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.

This powerful soft wash biocide rapidly cleans black, red, green, and orange staining from render, paths, upvc, cladding and roofs.
Blackwash is suitable for cleaning coloured render as it doesn't damage the surface, while giving fast, impressive results. Blackwash
is manufactured to the highest possible quality and safety standards. The active ingredient at the level of concentration used in
Blackwash is recommend for cleaning the products of industry-leading companies such as K-Rend, Weber and Kingspan Cladding.
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.
AlgoClear will clean the render over a few weeks eliminating those unsightly algae, moss and mould stains without harming the K-
Rend returning it to that new look again.

OUTSTANDING RESULTS from BLACKWASH
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.
