Before & After
Render Cleaning FAQ
All surfaces will develop a biofilm over time and some surfaces are more susceptible to its growth this causes damage to the surface overtime and makes it visually un-appealing, or Softwash cleaning treatments can help control its growth, by killing it and slowing down its re-growth.
A Biofilm is a collection of microbial communities enclosed by a matrix of extra cellular substances adhering to natural and man-made surface substrates.
Green Algae – It is a smooth and slimy growth that can show up anywhere there is moisture and partial shade. It thrives in areas with plenty of water and not much direct sunlight, which is why it is often found on north facing walls and other surfaces that are predominately in the shade. It is a large informal group consisting of Chlorophyta & Charophyta
Red Algae – Known as Trentepholia it is part of the Green Algae family and can be found on trees and a wide variety of sub-straights such as Walls, Render & Stonework. It is resistant to sunlight and produces Betacarotene which gives it its red colour.
Black Algae – Known as Aspergillus Niger this Algae will rapidly spread and colonise. It is super resistant and hard to kill, this is because it penetrates the surface of some materials such as stone. It appears as small black dots or blotches. It has a hard outer shell that protects the cells inside. It can often be found on Render, Stonework & Indian Sandstone.
Lichens – May consist of leathery incrustations on the surface or may be embedded in the substrate.
Moss – Typically consisting of green cushion of spike tufts but could also be low and spreading.
Liverworts – Typically leafy, close growing, green coloured plants but some appear as leathery tissue and may resemble lichens.
Mould – Appears as spots or patches which can spread to form a furry layer on the surface, grey, green, brown or black. It can grow within or behind paint causing staining, usually pink or purple, but the mould itself may not be visible. Flaking can occur.
Mildew – Slightly less conceding than Mould it can spread to form a furry layer on a surface, and can be coloured grey, green brown, black or orange.
A biocide is a substance or micro-organism that kills or controls growth of living organisms. Professional use biocides are highly concentrated products thats are restricted to users who undertake appropriate information, instruction and training in line with the recommendations set by the Health and Safety Executive (HSE) (UK). These are used for the control of Algae, Fungi, Lichen, Mildew and Bacteria.
Biocide alternatives – Biocide its self is a cost effective way of controlling biofilm and its growths, however in certain areas biocide is not suitable and there are a range of alternative options we can offer as professional Softwash technicians please enquire for more details.
