Wall putty technology for plaster – how to perform correctly

Applying wall putty correctly is often the first step towards having a smooth, faultless wall finish. Filling in cracks and imperfections with wall putty produces a smooth surface ready for painting or additional decoration. The way your walls turn out in the end can be greatly improved by using putty correctly.

Although the procedure might appear simple, there are crucial steps and methods to guarantee the greatest outcomes. Every step, from wall preparation to the last sanding, is important. Applying paint correctly not only makes it look better, but it also makes it last longer.

You can apply wall putty over plaster step-by-step with the help of this guide. Whether you are a do-it-yourself enthusiast or just want to learn the fundamentals, following these instructions will help you produce results that look polished. Let’s examine the essential steps and pointers for applying wall putty successfully.

Why putty walls after plaster

Putty Plastering is one of the things that many DIY enthusiasts find most daunting. It is important to first explain the putty’s unique composition, which includes fine fractional particles that aid in sealing even the tiniest surface imperfections. Application also results in a flawless foundation that is free of defects.

Conversely, the plaster mixture is composed of large fractions that are designed to handle the sealing of large bumps; however, this results in an uneven surface because the fractions are convex rather than smooth. Because of this, painting directly over the plaster layer will cause an uneven coating that highlights flaws, and the outcome is questionable. The plaster will also be released through thin materials.

Therefore, the size of the fractions turned on is the primary distinction between putty and plaster.

Therefore, we can conclude that putty is always required on walls after plastering, with the exception of choosing a tile material for decoration or using thick wallpaper canvases to hide surface imperfections.

Among putty’s advantageous qualities, take note of:

• Helps to increase the reliability of plaster, the material will not show off over time;
• Creates a layer released by a high level of adhesion with finishing materials;
• Reduces glue consumption for wallpaper for staining surface.

Plaster’s dependability is increased by putty because it prevents the material from flaking over time.

After what time can be applied

A crucial consideration is the amount of wall to be plastered after approval. The type of plaster mixture applied to the base determines the duration.

Although complete drying takes 28 days, it can be applied after 7 days over a cement-sand layer of new material for plaster. However, he gains the required degree of setting in a week.

Depending on the composition’s brand, indicators may vary. Manufacturers typically include deadlines on packaging. Thus, it takes seven to ten days to apply plaster for facade trim based on KNAUF UNTERPUTC cement.

Playing products stand out for their quick drying ability. However, this is only for the initial setting, which takes 40–60 minutes, and the best drying condition lasts for a week. They consider that the drying time increases and can reach ten days due to humidity and low temperatures.

In other words, for internal work, the temperature and moisture indicators determine when it’s safe to putty after plaster. Another crucial factor is the application layer’s thickness. Artificial drying acceleration is not advised as this will shorten the coating’s service life. There will be an uneven evaporation of the liquid.

Products made of gypsum stand out for their ability to dry quickly, but this is just the initial setting.

Selection of putty for walls

Making the right choice for wall installation after plastering is also crucial. After all, you want a somewhat distributed putty layer on the surface and a qualitative outcome. Putty solutions of the starting type are used right after primer primer. They can be applied in a layer that is thicker than the finish.

To ensure a smooth and even coating when painting or adhering thin wallpaper, it is necessary to approach the finish type. It’s a thin layer. Putty comes in universal varieties that can be used in place of finishing or starting.

The components of the following types set them apart:

• Based on the cement, waterproof, but they give shrinkage after drying;
• Gypsum are easily distributed over the surface, but do not withstand high humidity;
• Polymeric, more expensive than the above, but the quality is higher, they do not give shrinkage, moisture resistant, to apply simply.

Both ready-made and dry mixes are available; the latter are bred with water prior to use. Although the first option is more expensive, it is more convenient.

Occasionally, the question comes up: can cement putty be applied to gypsum plaster? It is not advised to do this because gypsum reacts poorly to water, which can cause the layer to become softer. This is only allowed when gypsum putty is covered in a layer that is resistant to moisture. There are many putty mixture options available when learning how to putty cement plaster.

