Description

Keim Granital is a classic mineral silicate based paint which gives a matt finish on all forms of mineral substrates. Keim Granital offers protection from water ingress, proven longevity and UV stable/ fade-free colours. Provides long-term decoration.

Features:

  • Longevity.
  • Moisture vapour permeable.
  • High light reflectivity.
  • Odourless.
  • Environmentally friendly.
  • VOC and solvent free.
  • Chemical crystalline bond.
  • Incombustible.

Surface preparation:

  • All loose, flaking and unstable material must be identified and then thoroughly removed using stiff brushes and broad bladed scrapers to get back to a sound edge; these edges should then be feathered in. Ensure that any paint materials left remaining and the underlying substrate is sound and adhering well. Any gloss or shiny surfaces should be thoroughly flatted down using sand or emery paper to create a good key.
  • Any algae growth should be wire brushed to remove all growths and treated with Keim Algicid, brush applied undiluted and allowed to remain undisturbed for three hours before thoroughly washing off.
  • Any cracks or where there is a need to equalize the surface should be filled using Keim Spachtel, a ready to use silicate mineral filler, brush or trowel applied to a pre-wetted surface and dressed back to the required level.
  • Any new/ repaired surfaces should be left for a minimum period of 15 days prior to any decoration taking place.

Applications:

Masonry repair and paint (painted and unpainted surfaces), and unpainted roughcast coatings.
