Newton Epoxy Top Coat

Newton CDM 508 is a high quality cavity drain waterproofing membrane, supplied in a number of sizes and in 500g/m2 and 700g/m2 variants for use within the Newton CDM System, our internally applied waterproofing system that also includes drainage and pumping systems.

CDM 508 is suitable for waterproofing earth retained walls and vaulted soffits and floors. It is guaranteed against deterioration for 30 years, with a life expectancy of the design life of the building (DIN 9001:2000), and supported by BBA Agrément Certificate 22/6357.

CDM 508 is inert and non-polluting to drinking water, highly resistant to water, alkalines, saline solutions and organic acids, and not affected by minerals and hydrocarbons. It is also rot-proof, and resistant to bacteria, fungi and small organisms.

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.

Newton CDM BaseDrain and CDM FloorDrain is the drainage system used most commonly within the Newton CDM System − A range of products that collectively receive water ingressing at weaknesses within the structure and then discharge the collected water to a Newton Basement Pumping System or safe drainage.

The 18 mm holes drilled in both sides of the profile, as well as to the top surface, allows water from beneath the CDM Fibran XPS-500C insulation boards and within the spacer zone to enter the drainage channels more easily.
