Dryzone Damp-Proofing Cream is a water-based silicone cream used to create a damp-proof course by bonding with and spreading through sand and cement mortar. When properly applied to a continuous mortar line, it effectively blocks rising damp.
Here's a more detailed breakdown:
- Purpose: To create a damp-proof course (DPC) in walls, preventing rising damp.
- Composition: Typically a water-based silicone emulsion or cream.
- Mechanism: When injected into mortar, the cream spreads and cures, forming a water-repellent barrier. It reacts with the silica present in the mortar, creating a durable, long-lasting seal.
- Application: Usually injected into pre-drilled holes in the mortar line.
- Advantages:
- Relatively easy to apply.
- Less disruptive than traditional DPC replacement methods.
- Effective at preventing rising damp when properly installed.
- Considerations:
- Correct diagnosis of rising damp is crucial.
- Proper application technique is essential for effectiveness.
- Pre-existing wall damage may require additional repair.
In essence, Dryzone cream offers a convenient and effective solution for tackling rising damp issues in buildings by creating a chemical damp-proof barrier within the mortar joints.
