Safety precautions

Before starting work, make sure that the window and doorways closed, there are no drafts in the room, the air temperature is in the range from +5 to +25 ° C and such temperature regime kept indoors for at least 5 days before starting work and three days after application.

The base must comply with the requirements of SP 29.13330.2011; when carrying out work on the “Warm Floor” system, it is recommended to turn off the heating at least 2 days before the start of work.
The surface of the base must be cleaned of dirt and dust, paint coatings and glue, peeling old coatings and oil stains - everything that can impair the adhesion of the material to the base.
Weak areas of the base, protrusions and irregularities must be removed by grinding or milling.
All cracks, deep potholes in the base, joints of slabs must be opened a day before the start of floor leveling work, cleaned of dust, treated with Bergauf TIEFGRUNT primer and filled with a thickly diluted Bergauf Base mixture.
The prepared base must be treated with Bergauf TIEFGRUNT primer
Dry and highly absorbent substrates must be primed twice. Allow the first coat of primer to dry for 1 hour before reapplying. Floor installation work should be carried out no earlier than 4 hours.

If the base surface is not primed, cracks may occur during the hardening period of the floor and a decrease in the strength of the hardened mortar .

Use clean containers and tools to prepare the solution.

Mix the mixture with water (from +5 to +25 °C) in the following proportion:

The dry mixture is gradually added to the water.

for 1 kg of mixture – 0.17 – 0.19 l of water;
for 20 kg of mixture – 3.40–3.80 l of water
for 25 kg of mixture – 4.25 – 4.75 liters of water.

Stir until smooth**.
Wait 3-5 minutes until all chemical reactions are completed.
Stir again

** Mixing is recommended to be done using a special mixer for dry mixtures or conventional drill with nozzle, speed no more than 500 per minute. At a high number of revolutions, the mixture will involve a large number of air, which can negatively affect the quality of the surface - the formation of bumps and craters is possible.

Attention! The properties of the product are guaranteed only if the proportions of mixing with water and the procedure for preparing the solution are strictly observed.

The mixture must be consumed within 1 hour from the moment of preparation.

Install the beacons parallel to each other, so that during application and leveling they are like rails for the rule that will be used to level the mixture. It is prohibited to install beacons on gypsum mixture; it is recommended to use a quick-hardening mixture, for example, Bergauf Easy Master.
It is necessary to stick damper tape around the perimeter of the room (the height of the tape should be 1 cm greater than the thickness of the Bergauf Base application, minimum thickness tape 5 mm).
After preparing the solution, distribute it evenly between the beacons using a trowel or spatula. Application must be done from the far corner (in relation to the doorway), gradually moving towards the exit.
The thickness of the application should exceed the height of the beacon by 1-3 mm.
After distributing the solution, it is necessary to level it using the trapezoidal rule.
Place the rule on the beacons, and then, without breaking away from the beacons, pull it “towards you,” holding the rule at an angle of 60°.
Remove the remaining mixture remaining on the rule with a trowel and reuse.
Expansion joints are created 24 hours after the floor is applied.
Expansion joints should be perpendicular to each other, the area between the seams should, if possible, coincide as much as possible with the shape of a square. The distance between parallel seams should be 3-6 m, the width of the seam should be 3-5 mm, the depth should be a third of the thickness of the screed. The seams must coincide with the axes of the columns and the seams of the floor slabs.
Before further work(laying the covering, pouring the finishing floor) the seams are filled with mortar leveler Bergauf Base or other suitable product.

When installing a heated floor, you should be guided by SP 29.13330.2011.

Attention!

When installing floors in rooms with complex geometric shape It is necessary to cut expansion joints after the mixture has hardened. Expansion joints must be arranged in doorways, narrowing in rooms with an irregular geometric shape and with a diagonal of more than 10 meters. Also, when installing the floor, you should repeat the existing ones in the base. expansion joints.

During the hardening period (the first 5-10 days after pouring), avoid drafts in the room and direct contact with the surface. sun rays so as not to cause premature drying of the floor and the appearance of cracks.

Passage on the leveled surface is possible after 48 hours*.

Turning on the “Warm Floor” is possible no earlier than after 14 days.

Before installation finishing coatings the surface can be leveled self-leveling floors Bergauf.

Scope of application of the mixture for preliminary leveling of Base floors

To implement cement screed the best way Bergauf Base mixture is suitable. Application modern material will facilitate the process of leveling the floor. Bergauf Base mixture is applied in an even layer from 6 mm to 50 mm. It is intended for application to reinforced concrete slabs ceilings or monolithic concrete, base (rough) screed, self-leveling floors, “warm floors”, chipboard, gypsum fiber board, wood, expanded clay (if used as a rough screed and with appropriate preparation of the base). The uniqueness of the mixture Bergauf Base also lies in the possibility of its use in rooms with both normal and humidity exceeding 60% (for example, a bathroom, bathhouse, etc.).

Dry composition construction mixture Base

The composition of the Bergauf Base mixture includes: cement binder, mineral fillers, fractionated sand and modifying polymer additives.

When storing the material in sealed original packaging in a dry room, the manufacturer guarantees the preservation of all quality characteristics BERGAUF mixtures Base for 1 year from the date of its release.

Applying mixture for preliminary floor leveling Base

To obtain a high-quality flat Base floor, a number of requirements must be met. The base of the floor must have grade strength, with indicators not less than M 100. To ensure better adhesion of the mixture to the floor surface, the latter must be cleaned of dirt and dust (including construction), oil and greasy stains and damaged old coatings. Carrying out floor cleaning measures improves the adhesion of the material to the base. In addition, the prepared base should be treated with a primer; “Bergauf” (“Tiefgrunt” or “Primer” - depends on the specific type of base) is best suited.

No mixture preparation required special effort and time. It is necessary to mix the mixture with water (the water temperature should be in the range +5°C - +25°C) in the following proportion: for one kilogram of the mixture you will need ≈ 0.17 - 0.19 liters of clean (tap) water; and for 25 kilograms of dry mixture, respectively, ≈ 4.25 - 4.75 liters of water. After stirring the mixture until smooth, wait 4 - 5 minutes. After repeated mixing, the solution is ready for its intended use.

The manufacturer draws the attention of its consumers to the need to strictly adhere to the proportions of dilution with water and the progress of preparing the solution. Compliance becomes the key for long years use of the future floor!

It is unacceptable for the mixture to enter the respiratory tract and eyes of a person!

Manufacturer recommends manual method applying the mixture. After applying the prepared Bergauf Base solution to the prepared base, it must be distributed evenly. Leveling the surface can be done using a construction spatula or a rule.

In the case of pouring bases with complex geometric shapes, it will be necessary to organize special expansion joints (or introduce compensating materials into the structure of the poured floor, or cut appropriate long holes (seams) immediately after setting applied mixture). Such expansion joints must be provided in doorways, on planes with a diagonal measurement of 10 meters or more, and in narrow parts in rooms with an unusual geometric shape.

Cement hardening period Bergauf ties Base takes two weeks after pouring. These days, you need to avoid direct sunlight and drafts in the room being repaired on the surface of the screed.
