Types of materials for sealing seams in panel houses: mastic, sealant, polyurethane foam and others

In panel houses, seam sealing is crucial to preserving the comfort and longevity of the structure. Air leaks, water intrusion, and energy loss are all avoided by properly sealed seams, making a home more comfortable and energy-efficient. To accomplish this, a variety of materials with distinct qualities and uses have been developed over time.

Polyurethane foam, mastic, and sealant are some of the most often utilized materials for this application. Mastic is a versatile option because of its flexibility and ability to stick to different surfaces. There are various types of sealants that offer resilience to weathering and durability, such as silicone and acrylic. Conversely, when polyurethane foam is applied, it expands to fill in spaces and offer superior insulation.

Apart from the materials that are frequently utilized, other alternatives such as epoxy resins and butyl rubber can also be employed, contingent on the particular demands of the undertaking. Every material has benefits and best practices, so it’s important to select the appropriate one for the task. Comprehending the attributes of these substances can facilitate well-informed decision-making and guarantee the durability and effectiveness of your panel house.

What can you use to cover cracks and joints??

It is best to leave the selection of panel wall materials to the experts. Every kind of slab has a unique sealant.

For example, pre-made sealant compositions (acrylic, polyurethane) work flawlessly with sandwich panels and SIP.

Strong Portland cement grades (M500 and above) are used to make cement mortar, which is used to seal monolithic slabs. Bitumen mastic is applied in a second layer to add extra waterproofing.

Additionally, special construction cords with a polyethylene base are laid; these are regarded as insulation materials, and are used for sealing joints together with compounds in cracks prepared by cleaning, priming, and degreasing.

Thermal insulation tapes, which are pictured as cords and tubes, prevent cold bridges, reinforce the space between tiles, and keep mastic and other mixtures in the seams.

Anchor materials are best bought from reputable manufacturers online or in specialty stores.

The products need to:

  • have a manufacturing date;
  • set time and storage conditions;
  • quality certificate;
  • trademark for the nomenclature of the Russian Federation;
  • Instructions for use and guarantee.

A thorough description and the substance’s composition must be listed on the package. It is recommended that the industrial product be packaged hermetically.

On the construction market, a wide variety of means are available. The most widely used are mounting foam, silicone compositions, and mastic. All of these monies are carefully mixed with any materials and chosen based on how wide the seams are.

For instance, expanding compositions work best for wide seams, and installation foam works better in deep recesses. However, for some panel types, the composition is occasionally chosen on an individual basis.

The plasticity of the material is taken into consideration when selecting the one required for sealing. One of the primary qualitative traits that enables the material to fill in the superficial pores and disperse uniformly along the gap is this one.

Types of putties for sealing outside and inside

Large Particular attention is given to external putty during construction because its performance is contingent upon its state:

  1. microclimate and heat preservation in the room;
  2. resistance of slabs to unexpected seismic events;
  3. no deformation of load-bearing walls and protection from water, insects, temperature changes.

In apartment buildings, they employ:

  • cement mortar;
  • mastic;
  • sealants;
  • polyurethane foam used simultaneously with the sealant.

The material used for each type of mortgage must be multiple times larger than the slot space, but it cannot go past the wall structure. As a result, it is spread out evenly and trimmed using a spatula. A construction knife is used to trim the polyurethane foam’s frozen, expanded remnants.

Mastic

This kind of material is a viscous plastic mass made mostly of natural materials with additional fillers like rubber, plasticizers, tar, etc.

The industrial product comes in a few different forms; it can have one or two components. The mastic’s polymer base exhibits adequate elasticity and good adherence to a variety of surfaces.

The following businesses are thought to be the most well-known producers of the material:

  • CJSC "RASTRO" (St. Petersburg);
  • LLC TPK "MasticIzol" (Moscow);
  • "Latest Technologies" (Novosibirsk).

The material is good to work with and has a long shelf life of up to 15 years. Mastic can be polyurethane or bitumen.

It was classified as rapidly hardening or non-hardening (for lubricating door and window openings and mechanisms) based on the quality of solidification.

For seams, fast-hardening mastic is a better option. The product’s ability to repel water is one of its key characteristics.

Every type is further separated into subtypes. Popular bitumen mastic, for instance, is separated into rubber, polymer, emulsion, and purely basic varieties. Additionally, there is heated mastic that is both warm and cold when applied. Compared to bitumen, the polyurethane variety is produced with a lighter color.

After the surface has been thoroughly cleaned and the seam has been treated with a primer solution and fungicidal additives, apply mastic. In addition, the mastic composition is applied last in a complex of layers for sealing, hardening and offering water resistance.

Sealant

The material is produced in hermetically sealed packaging as a ready-made composition and can be:

  1. one-component;
  2. two-component.

Different kinds of sealants work particularly well for expansion joints and as one of the layers in the "Warm Seam" method, which uses acrylic and polyurethane components as its technology.

Sealants are available in two convenient forms: cylinders that hold a specific amount of product or "pistols" that have a cone-shaped nozzle for applying product. However, they can also be purchased in 1-2 kg buckets, from which they can be removed using a spatula and applied using a brush.

The material’s benefits are taken into account:

  1. UV resistance.
  2. Structural integrity that lasts for a long time.
  3. High elasticity, compression and strength.
  4. Chemical resistance.
  5. Compatible with any surface.
  6. Quick drying after application.
  7. Good gap filling.
  8. Long lasting functionality and maintainability.

Although they fall into various categories, sealants are highly common.

