Definitions

  • the present invention relates to a dry mortar which is suitable for producing a plaster for a building surface. Furthermore, the use of 0.2 to 5 wt .-% of dispersion powder based on an ethylene-vinyl laurate-vinyl chloride terpolymers, based on the dry mortar, in a Sanierputz, disclosed for accelerated construction of the hydrophobic properties of the plaster after application.
  • Sanierputze special plasters for moist and saline building surfaces are on the market, which are also referred to as Sanierputze.
  • Sanierputze are sold in the form of dry mortars and are suitable for the production of plasters with high porosity and water vapor permeability while reducing the capillary water pipe.
  • Minimum requirements for renovation plasters and renovation plaster systems in terms of building physics are specified in DIN EN 998-1, further requirements in WTA leaflet 2-9-04.
  • Sanierputze usually consist of cements, hydrated lime, sand, mineral lightweight aggregates and various additives, such as air entraining agents and
  • the renovation plaster has two major effects. On the one hand, the evaporation level for moisture present in the masonry is shifted into the restoration plaster, and on the other hand, the salts present in dissolved form in the masonry are absorbed into the pores of the restoration plaster.
  • Restoration plasters are predominantly used in the renovation of old buildings, both indoors and outdoors, as well as for the regeneration of moistened and salty walls; especially where it depends on particularly vapor-permeable plaster, such. As in wet rooms, cellars, bathrooms, laundries, but also in Räu- which are only occasionally heated, such as churches, apartments, halls and similar buildings.
  • Repair plasters are usually applied in two layers in thicknesses of 1.5 to 3 cm. After sufficient hardening and drying of the restoration plasters, a coat or top coat can be applied. As paints but only systems may be used that are adapted to the building physics and chemical values of Sanierputzen, the water vapor permeability and hydrophobic features play thereby the decisive role.
  • a cleaning system which has a buffer plaster between a sprayed-on mortar layer applied to the masonry and a restoration plaster layer.
  • the buffer plaster contains surfactants as air entraining agents and absorbent lightweight aggregates, resulting in an open pore space of at least 30% by volume. Hydrophobing agents in the buffer plaster prevent a stronger water absorption. Salts present in the masonry can migrate into the buffer plaster without resulting in damage to the finally applied redeveloping plaster.
  • the hydrophobizing agent used is sodium oleate. From DE 2917263 a plaster is known, which is suitable in terms of its properties, such as possible water vapor diffusion, frost resistance and prevention of condensation of water vapor on the surface as Sanierputz.
  • This mortar contains a hydrophobic additive and a nonionic surfactant.
  • a hydrophobic additive for example, a mixture of sodium methyl silanolate and organostannate is mentioned.
  • the chemical additives must be precisely metered before the actual preparation of the plaster mortar mixture and after the mixed water, the lightweight aggregates and the cement in the mixer to give.
  • Restoration render mortars are known from DD 291074 which contain sodium or potassium salts of long-chain organic fatty acids, aqueous alkali siliconate solution, alkyl monosulfonate or an alkylphenyl polyglycol ether as hydrophobizing additive.
  • the previously known Sanierputze have the disadvantage that the hydrophobicity of the plaster mortar sets only after the extensive drying of the applied plaster. On heavily salinated substrates and / or under difficult drying conditions, this may cause salts to penetrate the rendering render before the hydrophobicity sets in. This leads to efflorescence of the salts on the plaster surface and can cause lasting damage to the freshly applied restoration plaster. Such problems also occur in difficult drying conditions, in which the room air is already saturated with water vapor, for example in poorly ventilated basement rooms. Furthermore, such problems may also arise because sealing measures are missing or insufficiently formed.
  • the object of the present invention was therefore to provide a generic Sanie plaster, which as directly as possible after application to the building surface has sufficient hydrophobicity to prevent penetration of salts by the Sanierputz. Furthermore, performance properties of the restoration plaster such as longevity and adhesion should be improved.

  • the air content in Sanierputzen is preferably at least 20 vol .-%, preferably more than 30 vol .-% of the total volume.

Surprisingly, it has been found in this connection that the sole use of other dispersion powders, for example based on ethylene-vinyl acetate, can not achieve any hydrophobization of the mortar. These dispersion powders also lead to significant disadvantages in terms of application, since the air pores which are important for the restoration plaster can not be kept stable.
