How to close up interpanel seams in panel houses from the inside and outside with your own hands: Technology - SNIP and Step by step + Video In many panel houses, the seams begin to deteriorate over time. Temperature drops, precipitation and strong winds only accelerate this process.

In order to avoid freezing of the wall, timely sealing of interpanel seams with special sealing agents is necessary. In case of deeper damage to the seam, a major overhaul of the panel joints is required.

Reasons for the destruction of panel joints and seams

How to close up interpanel seams in panel houses from the inside and outside with your own hands: Technology - SNIP and Step by step + Video In panel houses, during major repairs, they are engaged not only in the roof, but also in the sealing of interpanel seams.

Their sealing is an important technological process.

Over time, joints and seams in panel houses can begin to deteriorate, resulting in the formation of mold and mildew.

The walls begin to freeze and the apartment gets cold. To avoid this, and it is necessary to seal the seams.

Depressurization of interpanel joints of seams occurs for the following reasons:

  1. gross violation of norms during construction;
  2. due to uneven settlement of the building, slab can shift, forming cracks and cracks in the seams;
  3. destruction of panels due to temperature differences;
  4. external atmospheric influence on the joints in the form of rain, snow and wind.

Materials for sealing interpanel seams

How to close up interpanel seams in panel houses from the inside and outside with your own hands: Technology - SNIP and Step by step + Video The interpanel seam is insulated with self-adhesive tape and mastic. According to their characteristics and field of application, these materials can be divided into different brands.

The base for the mastic and the tape is a special sealant, which retains heat and protects the joints of the board.

The best composition of the sealant is foamed polyurethane. It does an excellent job of protecting seams from mold and mildew.

After all, it is because of these harmful factors that the seams are destroyed, and as a result, the walls freeze through in winter.

Types of sealing of joints

There are several types of sealing of interpanel joints in panel houses:

  • primary - is carried out at the stage of delivery of a new house, when there was no treatment with polyurethane sealant yet;
  • secondary - this is already a direct repair of the joints of an already residential building

Let's consider these types in more detail.

Primary sealing of seams

Carry out immediately after the completion of the construction of a new house.

Seams of new buildings are processed in three stages:

  1. How to close up interpanel seams in panel houses from the inside and outside with your own hands: Technology - SNIP and Step by step + Video interpanel the seams are filled with special polyurethane foam;
  2. followed by a layer of insulation;
  3. they seal the seam from the outside with mastic with a water-repellent effect.

The result is a warm seam, that is, not only heat-insulating, but also waterproof.

Secondary sealing of seams

It is carried out 5 years after the house was commissioned.

Sealing is carried out over the old layer with a new layer of sealant.

How to close up interpanel seams in panel houses from the inside and outside with your own hands: Technology - SNIP and Step by step + Video The level of secondary processing will depend on the state of the interpanel seam. For example, in case of a minor violation, it will be enough to apply one layer of mastic.

In case of deeper cracking with damage to the insulation, it will be necessary to clean the entire seam from old materials.

After that, a full-fledged joint is required as with the first sealing.

The rules for sealing seams are as follows:

  • if leakage of joints is found on the end side of a panel house, then it is necessary to seal the seams along the entire front side of the building and its joints with the longitudinal wall;
  • when the longitudinal joints flow, all joints must be sealed along the entire height. And along the leaks, it is necessary to process horizontal joints;
  • cracks in horizontal joints of panels are processed with the capture of three adjacent interpanel seams;

When carrying out repairs, the sealant in the seams is subjected to compression and tension. Therefore, the sealing layer must be made half the size of the joint between the plates.

Requirements for sealing interpanel seams

Seams in panel houses must be properly sealed to avoid cracking in the future.

Therefore, when repairing interpanel joints, high-quality preliminary work with the seam is needed.

Below we will consider in detail the repair of the seam with its cleaning and preparation:

  • the first stage is the preparation of the seam, that is, they clean the joint of the panels from dust, paint and dirt. Remove old materials from the seam and make jointing;
  • at the second stage, fill the seams with polyurethane.

Polyurethane foam for filling interpanel joints expands during application, so do not foam the seam too abundantly.

The seams of a panel house can be cleaned manually or mechanically.

Before starting work, be sure to visually inspect all the joints of the panels. They must be dry and intact.

  • the penultimate stage is the seam insulation with a special material that is produced in the form of tubes. This insulation has high elastic properties and a dense structure. It is easy to work with such material and easy to install.

    It should be laid on a layer of not yet frozen foam.

The diameter of the insulation should be 30% greater than the seam width.

The insulation tube is placed in the seam without rupture so that there is room for sealing the seam with mastic.

  • the final stage includes sealing the joints with mastic.

Note also that the seams must be sealed in dry, clear weather at a certain temperature regime, from -10C to + 30C.

Sealing at the level of the second floor and above is performed only by specialists who have passed mountaineering training.
