Each pack contains one tin of curing agent, one tin of resin and a blended aggregate. Thoroughly mix the two liquid parts together before tipping the mixed components into the blended aggregate. The best mix can be achieved quickly by wearing disposable gloves and kneading the mixture by hand.
Once mixed, the product is trowelled firmly against the surface to be repaired and finished with a steel trowel or float. To prevent trowel marks, a rag moistened with white spirit may be wiped across the face of the tool.
