Mapei mortars, coatings and paints have been used to complete a façade repair project at Q West – a serviced office and studio complex close to Heathrow airport. Works were completed by specialist civil engineering contractor, Pikehaven Limited, on behalf of Workspace Management Ltd, with Shearwater CBS Ltd providing consultant building surveying advice and Contract Administration. All Mapei products were supplied by Resapol, Park Royal.
Fronting Great West Road in Brentford – outside London’s congestion zone – Q West provides space for both blue chip companies and small enterprises, alongside a mix of additional facilities and services. The recent façade project included the repair of external concrete and split, weathered Asphalt across the ground floor elevation of the 1960’s building; application of anti-carbonation coating and final finishes.
During the repair phase, Mapefer 1K anti-corrosion cementitious mortar was applied over steel reinforcement rods. Two shrinkage compensated repair mortars were specified to repair and smooth surfaces: Mapemortar HB R3 was used as the main replacement of concrete and rapid-setting Planitop Smooth & Repair R4 – a thixotropic, fibre-reinforced cementitious mortar – was applied to areas below 10mm for smoothing out. This was followed by application of Elastocolor Paint – a protective and decorative elastomeric, anti-carbonation coating, with crack bridging protection. Malech – a water-based acrylic undercoat and bonded primer – was then applied to create a smooth finish.
Repair of the Asphalt surface was carried out using Purtop Easy coloured waterproof polyurethane resin and Mapeflex MS45 – a painted hybrid sealant and adhesive used to seal and bond the surface.
