Coral Gum is a mixture of two components supplied. Remove equal quantities from the tins.Mix and knead for about 20 seconds. When the mass has a uniform colour, and there is no marbled appearance any more, the adhesive is ready for use. A minute remains to use the adhesive, i.e. to affix the mass to the requested position and to fit the coral with its rock substrate in the adhesive. Smooth all transitions with the subsurface.We recommend another minute of curing time. Afterwards the adhesive process isfinished and the Coral Gum is still flexible.Close the lids after use in order to avoid drying.
