How to seal the crack in the wall of brick

Damage to masonry due to the following reasons:

  1. primer having a non-uniform structure after a certain time settles.This leads to cracks.
  2. The same effects are changes in the deformation of the foundation, which are formed in the case of lack of penetration or accommodation close to groundwater and increased load on the walls from ceilings.For 12 months after construction of the building shrinkage occurs, which also provokes the formation of cracks.
  3. Problems may arise and if stacking technology does not meet the requirements.Also, when using poor-quality solution.

Determining the cause of possible localization issues:

  • crack in the bottom of the building indicate excessive pressure overlap;
  • upper part is damaged as a result of subsidence of the foundation base.

Before seal cracks in the brick wall is necessary to make sure that they do not increase in size.Otherwise, the work done will be fruitless.On the wall, attach targets of paper and trace their integrity.

To fix a small crack up to 5 mm wide, you can use the cement composition.Works are made in the following sequence:

  1. Originally from the slot you need to remove the debris and to treat it from the inside moist cloth.
  2. edges of the slit before work should knock down with a hammer, asthis will ensure a better adhesion of the mortar and bricks.Damage
  3. medium dimensions (from 5 mm to 10 mm) are also eliminated by means of cement composition, but with the addition of extra components - sand.

cracks that are wider than 10 mm, are critical in nature.The lack of timely intervention could have negative consequences.Fix such damage can be several ways:

  1. damaged area should be dismantled and replaced with new material.
  2. Masonry deals with the top row.Bricks are stacked according to the method "Stone Castle".
  3. In masonry reinforcement inserted fragments that span the crack.
  4. If you are unable to disassemble the clutch, the injury is sealed cement mortar.
  5. The gap can drive T-shaped metal elements which are fixed on both sides by means of dowels.The use of metal parts is not required.But in this case the wall of the building must be strengthened from within.
  6. Repairing cracks in walls of brick can be performed by foam or sealing means.The cavity gap must be filled with foam, wait until it hardens and crop material to a depth of 2 cm.
  7. The resulting space is filled with a cement mixture.When using sealant is important to choose the right makeup.It is not necessary to apply silicone sealant on the basis, as this material has no adhesion to the plaster, paint and putty.
  8. necessary to prepare a special sealer for the seams.It is placed in the gap by building gun.Sealant for cracks in the wall has a definite advantage over the cement mixture.He has the ability to increase and decrease in size without the formation of cracks, which is unusual for a conventional solution.This tool belongs to the category of expensive materials, but its use allows to obtain high quality results.
  9. cracked wall it is recommended to strengthen the inside.This procedure involves sealing the damaged area and the imposition of a metal profile, which will play the role of the castle.It should be positioned across the crack to prevent its further spread.Anchors are used for fixation of the element.You can use the steel bracket.In this case, you need to pre-drill the holes.
  10. If the cracks are formed as a result of incorrectly filled in a foundation base is recommended to install it on additional concrete belt.Along the perimeter of the house you need to prepare a trench depth of which should exceed the foundation depth.In this recess is placed concrete, from which the belt is being built.

How to remove cracks in the wall, covered with plaster mixture

danger of cracks in plaster walls is not limited to an aesthetic defect.Due to the damage it may suffer as a plaster coating and masonry.Mostly it refers to the outer walls where the trim is largely exposed to the negative effects of low temperature and moisture.Through a crack in the coating the moisture penetrates into the masonry, which subsequently freezes.This causes destruction of the backlog coverage and masonry.

These injuries plaster layer may be formed not only from the outside, but the inside of the house.This is a very thin cracks that are visually reminiscent of the web and distributed across the surface of the wall.The reason for this may be the wrong application of the composition, in violation of the proportions by mixing the components and failure to comply with requirements for coating treatments.You can select overlaying a thick layer of the solution among the most common mistakes.Cracks in this situation is a natural consequence of violations of technology.

lesions appear after finishing: wallpapering, painting or plastering.This can be prevented by using the reinforcing members, which are set before finishing.For this purpose, use several materials:

  • mortar;
  • fiberglass mesh;
  • fiberglass;
  • fiberglass.

The most convenient option is considered to be the last material.Fiberglass is attached to the primed and dry surface with a special adhesive designed for fixing stelooboev.After completion of the work, this material can be covered with putty or paint finish.

plaster mixture according to destination divided into 2 types:

  • for internal surfaces;
  • for exterior walls.

different data types of plaster components included in their composition.For exterior trim solution is prepared on the basis of cement, and for interior works are considered more suitable lime formulations.

