Why Standard Plaster Fails in Suffolk, Norfolk & Essex

The most common reason for damp proofing "failure" isn't the DPC injection itself—it's the re-plastering.

Standard gypsum backing plasters (like Browning, Bonding, or Hardwall) are hygroscopic. This means they act like a magnet for moisture. If you apply these to a wall that has suffered from rising damp (and is therefore full of residual salts), the plaster will absorb those salts and pull moisture from the air, causing it to become damp again within months.

The Golden Rule

Never let a general builder re-plaster a damp wall with standard gypsum backing plaster or dot-and-dab plasterboard. It WILL fail. You must use a specialist salt-retardant specification.

Salt-Retardant Render

A dense sand and cement render mix incorporating a waterproofing additive (SBR or integral waterproofer) and a salt-inhibitor is applied to the bare brickwork. This creates a physical barrier that salts cannot migrate through, ensuring the surface remains dry and protected.

Skim Finish

A multi-finish gypsum skim coat is applied to provide a perfectly smooth, glass-like surface ready for decoration. This top coat is purely for aesthetics and gives a professional finish.

Important: Decoration

A short drying period is needed before decorating.

Paint: Normally ready for decoration after 3-5 days. Use a breathable emulsion (mist coat first). Avoid vinyl silk paints as they can trap moisture.
Wallpaper: We recommend waiting a little longer before papering to allow residual moisture in the bricks to evaporate naturally. Your technician will advise on timing.

Preparing a Wall for Replastering

How do you know when a previously damp wall is ready for plastering?

Before replastering, the moisture source should be addressed and any damaged material assessed. The wall may need time to dry, while residual salts can continue to attract moisture and affect ordinary finishes. There is no single drying period that suits every wall; construction, exposure, and the original problem matter. Follow the repair specification and check the substrate rather than covering active damp.
