Newton 901-P
Application

Pre-priming of damp or porous concrete and screed prior to the application of Newton 902-P primer. Areas of application include:

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

Description

Two-part, solvent free, clear epoxy which is applied to damp and porous surfaces as a pre-primer prior to the application of Newton 902-P, a vapour barrier and primer for newly placed, or damp, concrete and screed.

The high quality epoxy formulation allows for application onto damp surfaces, whilst the low-viscosity penetrates deep into porous substrates to effectively seal the surface ready for the main primer application.

Newton 901-P is quick and simple to apply by brush, roller or squeegee, and can be applied over cementitious screeds and concrete just seven days after placement, and is a key component of the Newton NewSeal System for the sealing, coating and protection of exposed screed and concrete surfaces - consult manufacturer for further details.

Features and benefits:

  • Very damp-tolerable.
  • Can be applied to concrete and screed seven days after placement.
  • Low viscosity.
  • 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:

Pre-priming of damp or porous concrete and screed prior to the application of Newton 902-P primer. 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, at least seven days old.
  • Screed, at least seven days old.
