Alfagel 400 - Protective Gel
Alkali-resistant silicone-based preservative which penetrates well into the substrate. Prevents capillary penetration of rain and splash water into the structure. Allows water vapour coming from inside the structure to pass through. Alfagel 400 prevents salts moving to the surface of the structure. Prevents frost damages.
Thixotropic, gel-type Alfagel 400 can be applied in thick layers (single application) even to vertical surfaces and beneath structures as it will not drip or trickle.
Suitable for protection of concrete and exposed-aggregate concrete.
Facades of residential, office and industrial buildings, warehouses, bridge structures.
Approx. 2.5 - 5 m²/kg.
Normally unthinned. Can be thinned with water if necessary.

Protect from frost. The storing temperature should not exceed +30 °C.
The surface to be treated has to be clean and not wet, the temperature of the air at least
+5 ºC, and the relative humidity of the air below 80 %.
The new surface has to be dry and hardened before application.
Clean the surfaces from dirt, dust and salts. Moldy and mossy surfaces are washed with Tikkurila Mould Removal according to instructions.
Apply Alfagel 400 evenly by spray (airless). Application by brush or roller is also possible. Depending on the porosity of the substrate even 400 g/m² can be sprayed with one treatment but normally 200 g/m² gives sufficient protection.
Vertical surfaces are recommended to be treated from down to upwards.
All possible splashes must be immediately wiped away from window. It is recommendable that windows are covered before treatment.
Cleaning of tools
Clean tools immediately after use with water and detergent.
1 month after treatment dirty surfaces can be gently cleaned with pressure washer without detergent.
Tikkurila Mould Removal (Homeenpoisto) and thorough rinsing can be used to remove alga and mould.
Note! After Mould Removal the surface requires a new treatment with Protective Gel.
