What is Softwashing ?
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.
K Rend Pebble Dash
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.
Biofilms
The accumulation of the microorganisms that give the effects in the pictures below may take years to accumulate but if left unchecked is aesthetically unpleasant and may damage the surface render
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. (rarely used)
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 and level of contamination dictates the application method.
Softwash Biocde Na: 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. Softwash Biocide DDAC: 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.

Render Cleaning Results

Stone Cleaning Brick Cleaning

Sandstone Cleaning Brick Cleaning
Outstanding results can be achieved by cleaning stone or brick with softwash systems as can be seen in the pictures below. We also are able to clean stone or brick with our super- heated hot wash system which operates at pressure around 500psi and temperatures of 120 degrees.
biofilm Biofilm
Biofilms can accumulate on any of the property walls but it is more likely, on the walls that take the brunt of the weather. Usually a front elevation and a gable or the rear elevation and a gable however due to the changes in building regulations for thermal insulation and wetter climate any wall of the property could be affected. This contamination is unsightly but may cause damage to the render so cleaning of the render is esssential. Render Cleaning is by Softwashing which is a chemical system that is gentle sprayed or brushed on the wall depending on the system used can rapidly clean red/black/green wall staining giving remarkable results. Residual protection to the render is given by applying an inhibitor treatment to the render after rinsing is complete. The process normally takes one day to complete but this will depend on wall contamination and property size. Quotes can be obtained Free of charge by calling us or filling out the online forms.

The Chemical: 1) A hypochlorite based softwash biocide which at 5:1-10:1 dilution is classed by the EU, PCD and HSE as non-corrosive or hazardous to people or the environment 2) A Biocidal Wash (DDAC) fully biodegradable does not bio-accumulate Ph neutral, so safe for children and pets once treated surface is completely dry. 3) A organic Softwash which is biodegradable100% safe for the environment 100% Hypochlorite) Free 100% Biocide Free Non-hazardous Nontoxic.
The results in the above photos were obtainable in I day but this is dependent on the substrate and the system used. 1) Softwash Biocide: 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. (2 x treatments and 1 biofilm inhibitor treatment) 2) 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. (1x Treatment may require second treatment at a later stage depending on contamination level) 3) Organic softwash: Works similar to (softwash ddac) organic Softwash is biodegradable100% safe for the environment 100% Hypochlorite) Free 100% Biocide Free Non-hazardous Nontoxic. (1x Treatment may require second treatment at a later stage depending on contamination level)
Case Study The property above was set in a rural location with it fair share of wet and windy weather. We were asked to clean the K-Rend prior to the property sale. The task was accomplished by using Sofwash Biocide and an application of the biofilm inhibitor. The Softwash biocide was applied using the spray application system. We applied the first treatment of the Softwash biocide waited 30-60 minutes before rinsing with water then applied the second treatment and waited again approximately 60 minutes before rinsing. The works were completed with the application of the Softwash (ddac) biofilm inhibitor. The works took 1 day to complete.
