Thorough substrate preparation is essential.
The repair area should be clean, sound and free of flaking or loose material, moss or fungal growth should be treated with Polycote Destroy It to inhibit further growth. Metal surfaces should be free of loose and flaking rust. Cracks and joints wider than 3mm should be raked clean and opened out prior to filling with Wetterflex TG.
Stir before use.
Having prepared the surface, apply Wetterflex TG using a trowel.
Joints and cracks should be filled slightly proud of the surrounding area and thinly overlapping the sides. 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 cracks immediately, stippling with a paintbrush to integrate the membrane into the wet 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 applying the second coat, making sure to completely cover the membrane.
