The question often arises, how are the seams in the drywall structure reinforced? There are various types of reinforcing tapes for gypsum board joints. Each tape performs specific functions and has its own degree of reliability. Let's figure out the best way to use a serpyanka or Kurt paper tape from Knauf. We will find out what the tape with metal inserts is for and how to mount it. On the selected video, you can see the subtleties and nuances that are important to observe in the process of working with putty joints on gypsum board.

Reinforcing tape application

When doing repair work in an apartment, sooner or later every master or owner is faced with the use of drywall, and you also need a tape for gypsum fiber board for seams and abutments. This building material is unique because it is widely used:

• for leveling walls and ceilings;
• creation of multilevel ceilings;
• the creation of arches, partitions, bar counters;
• creation of a fireplace, niche, box;
• production of furniture items.

Drywall has a perfectly flat surface, which is practical for finishing work. But, in order to start painting or gluing wallpaper, drywall should be sealed.

GVL tape is used to close the joints of plasterboard sheets. At the border of the 2 sheets, there is a small depression resulting from a pre-made chamfer. This cavity should be sealed with reinforced tape. It performs the functions:

1. The joint is strengthened. During long-term operation, drywall does not deform or crack. This is mainly due to temperature differences. Even if the temperature does not jump much - only 5 degrees, the plasterboard surface is susceptible to this.
2. Brings out the plasterboard surface to a perfectly flat surface.
3. If the gypsum board picks up moisture, it will expand, after drying it will decrease. Reinforced drywall tape maintains the integrity of the entire coating. Changes in moisture can be in private houses, when it is spring or autumn outside, the house also becomes damp. GCR absorbs moisture. When the temperature rises, the surface dries out.
4. Reinforced tape with a metal strip insert for plasterboard corners. It protects the corners from cracks and mechanical stress.

To seal large cracks on the surface, use the Kurt tape under the drywall. It is wider in size and, accordingly, has a higher percentage of strength. Kurt plasterboard reinforcement tape is also produced for reinforcing large joints.

Without the use of tape, the plasterboard construction will last a short time. As a result, deformation will occur, the surface will be covered with cracks.

Types of tape for GVL

Build the market offers a variety of materials to create the strength of plasterboard structures. Before purchasing drywall tape, you should familiarize yourself with its application, as well as the manufacturer.

There are different types of reinforcing tape for drywall:

1. Serpyanka. One of the simplest and most common tapes for gypsum board. It is easy to install and practical to use. Appearance - mesh. Cost - 65 rubles 1 roll.

   

2. Paper is the discoverer. It was she who first appeared on the construction market. Its main feature is that it does not tear when wet. Another big plus in such a tape is that the paper does not stretch during installation. Since it is thin, the plasterboard surface practically does not need to be leveled after installing the paper tape. The cost of the tape is 25 rubles per roll.

   

3. Metal inserts in drywall tape. Such a tape is used not only on the outer corners of the drywall structure, but also on the inner corners, which also need to be reinforced for the strength of the structure.

   

4. Damper tape. It is also a drywall tape. The tape differs from others - it is made of polyurethane foam. This tape is mainly used as a seal. Since the tape has a layer of applied glue, there are no difficulties in gluing.

   

It is worth noting that Knauf drywall paper tape has special, small holes for letting in air, which can get under the paper during application to the surface.

With the use of reinforced tape, the plasterboard surface or product has a fairly long shelf life - 10 years.

Drywall mortar

The correct mix must be selected to reinforce the joint. The material used must be gypsum-based and have good adhesion.

Knauf Fugen - putty made by specialists for sealing joints between gypsum plasterboards. But, sometimes it is used as an adhesive.

Knauf Uniflot is a durable water resistant mixture. After drying, this putty does not absorb moisture, therefore it is intended for rooms with high humidity. No reinforcing tape is needed when using putty. And also the mixture is used to seal cracks on a plasterboard surface.

Semin CE78 - "New Formula" is intended for sealing joints in plasterboard structures. It has sufficient strength, does not crack after drying, reinforces joints well.

JS weber vetonit is a polymer putty for sealing drywall joints. The maximum thickness of the applied putty is up to 5mm.

Volma Seam is a non-shrinking putty mixture intended for reinforcing joints and correcting defects on drywall. The thickness of the applied putty is up to 5mm.

Serpyanka

Serpyanka goes on sale in rolls. This is a sticky bandage. The tape is made of threads using glass, which gives it strength and practicality. Knauf drywall tape is of high quality, according to many positive reviews from the masters.

