Expertly paint a plasterboard ceiling

Rigips is a proven material for interior design and is used accordingly often. Therefore, dealing with rigs for the savvy home improvement is always important. A classic finishing of a plasterboard ceiling is the painting. Below we explain to you what to pay attention to when painting a plasterboard ceiling.

Rigips ceilings must be prepared according to the desired quality level

For a long time gypsum plasterboards have replaced classic masonry partition walls and plastered ceilings. Rigips has heat and sound insulating properties, is exceptionally fast and easy to apply, and can be applied to virtually any floor covering: tile, plaster, wallpaper, wall paint and more. However, a plasterboard ceiling must be prepared with varying intensity according to the desired surface finish. It's about how high quality a plasterboard is filled and sanded.

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

In the lowest quality grade Q1 joints and screw holes are coarsely grouted and ground. Thus, the substrate is sufficiently prepared for tiling. In the highest quality grades Q3 and Q4 a Rigipsdecke can be deleted. While Q3 is sufficient for traditional wall paint, Q4 is required when painting a wall or ceiling. The surface is to be compared in nature with a mirror-smooth fine plaster layer.

The Rigipsdecke must necessarily the required quality for painting accordingly, even if it looks good at first glance

In the high quality grades, the presence and intensity of light shadows are examined, which can be recognized very quickly on uneven surfaces. So before you paint your Rigipsdecke, you should necessarily with a halogen spotlight, which you hold to the ceiling, and then to shine along the ceiling, check if there are too many shadows. You can also feel the blanket with your fingers. Basically, here is a rule of thumb: any unevenness that you perceive on the hands, is later on the painted Rigipsdecke very good to see. Especially with painted plasterboard ceilings there are no compromises.

Why you should use very special paint systems for plasterboard painting

The plasterboard as well as the Rigip filler contain gypsum. Gypsum is an exceptionally absorbent substrate. So the absorbency of the ceiling must be adapted to the later wall color or the paint. The specialized trade offers a special depth reason, which you can put on the Rigipsdecke. Then you have to let the deep primer dry according to the manufacturer's instructions. Under no circumstances should the primer of many manufacturers dry out completely, as otherwise they can not set with the later painted wall paint or varnish. Also make sure that the depth base is compatible with the wall paint used, for example, dispersion silicate paint.

Rigips has a moisture-regulating effect, which should match the color used

In addition, not every wall color is equally suitable for plasterboards. Silicate paints, for example, have excellent properties on mineral substrates such as lime, but not on gypsum. The silicate paint can not be silicified, on the contrary, there are unwanted chemical reactions that cause stresses in the coating and lead to cracks. As already mentioned, gypsum is very absorbent. These attributes dominate the indoor climate. Because the gypsum can not only absorb a lot of moisture, but also releases it according to the external influences. These excellent regulation properties are another reason why Rigips is so popular.

You can use these colors to paint the plasterboard ceiling

This is contrasted by the primarily used wall paint, namely emulsion paint. The acts like a seal and closes the Rigipsdecke. Consequently, no moisture exchange can take place. Accordingly, you should also dispense with dispersion paints when painting a Rigipsdecke. On the other hand, most suitable is dispersion silicate or silicate dispersion.

This wall paint has no similarities with either dispersion or silicate paints. A likewise very suitable color for Rigipsdecken is lime paint. Lime mud or lime paint was the paint for centuries at all. Compared to modern color systems, there is even the advantage that lime colors have significantly more luminosity. But they darken over the years but after. Lime colors can be painted over at any time and without problems and, like dispersion silicate paints, are also open to diffusion, so that the plasterboard can regulate the room climate.

The painting of the Rigipsdecke

If you now have the right depth, which is compatible with the chosen color system, you still need suitable tools. Which roles you want to use depends very much on which surface structure of the color coating you want to achieve. Painters prefer to use foam rollers because they allow a finer grain size to be achieved. Of course, you can also paint test areas yourself and try long-haired lamb fillet rolls. Otherwise, the painting of a plasterboard ceiling with the corresponding materials and tools does not differ from the painting techniques of conventionally plastered ceilings. Just keep in mind that you need paint roller extension rods and an easel. In addition, tapes must be taped to corners and edges as with other paint systems.

Tips & Tricks

The primer of the Rigipsdecke fulfills a further task: the Tiefengrund preserves thus painted Rigipsflächen before an otherwise frequently occurring yellowing. In particular, plaster surfaces that are exposed to increased UV radiation tend to rapidly yellow.

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

The consideration of moisture regulation of Rigips is especially important in new buildings. With, for example, tight-fitting windows came the mold, which did not exist for centuries. Only in recent years, many people increasingly understand the relationships between the individual components and their properties in the interaction of the entire home environment. The diffusibility of plasterboard ceilings and walls is a cog in the entire transmission of sustainable building and living.
