Product overview.

Where is it used?

  • Baumit DS26 Flex is used to water proof all plinth areas of EWI systems, both above and below ground.
  • It can be used to waterproof balcony areas prior to tiling.
  • It can also be used around window sill areas in EWI systems to prevent moisture ingress around sills.

How is it used?

  • Baumit DS26 Flex should be slowly added to water, whilst being whisked with a plaster whisk, to form a smooth, lump free slurry. The handling time is around 1 hour.
  • The slurry is applied with a brush, roller or sprayer to a solid, continuous surface. The surface should be free of holes, projections, flaky material, dirt, efflorescence and damp.
  • Once the first coat has dried a second coat can be applied.
  • Baumit DS26 Flex should be fully cured (1-3 days) before soil/gravel is backfilled against the surface or before window sills are installed if used around windows.
  • See data sheet for more detailed information.
Technical Details

How much will you need?

Baumit DS26 Flex has a density of 2.4kg per mm per m² (1mm thickness of plaster over 1m²). Each 20kg bag will cover around 7m² at 1mm thickness which is the thickness required to prevent splash back penetration at plinth level and typically achieved by application of two brushed on slurry coats.

How long does it take to set?

Typically you’ll have around and hour to use the product before it gets too stiff to use. Setting times vary with temperature and humidity but in the summer the product will usually stiffen enough to finish in a few hours and set hard overnight. In winter these times will be extended.

Material in action.

Baumit DS26 Flex is part of the the Baumit PlinthSystem and mainly used to waterproof the plinth areas of external wall insulation systems. It is the layer marked as 6 in this image and is there to keep water away from the plinth insulation boards starting just above ground and finishing below the bottom of the insulation board as shown.

Baumit DS26 Flex can also be used to waterproof other areas of buildings, including retaining walls and also areas beneath window sills within external wall insulation systems.
