Sealing tape: advantages and installation features

Kinds

Not all beginners know that when installing gypsum boards, in addition to profiles and other frame elements, they use tapes that improve the quality of finishing. Moreover, they come in several types:

Types of strips for gypsum boards

Sealing

Sealing or damping tape is usually made of foamed polyethylene or other porous material. Its back side is covered with an adhesive composition, onto which a protective strip is glued. In other words, this material is self-adhesive.

As a result, it is easily glued to the back of the profiles. In addition, the seal can be glued to the back of the hangers.

The photo shows a seal for profiles, which is a foamed self-adhesive strip

Purpose. So, we figured out what a sealing tape for a profile is, but why is it needed? Since the seal is located between the base (wall or ceiling) and the profile, it performs several quite important functions at once:

• Dampens vibrations. As a result, the likelihood of cracks appearing on the surface of the plasterboard is reduced;
• Dampenes impact noise. This property is especially important when covering interfloor ceilings with plasterboard;
• Elimination of irregularities. The sealant allows you to level out unevenness in walls and ceilings.

It must be said that the seal is not a mandatory element. Therefore, very often craftsmen assemble frames for drywall without it. However, as you can see, the use of this material is highly desirable.

The seal is easily glued to the back side of the profile

Apply. The seal is glued to all elements that are in contact with the base, i.e. on guide profiles and hangers. The process of installing it yourself is extremely simple - you just need to tear off the protective strip and press the material onto the surface of the profile. The latter must be clean.

The reinforcing strip allows you to avoid the appearance of putty cracks at the joints of gypsum boards

Reinforcing

Reinforcing tape for drywall is used when sealing seams. Its main task is to prevent cracking of the putty. Unlike all other tapes for gypsum boards, reinforcing ones can be called truly necessary.

It should be noted that there are several types of seam sealing strips:

• Paper. The main feature is that it is thin and has a uniform structure with the surface of the gypsum board. As a result, it is easily glued to the joint using putty. It must be said that the paper strip can be solid or perforated. Essentially, it doesn't matter what the surface is;

Serpyanka has high tensile strength

• Mesh. Mesh tape, or simply serpyanka, is made from fiberglass. An adhesive composition is applied to its back side, making the mesh self-adhesive. Another advantage of the material is its high tensile strength;
• Non-woven. Has the greatest strength. It is glued using the same principle as a paper strip. Since its thickness is greater, when finishing gypsum board, a thicker layer of putty is required.

Non-woven tape for drywall is highly resistant to various mechanical loads

Application. Instructions for sealing seams are as follows:

For separation

The dividing strip is designed to create a sliding joint between drywall and building elements (walls, ceilings, etc.). This allows you to avoid the appearance of cracks in the abutment areas and other surfaces of the plasterboard. The use of dividing strips is recommended in houses with large shrinkage.

The dividing strip is glued between the edge of the gypsum board and the structural element of the building

It must be said that in practice these bands are used very rarely. Therefore, they are quite difficult to find on sale.

Application: The dividing strip is self-adhesive. It is glued between the edge of the sheet and the main wall or ceiling, as shown in the diagram above.

Price. Dividing strips are produced by the Knauf company. The cost of one roll 60 mm wide and 50 m long is about 900 rubles.

Characteristics of soundproofing tape

To protect metal frames from noise, when constructing ceilings and walls, and laying floor coverings, damper tape is used. The rolled material is 30 m long, 10 cm wide and 3 mm thick. Surface density: 300 g/m2. The adhesive layer is applied to one or both sides of the tape.

The soundproofing gasket Vibrostek-M has the following characteristics:

• Correspondence between price and material efficiency.
• Reliable protection against structural noise, despite its small thickness.
• Long service life.
• Resistant to various intense loads.

Vibration-isolating tapes are in demand in the construction of residential buildings and office premises. With Vibrostek-M, rooms become more comfortable to stay in. The tapes are mounted between special materials. This ensures high-quality acoustics.

