If you like it bright and friendly, but do not want to forgo the natural advantages of a clinker façade, the high-quality clinker bricks of our “Grey-white deLuxe” series are just as much the right choice as those of our “Grey deLuxe” series. The white component of this facing brick creates a somewhat looser overall impression, which is particularly noticeable with larger surfaces. These facing bricks are available in both normal format (NF) and thin format (DF) and impress with their cool elegance.

Rainwater penetrates through the masonry and washes out the efflorescent components of the mortar.
Sulphates and carbonates migrate to the outside when the unprotected masonry dries out and crystallize on the surface.
The result is that there are unwanted white spots (efflorescence) on the facing brick.
OLFRY masonry with efflorescence protection
The efflorescence protection, with its molecularly fine, water-repellent layer (approx. 2–4 mm), acts like a protective shield: rainwater can only enter through the joints.
The pores and capillaries of the brick remain open even with efflorescence protection, so the block remains breathable. The moisture in the joints can penetrate unhindered into the brick via the bearing surface – the brick retains its important function as a moisture buffer.
When the masonry dries, the stored moisture migrates as water vapour through the capillary system to the outside again. However, since water vapour does not transport soluble sulphates and carbonates, these do not penetrate to the surface, as is the case with unprotected bricks. And the successful result is naturally beautiful bricks without unsightly efflorescence.
