K Rend - Pebble Dash Cleaning

What is Softwashing ?
The application of a chemical concentrate via a low pressure nozzle and pump.
How to clean Render Walls
Pressure Washing at a high pressure is not recommended to clean Pebble Dash walls as the force of the jet will dislodge the pebble dash in addition it may score a smooth render finish such as K-Rend. Softwashing is the preferred method for the cleaning of Pebble Dash and Smooth Renders this non-invasive system uses chemicals to remove the staining rather than force. We also use our Super Heated hot water system.

Biofilms form when microorganisms adhere to a surface in a moist environment where the porosity of a surface, its mineral composition, alkalinity and its ability to retain air borne sea salts creates an environment favourable for them to settlement. The biofilm almost always consists of mixtures of many species of bacteria. These microorganisms may cause stone or render to degrade mechanically, chemically and aesthetically. In addition, other species such as algae and lichens can develop rapidly and spoil the appearance of surfaces as they can be very brightly coloured.

Controlling the biofilm
The way of controlling the biofilm is by impregnating the surface with a Softwash solution or to use Super-Heated water at a very low pressure.

System Application
The application to the substrate is by a low pressure pump with the chemical concentrate mixed to the correct solution for the works task. The pressure applied for the spray application is no more than a garden hose around 3.5bar or it can also be applied with a soft bristle brush system. The substrate dictates the application method.
Softwash Biocde: The surfactant in the solution promotes the adhesion of the softwash to the substrate which allows for a prolonged dwell time thus it is extremely effective at low concentration which is safe for people, materials and the environment. It is the oxidization that damages the outer membrane of microbial cells allowing them to be broken up and lifted away from the surface. Biocide: The products works by entering the microorganism’s cell membrane to damage and inhibit the cell’s genetic activity which destroys its integrity. Organic Softwash: The product will enter the cell wall of the surface contaminant killing it.
How Does it Work?
The specialised softwash biocide works extremely rapidly to give remarkable results sometime in only 30-60 minutes – often much less on smooth, non-porous surfaces and does not bio-accumulate also becomes inactive within 30-60 minutes of application where it breaks down when in contact with organic materials and quickly dissipates. Softwash (DDAC) will kill Green Algae within minutes by cell wall puncture and should disappear over a few weeks as with Red Algae - Black Fungi 4 weeks to 6 weeks to shed the dead biofilm. This gives the superficial stains time to recede, leaving the marks if any requiring attention more identifiable. Organic softwash works similar to softwash ddac.