Tape sound insulation is not subject to deformation even under the influence of external factors and phenomena. The material has a number of characteristics:

• Zero water absorption.
• Resistant to oxidation, ultraviolet radiation, alkalis and weak acids.
• Elasticity and softness.
• Light weight (1 kg).

Vibroacoustic characteristics of the Vibrostek-M tape: dynamic modulus of elasticity 0.18 MPa at a load of 2 kPa; at 5 kPa - 0.35.

Characteristics

Soundproofing tape can be used for all types of sheets, as it has the following characteristics:

• Thanks to the closed cells, water absorption does not occur;
• It provides a high level of insulation against shock and noise, especially airborne and impact types;
• Resistant to oxidation;
• Not affected by fungus;
• Ensures the longest service life of the structure;
• Ultraviolet light has no effect on the tape;
• It tolerates contact with alkali or acids, but only weak ones;
• Perfectly withstands various atmospheric conditions;
• Easy to install due to the softness and elasticity of the material;
• The tape is very light, so handling is not difficult;
• Provides elasticity retention over a wide temperature range - from -80 to +100 °C;
• Environmentally friendly material. The tape contains no harmful or toxic substances, which allows it to be used without harm to health;
• Impact noise absorption limit up to 28 dB.

A large number of advantages during use have determined the popularity of the product, since at a relatively low cost it is possible to increase the quality of insulation by 20-40%, depending on the professionalism of the master.

When choosing a material, you should pay attention to the following basic indicators:

• Temperature range;
• What is the coefficient of vapor permeability;
• Thermal conductivity level;
• Material density;

• Flammability of the tape, it is desirable that combustion does not occur at all. When using special additives, the material will only melt;
• In some cases, color matters if the tape is to be visible;
• Tensile strength – the minimum value should be 0.035 MPa;
• In terms of elasticity under a load of 2 MPa, the indicator should be 0.23 MPa.

Due to its resistance to aggressive environments, the seal partially prevents harmful substances from entering the material. Because of this, the durability of the entire structure increases.

Possible applications of Vibrostek-M

Soundproofing tape is used as a cushioning material when installing:

• ZIPS panel system in building structures.
• Wooden floors and floors.
• Frame soundproofing cladding and partitions.

When installing sandwich panels, the tape is laid in two layers at the points of contact with the ceiling and side walls, at points of support on the floor. When installing frame partitions, sound insulation is placed between the fastening elements and load-bearing building structures, at the junction of the partition sheathing sheets.

Vibrostek-M is used when arranging wooden floors. The material is placed under the joists and floor beams - at the points of their support on the walls. The width of the tape should be more than 10mm on each side of the beam or joist. The vibration stack is also laid on the ends of the beams that rest on the walls.

The soundproofing gasket Vibrostek-M is indispensable:

• When assembling various sound insulation systems (with and without frame).
• In cladding and wall structures.
• When installing suspended ceilings.

The tape is used as a border layer in the manufacture of a floating floor.

Sealing tape

Sealing substrates are made of elastic polyethylene foam. These are cellular strips covered with a self-adhesive layer on one side. They are protected by special paper, which is peeled off before use. The form of release of sealing strips is rolls of various lengths.

The material differs in brand, length and thickness of polyethylene foam. There are 3 varieties:

• Uncrosslinked gas-filled.
• Chemically cross-linked.
• Physically stitched.

The width of the tape varies from 30 to 90mm. Common thickness is 30mm.

Sealing gaskets ensure a tight joint between the metal profile for plasterboard, as well as load-bearing structures - walls and floors. The tape is used not only for sealing, but also for vibration reduction and sound insulation.

Reference. A plasterboard partition made of sealing gaskets will serve not only as protection from noise, but also as a screen, attracting and amplifying vibrations and sounds from neighboring rooms.

The material is glued onto guides through which sounds pass from one room to another. Rack profiles fixed to the walls are also covered with insulating tape.

Reinforcing tape

Reinforcing tape is indispensable when performing various construction works - repairing walls and ceilings, preventing the formation of cracks at the joints of plasterboard slabs, shedding, swelling, peeling of the cladding. The structure of the tape contains intertwined fibers of strong material. The products are produced in reels, 50-100 meters long. Regular and self-adhesive material is available for sale.

