Natural Exterior Cleaning


OutCide's soft wash cleaning system is suitable for all kinds of wall finishes including; natural stone, brick, napped plaster, roughcast render, pebbledash, timber cladding and aluminium siding.

This safe and modern treatment is highly effective against biological growth like moss, algae and cyanobacteria, fungi, lichen, and the common red algae contamination seen on plastered walls across Galway and Mayo.

To clean your walls we apply Algoclear® Pro Softwash (Professional Use Only) using a high-reach pole & brush system from the ground level. Unlike traditional high pressure power washing jets, the soft wash system prevents any damage caused to the wall surface or existing paintwork, and is an essential treatment before the application of new paint to prevent further growth.

Designed for weather conditions in Ireland, Algoclear® Pro Softwash kills the moss, algae, fungi and lichen within 2 hours of application and the cleaning process starts to act immediately, with visible results sometimes as soon as 24 hours.

The biocide chemical solution kills the actual biological growth, and the weather cycles of rain and sun continue to clean the remainder of the material from the wall surface over the next couple of months. The cleaning timeframe varies from surface to surface and the severity of the weather, but cleaning is normally complete within a year and the cleaning process will continue for up to two years.
