The amount of sand that must be mixed into the clay depends on its fat content.

If this ratio is high, the proportion of constituents of the mixture should be 1: 3 or 1: 4. To increase the strength of plaster mortar based on clay often added asbestos fibers or chopped glass fibers (0.1-0.2 parts).

Qualitative solution should be easily applied to the surface thereof and good tooled.

It should be said about how to properly plastered. Before starting work the front surface of the structure clean from dust, contaminants and residues masonry mortar. In order to improve adhesion of the solution with brickwork, will clear its seams to a depth of about 0.5 cm. Immediately before the liner to heat and apply the solution onto the warm walls.

Instructions for the preparation of the most common types of plasters (in parts):

  1. clay - 1, sand - 2, asbestos - 0.1;
  2. clay - 1, sand - 2 cement - 1, asbestos - 0.1;

Sackcloth, you can replace the thin steel reinforcing mesh with a mesh size of not more than 1 × 1 cm. Attach it to brick wire thickness of 3 mm. Note that the start it in each of the rows of masonry necessary to advance further in the construction.

After the plaster solution is completely cured, it is coated with a salt of lime milk (about 100 grams per bucket).

Important! Use oil-based paints are strongly recommended as being heated, they are destroyed, and linseed oil burns.

Regardless of what you decide to plaster the stove, performing her trim, you should get the following results:

  1. Deviation surface of the structure from a vertical plane over the entire height should be no more than 1 cm.
  2. The comparable figure across - less than 2 mm.
  3. Rod Deviation between angles from the straight line - no more than 3 mm.
  4. Changes from a flat plane, which are detected when applying the rules of 2 m length should not be more than 2 mm.

If grouting is colored, choose a uniform color bricks. In the process of constructing the front surfaces of the furnace seams leave unfilled to a depth of 1 cm.

Made masonry wiped with a damp cloth and polished with a piece of brick. In the course of this work, all the projections, chips and gouges should flatten.

White cement mixed with asbestos flour, dilute with water and rub a hand in a rubber glove into the seams. Aesthetic decorative masonry depends on the uniformity and straightness of the seams, so to embroider them with the rules.
