Salt neutralisation and replastering is the internal finish after rising damp, once salty plaster comes off and a salt-resistant system goes back. It is for houses in England, Scotland, and Wales where plaster keeps blistering. It is not a skim over sound plaster. Send the quote form or WhatsApp.
Salt Neutralisation & Replastering
Rising damp carries hygroscopic salts into the plaster. They absorb moisture from room air, so the wall looks damp even after the masonry is drier. Paint over that plaster fails again.
A salt-resistant replastering system, not a standard gypsum skim on the contaminated background. The height follows the salts, not a fixed slogan.
The new plaster has to dry. A vinyl emulsion too soon traps moisture and blows the finish. Breathable emulsion comes first, and only when the wall is ready.
Replastering does not stop groundwater if the course has failed and has not been renewed. It also does not fix rain coming through higher up.
Salt Neutralisation & Replastering
Salts sit where the damp rose and evaporated. That band is the area that comes off, including behind the skirting.
Soft skirtings come off with the plaster. New ones go on after the replaster, not buried in it.
Waterproof paint and gypsum over salts are a common failed repair. They come off back to a sound background.
New plaster can look even in colour while the wall behind is still drying. That is normal and is not a failed course.
A breast holds salts in a thicker mass of masonry. It is included when it is contaminated, not left as a strip of old plaster.
The first coat is a breathable emulsion, and only when the plaster is ready. Vinyl and wallpaper wait.
Replastering starts after the rising damp, or the earlier course, is actually dealt with.

The hack-off follows the salts, including behind skirtings.
Gypsum and waterproof coatings on that band come off.
The new build-up is the one specified for a salty background, not a decorative skim.
A solid brick wall about 230mm thick commonly takes months to dry after the moisture is stopped.
The treatment named in the written quote carries a 30-year guarantee.
Replastering is priced by the metres of wall and the height that comes off, plus skirtings. It is often more than the injection. A quote for “damp proofing” that leaves this off has not priced the finish you can live with.
Questions that decide whether this is the right job.
Not where salts are in it. The salts will mark the skim. That plaster comes off.
The course may be fine and the old salty plaster was left on. The finish fails until that plaster is replaced.
When the wall has dried. On a typical solid brick wall that is months, not the week after plastering.
