I've just had an estimate for repair of my cracked pebble dash external wall and it includes a final coating of Murfill waterproof water dispersed polymer solution. My son has warned that if water gets in anywhere through a crack it will be trapped and will cause problems. What's the general consensus about waterproof coatings for rendered walls? I suspect the low temperatures last winter has caused the damage to my wall.
