Bostik understands that flooring installers need to suppress moisture as quickly as possible before applying primer, self-levelling underlay, repair patches and floor coverings. This is especially true with commercial project work in retail outlets, hospitals and schools, where installation deadlines are critical. That is why our moisture vapour barrier coating systems have fast cure rates that accelerate the construction process, allowing the application of a full flooring preparation system faster than ever before.

Moisture vapour barrier coatings: Smart innovations

Bostik's moisture vapour barrier coating solutions offer many benefits, saving you time and providing flexibility across a wide range of installation projects. Our mosture vapour barrier coatings allow for the surface of the substrate to be adequately primed prior to the application of a waterproofing membrane. This will prevent water seepage and permeation in building and construction substrates as well as prevent the formation of mould and bad odours.


  • Faster cure rate: enabling floor covering to be installed earlier in construction projects
  • Moisture mitigation: extremely good resistance to residual moisture vapour, up to 100% relative humidity (RH)
  • Versatility: suitable for all kinds of project work, from hospitals and schools to commercial and residential buildings
  • Professional grade: special additives provide excellent adhesion properties and one-coat systems
