Hi Folks, Just a quick one on something that we are coming across a fair bit lately. Wall Cleaning Walls, roughcast renders and pebble dash treatment. The extensive use of rough cast renders and pebble dash on walls has
led to the development of appropriate cleaning techniques. Coloured renders or Monochouche as it’s also known was particularly popular
during the most recent building boom here in Ireland. Although the new build industry has all but
gone these types of plastering are appearing more and more as services such as
External Insulation continue to grow. There’s nothing wrong with these wall coverings, done right they
actually look really well and versus a traditionally plastered then painted
wall I’d choose a coloured render all day long. Like all external surfaces though
it’s only a matter of time before they become dull, discoloured and stained
from growths such as red and green algae or lichen. Trouble is, due to the granular type finish to
render or the easily loosened pebbles on pebble dashing the very last thing you
would want near these surfaces is PRESSURE WASHERS! I recently done a roof repair for a girl whose house was finished in a
bright yellow render, the place was immaculate, you could tell she spent many
hours in the garden and cleaning her home. A little too much as it happened. I
asked what happened to the gable wall where I noticed a section where there was
streaks going in all sorts of directions. Putting her hand to her forehead she
told me that after noticing a red colour appearing on the wall she decided to
try and rinse it off with her little electric pressure washer, big mistake!
Like our Roof Cleaning technique, our treatment of Moss, Algae and
Lichen is soft and safe enough to use on any type of external surface without
any risk of damage to the substrate, and without the use of PRESSURE WASHERS!   |
