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, epoxy based primer which is above Newton 901-P pre-primer as a barrier to residual substrate moisture and vapour within concrete and screeds.

The high quality, low viscosity, epoxy formulation of the combined application of the primer and pre-primer is suitable 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 7 days after placement.

It is applied by brush or roller in one coat and is a key component of the Newton NewSeal Flooring System for the sealing, coating and protection of exposed screed and concrete surfaces.

Features and benefits:

  • Very damp-tolerable.
  • Can be applied to concrete and screed seven days after placement.
  • Solvent free.
  • Excellent vapour barrier.
  • High-bond DPM that provides a barrier to vapour and prevents osmotic blistering.
  • Life expectancy is equal to that of the surface it is applied to.

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.
