General information

Gypsum plaster is primarily used for the initial alignment of the horizontal and vertical surfaces of walls and ceilings. It is applied to work surfaces to provide the last decorative finishing touch.

The ability to apply it thickly is crucial because it allows it to effectively address all imperfections and irregularities.

Plaster with a gypsum base can conceal noticeable flaws in walls, such as holes and significant damage. Gypsum plaster is used to process walls and ceilings to a high standard, enabling additional cladding, wall painting, or wallpapering.

Characteristics and place of use

The walls and ceilings of residential buildings are the main uses for gypsum plaster. Gypsum plasters are suitable for use in interior design and in locations with low relative humidity. These could be shopping malls, offices, or technical blocks.

1. Gypsum-based plaster mixes can be laid on bases:
2. Made of brick.
3. On clay walls.
4. On top of concrete walls and cement plaster, provided that the surface is treated with concrete contact.
5. You can work on old but durable gypsum plaster.
6. Cellular foam concrete, aerated concrete.

Furthermore, gypsum mixtures can serve as:

1. Starting material or ready-made solution.
2. Finishing compositions with a fine grain fraction.
3. Decorative compositions.

Composition of gypsum plaster

We can sum up by saying the following in response to the question of what makes gypsum plaster. The foundation of the entire composition is gypsum powder. It is the thread that connects each component. It is constructed from an organic mineral. In this instance, the powder is crushed and goes through a protracted heat treatment procedure. It should be mentioned that the composition may contain varying fractions of gypsum. The processing of the surface will be improved with smaller grains.

A natural or synthetic filler with fine grains is added to the mixture. The use of polymer additives is common.

The final outcome of the processed area is greatly influenced by the size and shape of the filler grains.

Fillers strengthen the working surface by consuming less gypsum plaster.

Importantly, polymers improve a material’s elasticity and adhesion to a variety of bases.

The temperature range that gypsum plaster can tolerate is +5.. +30 0 C. It is advised that the working layer be 5 mm thick, excluding the reinforcement mesh. The dry mixture is diluted one part with gypsum plaster and five parts with water. The approximate amount of material used per square meter is 8 kg.

The solution will take at least three hours to fully dry, with an average drying time of one hour. The solution reaches 100% strength in seven days. Furthermore, a mixture based on gypsum has a thermal conductivity of 0.23 W/m * C.

Kindly take note! Indices may fluctuate slightly. Everything depends on the manufacturer and the components used.

Universal gypsum plaster is available in the retail chain as a powder mixture. Paper bags with different weights are used to sell it.

Water is needed to prepare the working solution, and it can alter the composition’s fat content with certain adjustments. It all depends on what kind of work is being proposed.

For instance, rough work or cracks can be sealed with thick plaster. A liquid solution should be used for the final wall alignment on the prepared surface as well as for decorating the object. It’s crucial that it covers the wall thoroughly.

Procedure for applying gypsum plaster

Even though the product under consideration is widely used, many people are unaware of the correct way to apply gypsum plaster to a wall. However, this is a crucial query. In the end, the intended (quality) outcome won’t be obtained if the installation technology is broken.

Important nuances must be considered throughout the work process:

1. Be sure to apply the finished mixture only to a previously prepared surface, which must be cleaned of dirt, dust and pre-treated with a primer. This will give high adhesion of the working composition to the surface and increase adhesion.
2. Before applying the composition, you should determine the thickness of the working layer. If a thin layer is intended to be applied, the composition should be liquid. If you treat work areas with a thick layer, the composition should be more dense and not spread over the wall.
3. Distribution of the finished mixture on the working surface is carried out with a spatula, leveling with a rule.

Kindly take note! Plaster is first distributed and aligned horizontally in the gypsum plastering process.

The distribution of the second layer is vertical. Once the prior layers have dried, the subsequent layers can be applied. You should take a three-hour break from technology to accomplish this.

