Description

Keim Optil is a premium quality, sol-silicate paint specifically formulated for elegant interior applications, giving intense, lightfast colours.

Features:

  • Non-combustible.
  • Vapour permeability in excess of 96%.
  • Provides long-term decoration.
  • Longevity.
  • UV stability/ fade free pigments.
  • High light reflectivity.
  • Odourless.
  • Environmentally friendly.
  • VOC and solvent free.
  • Chemical crystalline bond.
  • Matt finish.
  • 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.
  • All surfaces must be thoroughly washed down with clean cold water to remove all surface dirt and dust.
  • Any cracks or where there is a need to equalise the surface should be filled using Keim Dolomitspachtel, a ready to use silicate mineral filler, brush or trowel applied to a pre-wetted surface and dressed back to the required level. On new surfaces we would suggest that a period of at least 15 days is allowed, prior to the application of Keim Paints.
