Correctly paint a plasterboard ceiling

Rigips is a tried and tested material for interior construction and is therefore often used. That is why the use of plasterboard is more and more important for the experienced do-it-yourselfer. A classic finishing process for a plasterboard ceiling is painting. In the following we explain to you what you have to pay particular attention to when painting a plasterboard ceiling.

Rigips ceilings must be prepared according to the desired quality level

Plasterboard panels have long replaced classic, brick partition walls and plastered ceilings. Rigips has heat and sound insulation properties, is extremely quick and easy to apply and almost any type of surface can be applied: tiles, plaster, wallpaper, wall paint and much more. However, a plasterboard ceiling must be prepared with varying degrees of intensity depending on the desired surface finish. It is about how high-quality a plasterboard ceiling is filled and sanded.

To paint or varnish a plasterboard ceiling, you need at least Q3 or even Q4

In the lowest quality level Q1, joints and screw holes are roughly filled and sanded. This means that the subsurface is sufficiently prepared for tile laying. A plasterboard ceiling can be painted in the highest quality levels Q3 and Q4. While Q3 is sufficient for conventional wall paint, Q4 is absolutely necessary if a wall or ceiling is to be painted. The texture of the surface can be compared with a mirror-smooth fine plaster layer.

The plasterboard ceiling must be of the quality required for painting, even if it looks good at first glance

In the high quality levels, the presence and intensity of light shadows are checked, which can be seen very quickly on uneven surfaces. Before you paint your plasterboard ceiling, you should definitely check whether there are too many shadows with a halogen spotlight that you hold up to the ceiling and then shine along the ceiling. You can also feel the ceiling with your fingers. Basically, the rule of thumb here is: every unevenness that you perceive with your hands can later be seen extremely well on the painted plasterboard ceiling. There are no compromises here, especially with varnished plasterboard ceilings.

Which is why you should use very special color systems for painting plasterboard ceilings

The rigipplatties as well as the rig pipe contain gypsum. Gypsum is an exceptionally strongly absorbent background. So the absorbency of the ceiling must have the later wall paint or. be adapted to the paint. The specialist retailers offers a special depth basis (€ 4.81 at Amazon *), which you can delete on the rigip ceiling. Then you have to dry the depth primer according to the manufacturer's instructions accordingly. Under no circumstances may the primer of many manufacturers be completely dehydrated, otherwise they are not with the later painted wall paint resp. Bind the paint. Also make sure that the depth is tolerated with the wall color used, ie, for example, dispersion silicate color.

Rigips acts moisture regulating, which should also correspond to the color used

In addition, not every wall paint is equally suitable for rigip plates. Silicate paints, for example, have excellent properties on mineral substrates such as lime, but not on gypsum. The silicate paint cannot silicify; on the contrary, undesirable chemical reactions occur, which cause tension in the coating and lead to cracks. As already mentioned, plaster of paris is highly absorbent. These attributes have a dominant influence on the room climate. Because the plaster of paris can not only absorb a lot of moisture, but also releases it again according to the external influences. These excellent regulating properties are another reason why Rigips is so popular.

You can use these colors to paint the plasterboard ceiling

On the other hand, there is now the wall paint that is primarily used, namely emulsion paint. This acts like a seal and seals the plasterboard ceiling. As a result, no more moisture can be exchanged. Accordingly, you should avoid emulsion paints when painting a plasterboard ceiling. On the other hand, emulsion silicate paint or silicate emulsion paint is best suited.

This wall paint has nothing in common with emulsion paints or with silicate paints. Another very suitable color for plasterboard ceilings is lime paint (€ 14.49 on Amazon *) . Lime sludge or lime paint was the paint in general for centuries. Compared to modern color systems, there is even the advantage that lime paints have significantly more luminosity. In return, however, they darken over the years. Lime paints can be painted over at any time and without problems and, like dispersion silicate paints, are also open to diffusion, so that the Rigips can regulate the room climate.

Painting the plasterboard ceiling

If you now have the right depth base that is compatible with the selected color system, you still need suitable tools. Which rollers you want to use depends heavily on the surface structure of the color coating you want to achieve. Painters prefer to use foam rollers, as they can be used to achieve a finer grain size. Of course, you can also paint test areas yourself and try long-haired lamb pile rolls. Otherwise, painting a plasterboard ceiling with the appropriate materials and tools does not differ from the painting techniques for conventionally plastered ceilings. Just keep in mind that you will need extension poles for the paint rollers and an easel. In addition, as with other paint systems, you have to mask off with masking tape on corners and edges.

Tips & Tricks The priming of the plasterboard ceiling fulfills another task: the deep primer protects plasterboard surfaces painted in this way from the otherwise frequent yellowing. In particular, plasterboard surfaces that are increasingly exposed to UV radiation tend to yellow quickly.

If you have the interior work carried out by a drywall construction company before moving in, you also agree on the respective quality level of the plasterboard ceilings and walls in the contract. This is then binding for the company. If you also want to have plasterboard ceilings and walls painted by a specialist company, check the mandatory use of a deep primer. Otherwise, hairline cracks will appear very quickly, especially on the filled surfaces.

Taking into account the moisture regulation of Rigips is particularly important in new buildings. For example, tightly closing windows caused the mold that has not existed for centuries. It is only in the last few years that many people have come to understand the interrelationships between the individual components and their properties in the interplay of the entire house climate. The ability of plasterboard ceilings and walls to diffuse is a cog in the entire process of sustainable building and living.
