What is Wall Brick Protector used for?

It is a water repellent impregnation developed to reduce the capillary water absorption of brickwork and masonry, helping to prevent damp patches, efflorescence and freeze–thaw damage.

How many coats are recommended?

Typically two coats are applied. Apply the second coat before the first dries (wet-on-wet).

Can it be applied on clinker bricks?

No. For clinker bricks, use a dedicated clinker impregnation product.

What coverage can I expect?

Coverage depends on brick type and porosity. Typical values are 2–3 m²/L for average bricks, and approx. 0.7–1.0 L/m² for very porous reclaimed bricks. Always confirm with a test area.

Water-repellent protection for brick surfaces – impregnation against dampness, efflorescence and frost damage

BRICK IMPREGNATION – Wall Brick Protector

Typical issues it helps with:

Reducing capillary water uptake in brick façades and garden walls
Helping prevent damp patches, surface erosion and spalling
Reducing salt/nitre efflorescence and staining
Lowering the risk of freeze–thaw damage in brickwork and joints

“Silane–siloxane based brick impregnation – water-repellent protection, less dampness, less efflorescence and reduced frost damage.”

What is BRICK IMPREGNATION – Wall Brick Protector used for?

BRICK IMPREGNATION – Wall Brick Protector is an impregnating treatment developed specifically to reduce the capillary water uptake of brick surfaces – for both new and reclaimed bricks.

Brick treated with the product does not absorb water, which helps reduce surface decay, nitre / salt efflorescence, and lowers the risk of frost damage.

If bricks are installed in mortar or another bonding material, treat the surface only after the binder has fully cured and dried. If bricks are laid in sand (walking surface), it is recommended to impregnate them by dipping before installation.

Warning: the product is not suitable for clinker bricks. For clinker brickwork, we recommend AQUA-STOP W CLINKER BRICK IMPREGNATION – CLINKER PROTECTOR.

For chimney bricks, we recommend AQUA-STOP W UNIVERSAL – UNIVERSAL, which was developed specifically for surfaces exposed to high thermal load.

Processing

1) Surface preparation
The brick surface to be treated must be . Remove loose and crumbling parts, deteriorated joints, and any old, peeling coatings. If necessary, clean the surface and allow it to dry completely.

2) Bricks laid in mortar
If the bricks are installed in mortar or another binder, treatment must be carried out , including the joints.

3) Bricks laid in sand (walking surface)
If the bricks are laid in sand (walking surface), the bricks in the product for approx. before installation, then let the excess drain and install.

4) Application on façades and walls
Apply by or so that the material runs on the surface (). Usually are required. Always apply the second coat (wet-on-wet).

5) Application conditions
The surface must not be overheated. Recommended application temperature: . Do not apply to frosty or strongly cooled substrates, or to surfaces overheated by direct sunlight.

6) Test area and re-treatment
Always carry out a to confirm consumption and performance. The special formulation makes it possible to the surface later at any time, if needed.

Warning: On listed or heritage-style buildings, use only after professional assessment and on your own responsibility. A test application is essential.

Coverage

Material consumption depends mainly on brick type, porosity and surface roughness. The guideline values below refer to typical two-coat applications:

Surface type	Recommended coats	Coverage / consumption
New brick surface (average porosity)	2 coats	2–3 m²/L (approx. 0.33–0.50 L/m²)
Very porous reclaimed brick surface	2 coats	approx. 0.7–1.0 L/m²

Typical practical average consumption is approx. 0.7 L/m². Always determine the exact value with a test area.
