Duram Primeseal MC ('Moisture Cure') is a water based, epoxy waterproof membrane.

Duram Primeseal MC is a high performance, versatile, two-part, water based, hydrostatic pressure resistant, waterproofing barrier membrane coating suitable for most types of porous and semi-porous surfaces including green (newly laid) hardened concrete and damp surfaces.

Primeseal MC cures to form a strong, waterproof, hydrostatic pressure resistant and water vapour pressure barrier and is formulated for application on to damp, newly laid concrete and most other construction surfaces.

Primeseal MC can withstand up to 25 metre head of water pressure.

Primeseal MC's versatility makes it also ideal as a primer for waterproofing membranes, paints, industrial coatings and as a bridging coating for normally incompatible coatings.

Primeseal MC's standard colour is light grey but is also available in off-white and black (minimum quantities apply). Primeseal MC has very low VOCs and meets the 'Green Star' enviromental criteria.
