do several tests

  • wicking
  • scratch test
  • hammer test
  • wipe test
  • visual inspection

The suction test

With the suction test, you can determine how much or less the plaster of your façade sucks up liquid. For strongly absorbent facades, you may need to apply a primer as a primer, which reduces the absorbency to a normal level and for optimal setting of the facade color. It is best to apply water with a sponge. You then see the discoloration or that the water bubbles off, how absorbent the facade is.

The scratch test

The scratch test provides information about the consistency of the plaster. Scrape it medium with an old screwdriver on the plaster. Perform this test in different places and at different heights. If the plaster dissolves strongly, it must be partially removed in the worst case. You may also be able to work the façade with a suitable primer.

The hammer test

Tap the hammer with a hammer and place it on the facade. If the plaster begins to crumble underneath, you must either expose affected areas generously and compensate with repair mortar or the entire facade plaster must be renewed.

The wipe test

The wipe test will tell you if the facade is chalking. Wipe with the palm of your hand over the facade. If this is now very white or dusty, the facade chalks strongly. Among other things, this may indicate the use of lime paint. If you use modern facade paints such as emulsion paints, you must first remove the lime paint.

The visual inspection of the facade

Finally comes the visual inspection, which you can usually perform in parallel to the other tests. If the facade is heavily soiled, it must be cleaned accordingly. You can use water and a brush, but also a high-pressure cleaner. Algae, lichens and mosses must be completely removed.

At the same time, check the façade for crumbled plaster or cracks. You can fix both with repair plaster up to a certain size. Before you start brushing after cleaning the facade, it must be completely dry. Take into account that the water can penetrate relatively deep into the plaster and takes time to dry.

Step-by-step instructions for painting the facade

  • exterior paint
  • possibly primer
  • duct tape
  • cover
  • possibly repair plaster or mortar
  • framework
  • high pressure cleaner
  • Paint roller with telescopic poles
  • brush
  • Tool for the different tests

1. Preparatory work

After completing the inspection and repair of the facade, you must start to cover before painting. Cover even the windows and doors with foil and glue them accurately to the respective finishes. The same applies under the eaves and at basement windows or paths around the house.

2. Priming or priming the facade

Apply the primer following the manufacturer's instructions. You can dilute a primer with the later facade paint with 10 to 15 percent water.

3. Painting the facade

First, stroke edges, corners and angles that you can not reach with the paint roller. Brush it generously into the free areas. Do not paint all the edges at once, just so many that you can still paint the surrounding area with the paint roller, as long as this color is not dry yet. This "wet in wet" coating will help you avoid staining later.

In the process, paint the façade in the cloister. This means that you first swipe from left to right and back and then up and down or vice versa. This ensures that the facade paint is blended and a uniform color is applied. This will help you avoid unsightly stains.

Tips & Tricks

Paint your façade at the right time of the year. In winter it is too cold for the paint to dry. In midsummer, however, it can be too hot, so that the color dries too fast. This is especially true if you paint in the blazing sun.

Pay special attention to the weather side. Do not talk about any damage by "it will work" by yourself. The painting of the facade is complex and costs money. If you do not prepare the façade properly and eliminate old damage, it will be visible again within a very short time.

In addition to the painting of the façade, there are numerous other articles in the house journal about this work around the house. This includes the coating of roofing.
