APPLICATION INFORMATION
Consumption Dependent on substrate porosity:
On mortar: ~ 150–200 g/m2
On other porous materials: ~ 300–500 g/m2
(A test is necessary to determine the exact consumption).
Ambient air temperature +5 °C min. / +35 °C max.
Substrate temperature +5 °C min. / +35 °C max.
Waiting time to overcoating Can be overcoated with water and solvent based polymer paints - contact
the paint manufacturer for details.
For overcoating with Sikagard®, SikaColor® Emulsion or solvent based coat-
ing, wait at least 5 hours after the hydrophobic impregnation.

IMPORTANT CONSIDERATIONS safety-related data.
▪ Cement based substrates must be at least seven days
old.
▪ Protect glass surfaces and aluminium frames (possib-
ility of surface damage / staining).
▪ Test on a sample surface before use.
▪ Cannot be overcoated with limewash or cementi-
tious coatings.
▪ On all substrates, the optimum water repellent cap-
ability is achieved after a few days.
▪ Water repellency is significantly reduced if the sub-
strate is cracked.
▪ Refer to the method statement for detailed applica-
tion procedure.
