Ecocal: application

How Ecocal is used:

Ecocal can be applied with a brush or low pressure sprayer. Let Ecocal soak until the foaming is stopped (few minutes). Then rinse with lots of water and clean the applied area thoroughly with a hose or pressure washer.

It can take a few applications before the stains are gone. If necessary reapply Ecocal again and follow the procedure.

Using Ecocal on a stone that contains aluminum and limescale, it’s possible to dilute Ecocal 1:40 with water. The effect of Ecocal is even greater when the diluted water is heated.

Note: sometimes the chemical composition of the limescale does not react with Ecocal and the white stains will not disappear. Ecocal only works on calcareous stone and mortar.

Depending on how much limescale is present in the facade, it could happen that it returns on a later date. Therefore, it is wise to at least protect these parts of the wall/facade by waterproofing it with Oppercon. Oppercon contributes to suppress the white spots from returning and also making your facade/wall water- and dirt repellent.

Note: sometimes the chemical composition of the limescale does not react with Ecocal. Therefor the white stains will not completely disappear. Ecocal has a tendency to work well on calcareous stone and mortar/grout.


Use how much Ecocal:

Depending on tenacity of the stain, 1 litre of EcoCal is sufficient for 8 m2.
