Question Of The Month - How Are Plasterboard Revised?

In dry and acoustic construction, gypsum fiber or plasterboard are used to build or clad walls and ceilings. Gypsum fibreboards are available in various standard sizes and with different edge types.

Depending on the design of the edges, whether flattened, round or semicircular, joint cover strips are used for filling. Their function is to create the non-positive connection between the individual panels. In addition, the joint-overlapping arrangement prevents the formation of cracks. In the best case, the filler to be processed is matched to the later use of the resulting surfaces. Depending on the surface - z. For example, tiles, plasters, rough or very fine wallpaper - the type of filler and spatula is selected. The requirements for filling in dry construction work are explained in detail in VOB DIN 18340, Q1 – Q4. If the gypsum fibreboard is installed correctly, there is good evenness, clean edges, joints and stability of the substructure. The above-mentioned joint deck or reinforcement strips serve as crack bridges.

Depending on the task, they are either necessary or can also be omitted. The use of reinforcement strips is also recommended when processing building boards with HRAK or HRK edging. Sufficient spatula should also be applied. A basic requirement for convincing results are clean and dust-free substrates. The various leveling compounds for use in drywall construction are each geared towards a specific application. Joint plaster of the standard category is suitable for pre-filling and grouting with reinforcement strips. The ready-to-use dispersion filler is used for subsequent filling or for full-surface processing. The processing is carried out in connection with joint cover strips, which are embedded and ensure appropriate joint strength. An attachment binder or gypsum plaster, on the other hand, is intended for attaching panels to wall surfaces.

If no cover strips are to be processed, a fiber-reinforced joint plaster must be used. The glass fibers contained ensure the necessary strength, e.g. B. when filling. Working with the so-called joint finish stands for good extensibility. The product can be used for full-surface filling as well as for subsequent filling. Machine-processed, fiber-reinforced joint filler or "joint filler" ensures particularly thin, rational processing. ZERO-LACK offers suitable Q4 products that are also insensitive to grazing light.
