Rizistal TC200 and TC210 Tack Coat Primers are recommended on dry and damp surfaces respectively, where there is concern regarding the quality of the concrete, metal or other substrate being repaired.
Excellent adhesive bond between Rizistal RM Products and an existing weak, porous or friable substrate.
Excellent penetrative qualities to porous substrates improving its strength.
An effective bonding layer over damp cementitious substrates, which penetrates the substrate capillaries prior to cure, blocking further moisture migration.
Break away all loose or friable material from the repair area with hammer and chisel or similar. Surfaces should be clean, dry and free of contaminants. Wire brushing, disc grinding or sweeping is generally sufficient.
Remove any loose, flaking or friable material and rust by wire brushing or angle grinding with suitable grinding disc or wire brush. Oil or grease should be removed with Rizistal Safer Solvent and the metal allowed to dry. Epoxy Tack Coat Primer should be applied immediately after cleaning and drying, before flash rusting reoccurs.
25 minutes maximum at 20°C when decanted into a shallow tray. Higher temperatures will reduce the working time. If the material is used past these times it will become difficult to use and adhesion will be reduced.
Will be sufficiently tacky to overlay after approx 50 to 60 minutes at 15°C to 20°C. This will be extended to 3 to 5 hours at 0°C to 5°C.
Overlaying must be completed before the Epoxy Tack Coat Primer cures hard. If it is allowed to harden another coat must be brushed over the surface, if possible within 12 hours.
Should be applied as a thick layer covering all of the damaged substrate.
When fully cured, acid and alkali detergents or degreasers may be used to clean the surface. Always follow manufacturer recommendations.
