Primer for concrete before the application of Newton’s range of high performance cementitious waterproofing membranes, levelling compounds, concrete repair and floor coating products.

Description

Newton 903-P is a modified styrene/ acrylic copolymer primer for concrete that is applied prior to the installation of Newton’s range of high performance cementitious waterproofing membranes, levelling compounds, concrete repair and floor coating products, minimizing the risk of out-gassing from both internal and external concrete substrates.

Quick and simple to apply by broom, airless spray, roller or squeegee, it can be applied over new and damp concrete and is soon ready for the application of the Newton membrane above, providing for continuity of work even during the wetter months of the year when most membrane systems cannot be used.

Features and benefits:

  • Quick to apply.
  • Can be applied to damp or wet concrete after heavy rain.
  • Can be applied to new, compacted and prepared concrete of >20 N/mm².
  • Significantly reduces the risk of pin-holing within the cementitious slurry or coating lowering the incidence of outgassing.
  • Very quick curing - the membrane or coating can be applied within 40 minutes at 25°C and within 90 minutes at 5°C.
  • Has a life expectancy of the concrete it is applied to.

Applications:

Primer for concrete before the application of Newton’s range of high performance cementitious waterproofing membranes, levelling compounds, concrete repair and floor coating products.
