Before you start with plastering, there are several things you should be aware of: Before you install fiberglass, felt or wallpaper, it is very important that you have a flat and sustainable wall. This means that all holes and unevenness must be spread out. Are there loose areas on the wall such as Loose plaster is removed and then plastered again.

You fill holes or cracks with Filler 618 or Filler Extra 619. When filling deep holes or cracks, apply ad several times until the hole is level with the surface. Make sure the filler is thoroughly dry between each putty layer. Use the putty upwards, so that the hole or crack is level and level with the wall. If plasterboard has been installed, it is also important to putty the joints. Remember to use Putty Tape 970 in the plasterboard joints and Corner Putty Tape 971 in plasterboard corners.

Putty is applied to both sides of the outward facing corner. Before assembly, the paper strip with the steel reinforcement inwards is cut and folded. The paper must not be moistened before assembly. The paper strip is now pressed firmly into the wet putty. The paper strip is now puttyed on top and the process continues as when puttingtying a normal surface.

When installing plasterboard with recessed edges, a trench is created, where there is both space for putty compound and putty tape. When putty is applied for the first time, you should be careful that the putty is pressed firmly into the crack between the plates.

The paper strip is now pressed firmly into the wet putty compound and a scraping putty is carried out on top of the paper strip. The putty must be so wide that it fills the entire recess out between the plasterboards.

The putty must now dry completely, after which a new layer of putty is applied. Depending on the requirements for the end result, a further spalling can be carried out.

If plastering is to be done in wet rooms, it is important to choose a wet room putty. Vådrumspartel 626 is stronger and more waterproof than ordinary wall putties.

In dry rooms where wide spreaders are used, our Roller Filler 627 can be recommended. This product can be applied to the wall with a paint roller and an optimal finish is achieved by smoothing with a smoothing trowel. The need for grinding is minimal. Drying time on the individual putty masses depend on layer thickness, ventilation and the surface.

Under normal circumstances, however, a drying time of 8-10 hours must be expected, before plastering can be done again. Remember to sand between each putty layer. Consumption of the putty compounds is 1m2/litre at a layer thickness of 1 mm.

After sanding the trowels, it is recommended to dust the surface to ensure adhesion of the surface treatment you then want – such as felt, fiberglass or wallpaper. This is best done with Væggrunder 224 or Væggrunder 228 Gel, which is drip-free.