To ensure a smooth and even coating when painting or adhering thin wallpaper, it is necessary to approach the finish type.

Preparation of plastered walls for putty

To make subsequent actions easier, the preparatory stage is required. Plastering the walls is not sufficient to proceed to the putty stage; you must wait for the putty to dry. To improve adhesion, clear away any dust that accumulates on the surface.

In the event that the beacons were utilized, they are normally taken out and the spaces are filled with an appropriate material. But, priming the surface is still necessary after.

Do the walls need to be soil

Professionals advise applying the primitive solution for several reasons. The putty layer can be evenly distributed along the wall more easily thanks to the first layer. There is also differentiation among the following benefits:

• The gravity of the primer layer creates a film coating that prevents the formation of contaminants on the surface;
• The primer includes additives that protect the base from biological formations, moisture and others;
• A decrease in the consumption of putty and an increase in the degree of adhesion.

The primer’s gravity forms a film coating that stops impurities from growing on the surface.

Preparation of putty mixture

It is important to properly combine dry mixtures with water. The measurements are based on the packaging. Initially, a bucket is filled with water. Next, a mixture is added, and the mixture is allowed to soak for as long as the water does not draw the mixture into itself. This process takes only a few minutes.

The composition is mixed for two minutes in a construction mixer until a homogenous mass is achieved. For one minute, the composition and the solution are insisted upon.

It is not acceptable to add more mixture or water.

EXTENTION OF THE POSITION OF POSITIONS

It was previously made clear whether putty could be plastered on, but you also need to know which order to apply the putty mixture after priming and preparing. Putty can be used to remove any irregularities. The installation of a reinforcing mesh is done on large cracks.

Sandpaper should be used to remove the dried layer. After clearing the dust, the processed areas are primed once more before proceeding to the finish putty. Once more, priming and grinding are done.

Nuances of puttying angles and slopes

It is necessary to explain the idea of working with slopes and angles separately. You can grind the layer to make it equal in thickness for easier processing. The stage is challenging even for experts.

Using a pistol to apply a sealant solution that has been previously cleaned of the old composition is the second way to streamline the task. Alternatively, you can use a syringe for candy, which is hammered inside the gun, thickened with rubber linings, and adhered with electrical tape. behaves in this way:

1. A putty solution is typed in the selected tool.
2. Squeeze the putty from the syringe into the gap of the corner, it is advisable to fill out the entire void from top to bottom at a time.
3. After align the layer with an angular spatula, based on the base, how the plaster is applied to the lighthouses.
4. When the layer dries, the protruding parts are polished.

Using an angular spatula is a convenient way to act on slopes. Additionally, grinding is done. The rule verifies the evenness.

How to grind the surface

Depending on whether the mixture is starting or finish, a different kind of sandpaper is used for grinding. You can select a larger one for the first and a smaller one for the second. A grinder can be used to wipe the starter by going in a circle. It is required to shine through the surface at an angle in order to verify that there are no irregularities. If there are shadows, there is an uneven detail that needs to be polished in this location.

1 m2 consumption for plaster

The putty consumption is influenced by the layer’s thickness as well as the density of the tool’s component parts. The package may specify the appropriate consumption for each putty. However, it is possible to identify the following standard indicators per square meter:

• Cement products for the facade – 1.2-1.5 kg/ kV. m.;
• Gypsum – 0.8-1 kg/kV. m;
• Polymer – 0.6 kg/kV. m.

There isn’t a thick layer of putty. The standard is up to 3 mm for the initial putty mixture and up to 1 mm for the finish.

The putty consumption is influenced by the layer’s thickness as well as the density of the tool’s component parts.

The answer to the question in the article—whether putty can be applied to plaster—is yes. To obtain a ready-made, flat base, this step is advised. It’s critical to make the right product choice and take incremental action. The procedure is straightforward and can be completed with your hands.
