Some building materials have a tendency to deteriorate or rot if they get too wet. An application of lime render will absorb the water before it has a chance to affect the walls, then slowly release it until the render has dried out again. As well as keeping buildings solid, this helps to prevent mould and mildew from growing on walls.

THE COMPETITION. The menâs decathlon consists of ten events that are held on two consecutive days. The first dayâs events include, in order, a 100-meter run, the long jump, shot put, high jump and a 400-meter run. The second dayâs events, in order, include the 110-meter hurdles followed by the discus throw, pole vault, javelin throw and a 1500-meter run. The rules for each event within the decathlon are generally the same as for the individual events themselves, with a few exceptions. Most notably, runners are allowed two false starts instead of one, while competitors receive only three attempts in throwing and jumping events.
