Damper tape for floor screed: designation, properties and installation

Damper tape splicers: the purpose and parameters of the consumer

Not all thoroughly know how to make a screed floor with their hands. Video of this process often miss important details. One such detail is the need to provide protection against a linear expansion of concrete when heated. everyone knows from school physics course, that any substance expands when the temperature rises. Whatever the proportion of the solution for a floor covering, during solidification is released thermal energy, which leads to significant expansion of the screed.

It is estimated that every m² area causes an increase in the linear size of 0.5 mm. That is, in the room 20 m² concrete during solidification can be expanded to 1 cm. Where will this lead is not difficult to guess. Resting in a hard wall,

strainer vspuchilis and crack, destroying the already stacked topcoat.

Previously, this problem is solved in that along the perimeter walls at floor level stacked wooden blocks required width. They served as shock absorbers. However, the tree has disadvantages such as rotting and small damping capacity. In this regard, and the damper strip for floor screed has been developed. It is made of polyethylene foam. This material has excellent damping properties.

Damper tape tie is made in the form of tape is wound into rolls. Their length may be from 10 to 100 m Width of the body 5 - 15 cm., And its thickness is 3 - 10 mm. The entire length of the band has perforated sections every 10 mm. They need to easily pick off any excess material flush with the surface screed after its solidification.

Damper tape screed has many positive qualities that are particularly appreciated builders:

• a very small thermal conductivity and poor permeability to sound;
• moisture resistance and water resistance;
• temperature difference it is not terrible;
• environmental friendliness;
• long service life.

Among other things, this stuff is not expensive (0.5 USD per running meter).

Useful advice! Trim any excess ribbon damper is only necessary after laying finish. After this set plinthWhich completely covers the seam.

Useful advice!When the label adhesive tapes do not need to immediately interrupt the entire protective layer. This should be done as far as the material wall stickers.

How to create a damper layer on the perimeter of the room

If the tape has an adhesive layer, it is enough just to glue around the perimeter, bypassing all the architectural form, protrusions, recesses, columns. In the presence of "skirt", it folded to the floor, so that under it could not get water.

If the damper tape splicers usual, it is set on the perimeter and fastened to the wall in any convenient way: by small nails, staple gun or paste adhesive. The objective is to completely the entire perimeter was closed with tape.

Useful advice! The standard material is designed to load from such a coupler, whose width does not exceed 10 m. If the room is greater, the damping layer must be increased.

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