The main types of facade stucco molding

Depending on the form and purpose, the facade stucco molding is divided into the following types.

  1. Pilasters and columns . Most often they are mounted at the entrance groups, sometimes they are installed on large open balconies.

    During installation, they must necessarily abut against the surface; they are rarely installed in a suspended position. It is recommended to involve professional builders for installation, it is very difficult to do the work yourself without practical skills.

  3. Bas-reliefs and decorative panels . Installed above the canopies of entrance doors, can be used to decorate the front walls of the second floor. Such work can be performed independently, does not require much knowledge, costs and efforts. Problems can arise when finishing the facades of multi-storey cottages. For installation, you will have to specially install scaffolding, preferably work with an assistant.

Gypsum

The material does not have a harmful effect on the environment, in terms of physical strength takes the middle place. Gypsum has a high manufacturability - the cost of products decreases, the possibilities of sculptors expand.

The relatively small weight allows the use of simplified technologies when fixing the stucco molding on the facade walls.

High hygroscopicity is the main disadvantage of gypsum. Another problem is fragility. With insignificant impact forces, the gypsum crumbles or cracks, the figures have to be repaired. To protect against moisture penetration, modern impregnations and protective coatings must be used.

Installation on open facade walls is highly discouraged; it is better to install in places protected from atmospheric precipitation.

Polyfoam, polyurethane foam and other foamed polymers

The lightest, in most cases it is fixed only on adhesives with high adhesion to building materials. For the manufacture of stucco molding from polymers, brands with small sizes of air bubbles are used, due to this, the strength slightly increases. In terms of cost, they belong to the cheapest segment. Very low strength.

In this regard, such stucco molding is recommended to be installed at a height, in places that minimize the risk of mechanical damage. Another drawback - for unknown reasons, birds really like polystyrene, and therefore no precautions will save the stucco from damage.

Concrete and polymer concrete

The most durable , beautiful and durable products. Most often they have classic forms and motives. The service life is calculated in many tens of years.

The most expensive stucco molding, has a large mass and requires special construction measures during installation. The production technology is complex, such stucco molding can only be produced by large companies with modern equipment and highly professional specialists.

Another example of facade molding

Stucco molding can be bought ready-made or made by yourself. But in all cases, the surfaces must be additionally processed. How to improve the appearance of decorative elements?

  1. Painting and varnishing .

    You can use the classic method - paint products to match the color of the front walls. If you want to experiment, use contrasting paints. The stucco molding covered with patina looks original, you can imitate gilding, make various textures on surfaces.

  2. Cover with wax . This method can be used to protect plaster and concrete stucco moldings from moisture penetration.

    The wax not only protects the decor, but also gives the surfaces a shine. The coating lasts for many years. In a warm period, wax can independently tighten microcracks, which increases the life of the stucco molding.

  3. Artificial aging . Liquid gypsum with mineral dyes is applied to the surface.

    A hard brush with a long bristle is used - the effect of cracks is created; to increase the effect of antiquity, in some places the surface can be wiped a little with a rag. The work requires practical experience, if you do not have it, then you should practice first.

    Facade stucco molding - types, characteristics, DIY installation

    Another way of decorating stucco is patination, i.e. artificial aging of stucco elements to give them exquisite decorativeness

  4. Aquarelle wet .

    On the main layer of not dried paint, a second one with new colors is applied. The border between them is blurred, both colors are visible on the stucco molding. To enhance the effect, the second layer can be applied with foam rubber.

The stucco molding has a "chameleon" effect, and the play of colors is almost never repeated.

Note! We do not recommend making your own stucco molding. This is a long and rather difficult matter. Instead of the desired savings, you can get continuous losses and wasted time. It is much more profitable to purchase ready-made stucco molding, since the choice is huge today.

A wide range allows you to create facades of houses of any style.

As for the finishing decorative finishing, this is not only possible, but also necessary. Stucco molding is sold with an untreated surface, it is necessary to independently select paints and coating technologies.

Important! Due to the fact that the facade stucco is placed in the open air, you should be very careful about its installation. Consider the step-by-step installation instructions.

