Characterization of a cement-lime solution for wall plastering

The quality of plastering is an important factor in maintaining and beautifying a house’s exterior. The cement-lime solution is one of the materials that is frequently used for wall plastering. This blend of cement, lime, and occasionally sand gives external walls a long-lasting and attractive finish. Because of the strength and flexibility provided by its composition, it can be used in a variety of environments.

Compared to other plaster types, a cement-lime solution has a number of advantages. It provides a smooth and uniform texture by adhering well to a variety of surfaces, such as stone, concrete, and brick. This kind of plaster is renowned for its breathability, which lets moisture escape the walls instead of keeping it there. This attribute contributes to the longevity of the building’s facade by keeping moisture and mold growth at bay.

Moreover, skill and attention to detail are needed when applying cement-lime plaster. A smooth surface is necessary to guarantee uniformity and adhesion. For the mixture to form a solid bond and a long-lasting finish, it must be applied evenly and given enough time to cure. To obtain the desired aesthetic effect, extra layers or a final smoothing may be required, depending on the desired texture.

Types of cement mixtures

A wide range of pre-made building mixtures are available in the construction markets. However, mixtures, including cement, are used more frequently. Developers add certain components to the compounds to enhance the properties. The mixture’s primary types are:

• Sandy.
• Lime.

Cement is the constant element in these kinds.

Cement-sand mortar

This composition is often used in damp rooms. The cement of brands between mm 150 and mm 500 is the primary component solution. A brand with a small indicator is used for internal work, and one with a large indicator is used for external work.

An additional part of the solution is sand. Element ratios of 1: 3 or 1: 4 parts sand are advised. Buying mixes with medium-grained sand is preferable for alignments with thick layers. After drying, this mixture won’t crack, and compounds containing fine fractional sand are utilized for finished projects. Fit for working on the streets.

Manufacturers add a variety of additives to their solutions to enhance their quality. You can achieve enhanced strength, elasticity, frost and moisture resistance with this composition combination.

Cement-ledge plaster

This is a mixture that is used in repairs. Compared to sandstone, working with cement-lime plaster is simpler. It is vapor permeable, has more plastic, and lies more smoothly on the surface. However, its strength is not as great as that of sandstone.

This solution is made up of cement, polyoximethylin, quartz sand, gash-lime, and polypropylene fiber. This composition resists the growth of mold and fungus well. made in separated and powdered form. This method is only applied to building cladding or internal work. Assemble a collapse for management-only work to prevent the composition’s qualities from degrading.

Positive characteristics

• Used for all known wall surfaces.
• It grows well with the surface when applying.
• It has antibactericidal properties.
• The solution does not set for a long time after breeding, which allows long -term work.
• Supports the humidity level in the room.
• The surface treated with the solution has a long service life.

Anyone interested in maintaining or remodeling the exterior of their home must understand the cement-lime solution used in wall plastering. This post explores the useful features of this adaptable plaster mixture, outlining its ingredients, usage guidelines, and advantages. Cement-lime plaster gives homeowners a dependable way to preserve and adorn external surfaces, while also improving durability and imparting a smooth finish. This guide seeks to equip readers with the knowledge necessary to make educated decisions regarding the maintenance of their home’s facade by examining its features and recommended practices for application.

Characteristics of cement-license solution

Nearly all dry cement plasters share the following technical traits:

• Dry mixture has a gray color.
• Compression strength – 6–12 MPa.
• The gear adhesion is 0.3–0.4 MPa.
• Cement brand – mm 100 -mm 500.
• Allowed thickness, application at a time – 5-4 cm.
• The consumption of the composition per 1 kg with a layer of 1 cm – 12–19 kg.
• Water consumption per 1 kg of the mixture – 150-400 ml.
• Thickening time of ready -made collapse from 30 minutes to 6 hours., It depends on the composition of the mixture.
• Frost resistance – up to 50 cycles (freezing and thawing).
• Temperature for use from +5 to +30 degrees.
• It is allowed to use a plastered wall after 3 days.
• Preservation period 1 year.

It is not possible to print bags with the mixture and pour it into another container to extend the shelf life. The remaining mixture material needs to be carefully wrapped in a plastic bag and fastened securely. As a result, you will give the term an extra year.

Preparation of the solution

Use a punch and mixer to easily knead plaster. It is preferable to use a container with high sides so that the mixture won’t spill over the sides while being mixed. Dishes should be clean and dry.

Once the dishes are ready, transfer the desired amount of mixture into them, stir in a small amount of water. Pour the remaining liquid slowly. In order to prevent lumps from forming, we beat the plaster until it has an elastic consistency.

The solution needs to have its viscosity examined after being received. To accomplish this, we will take a small amount of mass and turn it over. If the mass falls off the tool without holding onto it, the solution is liquid, and a dry mixture needs to be added. If the mixture is excessively thick, we add water and recheck it.

Cement-lime plaster combines the workability of lime with the strength of cement to create a durable and adaptable wall finishing option. This mixture works well on a range of surfaces because of its exceptional adhesion qualities. Additionally, it offers an even, smooth finish that is perfect for walls on the inside as well as the outside.

Breathability is one of the main advantages of cement-lime plaster. The lime component lowers the possibility of mold and dampness by allowing moisture to escape the wall. This helps preserve the integrity of the wall structure and is especially crucial in places with high humidity or notable temperature swings.

Cement-lime plaster has several practical advantages in addition to being reasonably simple to apply. Because it just calls for simple equipment and knowledge, both expert builders and do-it-yourselfers can complete it. Additionally, the mixture is flexible enough to accommodate alterations and smoothing during application.

Cement-lime plaster is a great option overall for people looking for a dependable and long-lasting wall finishing solution. It is a well-liked alternative in both residential and commercial construction because of its blend of toughness, breathability, and simplicity of use. You can be sure that your walls will stay sturdy and aesthetically pleasing for many years by selecting this kind of plaster.
