Cover the ceiling with plasterboard

Cover the ceiling with plasterboard: cover

Plasterboard is easy to assemble and can then be easily provided with decorative surfaces: wallpaper, paint, plaster or putty cream - everything is possible. For dry interior construction, plasterboard is often used for erecting and dressing partitions or - as in our case - for covering a ceiling.

The material is available in plates of different sizes and consists of a gypsum core, which is provided with a stabilizing cardboard cover. If you work alone, you should prefer smaller formats, so-called one-man plates. For several you can also process larger formats and then progress a little faster.

We show you here as you cut the panels, screw them, fill the joints and prepare the ready-covered ceiling for further design.

Material and tools

  • Shuttering material (wooden slats or metal profiles)

  • Plasterboard, 12.5 mm thick
  • Phosphated drywall screws
  • Cordless or drywall screwdriver
  • guide rail
  • Cutter knife or carpet knife
  • edge planing
  • Possibly. telescopic support
  • Possibly. Hole Saw
  • Joint filler
  • Painter's spatula and smoothing trowel
  • Sandpaper, grain size 80 to 120
  • Wide brush or puff
  • Solvent-free substrate

Plasterboard: determine needs

First, the material requirement is determined. The amount of plates depends on the area size. Add a small excess to the calculated square footage for waste.

Join a ceiling cladding only low mechanical loads On, so you would get out here with 9.5 mm thick plates, but safe to go with 12.5 mm plates, especially since the additional costs are low.

Shading and laying direction

Plasterboard need a scaffold made of slats. If the ceiling is absolutely level, you can fix the slats directly there. However, this is rarely the case, so you attach the slats usually with adjustable direct hangers made of metal, with adjusting dowels or with intermediate balancing wedges on the ceiling.

details Information about the battens In our article, you can depend on ceiling hanging with panels and ceiling tiles.

Important: Plasterboard must not be laid with cross joints, as this would make the ceiling cladding less stable. The butt joints of the plates must therefore always have a misalignment. The easiest way to achieve this, if you the slats at a distance of half a plate length install. Then you can start the plate rows alternately with a half and a whole plate, and the impact between two plates is always on a bar. Orientate the slat profile so that this principle rises in the room with as little waste as possible and an expansion joint of 2 to 3 cm can be maintained all around.

Cut and break plasterboard

The plaster core of the plates can break very easily. This can be exploited when splitting a record - it just depends on breaking it in the right place.

Cut first with the cutter on the planned break line along the cardboard on the visible side. A long ruler or a straightedge helps. Now you can put the plate over a bar break with light pressure and then cut the cardboard on the back.

Finally, smooth the edges with the edge planer and bring along on the visible side a chamfer in the edge - that makes it easier later filling the joints.

It's best to record the cut from the front and then make it along a steel ruler or guide rail.

With the plasterboard planer, the edges are smoothed. At the same time a chamfer is cut, which later facilitates the filling of the joints.

When attaching the plates is a helper very useful, which presses the plate against the battens until it rests firmly. Alternatively, you can hold the plates in place with a telescopic support.

Now the plates are screwed to the slats. For this one uses black phosphated drywall screws, which are chemically compatible with the gypsum.In a wooden battens Use coarse-thread screws, which can be screwed in with a cordless screwdriver. At a Substructure made of metal profiles you need fine thread screws and ideally a quick-change screwdriver, which delivers higher speeds than the cordless screwdriver.

The plasterboard is screwed on all crossed slats, the push to the next plate should lie on the middle of a crossbar. The screws are screwed in so deep that slightly sunk their heads are, but not fully break the cardboard layer.

The gypsum board always bumps on a lath to the next. A telescopic support replaces the second man here.

Cover the ceiling with plasterboard: joints

With drywall screws, the plates are finally attached to the battens. Small holders (black) can provisionally fix the plasterboard until then.

Need to work Recesses for installations can be made, for example, for the management of a ceiling light, you can do that after measuring the exact position with a hole saw.

Fill in joints

After attaching all the panels is the ceiling panel not yet stable and consistently smooth. This is only achieved by filling the joints, the screw heads and minor damage. To do this, add joint filler according to instructions and press it with the painter's spatula in the joints. Then you use the smoothing trowel to cleanly remove the putty over the surrounding area.

Sometimes, the mass shrinks slightly during drying. Then it is topped in a second pass. Subsequently, the area should be as smooth as possible his. The reason: When grinding the last unevenness with 80 to 120 grit arises penetrating, fine dust - the less of it, the better. The surface has to be smooth, however, because even through a later applied paint or wallpaper you can see bumps very precisely.

The joints are filled with a trowel. All screw holes, damages or pressure points are also smoothed with the putty.

Unevenness in the putty can be smoothed after drying. Work as carefully as possible to create a perfect background for wallpaper or paint.

Edge joints and primer

The edge joints towards the adjoining walls are not filled with plaster filler - It could tear later by component movements or at changing temperatures. Here one uses a permanently elastic sealant. Important: He must be compatible with both the plasterboard and the adjacent building materials and adhere to it.

The joints to the adjacent walls are sprayed out with a permanently elastic sealant to prevent cracks at the connections.

Structurally, the plasterboard ceiling is now completed. However, before the disguise is ready for further design, it must still be primed. There are two reasons.

For one thing Plasterboard and grout each have a different absorbency. Color would absorb more quickly from the joints and have a visibly duller appearance there - the joint shape and the screw heads would later probably be clearly visible. This also applies to decorative plasters to a certain extent.

The second reason concerns mainly papered ceilings. Without primer one would Adhere wallpaper too strongly to the cardboard sheathing of the panels. In a later renovation would you then at - also much tedious - wallpaper peeling a cardboard layer in parts with tear off and would have to do before bonding the new wallpaper much unnecessary trowelling in front of him.

The Priming is not difficult and goes quickly by hand: Use a puff, a blanket brush or a broad brush to apply a solvent-free substrate to the boards and joints and let it dry. Alternatively, a wallpapering ground provided for plasterboard is suitable.

Now the blanket is really finished, and let's face it: dressing up a blanket - that was it actually not that hard or?
