Paint plasterboards expertly

Rigips is standard today, especially in interior design. This also increases the need for DIY enthusiasts to be familiar with all work related to the expansion of plasterboard or composite panels. A special focus here is the painting of plasterboards.

Rigips panels - the all-rounder in interior design

Rigips, or commonly referred to as plasterboard, is an important material in interior design. Non-load-bearing walls are created from this, complete wall, ceiling and floor coverings are built. Even in wet rooms such as the bathroom, the plasterboard has long been used in the form of specially impregnated plasterboard. The material is extremely easy to work with and meets many requirements with flying colors.

  • Fire protection
  • Sound insulation (in addition to the conventional drywall acoustics)
  • moisture control
  • Thermal insulation as a composite panel
  • easy to handle, nevertheless, certain
  • Strength classes can be achieved
  • individual design of interior fittings
  • Rigips panels can be wallpapered, tiled, plastered or painted
  • very inexpensive

The leveled and sanded plasterboard surface is determined in quality grades

Depending on how the drywall construction is to be further processed afterwards, there are a total of four quality grades from Q1 to Q4. These quality levels define the quality of the putty and grinding work. To paint plasterboard you need at least the quality level Q3. Quality level Q4 must be achieved if you want to varnish plasterboard or cover it with filigree metal wallpaper.

Make sure that the plasterboard has at least grade Q3 for painting

The preparation of the plasterboard is therefore elementary. Therefore, you must ensure the level of putty and grinding before painting the plates in any case. What you can feel with your fingers on a seemingly neatly leveled and sanded plaster board on bumps, can be clearly seen after painting. Even more dramatic even with painted plasterboards.

You can perform another quality test with light. Place a halogen spotlight on the plasterboard and light up along the plates. Emerging big shadows speak for quality defects. However, slight light shadows may still be discernible in quality level Q4, since the perfect finish is almost impossible - even for experienced craftsmen.

Choosing the right color: it must be compatible with plaster

As the name implies, an important part of the plasterboard is plaster, and also in the filler. Gypsum is a very absorbent material. It even attracts water. However, the plaster also gives off moisture to a very dry environment and thus regulates the room climate. This property is quite intentional. However, certain color systems act like an enveloping and closed seal.

It can no longer be penetrated by moisture (not permeable). These include, for example, emulsion paints. Accordingly, you should weigh the use of emulsion paint well. In addition, gypsum is not compatible with any color system. These in turn include pure silicate paints. These start an undesired chemical process on gypsum, which leads to surface tensions and thus to cracks.

The optimal choice for painting plasterboard: dispersion silicate paint and the corresponding deep primer

Dispersion silicate paint, which has nothing to do with emulsion paint and nothing with silicate paint, however, is best suited. Dispersion silicate paints are permeable, so that the plaster can take over its moisture-regulating task. However, to apply dispersion silicate paint, you need a special depth primer. This regulates the suction behavior of the plaster and ensures optimum setting of the wall paint. As a result, you first need to work on plasterboards with a deep background. Then you can then paint the dispersion silicate paint on the plasterboard. It will probably be necessary to apply the wall paint in two steps.

Tips & Tricks

If possible, use a neutral color primer. If you only get colored primers, try to buy them in similar but brighter colors than the later wall paint so that the primer does not show through later.

If you want to use centuries-old and appropriately tested systems, you can also use lime or lime mud paint. This paint, made of slaked lime, is also vapor-permeable and above all has a luminosity that is not achieved by any modern color system. However, lime color darkens.

The primer on the plasterboard has another task: it ensures that certain substances that turn the plates yellow, can not escape from the plates.

If you have the plasterboards assembled by a specialist company, you can also agree a corresponding quality level in the contract for the handover. Painting work carried out by painters must be carried out including priming. Everything else is not allowed.

Rigips is actually a brand name like the similar naturalized "Flex" (brand name for an angle grinder) or the Widia drill (brand name for a sintered drill).
