Masonry water-repellent surface treatment — Damp proofing specialist
Describe the masonry surface, its exposure and the moisture problem, and provide any assessment already completed. Ask whether a water-repellent surface treatment is suitable for that substrate. This request does not include injected damp-proof courses or structural waterproofing by default.
Service scope
Assessment and application of a specified water-repellent treatment to a suitable masonry surface after the moisture mechanism and substrate have been identified. Surface impregnation is not automatically a treatment for rising damp, internal condensation, active leakage or permanent water pressure.
What is normally included
- Assess masonry condition and the moisture mechanism
- Prepare the agreed suitable surface
- Apply the specified compatible water-repellent surface treatment
What is not included
- No universal damp cure
- Injection and structural waterproofing require separate scope
- An assumed injection or coating specification
- Applying a treatment solely because a wall is damp
- Injected damp-proof courses and structural waterproofing
- A universal cure for rising damp, condensation or active leakage
Typical tasks
- Assess masonry condition and the moisture mechanism
- Prepare the agreed suitable surface
- Apply the specified compatible water-repellent surface treatment
- Check an agreed sample area where needed before treating the wider surface
- Record application conditions and the treated area for future maintenance
What to include in your brief
- Substrate and exposure
- Moisture diagnosis
- Proposed surface product versus injection treatment
- Wall area, photographs and any existing paint or surface treatment
- Access height and the desired timing of the work
Choosing the right professional
Select a provider who explains substrate suitability, product compatibility and treatment limits. Ask how the diagnosis supports surface treatment rather than assuming every damp wall needs it.
Important considerations
- An unsuitable surface treatment may leave the underlying moisture cause unaddressed
- Substrate condition and previous coatings can limit compatibility
