Why is an exact calculation important?

Every moisture damage is different - wall thickness, type of masonry and moisture penetration determine how much product is needed to create a complete and effective barrier.
 

❌ Partial treatments (e.g. "only half at first") do not produce any results - the moisture simply moves on and significantly delays the drying process.
 

✅ Our requirements calculator automatically calculates the exact amount you need to ensure that the wall dries completely - permanently, safely and without the risk of mold or rewetting.
