Fungal attack averted despite unauthorised treatment
With the help of ProtoxSvampPro has succeeded in preventing new fungal infestations in a listed garden house in Museumshaven in Christiansfeld. The remarkable thing about the project is that it was not carried out in the correct craftsmanship manner; in short, they jumped the gun to save money.
After removing the affected joists in the garden house floor and a window lintel, the masonry was brushed to remove loose fungal mycelium. The masonry and abutments were then saturated with ProtoxSvampPro. In addition, a new, untreated window lintel was installed as a control.

Three years after the repair, an inspection in early summer 2007 showed that no new infestations of true mould had occurred.

Normally, it is costly to fight Dry Rot because you have to be thorough. If you wanted to do it by the book, you should have done it that way:
All masonry is cleaned of loose plaster, joints are scraped out and half of the prescribed amount of fungicide is applied. The masonry is then grouted or taped and the other half of the fungicide is applied. New woodwork laid into masonry must be pressure impregnated (class A or equivalent) and all wooden cut surfaces must be saturated with an approved fungicide.
