In the construction of various objects, a tape made of bitumen or butyl rubber is often used, its main purpose is waterproofing various structures.
Quite often, it is used when installing windows and doors, installing roofs, at the joints of floors and ceilings with walls, for corners. There are tapes of various manufacturers on the market, but their basic parameters are similar.
The structure of the waterproofing tape
Structure:
- Outside, the film is most often covered with aluminum foil, which is represented by a reinforced structure, but there are also tapes on the market based on other materials, as well as in various colors.
- It is based on a layer of bitumen or butyl rubber, which easily adheres to any surface and at any angle.
- From above, the material is covered with a special protective film, its task is to prevent the tape from sticking and drying itself.
Install the film on a specially prepared and cleaned surface.
When carrying out waterproofing work in the places of installation of door and window blocks, the tape should be glued before the complete expansion of the construction foam occurs, this will allow the material to fully stretch and fix tightly.
The price of this product depends on both its width and the manufacturing company.
An acquaintance with its various types of structure and application will help to choose a waterproofing material from a variety of proposals.
Installation technology
Installation of waterproofing tape, regardless of its type and manufacturer, must be carried out in accordance with the following rules:
- Thoroughly clean the work surface from debris and dust. The base must be treated with the composition "Kalmatron-Elastic" or "Kalmatron-Acrylast" 1 mm thick.
- The self-adhesive tape is placed in the working position and smoothed with a spatula until all air bubbles are removed. The strips are joined at the ends with an overlap of at least 5-7 cm.
- Next, you need to apply a second layer of elastic waterproofing with a thickness of 1 mm. After 5-7 days, the waterproofing coating can be used.
Outer tape
When installing waterproofing using a special tape, outside buildings, one is used that has increased strength to mechanical stress and temperature extremes. Self-adhesive waterproofing tape "Nikobend" is made specially for use in the installation of PVC windows, it is based on polypropylene.
PVC window tape, the main characteristics of self-adhesive: highly durable, butyl-based, has excellent adhesion to surfaces of any material.
Window tape does an excellent job of protecting against various moisture; its use makes it possible not to use expensive sealants. Window tapes, a functional feature of these films is its ability to remove condensate that settles on the building foam, as well as to prevent moisture from entering the premises from the outside.
Outdoor work on gluing tape
"Tape-PSUL". It has similarities with foam rubber, copes well with excess moisture, which is formed during the full formation of the foam used for installation work on the installation of door and window blocks.
A distinctive feature of this product is its foam protection from direct sunlight. In addition, due to the reliable protection of the foam, there is no urgent need to plaster door and window slopes, and this allows them to be installed even at negative air temperatures.Great for window mounting.
What material to choose for waterproofing in the bathroom
Let's analyze the advantages and disadvantages of the most popular materials for waterproofing a bathroom.
Oleechnaya waterproofing
For this type of insulation, roofing felt and / or bitumen-based roofing felt are used. But their service life is significantly inferior to more modern materials based on fiberglass and various bitumen-polymer mixtures.
Their main feature is that the installation is carried out by surfacing the material on the surface or gluing. In hardware stores, they are sold in rolls, which are convenient to use during the installation process.
Benefits:
- Affordable price and wide range.
Disadvantages:
- Gluing and roll materials require careful preparation of the base (floor or wall). Various roughness and irregularities are unacceptable, which can further affect the quality of the functioning of the material. In addition, this type of material requires certain knowledge, skills and professional skills for high-quality and reliable installation.
Coating waterproofing
For this type of work, ready-to-use mastics and emulsions are used. Some are prepared just before the waterproofing stage of the walls and ceiling.
Types of coating waterproofing:
- bituminous and bitumen-polymer
waterproofing (relatively cheap, but quickly becomes unusable, has an unpleasant odor); - polymer-cement
(excellent adhesion with a wide variety of materials provides a high level of material reliability), which can be used for the construction of a "warm floor"; - acrylic
- the most modern waterproofing of all presented in this range, environmentally friendly and very reliable.