Self-adhesive tape serves as an excellent electrical insulating material. It is used for waterproofing pipes and caulking joints. Serpyanka is intended for reinforcing seams when performing finishing work.

Ordinary paper tape is used to seal simple seams. Compared to serpyanka, paper reinforcement tape has significant advantages:

• An excellent combination with drywall and putty.
• Possibility of use when strengthening the prepared surface due to its minimal thickness.
• Reasonable price.

The reinforcing tape is attached using putty or gypsum plaster. Fabric and paper are characterized by good moisture absorption. PVC tape is moisture resistant.

Important! When covering drywall, the use of reinforcing tape is mandatory. This will ensure the strength of the structure and protect it from external influences.

Separating sealing tape is used in houses subject to severe shrinkage. The material plays a primary role in sealing the joints of plasterboard sheets. During construction and repair work, dividing tape is a component material for gypsum boards along with jumpers, profiles, screws, etc.

A tape separation gasket is required to perform a number of jobs:

• Metal profile fastenings.
• Tightly seal seams between sheets.
• Fixing mounted partitions to ceilings and load-bearing walls.

The dividing tape is produced in rolls, the thickness of which is from 2 to 4 mm, the length is from 30 m.

For effective sound insulation, Vibrostek-M materials are used. Due to the elastic properties of fiberglass and air pores, vibration isolation tape has unique damping characteristics.

Sealing tape for drywall profiles is a special material used when creating a metal frame for drywall, as well as when sealing gypsum board joints. It has its own varieties and distinctive properties.

Sealing damper tape is a sound insulator and vibration absorber

What it is

To increase the stability of the structure, no matter whether it has a frame or not, you must follow the installation rules.

An important condition for high-quality sound absorption is the integrity and solidity of the structure, as well as the quality of installation.

Any sounds, shocks, vibrations and noises provoke vibration of the panel, and as a result, the material generates secondary noise and the effect of using insulation is minimized. In some developed countries, such tape is a mandatory condition for construction; work cannot be performed without the use of soundproofing tape.

At the same time, the insulation provides a more durable fastening of the panels with the profile. The sealant is also extremely important in the presence of any joints where the insulating material is subject to bending or deformation, for example, at the transition between the ceiling, walls and floor. Even minor cracks provoke the penetration of sound in large quantities and the efficiency of the entire structure is significantly reduced.

Typically, a layer of sealant is placed on metal or wooden guides. They are then connected to the sheet of the selected material itself.

Soundproofing tape comes in 4 different types:

• UW100/CW100 - width is 9 cm;
• UW75/CW75 - width 7 cm;
• UW50/CW50 - width 5 cm;
• UD27 - width 3 cm.

The tape is made from isolon, a subtype of polyethylene foam. They have a cell structure, but their structure is closed. The tape is rolled up. The thickness of the insulation comes in different widths, but is mostly 30 m long. Adhesive is applied to both sides, so the tape easily clings to both the supporting structure and the panel.

The most technologically advanced and highest quality tape is considered to be the “Dichtungsband” type.

One of the manufacturers of such a seal is. Alternative options that also

foam rubber and polyurethane foam types have good characteristics. The density of such materials reaches 150 kg/m, which corresponds to TU 38.106569.

The selection of the appropriate seal width should be based on the weight of the structure. The heavier the panels are attached and the thicker their layer, the wider the tape should be selected. Since the space for connection to the profile and material increases, the strength of the connection also increases significantly.

The choice of tape should be given to world leaders in the industry who have extensive experience in the production of sealing materials. Today the following manufacturers are represented on the market: Knauf, Vibrofix, XC Alenor, Vibrosil.

Characteristics of sealing damper tape

This type is made from polyethylene foam material. On one side there is a sticky layer for gluing. It is easily applied to metal elements used to create a frame for drywall and is firmly fixed. This tape has advantages:

Damper sealing tape for metal profiles under plasterboard

1. is a noise absorber;
2. When using tape during installation, the metal profile does not come into contact with the concrete base, which prevents the occurrence of condensation and oxidation;
3. absorption of vibration arising from neighbors above or from construction (other) work on the street.