Serpyanka is applicable in:

1. Sealing plasterboard joints.
2. Elimination of cracks that have appeared. To prevent the crack from growing in length along the surface, tape should be used.
3. At the borders of ceiling tiles.
4. Reinforcement of the inner corners of the wall and ceiling transition.

With all the positive characteristics of the serpyanka, there is one drawback - with a heavy load on it, stretching takes place.

Sealing joints in gypsum board

First, let's make it clear that for the joints, special gypsum putties with increased crack resistance are used. Knauf company recommends using Uniflot putty for sealing cracks; it has durability and strength, but the cost sometimes frightens off. Therefore, it is often replaced by a Fugenfüller whose price is several times cheaper.

How to close up drywall joints? Following the step-by-step instructions, sealing the joint does not require a long time, special skills and the cost of hard physical labor.

It is required to carefully prepare the surface. The joint should be cleaned of dust and small pieces of drywall. Further, the dry and clean surface must be primed.

How to glue the tape on drywall? There are 2 methods of mounting serpyanka.

If the tape is sticky then:

• You should take the tape and align its center with the drywall joint on the wall. Apply the tape carefully and slowly so that it does not "go" to the side.
• When gluing the tape to the joint, press the edges well to the base.
• For convenience, the tape is cut into 1 meter pieces.

• After gluing, the serpyanka must be covered with a finishing putty and allowed to dry.

  

If the tape does not have a sticky layer, the joints on drywall are sealed as follows:

• A layer of putty from Knauf is Uniflot or Fugen is applied to the surface with a primer. Layer thickness 1mm.
• Serpyanka is placed on the wet putty, so that its center coincides with the joint.
• Serpyanka is a little trampled into the putty. This can be done with a narrow spatula. In this case, when the edges of the tape are pressed, the rest of the putty "crawl out". They must be removed immediately.
• After gluing the tape, the putty should harden a little. On top of the tape, another layer of putty is applied, it already covers the tape, the places of fasteners of the drywall sheet.

When installing reinforced tape, it is required that the humidity in the room be moderate. At high humidity, drywall will pick up water and, if this moisture is released, the tape may not withstand stretch marks.

After drying, the entire putty surface is polished with fine sandpaper, all defects are removed.

Paper tape

Paper tape for drywall seams has not lost its relevance even now, when there are many other reinforcing materials for drywall on the construction market. The tape is used in repair work, because it has many advantages:

1. The thinness of the tape allows you to quickly level the surface after gluing.
2. When mounted on a filler surface, the wet tape retains its functionality.
3. Masters consider paper tape to be budgetary, since its price is relatively low.
4. To use the tape, you do not need to use special mixtures and materials.

The temperature regime during installation work must be maintained within the range from +18 to +25 degrees. If the temperature is too high, the air in the room is dry, and if it is too low, the humidity is high.

How to glue paper tape to drywall joints?

Paper tape is used for finishing plasterboard joints, for eliminating cracks. So that the crack does not grow, it is cleaned by making a small depression. After they are primed. After drying, apply a thin layer of putty and glue paper tape. If air gets inside, the bubble should be pierced with a needle, the air will come out.

Before you start fixing the tape, you need to check the strength of the drywall structure. With the slightest movement of the gypsum board, the tape will not help in strength.

To reinforce the gypsum board joints:

1. All drywall seams must be primed.
2. After drying, the tape must be wetted for strength.
3. A thin layer of putty is applied to the joint, and tape is glued on top with a narrow spatula.
4. All the work done is left to dry completely.
5. After the elapsed time, you need to check how the tape is adhered and apply another layer of putty on top.
6. The final action will be to grout the excess roughness and get rid of excess putty.

When installation work is carried out with a reinforcing tape, there should be no drafts. It is better to close open windows and doors.

Knauf paper tape has strength and durability. It does not tear or stretch under certain loads.

Tape with metal inserts

The tape with a metal insert reinforcing for drywall Knauf is not used to eliminate cracks and to reinforce joints, it is intended for gypsum board corners. Durable, capable of withstanding not only changes in drywall during temperature changes, but also mechanical stress on external corners. The metal strip is made of non-corrosive material.

How to properly glue the tape on drywall?

1. Apply tape to the cleaned and primed corner.
2. The center of the tape should be exactly at the corner.
3. Since the tape has a sticky layer, it does not need a putty to stick it on.
4. The tape should be glued slowly, keeping an eye on the center.
5. Since the corners in the plasterboard structure are even, the edges of the tape will lie exactly. They need to be well pressed to the surface.

From above, the tape must be covered with Finish putty, while covering the drywall fasteners to the metal frame.