Keep in mind that the mixture’s shelf life is restricted once it is completed. Experts therefore suggest preparing a small amount of the mixture at a time.

Gypsum plastering is a common option for wall finishes because it’s adaptable, strong, and smooth. Gypsum plaster offers superior thermal and acoustic insulation in addition to helping create a perfect surface that is ready for painting or decorating. This post will discuss the advantages of gypsum plaster, how to apply it, and how to get the best results to give your walls a polished, long-lasting look.

Preparing walls for plastering

What T 0 mode should be used, and how should gypsum plaster be applied correctly? Regarding the temperature of the workspace, professionals advise priming the walls for plastering at positive indicators: 5-30 0 C. Dust and dirt are removed from the walls as part of preparation. The layers must be removed. This may be an old plaster layer or other impurities.

Kindly take note! It is imperative that metal hooks, nails, and staples be removed in order to prepare the walls. Anything that can’t be removed should be covered in an anti-corrosion material.

Brickwork, cement-lime plaster, aerated concrete, and foam concrete are examples of materials that absorb moisture readily and should be treated carefully by priming them. We also need to remember the next step, which is getting the tools and materials ready.

1. A bucket, preferably plastic, with a capacity of 10-20 liters for mixing the solution.
2. Spatulas and plastering trowels for applying the finished solution.
3. Beacons for creating a smooth surface.
4. Spatulas for setting the plaster.
5. Plaster corner for forming and leveling external corners.
6. Rule for leveling the mortar layer.
7. A trowel, which is used to level the finishing mixture.
8. Steel trowel for compaction of the applied mixture.
9. Construction mixer for mixing a portion of the solution.

Work should be done while wearing appropriate personal protective equipment and attire. Never disregard the importance of protective gloves.

Preparation of plaster mixture

One kilogram of dry matter for every 0.5–0.7 liters of water is the recommended ratio for adding dry plaster gypsum mixture into a pre-prepared container. You can determine that you will require 15–21 liters of water for a 30-kg bag of dry mixture by performing basic calculations.

Water must be added to the cement-sand mixture thoroughly to create a homogenous mass. The solution can be prepared in two different ways:

• manual method;
• mechanical option of preparation. You can use a hand-held electric drill with a nozzle, or use a professional mixer.

Note: Allow the solution to stand for five minutes rather than using a freshly made mixture. After that, the mixing process needs to be repeated.

The prepared solution should be used within 1.5 hours, as advised. The completed mixture cannot have any more ingredients added to it.

Surface alignment using beacons

Installing guides is required when using beacons to level walls. Later, the alignment happens along them. Controlling where they are in the horizontal plane is crucial. Installing beacons is advised by experts to ensure that the mixture applied is as thin as possible.

1. Firstly, this reduces material consumption.
2. Secondly, the mixture dries quickly, therefore, the work progresses quickly.

In the work, a beacon profile can be utilized. These (guide beacons) are galvanized metal slats with holes that are impervious to corrosion. The slats measure 300 millimeters in length and 6 mm in width.

Finishing without beacons

There is an alternative method of applying gypsum plaster to walls that does not require beacons. The procedure can be carried out with or without the use of a reinforcing mesh.

In essence, this technique works well for creating a decorative layer and, if required, gently leveling the surface. It’s critical to use the rules to ascertain the plane’s deviation.

You must press it to the work surface in order to accomplish this. Should any depressions exist, they need to be stretched across the work surface and lightly filled with mortar.

If there are any noticeable protrusions, they are removed with a hammer drill or ground down with a grinder, and the problematic area is then processed with a trowel or spatula following the previously mentioned procedure. Verify the rule once more to determine the plaster layer’s smoothness. You can proceed to the next area if everything is normal and there are no spaces between the tool and the wall.

Allow the plaster to set and re-harden for a while. After completing the steps outlined, the wall will be prepared for finishing. Take wallpapering, for instance.

It’s critical to notice cracks when preparing the surface. They need to be processed, puttied, and primered.
