  • Surfaces should be clean, dry, frost free and free from dust, grease, loose material and other contaminants

  • For timber and composite boards the surface must be sound and not be degraded.

  • An effective vapour or damp membrane should be incorporated in the roof structure especially where the roof is insulated. Effective roof venting should be provided to ensure that condensation and trapped moisture are allowed to escape.


  • Applied using a medium pile roller to achieve to an approximate coverage rate of 3-4m² / litre. A larger quantity of adhesive is necessary for open texture and rough surfaces.

  • The adhesive has a long effective open time, ranging from approx. 5 to 15 minutes after application assuming average UK weather conditions. The roof sheet should be laid into the adhesive during this period and pressed firmly into the adhesive with a broom or roller.

  • The effective open time range will be reduced by higher temperatures in the summer months. Care should be taken to ensure the membrane is laid into the adhesive before membrane grabs.

  • Regular checks should be made to ensure the adhesive completely transfers to the reverse of the sheet and is bedded in place after consolidating. The roof sheet should be pressed into the wet adhesive to ensure full adhesion, smooth membrane and remove any trapped air.
