Generally four methods are possible to apply the impregnation.
It is highly recommended to impregnate a facade by means of flooding using a coarse droplet spray pattern.
This usually guarantees that a sufficient amount of impregnation is available in order to ensure
penetration into the substrate.
The impregnation can also be applied by airless spraying. In this case it has to be ensured that the impregnating
agent is not atomized.The spraying distance should therefore be 5 - 10 cm.
Application by Lamb's wool rollers or brushes is also possible. A sufficient penetration is provided when
the surface is saturated, i.e. no further impregnating agent is absorbed within a period of one minute. Repeated
impregnation steps ( wet on wet application) may be necessary for very absorbent substrates.
The ideal application temperatures are between +10 °C and +25 °C.
