After mould and damp — repainting and renovating
It’s done. The remedial damp-proof course has been installed. Or maybe you’ve upgraded the ventilation system. Whether you’re dealing with mould as a result of condensation issues or rising damp, it’s a big weight off your mind to have the underlying causes of dampness fixed. But the job isn’t done yet.
Winter is definitely here and with it comes the annual increase in damp and mould problems. In this week’s edition of Built to Protect, we’re examining a selection of the post-repair works that may need to be done once the underlying causes of damp have been fixed.
Whether you’re dealing with a mould scarred wall or looking for the right plaster for the job once a remedial DPC has been installed, we’ve got you covered.
Repainting after mould treatment
Black mould can compromise wallpaper and ruin painted surfaces. In extreme cases of heavy mould growth, once you’ve cleaned away the stain and applied a sanitiser like the Dryzone Damp and Mould Removal and Prevention Kit , some faded stain may remain on porous substrates like wallpaper or plaster.
Refresh your walls and ensure that mould does not grow again with Dryzone Mould-Resistant Emulsion Paint . While solving the underlying issue should always be the priority, Dryzone Mould-Resistant Emulsion Paint provides a final preventative barrier for kitchen and bathroom walls and ceilings at risk of mould growth.?
The powerful Dryzone formula prevents black mould growth for up to 5 years after 2 coats. Dryzone Mould-Resistant Emulsion Paint is compatible with all known undercoat paint finishes and is available in Brilliant White and Magnolia colours. Apply like a standard decorative emulsion paint.
Got a unique colour in mind? Use Dryzone Anti-Mould Additive to any decorative paint for anti-mould protection.
Replastering after a rising damp treatment
Tackling rising damp is always a big job. Once a damp-proof course has been established and rising damp has been stopped, the slow and steady drying-out process begins.?
When a damp wall dries out, the groundwater evaporates to leave behind hygroscopic salts. This salt then migrates to the surface to cause decorative spoiling like crystallisation and damp patches.
Gypsum plaster may be easy to prepare and quick to apply, but it will soak up moisture inside the wall. Hygroscopic salts break down gypsum plaster, causing it to crumble and blister.
When you need to replaster walls after an effective rising damp treatment, the Dryzone Renovation Plaster Range has all you need to control salt migration while allowing walls to thoroughly dry out.
Dryzone Damp-Resistant Plaster is a breathable and pre-blended plaster for the control of damp and salt migration. Its porous structure allows damp walls to dry out while holding back hygroscopic salts.

Dryzone Damp-Resistant Plaster Fast-Set Formula provides the same excellent salt resistance and breathability in a quick-setting formulation. The optimum choice for dubbing out smaller areas or time-sensitive projects.?
For traditional and heritage buildings, Dryzone Hi-Lime Renovation Plaster is a natural hydraulic lime and calcite blend that protects against salt migration while providing high breathability and high plasticity.
Once cured, apply Dryzone Hi-Lime Finishing Plaster or a standard gypsum skim coat atop. Dryzone Mould-Resistant Emulsion Paint or paint mixed with Dryzone Anti-Mould Additive can also be applied for that extra layer of assurance.
