Treat Rising Damp and redecorate in under 24hrs
What is the Dryzone System?
Rising Damp Treatment in 24 hours
The Dryzone System combines the power of our patented Dryzone damp-proofing cream with a modern fast-track replastering system. Rising damp treatment and replastering can now be completed in just 24 hours. Breathable and as effective as a sand:cement render, the Dryzone System allows for ordinary plasterboard to be used to cover up damp and salt contaminated walls.
The three key steps in the Dryzone System:
- Dryzone damp-proofing cream to treat rising damp: solvent-free, patented and the best performing rising damp treatment on the market
- Dryshield Cream to prime the wall: long-lasting protection against damp, salt and mould in just one coat
- Drygrip Adhesive to fix plasterboard: creates a durable bond to masonry that's strongly salt and moisture resistant
The Dryzone System is quicker and cheaper to install per m2 than a sand:cement render, and allows the use of cement-based plasters to be avoided when treating rising damp on heritage projects.
How does the Dryzone System differ from other rising damp treaments?
The Dryzone System 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
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.

How to install the Dryzone System
1. Prepare the wall
In most cases it is necessary to remove the damp/salt contaminated plaster before the Dryzone System can be used.
2. Inject Dryzone damp-proofing cream
Dryzone damp-proofing cream is injected in the usual way. The success of the Dryzone system relies on the high-level of performance provided by Dryzone damp-proofing cream in walls of all types.
3. Apply Dryshield
The Dryshield Cream resists salts that are already present in the wall as a result of historic rising damp. It also acts as a primer for the Drygrip Adhesive – maximising bond strength to the masonry substrate.
4. Fix plasterboard with Drygrip
Drygrip Adhesive has been specifically designed to provide an excellent bond onto masonry surfaces and to be resistant to moisture and salts.
Dryzone System Fixing Plugs are used to hold the plasterboard in position. They are not used to hold the weight of the board – just to allow a smooth join between boards.
5. Finish the job
Apply the final skim coat using a suitable gypsum-based skim plaster. Alternatively dry-joint the boards or simply wallpaper for an even quicker result.
