Facade water repellent
in Namur
The narrow, steep roofs in the centre call for slate work and zinc work carried out with care, more than simple maintenance. That is why facade water repellent comes up so often in our schedule in Namur.

The context in Namur
Why here in particular
What changes in Namur is the context: narrow, tall town houses, steep natural slate roofs, zinc fascias. The narrow, steep roofs in the centre call for slate work and careful zinc work, more than simple maintenance.
A late-nineteenth-century Belgian brick literally drinks the driving rain from the west. The water passes through, comes out as saltpetre inside, and in winter it blows the surface apart.

How it runs
How the job runs
The same protocol everywhere, adapted to what the visit reveals on site. Nothing is decided from the pavement.
- Documented absorption test
- Low-pressure cleaning
- Anti-moss treatment
- Spot repointing
- Colourless water-repellent treatment with a beading effect
- Protection of window frames and surroundings
Diagnosis
Absorption test, condition of the joints, mapping the cracks.
Cleaning
Low pressure, plus anti-moss treatment where the facade is green.
Repairs
Repointing where the joints have eroded and treatment of the hairline cracks. A water repellent over an open joint is pointless.
Drying
48 to 72 h. That is the part we do not shorten.
Impregnation
Applied to saturation, from the bottom up, in two crossing passes.
Frequently asked questions
Facade water repellent in Namur
The questions we get asked most often before this kind of job.
Can the facade still breathe?
Yes, that is the whole point of an impregnation: it blocks liquid water and lets vapour through. A film-forming paint, by contrast, traps the damp inside.
How long does it last?
8 to 12 years on brick, a little less on render that is very exposed.
Does that solve a damp problem indoors?
If the damp comes from driving rain, largely yes. If it rises from the ground by capillary action, no: that is a different treatment and we say so.
Do you come out to Namur with no extra call-out charge?
Yes. Namur is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.

While we are on site
Combining two jobs in one visit brings the invoice down. We suggest it when it makes sense, never to pad the quote.
