Fill the ceiling with plaster or plaster or both

Depending on the condition of the ceiling, the question of trowelling or plastering can lead to an "either-or" or "both-as". For existing holes, joints, cracks or spalling is a filling before plastering inevitable. Plaster can only seal millimeter-wide or deep cracks and holes.

Often, plaster requires previous filling

Hardly a floor ceiling has no surface injuries. Common and common are holes of lamp holders, on-site joints and slits and flaking, which are more common in rule of exception. Some roofing materials that are used for cladding or for hanging, a trowelling as the basis for the plastering condition.

The manufacturers of fillers have now developed products that make it easier to fill. Very good adhesion to the corresponding substrate material ensures relatively easy application. In most cases, troweling can be done much easier by skilled craftsmen than plastering.

Smooth surfaces give adhesion

With visually coarse decor variants, filling not only serves as the basis for the plaster. Skilled repairs of lime plaster or cement plaster often save the laborious cleaning work.

In all putty work, both level and stop layer is sought. Putty layers with thicknesses from about three millimeters provide Putz a reliable grip. In particular, such smooth surfaces as those of Rigips can only be made plasterable. Often in modern house building also additional insulation materials are used on the ceiling. The filling of styrofoam integrates this "foreign matter" and also makes it plasterable.

Save the plastering by filling

Filling is not only possible for ceiling surfaces. Typical holding functions can take care of filling, for example, when ceiling panels hit wooden supports. Again, a later plastering including the support beams can be prepared.

The different putty textures allow to produce a raster-like result without actual plaster work. When leveling at grade 2 or better, subsequent priming and painting may provide decorative appearance.

Tips & Tricks

When filling and sanding very smooth surfaces such as plasterboard, you must ensure that the filler layer remains sufficiently strong during the removal process. A two to three millimeter thick "sacrificial layer" makes work easier.
