Newton 905-CM


  • Can be applied to the surface of System 100 (Newton 103-S and Newton 107F – cement/ acrylic waterproofing membranes) and System 200 (Newton 203-RM – repair mortar)
  • Suitable for freshly placed repair mortars, fairing coatings, cementitious coatings or concrete


A specially formulated, water-based curing compound, utilising advanced acrylic copolymers, that ensures the correct curing of concrete and cement based mortars and coatings.

Sprayed directly over the freshly placed concrete, mortar or coating, Newton 905-CM inhibits the effects of the drying sun and wind to ensure full cement hydration. The product should be used to correctly cure the Newton 103-S and Newton 107F cement/ acrylic waterproofing membranes, and the Newton 203-RM high-strength repair mortar whenever there is a risk of accelerated drying.

Features and benefits:

  • Ready-mixed and ready to apply.
  • A convenient and straightforward alternative to traditional curing aids such as polythene sheeting, damp hessian or sand.
  • A stable product that does not significantly alter the appearance of mortar and concrete.
  • Retains over 85% of the water in the repair mortar during the first 72 hours.
  • Water-based and safe product suitable for use in confined areas.
  • Enhances adhesion when overcoated with Newton specialist coatings.
