Plaster or putty?

Their primary distinction is grain size. Less roughness results from a thinner minimum layer applied and a binder with smaller grain size. The most common universal plaster, KNAUF Rotband, for instance, shows a fraction size of 1.2 mm. Naturally, though, the gypsum particles are actually smaller. All they are done is sift less carefully than in putty. Consequently, the solution has grains that are visible after mixing with water. The texture of putty is similar to sour cream.

For putty KNAUF Rotband Finish, the recommended thickness of the applied plaster layer is 0.2–5 mm, while the manufacturer Knauf recommends 5–50 mm.

Use plaster if you need to level big holes and depressions. Once it has dried, smooth it with the finest grater or fill it with putty. For covering up drywall joints, putty works well right away.

Now let’s return to processing the plasterboard joints.

Necessary materials and tools

1. A container for mixing the dry mixture;
2. primer, for example, polymer Knauf Tiefengrund;
3. narrow and wide spatula;
4. Painting net;
5. construction knife;
6. grater;
7. brush;
8. dry mix or paste in a bucket.

How to plaster gypsum board correctly

1. Before plastering with a knife, cut the edges of the drywall at an angle of 45°. At the junction of the sheets, an angle of 90° is obtained. By the way, small planes are sold especially for chamfering, they are used even before fixing the gypsum board to the wall.
2. Dust is shaken off with a brush or a brush.
3. The cut chamfer is primed so that moisture from the putty does not go into the gypsum, and the seam does not crack.
4. Putty is mixed in a tray or bucket. Ordinary cold tap water will do for this. If there is no time to calculate the proportions recommended by the manufacturer, then you can correctly select the consistency of the mixture as follows. Fill half the container with water, use a small scoop or use your own hands to take the putty from the bag and spread it evenly! pour water over the entire surface. Pour until the putty goes under water. As soon as the water stops hiding the powder, you can start mixing. It is better to do this manually using a small spatula.
5. Next, the plasterboard seam needs to be filled with putty and leveled along the entire length. It is more convenient to apply with a narrow spatula.
6. A reinforcing mesh is applied to the fresh solution and lightly pressed. Then it is covered along the entire length and width with a new layer of putty. Use a wide spatula for leveling.

Crucial! It is important to monitor the prepared solution’s viability and drying time. The binder affects these indicators. For instance, the layer of mixed gypsum putty KNAUF Uniflot on the wall dries completely after an hour and hardens after thirty minutes. Additionally, the WEBER-VETONIT polymer mixture with marble filler permits the solution to function for a duration of 24 to 48 hours; however, the layer will require 24 hours to dry out.

Working with gypsum board on the wall and plastering the ceiling are essentially the same. The same equipment and supplies are utilized. The intersection of the wall and ceiling needs special consideration.

Decorative plaster: types and features

Let us now address the problem of plasterboard walls in the strict sense of the word, meaning covering the entire surface with an exquisite decorative layer.

• Venetian. Its main feature is a combination of several colors and a glossy surface, often imitating marble.

Buckets of pre-made compositions are available. However, you can also create a Venetian mixture by hand using universal gypsum and coloring it.

Typically, multiple layers are applied, with the first one being simply white. It produces tiny irregularities and texture. The texture is emphasized by the second layer, which is colored. The third one brightens certain areas or adds color.

A light rub of the dried mixture would be a good method. The lower white layer will emerge after the tops of the texture protrusions are removed. At the very end, protective wax is applied to give the Venetian its gloss.

• Textured (relief). This name is conditional, because any plaster with a beautifully created textured pattern can be attributed here. But there are also established types, such as "bark beetle", imitating wood eaten by insects. The pattern can be very diverse, abstract or geometric, repetitive or chaotic. It all depends on the imagination of the master. To create the texture, use a spatula, trowel, coarse brush, sponge, special rollers and stamps, etc.

• Plaster with filler. This type includes marble plaster with crumbs of natural material, various flocks (chips) in the form of thin plates, pebble plaster with a “fur coat” effect, and others. As a rule, they are sold ready-made, sometimes additionally tinted to the desired color. Applied in an even layer and left until completely dry.

• Liquid wallpaper. This type of decorative finish has a cellulose base with the addition of fillers – silk, cotton, acrylic binders, dyes and other additives. Sold in bags like dry plaster, soaked in water before applying to the wall. Walls under the wallpaper are primed. The finished mixture is applied to the drywall and leveled with a spatula.

Plastering technology

After priming, drywall should be covered with decorative plaster. It will require two primes from you.

First, a high penetration primer, such as Ceresit CT 17, is applied to the gypsum board. It will lessen the drywall’s susceptibility to moisture. applied in a single layer using a brush or roller, then allowed to dry completely.

To improve the adherence of the decorative coating and base, prime twice. Because Ceresit CT 16 contains fine quartz sand, which adds roughness, it is appropriate for this use.

Apply a decorative layer after the primer has dried.

With a trowel, you can create an abstract pattern. Using a spatula, apply a small amount of solution to it. Then, use a trowel to spread the mixture over the wall to create texture.

Decorative plaster can be applied to drywall with a large spatula and leveled straight from the ceiling to the floor when using relief rollers to create a pattern. A roller is used to create a textured pattern on the wall after a few minutes, when the ornamental layer starts to solidify. Instead of using a roller, you can use different stamps and prints.

Applying and leveling liquid wallpaper and mosaic plaster on a wall is an easy process.

The surface is covered with protective wax if needed.

When you use the right tools and follow the right procedures, plastering drywall is a simple process. A smooth, polished finish can be attained by properly prepping the surface, selecting the right kind of plaster, and applying it uniformly. Keep in mind to apply the plaster in thin layers and to wait until each layer is completely dry before applying the next. This guarantees a long-lasting surface and helps prevent cracks.

With the help of the given instructions and video tutorial, you can observe directly how to use various plastering methods and instruments. The plastering process is made simpler to comprehend and carry out with the help of the video tutorials, which provide visual demonstrations in addition to written instructions.

Plastering drywall can be a rewarding do-it-yourself project if you have the patience and attention to detail. By adhering to these recommendations, you can attain an impeccable finish that will improve the look and longevity of your walls.
