Lichen is the most difficult affective growth to get rid of and grows
foremost on stone, concrete, bricks, slate and eternit. It grows slowly
and the roots get into the surface pores. Lichen is very resistant and
can endure extreme drought during long time.
Lichen consists of one kind of alga and one kind of fungus. The alga
can even survive in dry environments. The fungus gives protection and
fetches water. The alga promotes energy. A typical lichen consists of
fungus tissue and an alga stratum -which is interwoven by the fungus
threads [mycelia]. Below this is the marrow, which is a spongy layer
of fungus hyf. The final part is the "under bark", where the
root sprouts emanates, which attaches the lichen to the surface.
Lichen usually grows on bare surfaces as stone, wood, bark and ground,
but can grow together with moss. Stone living lichen breaks down the
stone to gets access to minerals. Lichen does not break down wood and
other organic materials.
Sexual multiplication happens when fungus spores lands near a suitable
alga. Asexual multiplication happens when lichen parts breaks off and
establishes itself where it lands, through powdery bodies that is distributes
by wind or with water, and through hard outgrowths that are broken off
and spread by animals.
It is not enough to clean or to mechanical remove the affective growth
and assail –the surfaces must be sanitized.
Afterwards the material easily can be maintained and treated –without
risk of new affective growth. Without risks for damages, maintenance
and costs. Without problems. Without affective growth.
Bensaltenside sterilizes all affective growth and disinfects all surfaces
–they become totally clean. Both on the surface and in the pores.
The treatment reaches full effect in 24 hours –then all assails
are killed off. Thereafter the surface is guaranteed to be protected
for a minimum of 4 years.
Repeated treatments –or by mix Bensaltensid in to paint or mortar-
lengthens the protection time with several years.
Outdoors rain gradually removes Bensaltenside – on roofs it takes
about one year and on walls two. You can even clean, brush or rinse
off the remains.
It can not be easier. Not better. Not cheaper.
