Algotech

Sprayed coating to clean and protect natural stone surfaces from algae and moss.
ALGOTECH is an organic apply and forget algae and moss cleaner ideal for cleaning down natural stone, masonry and other common substrates.
Environmentally-friendly Algotech kills algae and moss in days and prevents further growth. It can be spray or brush applied to large expanses of masonry or paving as part of refurbishment or maintenance work.
Algotech s advanced formula contains a combination of chemicals which prevents the process of photosynthesis, causing algae to die back after just a few days. However, Algotech is harmless to animals and pets, together with most forms of more complex plant life.
It works by forming a chemical shield against the light to kill off green algae, which, because the organisms are so minute, then disperses and disappears. Algotech, then prevents regrowth until the invisible residue is cleared naturally over time by rainfall.
Algotech can be applied at any point in the refurbishment process, either during works or as part of final cleaning down. It can also be used to clean roof slates, tarmacadam, concrete surfaces, fencing and many other substrates susceptible to algae growth.
In most cases, algae will be eradicated after a single application, although two coats may be necessary for more concentrated areas of growth and for more stubborn types of moss or lichen.
