Rubber Patching and Waterproofing.
Capt. Paul Boyton, the famous aquatic voyager in his rubber suit, has furnished us two practical suggestions in regard to patching rubber boots, coats, etc., and also to waterproof sails, tents, awnings, and similar fabrics.
To Patch a Rubber Boot or Garment.
Take a piece of sand-paper and roughen the edges of the break as far around as the size of the patch. Next apply rubber cement to the roughened surface, and at the same time cement a piece of rubber cloth or cloth well coated with the cement. Let both remain for four hours in a place free from dust. Then put on another thin coat of cement and let them lay for about two hours. Next place the patch carefully over the break and hammer well together. Let stand for a few hours and the place will be as strong and tight as ever. Be sure the patch and the article to be patched are perfectly dry before applying the cement.
Pure natural rubber or rubber cement can be obtained at any rubber store, also prepared patch cloth.
To Make Rubber Cement.
Take half a pound of pure natural rubber, cut it into small pieces, and dissolve it in a sufficient quantity of 100 proof naptha. It will take from two to three days to dissolve properly.
To Waterproof Canvas or Cloth.
Take one pound of yellow paraffine wax and dissolve in one quart of benzine. Apply with a brush.
