Putz? What does it mean?

The term “plaster” refers to a covering which consists of mortar and different binders. The plaster mortar allows the application of wallpaper to the re-smooth surface. It also protects the interior walls and contributes to better moisture regulation in every interior. To start the plaster you need a trowel made of stainless steel, a smoothing trowel for putting on the plaster, a grape box, small trowels (for example cat’s tongue) for editing the areas around windows and door frames, as well as a float. To felt the plaster surface during the setting process, you also need a sponge board. Our tip for the perfect mixture of the plaster: To help the electric agitator comes, so that the plaster is touched correctly! When mixing a mortar is particularly well suited.

The agony of choice!

But which plaster should you use? Which type of plaster is used depends in principle on the substrate. Since plaster is not the same plaster! With regard to the binder added, some types of plaster differ. Since the binder consists of gypsum, lime, cement, loam or only one combination, the following plaster types are available:

  • Clay and clay gypsum plaster: This type of plaster regulate the humidity and are considered as heat storage. However, as they swell with moisture, they are best suited for internal use.
  • Gypsum plaster: Gypsum plaster may only be used indoors. Because of its versatility, it serves as the basis for wallpaper, paintings or even tiles.
  • Cement plaster: Namely the cement plaster is the best choice for surfaces with too high moisture load.

Plaster walls – Which plaster?

The right tools!

Step 1: Prepare walls properly!

First remove dirt and loose particles from the wall! To properly plaster the wall, it should be completely dry and clean. Attention: If you plaster an old building wall, the substrate should be well wetted. So the plaster keeps better! For this you need a ceiling brush or a painter’s quast.

Mask built-in parts such as windows, cabinets, doors and the floor to protect them! Cover as desired with a foil!

Remove old plaster! Tap him with a hammer and a chisel!

Brush off the dried wall! Smooth holes with putty!

Step 2: Set corner foil out of sheet metal!

Apply plaster grout in small quantities at the edges! Press metal sheet with a straightedge! Let the plaster dry for at least one hour!

Step 3: Put plaster strips!

The so-called cleaning strips (also: plaster profiles, plaster slats or plaster rails) ensure that the plaster surface is as flat as possible! Fix plaster profiles to the walls with mortar! Attention: Cleaning strips must be exactly vertical with a distance of 1 and 1.5 m.

Step 4: Pre-wet the wall with water and prime!

For this you need a painter’s quiche! Pre-wetting prevents the wall from absorbing the water content of the plaster early on.

For substrates such as concrete or drywall, the primer is a must. It should be applied using a roller or puff.

Then let it dry out!

Step 5: Mix the plaster!

Mix plaster with clear, clean water in a bucket! An agitator for the drill ensures easier stirring. Let plaster to mature!

Step 6: Apply plaster layers – Apply under- and top coat!

The flush serves as the basis for the second layer of plaster. Take the plaster with the trowel and carefully throw it on the wall! Then let it dry! After drying the first coat, apply the top coat directly with the smoothing trowel! Make sure that the thickness does not exceed 10 mm!

In this way plaster the whole wall!

Step 7: Smooth the plaster!

Finally, smooth the wall with a pull-down board or with a grape-cane!

You only have to plaster walls for experienced DIYers!

If you follow these tips and follow all 7 steps correctly, you are looking forward to a nice, smooth wall. We wish you lots of fun plastering walls!
