Koster 21 is a two-component, solvent-free, multiple use crack bridging waterproofing coating from Delta Membrane Systems.

  • elastic, crack-bridging waterproofing material

Being liquid applied – it creates a seamless coating around difficult or complicated detailing.

Applied in two coats by brush, roller, trowel or other customary masons’ tools.

It is suitable for internal or external application, and has a white finish that reflects sunlight and reduces building surface temperatures.

  • supplied in 20kg containers which gives a coverage of about 6 to 8m2
  • resistance to occasional foot traffic, aging, hydrolysis, frost and salt
  • seals against synthetic oils and aliphatic hydrocarbons with high boiling points

Koster 21 is for the positive side waterproofing of basements, concrete slabs, in tanks, on flat roofs, underneath tiles, on terraces or balconies, and similar applications.

It bonds well to a wide variety of substrates, including: masonry, concrete, screed, PVC, metal, and bitumen.
