Class R4 Approved

Class R4 (EN 1504-3) high strength high build repair mortars are suitable for interior and exterior surfaces with mortar possessing high mechanical structural performance requirements. These fibre-reinforced, shrinkage compensated thixotropic mortars are ideal for precast structures, canal linings, hydraulic works, and tunnels that require resistance to sulphate attack. Many of the R4 concrete repair mortars we supply are suitable for the repair and reconstruction of concrete coverings damaged by rusted and corroded re-bars.

Promain also offer paint solutions such as Rust-Oleum Noxyde or Fosroc Galvafroid both suitable for coating re-bars before the application of  a concrete repair mortar. Class R4 of BS EN 1504-3 is ideal for the filling of rigid joints between base and column, cracks in floors and joints between walls etc.

If required, these products can be painted over with a range of paints. Paints such as Sikagard® 550W an Elastic Crack Bridging Masonry Paint (Formerly Decadex). This is an anti-carbonation wall paint designed to be water permeable and offers excellent resistance against harsh elements and is ideally suited for multi-story car parks.

Alternatively, we have colour washes which help with ‘invisible’ repairs where a natural concrete finish is required.  Available as single bags, or we can offer half pallet or full pallet offering bulk discounts. If you have any specific project requirements, please contact our team where we will be happy to assist.
