How to glue serpyanka and paper tape on the drywall joints

Serpyanka for drywall is a thin mesh tape that is made of fiberglass. Usually its width varies between 4.5-23 cm, and it is used for the reinforcement of drywall joints. No overall plasterboard construction can not do without the use of reinforcing tape at the stage of puttying. This tape allows you to avoid the appearance of cracks in the finish layer. Also for this purpose paper tape can be used, but it will be discussed a little later.

Preparation of drywall before using reinforcing tape

Serpyanka width of 5 cm is enough

Before the tape for drywall joints will be used, you need to prepare these joints. It is clear that by this time the construction of the drywall has already been fully assembled (the screws are screwed in as it should be and do not stick out) and ready for puttying, and then for the finishing. Preparation includes the following steps:

• from the edges of drywall chamfer removed . She could be shot in advance with a special planer. But this can be done locally with a regular wallpaper knife. The depth and width of the chamfer of 5 mm will be sufficient. In this case, the chamfer is removed at a small angle (200-450);
• cleaning the surface from dust . It is required that the putty is firmly held in the created hollow and securely fastened the sheets to each other before the grid is used for the seams of drywall;
• priming joints is needed for better adhesion so that even a hint of the presence of seams is left;
• the seams are puttied . In this case, you will need to take a putty, like thick sour cream and no lumps. It is applied in the created hollow between the joints GKL. It is quite normal that after drying, a small ditch will appear at the junction. The surface will be puttied once more when the gypsum plasterboard seams are to be sealed. Then all the bumps will be removed;
• if the putty was applied roughly and hillocks formed, then the reinforcing tape does not lie flat. Therefore, it may be necessary to sandpaper the seams so that they are flush with the sheets of drywall.

In fact, this preparatory robots end. Joints prepared for further processing.

What reinforcing tape to choose

Tape for sealing the seams of drywall can have a different look and consist of different materials. It is not only its width or thickness, but also in shape.

Serpyanka and paper tape for sealing drywall joints

The most popular type of reinforcing tape is serpyanka. It is made of fiberglass, which means you can not doubt the strength. The mesh structure ensures that all excess putty will be out of the serpyanka during its use . As a result, it will lay on the seams as thin as possible. For greater ease of use, one side of the serpyanka is coated with an adhesive. Although this point is not particularly important if it is glued to putty.

Despite the existence of serpyanka for many paper perforated tape for plasterboard remains the main tool for sealing joints. It is thinner than a serpianka, but at the same time it remains durable, although it is paper. Also, it does not stretch against certain concerns. But there must be a perforation on such a tape so that when applied, all air and excess putty are removed.

You can also mention a damper tape or a tape with a metal liner, but it does not make sense to use them for embedding GKL joints.

What are the features of serpyanka for drywall?

1. It has a high level of durability.
2. Durable and will last all the years that will pass until the next repair.
3. Not afraid of aggressive environment.
4. It tolerates shrinkage and vibration loads.
5. It prevents the appearance of cracks due to the formation of a strong adhesion to the binder (putty).
6. It has a relatively low cost.

How to reinforce the seams serpyankoy

Recall that we have the joints between the plasterboard already clipped (chamfer removed) and once filled. This was done along with other preparatory work. Now consider how to putty drywall seams with tape. Serpyanka width of 5 cm will be quite enough. The length of the coil is easy to calculate by adding the length of all the joints. You can take a little more in case of marriage, if work with serpyanku carried out for the first time.

Serpyanka should be glued so that its middle is clearly along the seam. In this case, with its help, the greatest effect is achieved. Small displacements will not be critical, but if 70% of the serpänka are on one side of the seam and 30% are on the other, then the quality of such reinforcement of the seams is in great doubt.

There are two approaches to the account of how to glue serpyanka on drywall. In the first case, it is glued to the seam due to its adhesive surface. After that, putty is applied to it, which fixes the serpyanka and reinforces the seams. However, the second approach is considered more correct.

A putty is applied with a narrow trowel along the entire length of the seam. Then serpyanka is glued over the putty. First, you can press it with your hands. However, after this, it is necessary to hold it with a wide spatula with a slight pressure several times. Due to its cellular structure, the serpyanka for drywall will putty putty through itself. It will go straight out through the cells. Serpyanka will be more indented, and excess putty will be removed with a spatula.

Three stages of using serpyanka

The reinforcing tape itself is cut in advance. You can cut in place, but it is not always convenient. In any case, it will be necessary to hold the surface several times with a spatula, as if to press a serpyanka, squeezing out excess putty from under it. They are then removed with a spatula (if many) or smeared over adjacent areas (if small). If you need to join pieces of serpyanka (vertical and horizontal joints intersect), then this is done with an overlap, but only a few millimeters. Now there should be no questions about how to glue serpyanka on drywall.

Strengthening seams with paper tape

Despite the enormous popularity of serpyanka, many continue to use paper tape for sealing seams. It is chosen not only because of its low cost. Despite the low price, it quite successfully performs the same functions as the serpyanka reinforces the seams. However, there are certain features that you need to pay attention to if you use perforated paper tape for drywall seams. It has the following advantages:

• paper tape thinner serpyanka . Due to this, the putty consumption for the entire drywall is minimal;
• low cost ;
• ease of use . Paper reinforcing tape is not more difficult to glue than serpyanka;
• good adhesion with putty . Paper perforated tape does not disappear during operation, and at its completion it firmly secures the seams.

After all the preparatory work, the paper tape should be put in the water for a few minutes. Thanks to this simple procedure, it will not lump in a heap during operation. After removing it from the water, it must be pressed. Just walk on it with a spatula to remove excess water. After this paper reinforcement tape for drywall can be used for its intended purpose.

It is undesirable for a beginner to work with pieces of paper tape that are longer than two meters. Due to the large length of the material, many mounds can form, and also the tape can move out from the center of the seam.

Putty is applied to the joint transversely to the seam line. After that, it is smoothed with longitudinal movements, and then reinforcing tape is laid over it. Sealing of drywall seams with paper tape is carried out using a wide trowel.

The smoothing of the reinforcing tape is carried out using a wide trowel

The tape is smoothed from the center to the edges. No need to try to smooth it out at once. This is done in several movements, and constantly need to make sure that from this paper tape does not move to the side, held in the center of the seam. Also, a wave is usually formed, which will need to be cleaned with a spatula in several passes.

Excess putty smeared on neighboring GCR. Working with a reinforcing tape requires patience, because the rush will damage the material. Therefore, for beginners, a serpianka for drywall is a more suitable choice.
