The specification for the main roof included for an application of a biocidal wash and power wash followed by an embedment coat of the liquid applied one part air cured Decothane incorporating Reemat Premium followed by a further coat of Decothane in a contrasting colour. Upstands were coated using the Decothane Detail Coat.
Vertical surfaces were terminated by either termination bars or sealant beneath the existing cladding and lighting conductors tapes refixed using self-adhesive clips. The paving slabs and pebbles around the plant room were reinstated on a Filtration Layer to assist in drainage in these areas.
The insulation was also replaced on one of the small roofs prior to the application of the Decothane coatings using a Sika LPL Vapour Control Layer, 130mm thick Decotherm Insulation Board and self-adhesive Carrier Membrane.
In total 2,000 litres of Decothane products were applied successfully with Sika LPL issuing a 15 year guarantee for the client.
