Coloured render is now popular on many new builds however the introduction of wall insulation has reduced heat transfer through the wall which means a moister render and more algal growth. Published studies show that a temperature decrease of 2 degrees Kelvin leads to increasing the relative humidity of the render by approximately 10%. Cotec’s surfactant cleaner is a fast-acting solution that rapidly removes 98-100% of all staining from pebble dash rendered finish.  The treatment is applied to the wall using a low pressure spray unit that mixes the chemicals before the application to achieve outstanding results and as a part of the process a telescopic lance is used thus no need for scaffold etc. at an additional cost. It is dependent on the wall contamination but usually green stains will disappear within an hour, red will turn orange and disappear in 1 hour. Black stains will normally disappear within 1-2 hours after second treatment.

Controlling the biofilm Render Cleaning

The way of controlling the biofilm is by impregnating the surface with a solution of  AlgoClear® Pro which works on the biofilm by puncturing microorganisms cell walls. It does not interact with the mineral components of self finished renders and does not contain any compound deleterious to the colouring agents or the surface cohesion. In particular, the product has a neutral pH. On porous render, the surfactant active will decontaminate deep into the surface porosity by capillary action. Green and red Algae will die within minutes of the application. If the algal film is thick enough, a milky sheen will replace it for a short period, before dispersing. The orange pigment originating from the red algae Trentepholia may dwell in the surface porosity, but being water soluble will wash with the rinse. Bacteria and Cyanobacteria have thin cell walls and die at rates varying with the concentration of the Algoclear solution. At a normal rate all studied species die within one hour. The self cleansing process takes a few days in normal exposure. Moulds are a group of filamentous fungi. Their structure enable them to key their filaments in the porosity of render and even rock. As a result, moulds do not self cleanse as readily as algae. The most common species of fungi on façades are the Cladosporium spp and Alternaria spp. Both metabolise a black pigment protecting them from UV radiations, and causing some staining of the surface. Moulds are killed by a solution of Algoclear within approximately one hour.
