Bauwer Standard
Natural eco-friendly BAUWER Standard is an innovative high performance ready to mix thermal insulation plaster for internal use. It’s based on cement, lime and naturally occurring volcanic glass called Perlite. It’s used for thermal insulation, sound-absorbing as well as fire protection. Along with the insulating and sound absorbent properties, BAUWER Standard is light weight and breathable, which prevents condensation as well as protects the walls from fungus and mould growth.
In addition to levelling uneven walls you will get the following advantages:
– internal thermal walls insulation;
– dehumidification thanks to breathability;
– thermal insulation of inner and outer slopes;
– formation of a sound absorbing layer on wall structure;
– formation of acoustic insulation layer between floor joists;
– thermal insulation of roofs and floors.

The mortar mix is applied in several coats using standard plastering tools. The required thickness is ensured
by the use of guides on the BAUWER STANDARD mortar layer. The recommended thickness of BAUWER
STANDARD mortar in one application should not exceed 40-50mm. Every layer applied thereafter should be
done at least after 4 hours.
1. With the guides in place, wet the application surface with water. It is critical that the Bauwer mortar should be applied to a pre-wetted surface, which is why the surface has to be well moistened 2-3 hours
before application of the mortar.
2. Apply the BAUWER to the wall by hand using a stainless steel trowel or using a plaster spraying machine, such as PFT G4, 5.
3. Once the area between the guides has been filled, run a straight edge up against the rail guides in an
upward short left to right sawing motion to remove any excess BAUWER to achieve a flat even finish.
The surface of previous layer does not need to be well finished; a rougher surface will in fact provide a good key on which to apply the next layer.
4. Ensure the current layer surface is well wet before applying the next layer.
5. After a couple of hours, return to remove the wooden guides and fill in those areas with Bauwer
STANDARD, wet the area if required. If the mortar consistency changes during the application, just re-mix the mortar with an electric mixing drill without adding water.
6. Leave the final BAUWER STANDARD applied coat for the one day to strengthen.
7. It is recommended that applied BAUWER STANDARD insulation coat is reinforced and then levelled with BAUWER FINISH to provide a smooth finish.
8. Next day the surface of BAUWER STANDARD applied coat should be well moistened before BAUWER
FINISH application.
9. Prepare BAUWER FINISH mortar: pour not less than 5 litres of water into a clean tub of at least 15 litres capacity; empty the content of the BAUWER FINISH bag into it. The mortar is mixed with a high speed electric mixing drill until a homogeneous mixture is obtained. The mortar mix should then be left for 3-5 minutes for maturing. If required, add a small amount of water and re-mix the mass.
10. Apply a layer of BAUWER FINISH to the surface area by hand using a stainless steel trowel with pressure in an upward motion.
11. Run a stainless steel trowel over the area to finish. The BAUWER FINISH thickness should be 2.5 to 3.5mm.
12. When the BAUWER FINISH layer has dried out, uneven areas can be sanded to correct any surface
irregularities
13. The external BAUWER FINISH can be painted or wall paper applied
