Among the many kinds of insulating materials, which are represented in the construction market, especially popular rock wool. This unique product has a number of positive aspects. But in order to achieve the desired result, it is necessary to know how should be done laying mineral wool and how to grout.
Mounting mineral wool
At the present time there are several varieties of this insulation. The best mineral wool for laying under plaster is glass. It is flexible enough to have a good margin of safety, and has an excellent heat insulation performance.
In order to insulate and ennoble the facade, you can use cotton wool in rolls or in the mats. Surface finished in this manner, not only provide a complete air exchange, but also protect the premises from penetration of outside noise from the street. With proper installation material will significantly reduce heat loss in the winter season and in summer the building will not allow excessively hot.
Important! Plaster or other finishing mineral wool can completely protect the material from damage.
In order to properly carry out installation work, it is necessary to prepare such tools:
- Plastic dowels with a maximum wide hat;
- adhesive solution;
- hammer;
- drill.
Before starting to fix mineral wool, thoroughly clean the surface from various debris, dust and dirt. If the walls are chipped and cracked, they definitely need to be aligned. Only then you can proceed to substantive work.
In order to glue the mineral wool, you must first install guide. An excellent embodiment are metal profile. If you can not buy such a product, you can use pieces of wood. Horizontal guide should be mounted at the bottom of the wall. The width between the element and the ground plane should be no less than 60 centimeters. Profile should be secured with dowels.
Fixing mineral wool is performed on a prepared adhesive composition. Apply the mixture on the whole plate surface. This should be done spatula. In carrying out this work, it is necessary to pay attention to the fact that the thickness of the glue on the entire surface was the same.
After the insulation will fit snugly to the surface, you can start to fix mineral wool with dowels. On each plate is necessary to make five holes (four at the corners and one in the middle). This will allow to avoid further deformation of the insulation. After their arrangement, all the speakers need to cap cover adhesive solution.
Important! Laying any mineral wool technology involves the mandatory use of dowel-fungi.
After finishing the entire surface can proceed to laying of the reinforcing layer. Attach the grid should be on the adhesive solution. After depositing a thin ball web require good squeeze around the perimeter. To be safe, do not need to whipping on each side at least 10 centimeters. Once the mixture is dry, you can begin to plaster wool.
Correct handling of different types of mineral wool, will provide a solid surface, which serve no one ten years. The main thing is to comply with simple rules and recommendations.
How to choose the plaster structure?
To plaster mineral wool, it is possible to use different mixtures. It is important to bear a good raw material, and not create difficulties in the process.
To obtain a firm layer in the 3 mm thick are used these types of solution:
- Silicone plaster. Mixture sold as a finished product. Plaster on the mineral wool insulation has many advantages. It can not be exposed to mechanical damage, water-resistant and does not fade in direct sunlight. The surface-finished by a method such well passes steam but is also capable of self-cleaning during the rainy season.
- Composition of white cement. Sold in dry form. Different solution is a good vapor permeability, which is very important for mineral wool. Also of note is the durability and low cost structure.
- Polysilicon (silicate). This plaster is perfect for finishing mineral wool. It sold as a finished product.
Least often used acrylic blend. This is due to the weak performance of vapor permeability. In addition to its lack of such a plasterer it has several advantages. It is highly resistant to mechanical damage and can not burn in the sun.
In order to save money, often the owners have resorted to a solution applied to the mineral wool cement mixtures. Since such compositions have a gray hue, hereinafter they require painting in the desired color.
Application of the plaster on mineral wool
Finishing Technology façade insulated with mineral wool involves the use of two layers - the reinforcement and the plaster. The durable grid based on glass fiber is used as the first layer. This material must have maximum values alkali-resistant. With such reinforcement coating acquire maximum strength. Also, fiberglass mesh provides excellent adhesion between all the layers.
Armirovochnogo top fabric should cause a small layer of a special primer. Often it is sold together with plaster. It can be purchased separately.
Important! Use other kinds of primer is not recommended, as they do not provide the necessary adhesion.
Once the primer is well dry, you can proceed to the application of top coat. To do this, use a wide spatula. The layer thickness should be not less than 3 mm. If you do not adhere to this indicator, the facade soon will become worthless.
For those who decided to plaster mineral wool acrylic blend, the work should be carried out as quickly as possible. This will get the same shade in all areas.
Plastering important to pay special attention to the corners of the building, the windows and doorways. At these sites should be mounted additional layer mesh. Also, be aware that any type of mineral wool plaster should be carried out at a temperature not below +50FROM.
If you decide to give the surface an unusual texture, you can apply the mixture with the addition of mineral fractions. This small stones, which size is in the range of from 2 to 3 mm. In the process of rubbing on the surface of such fillers will be small, randomly located mattock.
Regarding the establishment of "coat", then for work, you can use a roller or trowel. In the second case, the tool will need to firmly attach to the surface and pull sharply.
To create texture "lamb" only need to use a cement-sand mixture. To finish in this case applies pneumatic ladle. Thanks to him, the composition falls perfectly and evenly covers the surface.
If properly apply the plaster or wet facade, as it is called, you can get a solid and secure surface. This finish not only last for years, but also radically transform any building.
