Newton 902-P
Application

Priming of damp, non-porous concrete and screed to provide a DPM and vapour barrier, prior to the application of moisture sensitive flooring, coatings, membranes, levelling compounds and screed. Areas of application include:

  • Podium decks.
  • Car parks.
  • Warehousing and storage.
  • Garages.
  • Plant rooms.

Description

Two-part, solvent free, damp tolerable, coloured, epoxy based primer which is applied to non-porous surfaces as a barrier to residual substrate moisture and vapour within concrete and screeds. For porous substrates, Newton 901-P should be applied first to seal the surface and remove the porosity.

The high quality, low viscosity epoxy formulation allows for application onto damp surfaces, allowing for the speedy application of flooring, coatings, membranes, levelling compounds and screeds to damp substrates. Newton 902-P is quick and simple to use and can be applied over cementitious screeds and concrete just seven days after placement. It is applied by brush or roller in two different coloured, gloss coats, or one coat if applied above Newton 901-P - consult manufacturer for details.

Features and benefits:

  • Damp-tolerable.
  • Can be applied to concrete and screed seven days after placement.
  • Solvent free.
  • Provides a good vapour barrier.
  • High-bond damp proof membrane (DPM) that provides a barrier to vapour and to prevent osmotic blistering.
  • Life expectancy is equal to that of the surface it is applied to.

Applications:

Priming of damp, non-porous concrete and screed to provide a DPM and vapour barrier, prior to the application of moisture sensitive flooring, coatings, membranes, levelling compounds and screed. Areas of application include:

  • Podium decks.
  • Car parks.
  • Warehousing and storage.
  • Garages.
  • Plant rooms.

- Suitable substrates:

Indoor or outdoor floors of correctly formed, compacted and prepared:

  • Concrete of at least seven days old.
  • Screed of at least seven days old.
