<p>Stick-on protective film for part of interior of toiler bowl is coated on one side with a water-insoluble adhesive which adheres firmly to very smooth material, and on the other side with chemical substances providing a smooth slip surface to which no other materials can adhere and can be removed by short flushing with water. The film remains soft, adapting itself precisely to the shape of the bowl, and the coating may be applied by heating, e.g. coating with "Teflon". The material of the film itself is rigid, allowing it to be pressed onto and to grip the bowl.</p> |
