How to apply sealant

The guarantee of a highly sealed seam is hidden in proper preparation and possession of simple skills. Studying the appliances of the sealant will save from a heap of trouble: a stubble, flowing design and discarded clothing.

The main tool when working with the sealing compositions of the finishers consider a spatula of rubber or plastic. Its form is different - in the form of a spoon, rectangle, or the other, most suitable for the seam processed. For a start, there are enough two or three spatulas, and later you can get a set with blades of various radii. Also, you will also need:

Pistol for sealant;
Soap solvent pulverizer;
Painting tape, rag;
Acetone or alcohol.

Brand sealant Selected depending on the materials being processed:

Silicone applied in wet places (Tytan, Pulp);
Acrylic, for example, Lacrysil - is suitable for most uniform connections;
Polyurethane close cracks with subsequent staining - CAZILAST 13;
Latex - for wood ("Consil").

Apply the sealant is allowed at a temperature of + 5 ° C and above. The working surface is prepared: the dust is removed by a vacuum cleaner, wet and deep seam is dried with a hairdryer. When re-sealing the compound is performed, the old composition is first removed:

Mechanically using a sharp knife, blade or scraper, the main part is cut, and the residues are signed by a rigid grater;
The chemical method is covered with a special wash or white spirit, after softening, the old sealant is removed by the rag.

During cleaning, they are trying not to scratch the surface, when using chemical solutions, their impact on materials is first checked.

Make the joke neat will help the greasy tape passed by two strips along the edges of the seam. Subsequently, the tape is easy to remove, and it will not be necessary to remove excess. Surfaces are processed - the sealant is prepared:

At an angle of 45 °, the tip of the nozzle is cut off, the resulting hole must correspond to 2/3 seam sample;
The nozzle turns into a tube, a protective foil is skewing a wire several times;
By clicking on the trigger, it is put forward to the end of the piston, the cartridge with a sealant is placed in the gun housing;
Filled nose of tubes, working as a lever.

In the process of filling the joint, an angle of 30-45 ° is withstanding between the gun and the plane, while the nozzle is slightly touched by the surface. Promoting the tip along the seam, it creates a continuous, smooth roller. The degree and frequency of presses on the lever correlates with the speed of movement of the pistol. With too fast movement, the roller will be intermittent and thin, if promoting a slower pace - the overrun and smeared surplus will appear. At the end of the squeezing, the sealant of the trigger is released and the pusher rod is released. Nose wiping with a rag and closed with a cap.

After the imposition of the roller remains 10-15 minutes on its formation. The junction splashes with soapy and passed by a spatula. The tool holds exactly, without tearing off the plane, the grout is performed - if the movement was interrupted, it is necessary to repeat again. Schaw smoothing guarantees high-quality filling of emptiness and beautiful view of the connection site. It remains to remove the protective strips of paper and wait for the complete hardening of the composition - usually at least a day.