Installation stucco moldings on the front walls

Remember that stucco moldings that have fallen from the façade often cannot be restored. In addition, re-installation is time consuming and expensive. It is much more profitable to immediately take the whole range of measures to ensure high-quality installation, fully comply with the recommended technologies and materials.

Step 1. Select specific types of moldings and their location.

In principle, there can be no universal advice here, each home owner makes decisions independently or after talking with professional architects and designers. Once again, we remind you that you need to be very careful with plaster molding, its use for facades is limited.

Preparation of decorative elements (in this case - from expanded polystyrene)

Important! When choosing a style for the design of front walls, take into account not only the decor indicators, but also the bearing characteristics of the walls. If the facades are not very durable, then it is recommended to use lightweight polystyrene stucco molding, if the facades are brick or stone with concrete plaster, then elements from any materials are suitable. It goes without saying that the stucco molding can only be installed on cement-sand plaster or facade brick.

Step 2. Prepare the facade. Clean the wall surface from dust and dirt, check the linearity of the plane. The difference in height should not exceed 2 mm per linear meter. If the wall does not meet the requirements, then the area where the stucco will be installed must be leveled.

It is not necessary to finish the entire wall, this does not in any way affect the quality of installation, fix problems only in those areas to which the stucco will be fixed. Level the wall with a trowel, use coarse dry exterior plasters. The more roughness the wall surface under the stucco has, the higher the adhesion strength.

Deep penetration primer application to prepared surface

Professional recommendation. Inexperienced builders often have problems at the junction of a new mixture with an old one - it turns out to be stepped.

This immediately catches the eye and impairs the appearance of the facade. In order to make the joint invisible, rub it with a damp washcloth until the solution sets. Movements should be light towards a clean wall. Make sure that a thin layer of cement-sandy plaster does not lose moisture very quickly.For chemical reactions to take place, cement requires water, otherwise it becomes fragile, a thin layer of new plaster in the winter will surely fall off.

As a result - an extraordinary renovation of the facade wall. If the marriage is low, there are few problems, and if the plaster fell off at a considerable height, then you have to suffer.

Step 3. Make precise marking of the installation locations. The markup depends on the size / type of stucco molding and its location.

Above in the article, we already talked about various types of products, decide on the placement of each of them. If you are mounting long flat structures, then it is better to use a special rope with blue for marking, (with the help of such a rope, lines are beaten off on the surface of the wall along the outer perimeter of the stucco molding). Check the position carefully, use a level. After drawing the lines, move a little away from the building and examine the wall from a distance. In this way, you can check the correctness of the markup.

The next step is marking the installation locations

Important! Pay close attention to the corners, they should all be exactly 90 °. Otherwise, there will be big problems during the installation of the side elements; only professional craftsmen can carefully connect them at different angles. Stucco molding is a rather expensive material, if the first time it is not possible to make the correct cuts, then the piece will have to be discarded and bought a new one.

Step 4. Begin to fix those elements that do not have a bottom stop.

Most often these are window sills. In the future, the following elements will hold on to them, the structure will become strong. To ensure that the stucco molding does not spontaneously fall down along the line during the glue hardening, make several stops. These can be ordinary nails or dowels, the specific choice depends on the material for making the front wall.

Step 5.

Take measurements of the lower cornice, saw off the ends at an angle of 45 °. It is better to use a miter box for work. Foam stucco molding is perfectly sawn with an ordinary hacksaw with fine teeth or a blade for metal. If you have an electric hand saw - great, the work will go much faster and the quality of the cut will improve significantly. By the way, modern saw models have a table with an indication of the cutting angle - installation is greatly simplified and accelerated.

Cutting elements with a red-hot thread

On window openings, it is recommended to install the lower cornice slightly wider than the upper one, and make the end rectangular ...

Step 6. Prepare the glue to fix the stucco to the wall, most often the mass for ceramic tiles is used for this purpose, but you can buy special solutions.

During the preparation of the mixture, follow the manufacturer's recommendations exactly, violation of the technology has a negative effect on adhesion.

