Damping tape for floor screed: purpose, properties and installation

With the development of the construction industry, secondary materials such as damping tape for screed, have become very popular. The reason for this is ease of use and no need to invent various devices from improvised means.

Damper tape for screed: the purpose and consumer options

Not everyone knows how to make a floor screed with their own hands. A video of this process often misses important details. One of these nuances is the need to provide protection against linear expansion of concrete when heated. From the physics school course everyone knows that any substance expands as the temperature rises. Whatever the proportion of floor screed solution, when it hardens, heat is released, which leads to a significant expansion of the screed.

Already calculated that every m? area causes an increase in linear dimensions of 0.5 mm. That is, in a room of 20 m? concrete in the process of solidification may expand by 1 cm. What it will lead to is not difficult to guess. Resting against tougher walls, the coupler will swell and crack, destroying the already laid finish.

Previously, this problem was solved by the fact that wooden bars of the required width were laid along the perimeter of the walls at the floor level. They served as shock absorbers. However, wood has such disadvantages as susceptibility to rotting and small damping ability. In this regard, and was designed damper tape for floor screed. It is made of polyethylene foam. This material has excellent damping qualities.

Damper tape for tie is produced in the form of tape, coiled into rolls. Their length can be from 10 to 100 m. The width of the product is 5 – 15 cm, and its thickness is 3 – 10 mm. Along the entire length of the strip there are perforated cuts every 10 mm. They are needed in order to easily tear off the excess material flush with the surface of the screed after it is cured.

Damping tape for screed has many positive qualities that are especially appreciated by builders:

  • very little thermal conductivity and low sound permeability;
  • moisture resistance and water resistance;
  • the temperature difference is not terrible for her;
  • environmental friendliness;
  • long service life.

Among other things, this material is not expensive (from 0.5 USD per minute meter).

Helpful advice! Cut the excess damper tape is necessary only after laying the topcoat. After that, the plinths are installed, which completely close the seam.

All manufacturers make various additions to the basic parameters of the material. To date, there are 3 main varieties of damping tape for ties:

  1. Direct or ordinary.
  2. Having a “skirt.” In the lower part of such a ribbon there is a skirt of a thinner waterproof material. She bends to the floor, preventing the liquid from penetrating under the tape to the walls.
  3. Self adhesive An adhesive layer is present on one side of the surface under the film protection. It is very convenient to mount such tape as it does not need additional fixing.

Helpful advice! When sticking a self-adhesive tape, it is not necessary to immediately tear off the entire protective layer. This should be done as the material is pasted on the walls.

If the tape has a sticky layer, then it is enough just to glue it around the perimeter, skirting all the architectural forms, ledges, niches, columns. If there is a “skirt”, it is bent to the floor, so that water cannot get under it.

If the damper tape for the tie is normal, then it is installed around the perimeter and attached to the wall in any convenient way: with small studs, a construction stapler or glued with glue. The task is to completely cover the entire perimeter with a tape.

Helpful advice! Standard material is designed for the load of such a screed, the width of which does not exceed 10 m. If the room is larger, then the damping layer should be increased.

Using modern auxiliary building materials, you will avoid many inconveniences and disappointments.
