Frequently Asked Questions

The most effective treatment depends on the cause and severity of the salt contamination.

In many cases, a new damp-proof course (such as DPC injection cream) is installed to stop ongoing moisture movement. This is often combined with removal of salt-contaminated plaster and replacement with a salt-resistant replastering system.

Simply painting over the damage will not solve the issue, as the salts remain active within the wall.

A proper treatment plan addresses both the moisture source and the salt contamination.

In most cases, yes.

When salts have contaminated plaster, they continue attracting moisture even after the wall dries. This causes recurring bubbling, flaking, and paint failure.

Replastering removes the contaminated material and replaces it with a salt-resistant render system designed to prevent future breakdown.

Without removing salt-affected plaster, surface repairs usually fail.

Treatment time depends on the size of the affected area and the method used.

Installing a damp-proof course is usually completed in a day for most residential walls. Replastering and drying time will extend the process, as new render needs time to cure properly before painting.

While the installation itself is relatively quick, full cosmetic restoration takes longer due to drying and finishing stages.

A professional assessment provides a clearer timeframe based on your specific property.