  1. silicone;
  2. acrylic;
  3. polyurethane;
  4. polymer products.

While the color and transparency of certain materials may vary from those of others, all materials share certain common characteristics.

The top manufacturers of sealants are thought to be the following businesses:

  • Stayer Master;
  • TYTAN Professional;
  • BISON.

Interpanel seams both inside and outside the building are sealed with sealants. Even for a novice, they are simple to work with.

The application surface is first cleaned and degreased before, if desired, insulating tape is inserted into the seam to seal it. Sandwich and SIP panels work particularly well with sealants.

Tubular seal

Although polyethylene is also used, polyurethane foam is the most common material used to make this material. Vilaterm is regarded as one of the most widely used seam heat insulators because it consistently obstructs the passage of cold air.

Various companies produce the quality composition of the brand:

  • VILATERM (Moscow);
  • Plant "Stroydetal" (Moscow);
  • LLC "Unified Center for Waterproofing Materials" (Moscow).

Tubes and cord are used to symbolize the seal. The tubes’ (cords’) diameter increases from 6 to 8 (mm) to 30 to 40 to 50 to 80 (mm).

Depending on the depth of the tile-to-tile gap, this variety lets you select the best kind of insulation. Tubes can have holes in them or be solid. This makes them easier to work with and helps them to wrinkle nicely when you lay them (especially if the product has holes).

After the gap is ready, the tubular sealant is inserted and filled with any sealant that is applied. It comes in skeins, is lightweight, easy to work with, and cuts nicely with a construction knife.

Preliminary calculations of all horizontal and vertical seams that will be sealed either primary or secondary form the basis for material purchase.

Polyurethane foam

Seams ranging in width from 1 to 8 (cm) can be sealed with this kind of product. It can be applied alone, in conjunction with insulation, and in addition to other compounds, particularly when creating a "warm seam."

Foam offers a lot of benefits.

  1. she is easy to work with;
  2. it is conveniently packaged in cylinders;
  3. has persistent adhesive qualities to the environment.

Furthermore, the product deeply penetrates the joint’s pores and hardens rapidly.

Once the foam has been applied, allowed to expand, and solidified, any uneven remnants are removed using a construction knife.

However, for some varieties, this is not necessary because the superior composition consistently seals the panel seams.

The top foam producers are taken into account:

The ability to work with polyurethane foam at low temperatures is one of its key characteristics. We refer to them as frost-resistant.

Other varieties of polyurethane foams are taken into consideration:

  1. waterproof;
  2. polyurethane, which are divided by type into one-component and two-component.

There are various volume options for the product. The most common capacities are 870 and 750 ml.

Warm seam

Because it uses three components and goes through multiple stages, this kind of technology is regarded as complex. The most dependable method of sealing the space between tiles is called a warm seam, and it is applied after the gap has been cleaned, primed, and degreased. The insulation is applied in the form of tape.

This kind of material is referred to as a sealant and is covered in mastic and polyurethane foam, with a cement base underneath. It is best to leave the choice of materials for caulking the space between the slabs to experts.

They will choose the mastic, insulating tape, foam type, and Portland cement brand that are appropriate for the particular kind of panels based on the panel types as well as the depth and width of the seam.

  16. LLC "Unified Center for Waterproofing Materials" (Moscow) – 25.

The cost of building materials is a dynamic market that is influenced by numerous economic factors and available supply. Purchasing material is most costly in the Moscow Region and St. Petersburg; it is less expensive in the Russian Federation’s central region (the Vologda and Bryansk regions).

Mastic Thick, sticky substance applied to seal gaps and joints.
Sealant Elastic material used to fill and seal gaps, often in a flexible tube for easy application.
Polyurethane foam Expanding foam that fills gaps and hardens, providing insulation and sealing against moisture and air.

Selecting appropriate materials for panel house seam sealing is essential to preserving longevity and energy efficiency. Various types of materials, such as polyurethane foam, sealant, and mastic, have different benefits based on the particular requirements of your building or remodeling project.

Mastic is a flexible option that sticks well to a variety of surfaces and is long-lasting. It’s frequently used around windows and doors, for example, where flexibility and weather resistance are crucial. For panel houses to remain structurally sound over time, mastic must seal well to help stop water intrusion and air leaks.

On the other hand, when sealants are applied to joints and gaps, they create a flexible and waterproof seal. They are available in different formulations appropriate for varying substrates and environmental circumstances. For instance, silicone-based sealants are perfect for outdoor applications where exposure to sunlight and weathering is a concern because of their exceptional flexibility and UV resistance.

Expandable polyurethane foam fills voids, offers insulation, and adheres firmly to surfaces, making it a valuable material. Larger voids and irregular shapes benefit most from its use, as it ensures a complete seal that lowers heat loss to improve energy efficiency. Additionally helping to insulate against sound, polyurethane foam is advantageous in settings where noise pollution is a concern.

Take into account various factors like the project’s requirements, building materials, and climate when choosing materials for panel house seam sealing. Every material has distinct qualities that can have a big impact on the functionality and longevity of your building or remodeling projects, whether it’s mastic, sealant, polyurethane foam, or substitutes like acrylic-based goods.

There are a variety of materials available to homeowners and builders for panel house seam sealing, each with specific benefits. Among the most widely used materials are mastic, sealant, and polyurethane foam; they provide efficient solutions for various seam types and environmental circumstances. Making the best decision to guarantee a long-lasting and weather-resistant seal in panel houses can be aided by having a thorough understanding of the characteristics, advantages, and suitable uses of these materials.
