Hybrid Plasterboard Damp-proofing System
What is the Dryzone Express Replastering System?
|Standards & Accreditations|
The Dryzone Express Replastering System combines the power of our patented Dryzone Damp-Proofing Cream with a modern fast-track replastering system. It was created with the following design criteria:
- As effective as sand:cement
- Faster than sand:cement
- Cleaner than sand:cement
- Warmer surface than sand:cement
- Less damage to heritage sites than sand:cement
- Lower applied cost per m2 than sand:cement
Why Rethink Replastering?
Dryzone Damp-Proofing Cream revolutionised the treatment of rising damp when it was launched in 2000. It was faster to install, less messy, and provided a more reliable barrier to rising damp than conventional damp-proofing systems.
However, it was still used in conjunction with an industry standard sand:cement replastering system that was slow and expensive to install, was unpopular with homeowners and heritage bodies and could often result in a cold wall surface that could be vulnerable to condensation.

What does The Dryzone Express Replastering System comprise of?
Dryzone Damp-Proofing Cream / Dryrod Damp-Proofing Rods
Dryzone Damp‐Proofing Cream and Dryrod Damp‐Proofing Rods offer an effective treatment for rising damp in walls of all types. Both products have been independently tested and proven to form an effective damp‐proof course in existing walls.
- Stop the source of rising damp
- Simple and clean application
- Effective in both new (alkaline) and old (neutral) mortar
A salt and damp resistant adhesive glue for fixing plasterboard directly to masonry surfaces. Provides excellent bonding characteristics to the substrate.
- High moisture resistance
- Strong resistance to effects of salt on masonry
- Forms a strong and long-lasting bond between masonry and plasterboard
A breathable, salt-resistant water-repellent that acts as a primer for Drygrip Adhesive. Applied to walls contaminated with rising damp, the cream greatly weakens the crystal strength of salts forming in or at the masonry surface as damp evaporates. Acts as a primer for Drygrip Adhesive.
- Breathable and long-lasting formulation
- Deeply penetrates to form a durable bond with the masonry structure
- Easy to apply by brush or roller

Apply Dryshield to the wall in a single coat using a large soft brush or roller. Make sure any holes and cracks are filled with cream and that all areas are coated evenly.
Tip: If you leave an opened cartridge in the applicator gun, ensure that the nozzle is covered to prevent the material from drying.
