1. Introduction to Dryzone DPC
Dryzone Damp Proofing Cream is a high-strength, patented injection cream designed for the treatment of rising damp in masonry walls. Its unique formulation ensures effective spread throughout the mortar, creating a new damp-proof course. This manual provides detailed instructions for the proper application and use of Dryzone DPC to ensure optimal results.

3. Safety Information
Always read the product label and Safety Data Sheet (SDS) before use. Adhere to the following safety precautions:
- Personal Protective Equipment (PPE): Wear appropriate gloves (e.g., nitrile or rubber) and eye protection (safety glasses or goggles) to prevent skin and eye contact.
- Ventilation: Ensure adequate ventilation in the work area.
- Storage: Store in a cool, dry place, away from direct sunlight and extreme temperatures. Keep out of reach of children and pets.
- First Aid: In case of contact, rinse immediately with plenty of water. If irritation persists, seek medical attention.
- Disposal: Dispose of empty containers and any unused product according to local regulations.
4. Preparation
Proper preparation is crucial for effective damp-proofing. Ensure the wall is prepared as follows:
- Remove Obstructions: Clear any skirting boards, plaster, or other obstructions from the wall area to be treated.
- Clean Surface: Ensure the wall surface is clean and free from loose debris, dust, or efflorescence.
- Tools Required: You will need a drill with an appropriate masonry bit (typically 12mm), a cleaning brush or air pump to clear holes, a standard caulk gun, and a measuring tape.
5. Application Instructions
Follow these steps for the correct application of Dryzone Damp Proofing Cream:
Figure 3: Overview of the four-step application process.
- Drill Holes:
Drill a series of 12mm diameter holes horizontally into the mortar course at the lowest practical level, typically 150mm above ground level. For solid walls, drill holes to within 20-30mm of the opposite face. For cavity walls, drill through the first leaf, across the cavity, and into the second leaf to within 20-30mm of its outer face. Space holes approximately 120mm apart.
- Clear Holes:
Thoroughly clear all drilled holes of dust and debris using a brush or compressed air. This ensures maximum penetration and effectiveness of the cream.
- Insert Cream:
Cut the end off the Dryzone DPC tube and attach the supplied application nozzle. Insert the tube into a standard caulk gun. Fully insert the nozzle into the drilled hole and inject the cream continuously until the hole is completely filled. Slowly withdraw the nozzle as you inject to ensure even filling.

- Finish the Job:
Once all holes are filled, they can be sealed with mortar or a suitable filler. Allow the cream to diffuse and cure over time. Re-plastering can typically commence after the wall has had sufficient time to dry out, which can vary depending on the initial moisture content and environmental conditions.
6. Coverage Information
The coverage of Dryzone DPC depends on the wall thickness. For a standard 9-inch (225mm) solid brick wall, each 310ml tube of Dryzone will cover up to 1.7 linear meters. Adjust the quantity of tubes based on your wall dimensions and the total linear meters requiring treatment.
7. Maintenance
After application, monitor the treated area for signs of drying. Ensure good ventilation in the treated rooms to aid the drying process. Once the wall has dried, maintain good building practices to prevent future moisture ingress from other sources (e.g., leaking pipes, faulty gutters, condensation).
8. Troubleshooting
- Application Difficulty: If you find the cream difficult to inject, ensure the nozzle is fully inserted and that the caulk gun is functioning correctly. The cream's consistency is designed for optimal spread, but very cold temperatures can make it stiffer. Storing tubes at room temperature before use can help.
- Dampness Persists: If dampness persists after several weeks or months, re-evaluate the source of the damp. Rising damp treatment only addresses moisture rising from the ground. Other issues like penetrating damp, condensation, or leaks will require separate solutions. Ensure all holes were properly filled and spaced.
