The joint tape at Rigips


When filling drywall panels, a so-called joint tape is often used for the joints. On the other hand there are craft businesses that advise against a joint tape and certain conditions. When to use a joint tape with Rigips and when not, you can refer to the following guide.

Plasterboard or plasterboard

First a short reference to "Rigips". Rigips panels are plasterboard or GK panels. Specifically, it is the brand name for plasterboard manufacturer Saint Gobain. Since this manufacturer was already on the market, as this form of drywall became more and more prevalent and market leader, the brand name Rigips became synonymous with the term gypsum board or GK board. So when we write about Rigips below, it means gypsum plasterboard in general terms.

The processing of plasterboard or plasterboard

Rigips panels can be used differently on walls:

  • screwed to the framework as an independent partition
  • glued to an existing wall

The joint tape at Rigips: joint tape

The joints of the Rigips panels are filled. For this purpose, a joint tape is often used. This is basically a reinforcing tape, which is to make the grouted joint more resistant, for example, against cracks.

Fill plasterboard with or without joint tape?

Now, however, it is becoming more and more common to hear that the connection joints of Rigips could be filled even without a joint tape. Many DIY enthusiasts are therefore unsure. Basically, that's right. Previously, a filler was used to fill the Rigips joints. Today, on the other hand, usually two different fillers are used for pre-filling and post-filling.

In addition, the leveling compounds, like flex tile adhesives, can be specially tempered and then more flexible. In other words: these fillers do not tear so easily, if it should come to tensions or mechanical pressure. And so we would be at the point when a joint tape for Rigips is recommended and when you can do without it.

If cracks are likely, use a joint tape for the Rigips panels

So it has something to do with the likelihood of cracks along the joints. Stress cracks, for example, occur at butt joints when two different materials collide at the same time, as they also have a different thermal expansion. So, for example, when connecting joints to other materials you should use a joint tape.

Dry wallboard glued to an existing wall hardly moves at all, unlike a dry wallboard attached to a stud. However, as it becomes a complete drywall, the more unstable it becomes. Especially if it can not be screwed to the floor and can only be attached to the side connecting walls.

Are you unsure, better always use a joint tape

Basically, therefore, a pure drywall is "less stable" than glued plasterboard on a wall. By design, this instability can be greater. Therefore, it makes sense here to use a joint tape.

From which size and type of installation, can not say flat rate. Rather, you should not do without a joint tape, if you are not sure that the grouted joint could not tear later. On the other hand, in the case of glued plasterboard you can do without a joint tape in most cases.
