Thorough substrate preparation is essential.
All necessary repair work should be carried out prior to application of the coating and the prepared surface should be clean, sound and free of flaking or loose material, moss or fungal growth. The surface may be damp but NOT WET.
Due to the wide variation in roofing materials and conditions, the following are generalised recommendations only. Please contact the Polycote technical helpline if more specific guidance is required for your application.
Moss, lichen and fungal growth – remove by stiff broom or jet washing, then treat the area with Polycote Destroy IT to inhibit further growth – see the relevant data sheet.
Porous surfaces – seal first with Polycote Roof Primer – see the relevant Data Sheet.
Asphalt, bitumen and felt roofs – remove all chippings. Blisters in asphalt can generally be left in place. Blisters in felt should be cross cut, opened up and re-fixed using Wetterflex BG – see relevant Data Sheet. New asphalt and bitumen surfaces should be allowed to weather prior to application.
Metal surfaces – remove all loose and flaking rust and treat with Polycote Rustex – refer to the relevant data sheet.
New galvanised steel should be allowed to weather, or may be treated with a suitable primer – please contact the Polycote technical helpline.
Gaps, cracks, joints and holes – Poloflex PG will fill or bridge small cracks up to approximately 1-2mm wide.
The use of Polycote Flexible Membrane is recommended – see 'Application'. Wide cracks or joints should be raked clean, opened out and filled using Wetterflex TG (Trowel Grade) followed by the Flexible Membrane procedure.

Stir well before use.
Having fully prepared the surface, first fill all gaps, cracks, joints and holes with Poloflex PG, or Wetterflex TG if wider than 3mm.
Polycote Flexible Membrane should be used to reinforce repairs over any cracks or joints that are subject to movement.
The membrane should be cut to approximately 100mm wide strips of appropriate length and laid into the wet coating over the cracks immediately, stippling with a paintbrush to integrate the membrane into the coating. After all necessary membranes are embedded, an overall coating may be applied by brush. If this is done immediately, care should be taken when over-coating the placed membranes to avoid disturbing them.
If possible, allow overnight setting of the embedded membranes before over-coating the entire roof surface. If a second coat is required, this should be applied at right angles to the first.
Polycote Flexible Membrane may be laid into the entire surface of the wet first coat to reinforce the system. This is then covered and encapsulated by the second coat.
Poloflex PG may alternatively be spray applied (material density SG approx. 1.2 @ 25oC).
