Building materials today correspondgrowing consumer demands and health standards. Glue "Perlfiks" for drywall from the company "Knauf" is very popular. Its properties and features of the application should be considered in more detail.
This is a manufacturer with a world name, producing building products. Its materials are used for internal and external decoration, as well as in the machine method of application.
The organization was created in 1932 in Germany by twobrothers - Alphonse and Karl Knaufy. Their company has proven itself as a manufacturer of high quality finishing materials. Now she has reached world leadership in the construction industry.
The first plant was opened in Bavaria in 1949.Initially, the company produced only gypsum mixes, and from the beginning of 1958 began to produce gypsum plasterboards. In order to gain a foothold in the market and expand the range of products, Knauf in 1970 acquired a stake in Deutsche Perlite GmbH (the company produced dry cement mixes), and soon a factory for the manufacture of fiberglass insulation in Shelbyville (USA). This diversified risks and brought the organization to a new level.
In 1993, Knauf opened plants in the CIS countries. Today it is a successful company with a worldwide reputation for the production of high-quality and durable materials.
Glue "Perlfiks" is used only insiderooms with normal and high humidity levels. It is designed for gluing drywall, foam plastic, polystyrene foam, mineral wool and gypsum tiles with a matte base.
The mixture is suitable for both warm and not.heated rooms. It is not recommended to use the product in places where there is the likelihood of direct water entering the outdoor material. Also, do not apply glue to wet walls.
The life of the mixture is several decades. Glue "Perlfiks", the characteristics of which are presented by the manufacturer, has good adhesion to concrete base (0.6 MPa).
Due to the high content of gypsum mixhas a high compressive strength (10.9 MPa) and bending (3.4 MPa). When working, Perlfix glue seizes for 30 minutes. This property allows you to make adjustment of drywall sheets using rules or construction level.
Seven days is a period of complete drying of the Perlfix adhesive. Consumption of gypsum assembly mixture is 5 kg per 1 m2 surface to be treated. To obtain a high-quality and reliable result, it should be operated at a temperature not lower than +5 ° C. Water consumption per bag (30 kg) is 16 liters.
Glue "Perlfiks" is an environmentally friendly and safe for health material. It is packaged and delivered to the market in paper packs of 15 and 30 kg each.
Keep the glue "Perlfiks" ("Knauf") need to dryindoors, as its composition includes gypsum. This is desirable to do on wooden pallets, which will ensure good air flow around the bags. Such precautions will prevent the dry material from becoming wet when the humidity in the room is high.
If the package has been damaged or opened, the adhesive should be poured into a whole bag or hermetically packed old bag. The recommended shelf life of the mixture is 6 months.
Glue "Perlfiks" ("Knauf") has several advantages.Works involving the mixture are less noisy and difficult. The material is applied with a ribbed spatula to the whole sheet or cakes. Profile and fasteners are additional costs for repairs. Therefore, Perlfix will be a more economical option.
Advantages of glue are also in its versatility. They are easier to maneuver when leveling the walls, as opposed to profiles. They can also carry out small putty work.
First you need to determine the consumption of material oncultivated area. There are two basic ways to use Perlfix glue. Consumption for gypsum plasterboard depends on the irregularities of the wall and the thickness of the material deposited
To begin with, the wall is cleared of fragments.delamination, pollution. Before pasting the gypsum plasterboard, it is worth priming the surface, whether it is brick, plaster or a gas concrete wall. It is better to use special products "Knauf".
For mixing Perlfiks glue, you need a plastic container. When mixing water and dry mix adhere to a ratio of 1: 2. Water is poured into the container, then plaster of construction adhesive is poured.
Mixed material construction mixer.As a result, a homogeneous mass without lumps should form in the container. The solution should look like a creamy mass. If the mixture turns out to be very thick or liquid, you need to add water or dry mixture, respectively.
It is recommended that when mixing, gradually pour the glue into the container with water to achieve a more uniform consistency of the solution. The finished mass is used in work for 30 minutes.
Glue is applied dotted at a distance of 30-35 cm."Perlfiks" should be applied on the middle line of the sheet in one row. And for sheets over 10 mm thick, glue is applied in two rows and around the perimeter. After that, press the sheet to the wall from the bottom up. Then with the help of the mallet and intermediate rail it is aligned. Due to the elasticity of the adhesive, you can safely adjust the sheet for 10 minutes to the desired result.
If the walls have large drops or pits deeper20 mm, it is recommended to use drywall stripes and adhesives to get a flat surface for installation. It must be remembered that if the solution began to dry, then water can no longer be added to it, otherwise its quality will drop significantly.
