How does open-pored leather behave in combination with water?
1. Contact with water or moisture should always be avoided.
2. If the naturally left, unsealed leather comes into contact with products containing water, some of the water will be absorbed and cause the leather to swell. Similar to human skin, untreated and natural leather absorbs water as well as moisture. This causes blisters to form in the leather. In the course of time, the leather releases the moisture back into the dry environment, whereby the blisters usually disappear again after 8 - 10 weeks, according to experience.
3. The drying of untreated leather is a critical phase. The leather should be stretched to its desired shape (e.g. by means of a shoe stretcher) until it has regained its strength.
The change in surface texture due to water damage does not constitute a warranty claim.