To eliminate the cracks with plaster composition should be prepared:

  • capacity;
  • trowel;
  • floats of various sizes;
  • brush for plastering;
  • brush;
  • trowel;
  • water.

plasters can do on your own or buy ready-made.In the process of homemade necessary to monitor the consistency, becausetoo thin plaster will stay bad.The process of repairing cracks looks like this:

  1. With brush applied on the affected area, then leveled using a wooden float.
  2. If the plaster on the wall was applied by the rendering to the processed area is not different brush to dip into the water and on the surface to make Clap movement.
  3. easiest way to eliminate shrinkage microcracks.They need to be treated with deep impregnation which penetrates the coating structure and strengthens it.Then cracks can be filled dispersion paint.

solution for cracks in the wall, covered with plaster composition should contain fillers and binders.As this element can be used gypsum plaster, cement and building lime.The most durable is a cement-based material.Indicators of its strength can be determined by labeling, for the solutions used brand 400.

Building plaster will make the mixture more durable.This feature speeds up the setting of the compound.It has a distinctive feature - not shrink.Building lime used for exterior applications, because it dries the air only.

The cover up the cracks in the wall of plasterboard

Damage plasterboard material are formed due to several reasons:

  1. The most common technology is considered to be a violation of the installation frame and mounting plates.
  2. appearance of cracks can be triggered by wrong filler and jointing between sheets.
  3. The causes damage may also include sudden temperature changes in the room, an elevated level of humidity and contact with water.

Plasterboard not has good resistance to moisture.When interacting with the factor according to deform the sheets and retain a shape after drying.The only solution in this situation is the replacement of the material.Get rid of the cracks in the drywall can be in two ways.

  1. first option involves filling gaps or acrylic sealer.
  2. second way is adhered on top of the damaged section of glass fiber.Then, the surface should be putty, then you are ready to finish coating.

surface treatment process is as follows:

  1. Before you seal the crack in the wall of the house, using a putty composition, it is necessary to remove the damaged area a layer of plaster.
  2. further removed by a vacuum cleaner dust.
  3. Then you need to prepare the putty mixture in the following proportions: 2 parts powder to 1 part liquid.
  4. The resulting mass is applied in a layer 2 mm with a spatula.
  5. addition to crack process should be and the nearest station.
  6. When using reinforced tape it should be placed in the slot and cover the putty composition.
  7. putty dries for 1.5 hours.
  8. then it is recommended to clean and remove dust from the wall.

Sealing cracks in the concrete wall

main cause of defects in the wall of a concrete violation of the ratio of cement and water in the preparation of cement-concrete structure.In the process of laying its solution should be thoroughly compacted by vibrators.By cracking and failure to comply may result in withdrawal of the rules.Fresh concrete is recommended to cover with a cloth, to prevent excessive evaporation of moisture.

concern are cracks in the wall, which is in terms of frequent temperature changes.At low temperatures, the moisture gets into a crack cavity freezes and thereby increases the defect.Damage comes to fittings, it begins corrosive process, which affects the strength of the building.For early detection of defects in the construction must be regularly inspected.This will enable to carry out the removal of cracks in the walls at the initial stage of development.We can not ignore even minor changes in the defective concrete material.

So, for need:

  • hammer;
  • chisel;
  • grinder;
  • spatula;
  • metal brush;
  • brush;
  • vacuum cleaner;
  • rack of wood material;
  • trowel;
  • water, sand, cement;
  • adhesive;
  • a wire;
  • ironing board.

workflow takes place in the following sequence:

  1. Using a hammer and chisel, you need to embroider crack to a depth of 5 mm.This will help prevent the loss of repair structure.
  2. further damaged area is cleaned of dust and moistened.Use the sponge need to remove excess moisture.
  3. If you see the armature, it is necessary to treat the corrosion inhibitor.
  4. mixture is prepared on the basis of cement and sand, the ratio of 3: 1.The composition can be added PVA.
  5. If defects are deep, they should be completed in stages, wetting each layer of the repair mixture.If necessary
  6. crack reinforced with wire fragments.
  7. Then the surface must be leveled, for this use trowel.
  8. Once hardened structure protruding zone is adjusted by means of a grinder.
