Scope of application of PRAKTIK dry building mixture

Bergauf Praktik is a cement plaster specially designed for outdoor use. Using Bergauf Praktik plaster you can perform rough leveling of walls. But, after this, the wall will need finishing putty or coating. finishing material, for example, wallpaper.

Plaster Bergauf Praktik is used for application on surfaces such as:

• brickwork,
• concrete,
• reinforced concrete,
• foam concrete (with appropriate foundation preparation),
• aerated concrete,
• old cement plaster,
• old cement-sand plaster.

Composition of PRAKTIK plaster

The composition of BERGAUF Praktik plaster includes four elements: cement binder, modifying polymer additives, fractionated sand and mineral additives.

Applying PRAKTIK plastering mixture

Preparation of the solution can be done manually or by machine. Manual method. The instructions on the packaging reflect the proportions and steps proper preparation mixtures.

Manually add dry mortar into water (water temperature: room temperature) and mix everything until smooth (this process can be done manually or using a construction mixer). After 5 minutes, stir the solution again.

Machine method. In accordance with the manufacturer’s recommendations, it is necessary to first set the water requirement of the mixture (l/h) on the flow meter. Pour the mixture from the bags into the hopper, or connect the pneumatic conveying device and fill the hopper of the device into automatic mode from silo. After this, start the machine and adjust the consistency. To do this, you will need to slowly rotate the flowmeter valve.

At the second stage, start applying the solution to the surface:

1. The solution is applied to work surface using a mortar mixer (jet with a gun). In addition, using a plastering ladle (trowel), the solution can be manually applied to the surface.

2. Level the surface using building regulations(type: h; length: 0.5 - 3 m).

3. After the solution has set on the surface (that is, it stops sticking when pressed lightly), the technology requires it to be re-leveled using a building rule (type: trapezoidal; length: 0.5 - 3 m).

4. After the solution has hardened on the surface (touching with a little force leaves only light dents), the technology requires “glossing”. For this process you will need a grater with a foam (felt) coating. With its help, water is applied in a circular motion to the surface of the plaster, it promotes the release of cement milk.

5. Level the cement laitance over the entire surface with a construction spatula. High-quality execution of this operation replaces the subsequent process of surface puttying.

Advantages of PRAKTIK plaster

Bergauf PRAKTIK is a plaster, the production of which minimizes the costs of packaging, advertising, etc. This contributes to the formation affordable price, which certainly attracts many consumers.

Ordering goods is available only from 1 pallet

Plaster for leveling walls for subsequent finishing putty. It is used for work on brickwork, concrete (over 6 months), reinforced concrete, aerated concrete, foam concrete*, old cement and cement-sand plasters. Recommended for facade and basement work.

For machine and manual application.

Specifications

*subject to appropriate preparation of the base

Compound

Cement binder, fractionated sand, mineral additives, modifying polymer additives.

Preparation of the solution

For machine application:

1. Pour the dry mixture into the receiving hopper.
2. Set the initial water flow*.
3. Bring the consistency of the solution to the required consistency by adjusting the water flow level.

* Water consumption level depends on the make and model of the machine.

For manual application:

1. Mix the mixture with water (from +10 to +25 0 C) in the following proportion:

- per 1 kg of mixture - 0.20 -0.23 liters of water;

- for 30 kg of mixture - 6.0 -6.9 liters of water.

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

Preparing the base

The base must be cleaned of dust, dirt, oil stains - anything that can impair the adhesion of the material. The prepared surface must be treated with a primer.

Operating procedure

1. Apply a base layer of the required thickness, but not exceeding 25 mm.
2. Remove excess as a rule, level the surface.
3. The surface can be completely wiped down after 4-5 hours (times are based on the thickness of the applied layer: 25 mm).

Attention!

If the required leveling thickness is more than 25 mm, it is necessary to apply the plaster in layers, allowing each layer to dry. The number of layers is no more than 3. The thickness of the first layer is no more than 25 mm, each subsequent layer is no more than 20 mm. If the required leveling thickness is more than 60 mm, use reinforcing metal mesh. The drying time for each layer is at least 3-5 days.

Safety precautions

Avoid contact of material with eyes and respiratory tract.

Storage

The guaranteed shelf life in a dry place and original packaging is 12 months from the date of manufacture.
