DisboCRET 510 1K-Acryl-Feinspachtel

Plasto-elastic dispersion-based filler/surfacer (easy to spread) and undercoat in one product. Used for filling pores or shrink holes and as patch filler on concrete surfaces – also suitable for application on concrete with existing coatings. 

LV Texte

Field of Application

For filling pores or shrink holes and partial filling of surface defects and spallings up to 1 mm deep.
Used for equalising unevenness and surface roughness during repairs. May be used as a modelling material for texturing repairs on fair-faced or textured concrete, to match the aspect of surrounding surfaces.

Material Properties

  • Ready for use.
  • Easy to spread.
  • Covers reticular surface cracks < 0.2 mm wide.
  • Economic, easy to apply.
  • Plasto-elastic.
  • Alkali resistant.
  • Water vapour permeable.
  • Reduces the effects of CO2 and SO2 exposure.
  • Spreads nearly to base level without lapping.
  • Meets the requirements of EN 1504-2 and DIN V 18026: Surface protection systems for concrete

Suitable Substrates

Normal, heavy and lightweight concrete, Disbocret® fillers/surfacers, mineral renders/ plasters and existing coatings.
The adhesive tensile strength of substrates must be  1.5 N/mm2 on an average, with a minimum individual value of 0.5 N/mm2.

Substrate Preparation

Mineral substrates
The substrate must be sound/solid, clean and free from loose material that may prevent good adhesion. Remove all adhesion diminishing substances, e.g. oils, fats/greases, by suitable methods. Clean soiled surfaces, e.g. infested with moss and algae, and remove vitreous, unsound cement laitance by suitable blasting medium and equipment. The substrate must be free from corrosive substances (e.g. chlorides). Substrates with normal absorbency must be moistened and should show a flat moist surface before applying the Filling Coat. Prime highly absorbent mineral substrates with CapaSol LF according to the factory specification.

Coated substrates
Check existing coatings for sufficient adhesion to the substrate and remove non-adherent coatings. Clean sound, adherent, non-chalking existing coatings. Under normal conditions a priming coat is not required. As in practice various types of coatings may occur, the planned surface coating system must be tested in advance by a trial coating to verify its functionality. 

Spallings (defects), pores and shrink holes
To achieve a uniform, sufficiently thick protective coating, all spallings, cracks, high unevenness or surface roughness must be thoroughly repaired using adequate Disbocret® System materials according to the manufacturer's recommendations. Small pores and surface roughness can be filled and equalised with Disbocret® 510 Füllschicht · Filling Coat.

Preparation of Material

Disbocret® 510 is ready for use, but should be stirred before application. The material can be thinned up to 5% with tap (potable) water, depending on application method, weather conditions or substrate requirements. Manual application: The drying time may be reduced by adding up to 20% of premixed CEM I (PZ 35). Spray application: Adjust to spraying consistency by adding max. 1–2% of tap (potable) water, if necessary.

Method of Application

Apply with brush, roller or spraying equipment.
The material is applied in one or two coats, depending on substrate requirements, by crosswise application, filling all shrink holes and pores. 
If the texture of substrates must be preserved, then the material has to be applied by rubber scraper (spread to base level). 
If applied with cement, the trowel marks can be removed by grinding after having allowed to dry for a sufficiently long period. 
During airless spray application, the filter should be removed if necessary, in order to avoid clogging. 
Nozzle size: 0.035 inch. In Germany: Follow VOB, part C (DIN 18 363, paragraph 3.1.3). The material should not be applied e.g. in direct sunlight or on sun heated substrates, during strong wind, fog or rain, high relative humidity or imminent rain or frost, etc. Protective tarpaulins should be used, if necessary.

Layer Thickness

Spreading on the complete surface nearly to the base level without lapping, max. 1 mm. A higher layer thickness can be achieved by multi-layered application.

Surface Coating System

After a drying time of 24 hours, Disbocret® 510 Filling Coat can be coated with the following materials: Disbocret® 515 Betonfarbe · Concrete Paint Disbocret® 518 Flex-Finish A finishing coating can be omitted, provided that Disbocret® 510 is applied in two uniform coats onto the complete surface of normal or heavy concrete. However, efflorescence or other adverse effects may occur.

Consumption

Approx. 400–700 ml/m2 per coat.

Application Conditions

Min. 5 °C and max. 40 °C for material, substrate and ambient air.

Drying/Drying Time

At 20 °C and 65 % relative humidity: dust-dry after approx. 1 hour, rainproof after approx. 2 hours and recoatable after approx. 24 hours.

Tool Cleaning

Clean tools immediately after use with water.
