How to seal the joints between the panels on the ceiling

Such troubles as formation of cracks between the floor slabs on the ceiling, or simply a manifestation once not entirely successful embedded seams, are very common in prefabricated high-rise buildings.Therefore, at the first sign of these phenomena need to take action.But this requires to have information as to close up the seams between the panels on the ceiling alone, without recourse to a call-dressers professionals.

If there was a small crack between the plates, it is necessary to start with its expansion.Very often it happens that the process of cutting, even small cracks or crevices suddenly opens up "great horizon" of the work.Therefore , once got his hands before the repair activities, it is necessary to make immediately to the conscience, in full amount to more to this question does not come back for a long time.

If you wish to solve two problems - sealing seam and the alignment of the ceiling, the entire seam of the old concrete should be cleaned.Usually, it is not difficult to make, since the construction of houses, used for jointing too durable cement.

Materials and tools

order not to repeat the mistakes of craftsmen who worked in the construction of the house on ceilings without seams due diligence, you need to buy quality materials and all the necessary tools to work.To be not just cover up and carefully embroider seam and carefully sealed it when terminating.

So starting work you need to buy:

1. From the tools required medium, wide and narrow trowel, spray, brush narrow steel, wide paintbrush, a mixing solution, building a knife and a hammer drill.

2. You can close up the gap, using different materials and is to list all that can be useful.

  • primer for concrete deep penetration - need for better adhesion and surface material, which will be stopped junction between the slabs.

  • Cement NC , which is designed to seal deep joints.This material tends to expand during solidification, tightly filling the entire space of seams and joints.

  • Upon detection of a wide seam that requires termination, you must purchase a dense insulation material made of polyurethane or foamed polyethylene .foam can be used instead of them.
  • take a latex elastic putty .
  • needed reinforcing mesh-serpyanka.Width it will depend on the width of the joint - tape should extend beyond its borders by 40 ÷ 50 mm on both sides.
  • for finishing require primary and finishing putty for the entire ceiling area.

How to seal the joints between the panels on the ceiling - do yourself

Remo nt Swiss s between the floor slabs necessarily drags along bringing entire ceiling in order, so you should start with a complete cleansing of the surface of the paint, whitewash andmay plaster.

  • ceiling with the spray sprayed with water.It is better to carry out spraying is not just the ceiling once, and parts.Good wetted portion is left for 10 ÷ 15 minutes to impregnate and then remove the old coating with a wide spatula and medium.You can then proceed to the next area, where you want to spend the whole procedure from the beginning.Such work is carried out to complete cleansing of the entire ceiling.
  • SAEs in to behold the old coating, once the owner sees volume of forthcoming works.Usually one has to room two or three joint slabs.Sometimes they are embedded very messy and ugly act humps.These bulges and eliminate the need to make a perfectly smooth ceiling.

To do this, take a hammer, install it at the desired attachment, switch the percussion mode without rotation, and step by step to liberate the junction of the old frozen solution.

The joints must be carefully made

joints must be carefully butchered

joints and around the stove should be thoroughly cleaned, and the gap itself is recessed not less than 50 mm.

  • Next need to take a narrow iron brush or wide brush and thoroughly clean the slot from dust and small pieces of concrete.

  • next step - the gap primer treatment in several layers , each of which must be dry.The primer will make stronger the remaining frozen in the joint solution will not let it form in dampness and fungus, will provide a good contact with the repair composition that will be applied later.
  • If the gap between the joints sufficiently wide and is more than 30 ÷ 35 mm, means you must first fill it with foam.It is well-entrenched in the primed surface and expands and fills the opening .

Congealing, foam comes out of the seam, and when it is completely dry, its carefully cut so that in the joint plates in the foam turned groove , depth 30 ÷ 50 mm, tapering inside , ontriangle type.

  • if detected at the junction deep cleaning, but at the same time narrow, you should proceed as follows.

selecting seal of polyethylene foam desired thickness, it one hand coated strip and sealant is charged into the cleaned and primed the joint with a spatula, leaving room to fill with concrete.

  • Next, joint solution is embedded expanding concrete, but it is necessary to leave a small depression in junction to expand the solution and plaster.

  • After drying the solution or preparation in dry mounting groove the foam is applied to the junction of elastic putty Latex.The work is best done using two spatula - wide and narrow or medium.On gaining a spatula solution of capacity and narrow it is applied to the joint between the plates, in the sealing seam and leveling to level the surface of the ceiling, while removing any excess putty.

Closing holes in the ceiling

Sometimes it happens and so that opens not just narrow slit, and a large hole at the weld clean-up of the old solution- DEF kt Square Ita overlap.In this case, the hole can be repaired in two ways.

Sometimes the ceiling while cutting sutures may appear and a "surprise»

Anyway , the first thing to do - it thoroughly clean the inside of the hole formed.This process is best done using a narrow brush .

1. Freeing of dirt inside of the hole, its need a good spray primer.After waiting for when it is dry first layer, apply the second.

  • Further, the hole is filled with foam.
  • Then, it after drying and expansion, excess cut off, and the inside taper hole is cut at the base of the size of the hole, and a height of 40 ÷ 50 mm.
  • This cut is needed to secure it in cement mortar, which is applied in the following stage.He leveled a spatula and allowed to complete drying.
  • then to the place where there was a hole and around 50 ÷ 70 mm is applied putty, and it glued mesh-serpyanka, which is pressed into caused layer of mortar, smoothed and allowed to dry.
  • Next work is the same as when grouting.

2. Another way to seal different from the first, and it is applied in the case was found in the ceiling of large void.

  • In this case, the required piece of plywood (you can use scraps laminate) measuring approximately 100 mm longer than the hole size.
  • then, needs to be strengthened in an aperture grille wire that needs to be secured to the sealer or grout inside holes.After drying, the solution needs to be wire firmly secured within the opening . Grille will serve as reinforcement for repair mortar, with which they create a kind of plate.

  • plywood laid on the prepared concrete mixed solution, it should be uniform and not too thick.
  • plywood platform with a solution raised and tightly pressed to the hole, so that the solution is completely filled the rest of the cavity. Have come up with for this kind of formwork reliable backup, which will hold its to dry completely repair structure.For this approach thick branch block or pyramid from a table and chairs.
  • After drying solution opening get perfectly smooth surface of the ceiling.
  • Then you can begin to work on putting in order the entire surface of the ceiling.
