After a wet autumn and winter, moss or green deposits settle on your roof, your walls and your terrace... The arrival of the good weather is the ideal moment to eliminate these deposits, greens and lichens.

The main active ingredient used in this Bionetal express defoamer is of mineral origin : sodium hydroxide. It acts by contact and deteriorates the waxy layer protecting the foliage of the plants, causing a browning and a destruction of the treated surfaces.

This deposit destroyer can be applied on many surfaces such as stone, brick, concrete, fibro-cement, clay tiles, plaster and slate.

Perfect against deposits and clogging of buildings, houses, roofs, terraces, facades and walls, tombstones, historical monuments, glass roofs, stairs, paving stones, pool coping, statues, interlocking paving stones, wood, glass, tarpaulins, PVC etc..

It will be able to act just as effectively on the red marks of the frontages or the saltpetre of old walls.

Its effectiveness is visible very quickly: the green deposits start to yellow as of 1 hour after the application (for a not diluted use). The formula is acid-free and free of harmful chemical molecules (such as Quaternary Ammonium ions, chlorine or bleach) and is highly concentrated in active ingredients of 100% natural origin. 

The product remains active even in case of rain after 6 hours (for undiluted use). It acts even on thick and abundant green deposits (with undiluted use).

In roof treatment, rainwater recovery is possible for watering or reuse in sanitary facilities (up to 3% of pure product compared to the volume of the tank).

Finally, it is an economical product. Used pure for a quick effect, its yield is 10m²/liter. Diluted to 50% (on thin green deposits and in dry weather), you can treat up to 20m²/liter.

Use on red marks of frontages
On the red traces, we advise you to well sprinkle the walls (1 liter for 5 to 8 m ²), to let act 24 hours then to proceed to a brushing (using a brush soaked regularly in water to make foam) then to rinse with the average jet (not of high pressure). A veil may remain, this should fade with time.

Use on wood
