Waterproofing slurry - Baumit DS26 Flex render


Baumit DS26 Flex is:-

  • a cement based waterproofing render.
  • waterproof, vapour permeable, flexible and frost resistant.
  • suitable for application with brushes, rollers or trowels.

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.

How much will you need?

Each 20kg bag will cover around 7m2 at 1mm thickness. This is the thickness required to prevent splash back penetration at plinth level.

This product comes in 20kg bags or pallets of 48 bags