If vibration of structures occurs, the use of the material prevents cracks from appearing on the drywall.

Sealant is not always used when working with drywall, but it is advisable to use it.

Application

By following the correct technology for using a damper seal in repair work, it will create additional protection for the plasterboard structure from harmful influences.

The sealing material should be glued to the side of the mounted profiles to the rough surface. For convenience, you should have a cutting knife on hand. Since the tape has a layer of glue, it is quite easy to fix it on the profile.

The cost on the construction market ranges from 157 rubles. up to 400 rub. per roll.

Types of sealing tape

There are a large number of sealing agents on the construction market, which differ in their structure and purpose. Almost all types of tape have the only common property - on one side there is an adhesive layer designed to fix the material to the base. This layer of adhesive is protected by paper, which must be removed before use.

The tape and its application can be divided into:

• for rough finishing - damper;

• for sealing joints between plasterboard sheets - reinforcing;

  
  Knauf Kurt tape has distinctive dimensions and is applicable on large plasterboard surfaces

• for separation - sliding joints.

The tape is intended for the joint in the corner of the gypsum plasterboard and the load-bearing wall, which is going through the shrinkage stage

Before you start decorating your apartment or office, you need to figure out where and which types of drywall sealants are used.

Characteristics of reinforcing tape

Reinforcing tape is a specially created material for strengthening drywall joints. It performs the important function of fastening gypsum board joints, which gives a durable structure. Subsequently, there are no cracks or deformations of the ceiling or plasterboard walls. There are several types of reinforced tape:

• Serpyanka is a self-adhesive reinforcing tape with a composition similar to a synthetic bandage. Used to seal joints in plasterboard sheets;

  
  Serpyanka is available in various sizes for plasterboard joints

• perforated paper - used manufactured by KNAUF, distinguished by its strength and quality of functions. Thanks to the perforation, the tape does not gather like an accordion during installation, air bubbles do not collect under it, and has excellent air-permeability properties, which is important for a plasterboard product;

  
  Knauf paper tape is a durable material for reinforcing drywall joints

• bandage - is a durable fiberglass material made from non-woven fabric. It is attached with a “raw” putty solution to the joints. Has the same properties as serpyanka.

Non-woven sealing tape for reinforcing drywall joints will create the strength of the entire structure due to its composition

The use of reinforcing tape is mandatory when finishing drywall, since it strengthens the created structure and prevents further impacts on the structure.

The installation of reinforcing material is required depending on its type. Self-adhesive is applied and fixed easier than paper or non-woven tape.

Watch the video: laying reinforcing tape at a gypsum board joint.

Installation of KNAUF paper is carried out in stages:

1. preparation of joints - it is required that the plasterboard joints have a chamfer. If it is not there, then you should use a construction knife to carefully make cuts on the edges of the drywall at 45 degrees, 5 mm deep;
2. chamfered joints should be cleaned of dust and plaster stones;
3. Using a brush, cover the seam well and thoroughly with the primer mixture. Let dry;
4. after this, the Knauf Uniflot putty solution is diluted (considered by the masters to be one of the best mixtures), according to the table on the bag;
5. Cover the seam with a thin layer of putty. A paper tape is applied evenly to the wet putty and pressed with a spatula so that the edges are firmly fixed in the putty. Excess solution comes out and remains on the spatula. They can be used to seal fasteners.

6. After drying, the tape should be covered with a second layer of putty. When dry, remove all excess pieces from the finished joint with sandpaper.

The cheapest of this series is the serpyanka - the price is 50 rubles, the most expensive - the Knauf non-woven one costs 190 rubles. Paper tape can be bought for 70 and 95 rubles.

Separator tape

The separation seal creates a sliding joint between the gypsum board and parts of the building, so that cracks do not appear at the points of contact with another surface. Used in those houses where there is a lot of shrinkage. During shrinkage, the biggest problem is the appearance of cracks. The tape prevents this from happening.
