One of the oldest and most tested types of finish is plaster for outdoor work. It protects the building from the destructive effect of rain, sun, frost, improves the thermal insulation of the wall and gives the structure aesthetically attractive appearance.
Types of facade plaster for exterior works
This construction mixture consists of a binder ingredient and any filler, depending on the components, different types of facade plasters are distinguished, they can be divided into:
- Normal - used to align the base planes. In the future, the wall is covered with paint or varnish. The main types: gypsum, cement-sand.
- Decorative - are relevant at the final stage of facing.
- Special - apply for additional protection, can have a different effect. Their varieties:
- Waterproof - protects from moisture.
- Soundproof - protects from noise.
- Winter plaster for outdoor work - protects against frost during the cold season.
Warm plaster for outdoor works
Insulating plaster for outdoor works is done on the basis of cement, as a filler are granular foam, expanded clay, crushed pumice, perlite sand. These porous materials increase the heat-insulating properties of the mixture, to apply it easily on different surfaces - from wood to concrete. The layer forms a vapor tight, does not absorb moisture, the fungus does not live on it, mold does not appear.
Frost resistant plaster for outdoor work in winter as much as possible reduces heat leakage outside the building, and in summer - does not let the heat in. As a result, the cost of heating the home is reduced. According to the producers, two centimeters of warm plaster for thermal insulation qualities are identical to brickwork by a layer up to half a meter. The mixture can serve as a finishing finish - for this, it must be covered with vapor-proof paint.
Dry plaster for exterior works
Considering different types of plasters for outdoor works, it is necessary to highlight a dry finish. It is an ordinary plasterboard, consisting of gypsum, paper and starch, bonding the mixture. The advantage of the material was its versatility, after installation it is easy to carry out further facing of the building by means of different techniques - be it paint, plaster, panels.
Drywall is convenient for leveling walls, it improves the sound and heat insulation characteristics of the building, which positively affects the comfort of living. It is environmentally friendly material, does not release toxic substances when heated, it is resistant to high temperatures. The sheets are fixed on a cement or gypsum base, they stay well on the walls for a long time.
Moisture-resistant plaster for outdoor applications
Water repellent plaster for outdoor work in the base has special polymers, creating a protective layer. It is done on the basis of:
- cement;
- gypsum;
- silicone.
Water repellent mixture is designed for operation in conditions of abundant humidity. The application of such a layer is advisable in the presence of sharp temperature differences between the air inside and outside. It will protect the base from damage during prolonged atmospheric precipitation. The mixture will protect the facade of the building from condensation, freezing and keep the heat inside. The valuable quality of the composition is an impeccably smooth received texture, the walls are immediately suitable for further painting or coating work.
Granite plaster for exterior works
Mineral granite plaster for outdoor works is a multi-colored durable mixture with natural quartz particles in the composition. It is made on the basis of synthetic resins, saturated with plasticizers and additives. Granite plaster walls for outdoor works has unique characteristics:
- high waterproofing;
- antibacterial;
- high impact resistance and wear resistance.
The mixture is quickly applied to the walls, looks like a mosaic rough surface with a grain size of up to 3 mm. Granite plaster has the natural color of granite chips, many of its tones are on sale. Using granules of different shades, it's easy to create beautiful insets, squares, stripes, rhombuses on the facades, which will give the structure a unique appearance.
Gypsum plaster for outdoor works
A gypsum-based mixture is often used as a leveling plaster for outdoor work and preparation of plots for finishing. Its advantages:
- high elasticity;
- low tendency to crack;
- frost resistance;
- environmental friendliness.
In facade compositions to the gypsum component manufacturers add polymers, minerals and modifiers, which strengthen the strength of the plaster, its adhesion to surfaces and elasticity. Due to this, the mixture becomes more resistant to negative influences. Compositions are often used for leveling gypsum-concrete planes, brickwork.
Cement plaster for outdoor works
Traditional cement plaster for outdoor works is a budget option for finishing the structure. A similar composition is often used to level the slag-block or brick walls. The layer gives the aesthetic appearance of the structure and enhances its sound and heat insulation parameters. Cement mass is represented by two types:
- Cement-sand plaster for outdoor works is the most common type of finish. Its main advantage is high strength and versatility. The basic ingredients of the mixture - cement and sand, different types of additives make it more elastic. The solution is considered moisture and frost-resistant.
- Cement-lime mixture, in addition to traditional ingredients, lime is added to it.
