Application

Suitable for the pre-priming of damp or porous concrete and screed prior to the application of Epoxy Primer.


Areas of application for Epoxy Primer include:

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

Description

Two-part, solvent-free and clear epoxy which is applied to damp and porous surfaces as a pre-primer prior to the application of Newton Epoxy DPM, 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 Epoxy Primer is quick and simple to apply by brush or roller and can be applied over cementitious screeds and concrete just 7 days after placement.


Features and benefits:

  • Very damp-tolerable.
  • Can be applied to concrete and screed seven days after placement.
  • Low viscosity.
  • Solvent free.
  • Provides an excellent 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.


Suitable substrates:

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

  • Concrete, at least seven days old;
  • Screed, at least seven days old.
