The I.P.G’s results start to be visible several months after its installation (about 12 months) and are manifest after 24 months.

In normal conditions, the I.P.G can reduce damp in walls by more than 60% after 24 months.

Improvements become even more noticeable as time goes by, as the issues of damp in walls disappear.

The drying speed depends on the walls’ thickness, composition and coating. Removing the wall’s coating will allow faster natural evaporation as well as good ventilation.

For your restoration work, breathing materials like lime plaster should be preferred for wall paintings, or non-microporous mineral paintings for repairs without sealer.
