| Hypatuffa |
The following method can be used for covering old, glazed, kitchen sinks to make alpine or miniature gardens.
Preparation;
Clean the sinks thoroughly, chip the glaze on the exterior of the sink, then coat the surfaces to be covered with hypatuffa with a p.v.a. bonding agent to ensure good adhesion.
The mix;
Measure out 2 parts (by volume) sifted sphagnum moss peat, 1 part coarse sand, and 1 part cement.
Then mix the ingredients thoroughly whilst dry then add water.
Mix thoroughly until the mixture is of a consistency that can be cast into blocks.
Application;
Trowel the tuffa mix onto the sides of the sink after the p.v.a. has dried.
The surface can be textured to your own requirements, e.g. smooth, scalloped, or serrated/scratched, the choice is yours.
An alternative use; is if you require stones to make a rockery then make irregular shaped blocks to replicate natural rock formations.
And if necessary and before the blocks set, form fissures in the blocks / stones and later embed tiny rockery plants in them.