Waterproofing based on penetrating compounds
It is produced using special chemical compounds. They are able to penetrate into the micropores of the concrete base to a depth of 20 cm. Then, crystallizing, they create a reliable high-quality hydro-barrier.
The use of these materials requires literacy and knowledge in the installation process in order to maximize the capabilities of the materials without spoiling their functionality by improper installation. This type of waterproofing is ideal for bathroom floors.
Waterproofing films
They are a new, but already very popular way of creating hydro-barrier in bathrooms. The high cost of this type of material fully compensates for the costs, because with such protection, repairs in the bathroom are not in danger.
The range of choice of film materials is quite wide. It should be noted the films for waterproofing Ondutis D (RV) and Smart D (RV), which have already proven themselves in construction work. The woven base and a special adhesive layer on one side significantly speed up the process and simplify installation. Thus, even people without construction experience can cope with the installation of waterproofing films in the bathroom.
Interior tape
When carrying out waterproofing work inside the premises, a diffuse tape is used, it is she who will block the ingress of moisture from the side of the mounting foam inside.
Italian waterproofing vapor-permeable tape "Plaster", has excellent performance in terms of reliability and durability, and also sets high criteria for moisture and steam protection. It is based on a special bitumen tape reinforced with special polyethylene. From the outside, it is covered with aluminum foil, adhesive strips, have silicone protection, and its thickness is one and a half millimeters.
The scope of this tape is not limited to any of the building materials; it adheres perfectly to concrete, ceramic, cement and other walls.Available in four different colors of the outer film, it can also be easily painted in any color. On sale there are rolls from five to ten meters long, and the width can range from five to fifteen centimeters.

Internal work on gluing tape
Polyurethane joint sealing tape "Masterflex", it is distinguished by elasticity, resistance to mechanical stress, high protection against the ingress of water under pressure. When installing this film, the contact surfaces need careful processing, but at the same time it is not selective to their composition. This tape is easily glued to surfaces with high humidity, but for excellent tension and adhesion, you can fix it with nails at a distance of twenty to twenty-five centimeters. Seams are sealed with this material.
Roofing tape "Ecobit", is used for waterproofing the roof, and its area of application is not limited only to this, it is successfully used when installing windows, pipes and doors. Tape for plastic windows is completely uncritical in the choice of materials on which it will be glued.
It is distinguished by its reinforced reinforced layer and outer aluminum or copper coating. Outside, the tape is protected by polyester, reaches thirty centimeters in width, covered with a silicone film, fixed on any cleaned surface, and porous ones need to be treated with special primers.
Butyl rubber waterproofing tape for windows "Liplent", the place of application is internal window slopes.
There are three types of such tape on the market:
- It is based on polyethylene, fiberglass as a reinforcement, covered with aluminum foil from the outside. Butyl sealant, acts as a mite layer.
- Waterproofing tape, the main composition is butyl sealant.
- Knauf has excellent elasticity, is made of polyester, has a long service life, and is used as a hydr insulator in various facilities.

Basics of using waterproofing tape.
Before using any waterproofing tape, it is necessary to thoroughly prepare the surface, since the quality of adhesion and service life depend on this. All listed materials are recommended for use. They are used for sealing works in bathrooms, swimming pools, various tanks, roofs and maintenance systems, as well as for sealing cracks in walls, joints and joints.
The common distinguishing feature of these tapes is their ability to perfectly interact with various types of building surfaces, as well as those treated with adhesives, mastics and paints.
Before using, you should select the tape that fits in width, determine the required length, remove the protective film and press the tape to the beginning of the joint, gradually spreading it over the entire surface, additionally pressing it with a special roller, trying to remove all the air. Only after this is the polyurethane foam applied, after the complete expansion of which the tape is finally fixed and stretched.
It is important to remember that in the corners of deformation, the tape is applied in the form of an omega loop. Also, the tape is applied wider than the joint by about six centimeters. The second layer is laid along the edges of the tape, leaving the middle free, while the bottom layer should already be under the dried one.
By following the steps outlined above, you should be able to create a great waterproofing joint.
