FAQ
You will find answers to many of your questions here:
How much Badgeon is needed?
Usage is determined by the substrate, the moisture level of the substrate, the dilution of the Badgeon and the painting technique.
As a specification, we advise: 3 kg/m², unless deeper grouts need to be filled.
Once you have started work (after about 10 m²), check the usage and possibly add some extra moisture to the substrate, or dilute the Badgeon a bit more.
How to choose a Badgeon colour?
The colour of the Badgeon is determined by the degree of absorption of the substrate. Highly absorbent substrates will yield a darker colour. This causes the typical colour nuances in the Badgeon. This makes the colour chart indicative.
It is advisable to paint a sample on the (moistened) substrate that is going to be painted and to point out to your client that colour nuances are a characteristic of mineral Badgeon.
How can Badgeon be polished?
After it has set (15-30 min.), Badgeon is polished using a moistened sponge.
Uniform polishing (rubbing up) creates a softer, less grainy look and stroke marks will become less visible.
Local polishing will cause a dark mark, which will also be permanently visible permanently after drying.
What are the creative possibilities with Badgeon?
Besides creating patches and colour nuances through polishing, you can also experiment with pigments.
Once the Badgeon has set (15-30 min.), a suitable pigment, dissolved in water can be rubbed in locally with a sponge. This is how stones with a different tone can be applied.

Can Badgeon be removed?
Badgeon cannot be removed, but can be painted over with classic façade paints once it has hardened completely.
How long will a Badgeoned façade continue to look good?
This very much depends on the circumstances. A dusty environment, a run-off of rainwater, or dense plant growth will soil the badgeoned surfaces more quickly.
Badgeon is a breathing, moisture-regulating and absorbent paint, comparable to a mineral paint
After some time (5-10 years) Badgeon needs to be freshened up with a new layer of Badgeon.
Badgeon will stay beautiful longer if a waterproof product is applied, however, the characteristic Badgeon look will then disappear. Repainting the surface is really only possible when the product has all but disappeared.
Which substrates are suitable for Badgeon?
The substrate must be homogenous, mineral and absorbent, dust- and grease free.
Non homogenous substrates could show colour nuances because of the various absorption levels.
Moistening could improve the homogenous absorption of non homogenous façades.
Façades that are not sufficiently absorbent (certain wire-cut-bricks with low porosity <5%), will not absorb the Badgeon as well, which has a negative effect on adhesion. Bricks with low porosity do no need to be moistened, or less so, beforehand.
What preparation is needed for the substrate?
Clean the substrate with a high-pressure cleaner. Remove all moss.
Moisten before applying Badgeon (check for sufficient absorbency).
Do not apply any primer or impregnation as this will reduce absorption.
Façades that have been treated with water resistant products in the past are not suitable for Badgeon.
How to prevent block-formation when applying Badgeon.
Prevent block-formation by:
- Painting in irregular forms
- Well-moistened façades facilitate the spreading of the paint
- A diluted 2nd layer spreads better (faster painting = less block-formation)
- Polishing afterwards may partly remove block-formation
What about bad grouting?
Badgeon can be applied to very old, damaged façades. Loose grouting needs to be removed. Cracks in the grouting are not a problem.
If deep grouts need to be filled, it is most important to allow the Badgeon to dry fully after application of the first layer. Once it has dried there will be some contraction cracks which will be filled perfectly with the second layer.
Drying time of Badgeon?
The drying time is determined by several factors (climatic circumstances, thickness of the layer, substrate) and ranges between ½ an hour to 6 hours. In misty or rainy weather conditions it could take several days.
When the colour of the Badgeon becomes lighter, it is dry.
The drying time may be influenced by the moisture level of the substrate.
Is there a white film on the Badgeon?
Badgeon needs to be protected from moisture until it has completely dried.
Long-term, stationary moisture may cause a white film (bleeding). The white film will be dissolved by rain and disappear.
New brickwork always carries the risk of bleeding. Bleeding is caused by salts from the stone or the mortar, which can be brought to the surface by moisture. These salts combine with the moisture in the Badgeon (which breathes and is absorbent) and form a white film once the water has evaporated
How can one use the Badgeon once it has been prepared?
Badgeon is hydraulic; once mixed with water the Badgeon can be used for 3-5 hours.
How is the Badgeon powder prepared?
Take the 25 kilo bag of Badgeon powder
Fill a tub with at least 10 litres of water
Add one jar of pigment (400 grams) and mix mechanically.
Add the Badgeon powder to the water and leave for 5 minutes (the powder absorbs water, do not add anything else) and then mix to a homogenous mass
If necessary add some more water for the desired consistency, depending on the substrate and the technique.
