Smart moisture barrier for subfloor preparation

Bostik vapor barrier membranes provide essential moisture mitigation and suppression for subfloors.

Fast-tracking floor preparation

We understand that flooring installers need to supress moisture as quickly as possible before applying primer, smoothing compound and floor coverings. This is especially true with project work in hospitals and schools, where installation deadlines get ever tighter.

That’s why our vapor barrier systems have fast cure rates that accelerate the construction process, allowing the application of a full flooring preparation system faster than ever before.

Moisture barrier: smart benefits

Our moisture barrier products, in addition to our moisture mitigation products, offer many complimentary benefits, saving you time and providing flexibility across a wide range of installation projects:

  • Faster cure rate: enabling floor covering to be installed earlier in construction projects
  • Moisture mitigation: extremely good resistance to residual moisture vapor, up to 100% relative humidity (RH)
  • Flexibility: Bostik damp proof membranes can be used on all concrete and gypsum-based subfloors, including power floated slab and cement screed
  • Versatility: suitable for all kinds of project work, from hospitals and schools to commercial and domestic buildings
  • Professional grade: special additives provide excellent adhesion properties and one-coat systems



A broad range of barrier systems

Bostik provides a large portfolio of different moisture vapor barrier systems, water barrier systems and even radon barrier systems. Our product range covers a broad range of challenging construction installations, including instances where water pressure exists due to water table presence just below the slab or subfloor
