Facade decoration is not only the hallmark of the house, but also the protection of its walls from moisture, cold and other unwanted influences. Therefore, in this case, it is necessary to approach the choice of material as responsibly as possible. Want to get a beautiful and durable exterior wall finish without overpaying? Then the fiber cement panel for facades is your choice. Here you can find out what kind of material it is, how it is produced, what happens and how to work with it correctly.

Fiber cement boards
Fiber cement panels are a finishing material of artificial origin, produced in the form of slabs or siding.
Consists of 85-90% cement and 10-15% mineral additives and fiber - cellulose or synthetic fibers. The last component of the material plays the role of a reinforcing component that imparts flexural strength to fiber cement panels. Outside, they have a weather-resistant coating that imitates brick or masonry. Also, the composition of fiber cement panels includes water repellents - additives that simultaneously protect the material from moisture absorption and allow it to "breathe", remove small particles of water outside and not dampen it.

Fiber cement slabs and siding were created at the beginning of the last century as an alternative to plaster.
The new material was supposed to surpass it in many performance characteristics and be easy to manufacture / install.

Let's take a look at the example of LATONIT fiber cement panels with the technological process of production of this finishing material.
Step 1. Mix cement, sand, cellulose and other components of the finishing material together.
Cement - one of the components
The resulting mixture enters the molding department and is rolled out to a still wet layer of a certain thickness.

Important! Often, a rather complex coating is applied to the surface of fiber cement panels, imitating real stone or brickwork.
The manufacturing process of fiber cement slabs is completed by culling, packing and sending the material to the warehouse.
By their appearance, fiber cement panels can be divided into the following groups.

Important! Some of the fiber cement panels are produced unpainted - this stage of finishing the facade must be done by the owner of the house himself. On the one hand, this will allow you to choose the color that you, for some reason, did not find in the manufacturer's catalog.
But at the same time, you will need to spend time and effort on applying paint. It is also worth noting that the cost of such unpainted fiber cement panels is 10-20% lower than the fully finished material.
The durability and appearance of fiber cement facade panels directly depend on who produced them and on what equipment, as well as with what care the manufacturer followed the technological processes. In total, eight manufacturers can be identified who are considered leaders in this area in the construction market in the CIS. You can familiarize yourself with them from the table below.

Installation of facade panels with your own hands
Not every homeowner allows his financial state to improve the house with stone tiles or decorative bricks.
It's not only the cost of materials, but also the complexity and high cost of the installation. There are special facade panels for insulation and making the house more aesthetic. Read more here.
Before proceeding with the installation of fiber cement panels on the facade of a building, we will consider some features of working with them - cutting , drilling and storage. Let's start with panel cutting, which may become necessary when working with corners, slopes and the space under the roof of the cottage.
Step 1. The cutting line of the fiber cement panel is marked. She herself is laid on a flat surface face down. A soft material is placed under the panel to protect it from scratches.
Preparing the fiber cement panel
Prepare the cutting tool. It is best to use a circular saw for this. In this case, a product with a guide rail, automatic feed and dust extraction is used - with the help of these devices, a neat and fast cut of the fiber cement panel is achieved.The circular saw blade must be positioned so that at its lowest point it runs 5 mm below the sheet of finishing material.
Circular saw blade location
The circular saw turns on and the cutting process begins. Its disc runs along the entire length of the fiber cement panel. Then the cut part of the fiber cement board is separated from the base sheet.
Step 4. Wipe the surface near the cut of the fiber cement panel to remove the dust formed during the cutting process with a dry cloth.
The surface near the cut is wiped with a dry cloth
Drilling the fiber cement panels should not cause you any problems. The main thing is to comply with several conditions.
There are engineering communications in every house, in some cases they go out not underground, but above it.
In such a situation, it becomes necessary to cut round holes in fiber cement panels. You can see the process in the photos below.
First, markup is carried out - a circle of the required diameter is drawn. Then a hole is drilled at its edge
An electric jigsaw blade is inserted into this hole, the tool itself turns on. The cutting process begins - the jigsaw is slowly advanced along the line.
After the edge is wiped from dust with a dry cloth
Fiber cement panels should be stored in a dry room and strictly in a horizontal position. It is undesirable to put plates on the ends - they will deform. It is imperative to put pallets or wooden blocks under the stacks of fiber cement panels.
Rules for carrying fiber cement panels
Let's present a step-by-step instruction, which sequentially outlines the process of installing fiber cement panels on the facade of a house.
The installation of fiber cement panels begins with the preparation of the wall. It is cleaned from the remnants of old finishes, dust and dirt.If the house is made of bricks or foam blocks, they get rid of the excess cement mortar between them. Then, using the level and beacons, it is determined how flat the wall is, whether there are any defects on it that need to be considered in the future.
The evenness of the wall is determined
Marking is applied to the wall for the installation of brackets on which fasten the frame for finishing from fiber cement panels. The spacing between the brackets vertically and horizontally is selected based on the project and the material used.
Step 3. According to the marks made in the previous step, holes are made for anchor fasteners. Their depth is selected based on the wall material and the mass of fiber cement panels that will be used for finishing.
Step 4. Brackets for the fiber cement frame are assembled, mounted on the wall with anchor bolts. Then the length of their working part is adjusted according to the plumb lines that were made in the first step. This parameter depends on the thickness of the intended insulation layer.
In this illustration, you can see that between the bracket and a paronite gasket is present by the wall - it reduces heat loss at the point of fastening and slows down the corrosion process of the metal product
According to the principles described in the previous operation, all brackets are installed on wall.
Installing the remaining brackets
Step 6. A layer of mineral wool is placed on the main wall. In this case, cuts are created in the material for the brackets. The fixation is carried out using disc dowels, driven over the entire surface of each individual mineral wool slab.
At the same time, the insulation is laid with overlapping vertical joints like brickwork. This is necessary to improve the thermal insulation properties of the layer and eliminate "cold bridges".

Insulation boards must be laid in a checkerboard pattern
Step 7. The vertical profile of the frame is fixed to the brackets. Their final connection is made with rivets.

Step 8. The rest of the vertical profiles are installed in the same way. They are connected to each other using a busbar and rivets, as shown in the illustration below. It is necessary to leave a small gap between the abutting vertical profiles to compensate for the thermal expansion of the metal.

Step 10. Fiber cement panels are fixed to the frame by screwing screws in the corners ..

Step 11. One screws for fixing fiber cement panels for the facade is not enough - it is necessary to supplement them with skids installed in the vertical profile. They are fitted to the corresponding panel details.

Another panel is attached to the side. Its fixation takes place according to the same principle - first self-tapping screws in the corners, then fitted skids. But at the same time, a small gap is maintained between adjacent panels, designed to compensate for the increase in facade decoration for one reason or another and to prevent its warping.
Installing the second panel
Step 13. Next, install the rest of the fiber cement panels for the facade.
There should also be some gap between them.
The rest of the fiber cement panels for the facade are installed
Step 14. The slopes are trimmed separately. There are two options here. In the first case, the slopes are closed with metal painted products, in the second - with pieces of fiber cement panels.
The joints at the corners are treated with a sealant.
After that, finishing with fiber cement panels of the facade of the house can be considered successfully completed.