Step 7. Using a comb trowel, gently apply the adhesive to the back of the molding and the wall. If the weather is very warm, then the section of the wall must first be moistened with water.

Step 8.

Press the stucco molding against the wall as tightly as possible, remove the glue that has come out with an even, clean spatula. Make sure that the bottom edge rests against the nails and the molding does not slip.

Step 9. Attach the upper part of the decor to the wall, mark the cutting points under an angle of 45 °. Make a cut on a miter box.

If you do not have a factory one, then you can make the device yourself. To do this, you need several pieces of flat edged board or plywood. Connect them with the letter P, in the side edges make cuts at 45 ° in two directions.

Step 12. To increase the strength of the fastening, it is recommended to fix the stucco in several places dowels.

To do this, drill holes in the elements and the wall, fix the dowels, and seal the visible holes with silicone.

Important! Remember that some brands of silicone can shrink during solidification, do not rush to immediately paint the surfaces of the stucco molding. If small depressions appear, then they should be repaired with silicone. After the stucco molding is fully glued, the lower support stops can be removed, and the holes in the wall can be repaired using the usual method.

Wide gaps between the individual elements can be sealed with polyurethane foam.

Before that, clean them of dust and moisten them a little. Blow the foam into the gap, allow time to harden. Next, cut off the protruding part with a sharp assembly knife, level the surface with silicone.

Note! We talked about the simplest way of attaching stucco over window openings. The technology for fixing the rest of the types has no fundamental differences, only the location of the decorative elements changes.

Features of installation of facade plaster moldings

It is not recommended to use it for decoration of facades.If you have such a desire, then you need to protect the surfaces as much as possible from the penetration of atmospheric precipitation. When freezing, wet products will surely crack. If you do not want to use waterproof, but cheap and fragile foam plastic stucco molding, then it is better to lose more money and purchase concrete or polymer concrete products.

Gypsum stucco

Gypsum stucco molding is much heavier than foam, such material properties make certain adjustments to the installation technology.

  1. Gypsum stucco molding should be installed only on a solid supporting base, facade walls should be plastered with cement-sand mortar. Tap them, check for voids. If a "drum" sound is found in some places, the plaster has peeled off. These areas must be removed without fail and a new layer of plaster should be applied. Further work on the installation of stucco molding can be continued only after the final hardening of the solution.

  2. For better adhesion, it is recommended to make grooves or shallow indentations on the surface. You can work with a chisel with a hammer, a hammer drill or a grinder with a diamond disc. Use the latter option last, it has many disadvantages. Firstly, the width of the cut grooves does not allow the adhesive mixture to fill them completely, as a result, the efficiency is significantly reduced. Secondly, it is very difficult to remove dust from the furrows, and its presence lowers the adhesion coefficient to almost zero values.

    Thirdly, the dust from the grinder settles on the wall and all architectural elements; you will have to waste time to clean it.

  3. The back of the plasterboard must be leveled and the dust removed carefully. Work very carefully, remember that plaster moldings that have fallen from the facade cannot be restored. And many elements can be made manually in a single copy, this greatly complicates the restoration of the original appearance of the building facade.
  4. The surface of the plaster does not have the required strength and is easily crumbled.

    To improve performance, it must be impregnated at least twice with special deep penetration primers. Penetration depth is at least 2 mm.

  5. Use only special adhesives to fix the elements. They are prepared from PVA leu, water and gypsum. Gypsum grades G10 or G7, proportions - 40% glue and 60% gypsum, water is added as needed, the consistency of the mass should resemble thick sour cream.

    The use of dowels is mandatory, the holes from the hardware are sealed with prepared glue.

Wall finished with plaster, depending on depending on the type of material, it can have a different texture, color, look modest and inconspicuous, or, on the contrary, very expensive. Marble decorative plaster is one of the types of decorative surface finishing. It is used for various purposes, including for facades.

Concrete products must necessarily have an emphasis; they are not fixed when suspended to the front walls.

If the concrete stucco molding is large, then during the installation of individual parts, construction reinforcement is used to increase the strength of fixation.
