PRESERVATION WITH FUNGICIDES
It is a relatively cheap and effective solution. Fungicide sprays are used in order to remove unseen remaining of mould covering the roof tiles, and to slow down the process of growing of new mould.
Thanks to its large ground penetration ability, the fungicide effectively removes and fights mould spores. Active agents of the fungicide stay in the ground and activate in damp conditions, temporarily preventing a new development of bacteria.
An important fact is that the surfaces, from which the fungus has been eliminated, can then be covered with paint or can undergo further treatment.
The waterproofed surfaces have the following features:
- increased dirt resistance
- increased acid rain resistance
- increased algae, moss and lichen resistance
- increased frost resistance
- limited absorption of water, which protects the roof decking from bursting or cracking. The waterproof
treatment process is done by use of aggregate spraying. The waterproof treatment process can be repeated
several times and the resulting layer is water resistant and vapour permeable (hydrophobic).
