Suggested use
Use in conjunction with multi directional roving to construct glass reinforced laminate and repair severely corroded
and pitted areas or to offer additional protection in the corners of tankage prior to spray application. See Corrocoat Data Sheets TC1.
Health & safety
Before commencing work, read the product Health & Safety data sheet. Only to be used by adequately trained personnel.
Surface preparation

Overcoating
May take place as soon as the previous coat has gelled and while still tacky. Maximum overcoating time 72 hours at 68°F (20°C). Once the maximum overcoating time has been reached, the
adhesion values attained by any subsequent coat will reduce dramatically. It is important to observe maximum overcoating times and note these will vary with climatic conditions. Any further application of coating at this juncture should be treated as a repair, with the surface flashed over to provide a physical key. Styrene cannot be used to reactivate the surface and may in some cases impair adhesion.
