A fresh layer of rubber may be attached to the soles of a pair of rubber sandshoes in the following manner. Put the shoe on a last, and rasp the old sole all over till it is quite clean and rough. The new sole must also be treated in the same way, and the dirt and dust brushed out. Now give both the old and new soles a coat of very thin solution, and when dry give another coat (or two if required) of slightly thicker solution. When tacky, heat both the sole and the bottom of the shoe, so that the spirit left in may evaporate; then place the two together, drawing the sole a shade tighter, so as to give it a little tension.