Acrylic plaster for outdoor works
Considering different types of plasters for outdoor works, it is necessary to highlight acrylic mixtures. They are a mass with a thick paste-like consistency, sold in buckets. This type of coating has a long service life, acrylic resins play a decisive role among its components. The material is immediately applied to the surface, very elastic and helps to hide even the smallest cracks.
Due to the fact that the mixture is ductile and can stretch slightly, it is not afraid of shrinkage and cracking. Another plus of acrylic coating is the saturated and persistent color of the material. But it is vapor-proof and can be covered with mold if the humidity is high and the air circulation is insufficient. Therefore, it is advisable to apply acrylic formulations only to foam.
Lime plaster for outdoor works
Structural plaster for exterior works based on gypsum or cement is often supplemented with lime. The rate of its application is 2 kg per bucket of solution. The powder is dissolved in water beforehand to obtain a liquid milk mixture. With the addition of lime, the cement or gypsum mass acquires positive qualities:
- Excellent adhesion - the mixture perfectly lays on concrete, brick, even wood, it is better leveled.
- Plasticity - it is easier to apply such a solution, it retains compliance for 2-3 hours, you can work with it slowly.
- Resistance to fungus - lime gives the composition antifungal characteristics, it can be used in conditions of high humidity.
- Increases the strength of the solution - it serves a long time.
Decorative plaster for outdoor works
Facade decorative plaster for outdoor works is used, as a rule, at the final stage of facing. After its application, the walls acquire a complete appearance. To make it attractive texture will be useful spatula, graters, rollers, stamps. This type of plaster for outdoor works has its own varieties, differing in relief, texture, color scale.
Plaster "bark beetle" for external works
Facade plaster for exterior work "bark beetle" is structural, is a light-colored powder, has in the composition of fine or coarse-grained mineral granules. Due to the impregnations when applying a grater on the wall, furrows are made, resembling the bark of a tree, damaged by insects. Variants of patterns:
- Rain is done by moving up and down.
- Lambs - are made with the help of movements in a circle.
- Crosses - spatula move crosswise.
"Bark beetle" is popular for facade finishing due to its good solution viscosity and adhesion to the wall plane. The surface is shockproof and frost-resistant, it is not afraid of ultraviolet, wind and rain. "Bark beetle" breathes well, the fungus does not appear on the walls covered by it. Such plaster is made white, but before applying it it is easy to tint with the help of pigment additives or paint over with water-emulsion paint.
Plaster "hedgehog" for outdoor works
Sprayed plaster for external works "hedgehog" is an ordinary cement-lime mixture with the addition of sand, granulometric composition and special chemical ingredients. It is used to level the walls of concrete, brick for subsequent cladding, can be used as a spray or a primer. Allowed for such a composition and machine application of the solution.
The mixture is diluted with water, applied in several layers with a thickness of each of 5-8 mm, is perfectly smoothed due to the high compliance of the material. Even complex areas (corners, architectural reliefs) become flawless after the spraying of such a solution. The material has a high adhesion and does not shrink after drying, does not form cracks.
Venetian plaster for exterior works
There are different types of decorative plasters for outdoor works, the Venetian among them occupies a special place. The mixture is made on the basis of marble chips, it is applied in several layers (at least seven), after which it is rubbed with wax. Externally, the plane obtained has an ideally smooth texture, reminiscent of onyx or marble, it conveys the smallest veins of natural stone, sometimes it is difficult to distinguish a Venetian from a real material.
Due to the use of wax, a special depth of color is achieved and a glow effect is created from the inside. Venetian is widely used for interior decoration, but thanks to the addition of acrylic resin it is used to ennoble the facade. This cladding not only gives aesthetic appeal to the exterior of the building, but also protects the walls from the harmful effects of atmospheric precipitation, and the structure - from heat loss.
Stone plaster for exterior works
Textured plaster for outdoor works is popular and budgetary, as a filler it uses small pebbles, mineral crumbs, wood fibers, mica. Thanks to them, a three-dimensional surface is formed, different instruments are used to enhance the effect. Often, such decoration recreates a natural stone, no less popular is the imitation of granite, wood, clothed fabric.
In its raw form, the mixture is a white mass, which is pigmented or after application is covered with paint. An important advantage of textured plaster for outdoor works is its plasticity and high viscosity structure, thanks to them on the surface and the required relief is formed using spatulas, ironers, stencils, rollers. The resulting layer has a hardness and water resistance.
