Despite the fact that the roof covering ofAsbestos-cement sheets are distinguished by their durability after decades, external atmospheric and climatic factors exert their influence on the material. Something has to be replaced, something to repair, somewhere to block. Here, knowledge is required in the field of construction, and if you know how to repair a crack in the roof slate, then such work will not seem difficult.
Cosmetic repair works will help to prolongThe operational life of the roof for a period of up to 10 years. Therefore, the topic is especially relevant. In the past, the roof was sealed using oil paints and fabric strips. This technique was not famous for its special effect, and the state of the overlap was improved only for a couple of years. Today, in free access, modern materials that make the process of eliminating cracks and chips on the roof are more effective.
The flow of the roof indicates damageintegrity of the material. To get rid of this problem, you can use one of the effective methods. Any of them is easy to apply in practice and does not differ in complexity, but here it is important to know what to seal a crack in the roof slate. In 90% of cases it will be necessary to install a patch or seal the affected area of the roof.
Read the options for action in the event of a roof, the easiest and fastest method of eliminating leaks, the technique of slate patch. It is important to talk about such details well in advance.
The most common technology for the restoration of asbestos-cement damaged sheets is the use of asbestos paste.
Using an asbestos paste to seal the cracks, take care of the preliminary dismantling of the damaged roof fragment and lower it to the ground.
The mixture consists of two components: asbestos and cement. Such pasta is easy to prepare at home.
Components:
Water and glue can be added as needed, until the paste has a creamy consistency.
For preparation:
Knowing how to seal a crack in the slate on the roof,you can start work. Try to use the cooked paste immediately. As storage, the composition loses its properties. Therefore, prepare as much grout as you need to repair the roof of the house.
Before you seal the roof, prepare the damaged area:
The composition is applied to the damaged areagradually, evenly spreading over the surface of each of the layers. The total thickness of the applied paste should be at least 2 mm. After the patch has dried, the stitch must be treated with sandpaper.
Carrying out the restoration, try to cover it up,so that the coverage area spread beyond the crack. After repairing the sheets of broken slate, you need not worry that the roof will leak for the next 8-10 years.
Asbestos paste is not the only optiontreatment of injuries formed on the roof of the house. If you do not know how to seal a crack in the roof slate, use foil instead of the paste, which is applied a bit of universal glue and applied to the damaged place from the wrong side. A tight fit of the patch is provided by rounding the corners, so they curl less. The joining of the foil from the reconstructed surface is obtained durable due to the universal adhesive used and reliably protects the internal space of the attic from the penetration of water and moisture.
If you want to seal that part of the roof where the fastener place passes, then seal the crack with foil and drill a hole under the fasteners in the other part of the sheet.
After repair, the removed slate sheet is mounted on thea place. Do not forget to use special rubber pads under the nails to protect the corrugated board from damage during the installation. Having finished the reconstruction, disguise the patch to the tone of the roofing material. At this stage, work is carried out in dry weather, and when applying paint, use a brush or roller. It is better to apply several layers, starting to re-paint only after the first one dries completely.
Some of the methods do not imply dismantlingdamaged products in the place where the slate burst. How to repair a crack, if you need to go up, read on. Such work is done directly on the roof, and for this it is vital to provide insurance.
Often, silicone paste is used to repair the roof. The agent is characterized by high adhesion to materials made from asbestos cement.
Getting to work, the damaged areaprepare: cleaned of dust and small mud crumbs, using a brush for cleaning metal products. To do this, use acetone or a special solvent.
Before sealing the crack, it is filledcrushed asbestos crumb, which is subsequently filled with silicone glue for slate. This restoration is not difficult, and the whole process takes a maximum of 24 hours and ends at the stage of tinting the treated area under the general style of the roof. At the same time, coloring plays not only an aesthetic role, but also gives the connection additional reliability. Coloring in this case is simply necessary. The top layer allows to fix a multilayer patch, because the asbestos-cement sheets themselves are porous.
It is important to remember that at the joints slate sheets are processed with mastic with a special reinforcing filler of a wavy structure.
Bitumen is melted in a separate container, pre-chopped. The foam and impurities formed in the process are removed. The melting process takes place at a temperature above 200aboutC until the bitumen is completely dehydrated. Grout consists not only of bitumen, a filler is added to the composition, which is preheated to a temperature of 110aboutFROM.
Mastic in hot condition, using a spatula or other suitable tool, is applied to the prepared surface for repair.
Sometimes to repair damaged sheetsuse a kind of rubber paint for slate. The agent has increased adhesion and strength properties. This method of rebuilding slate is gaining popularity.
Applying for restoration of mounting foam, slatepre-clean and degrease. Foam is poured into the formed crack, but leave a little space for the sealant, which after hardening of the foam is squeezed out by a dense layer over the foam. On top of the formed lacquer is applied bitumen mastic, which helps to seal a crack in the slate and protect the inner space of the attic from the penetration of atmospheric precipitation.
Now you understand the complexity of slate repair. Than to seal holes and cracks - you know, you understand in details, and after all it is the main thing at carrying out of restoration works with асбоцементными sheets.
