The Tikkurila Hydrosol Masonry Primer is a water-based acrylate impregnation primer designed for masonry and concrete surfaces. It is ideal for users needing to bind, stabilize, and even out the absorbency of porous substrates before applying topcoats on exterior façades. While it significantly improves adhesion and strengthens surfaces, users should be aware that its coverage can vary based on surface texture and porosity.

It is suitable for new or previously painted exterior façades, including roughcast, pebbledash, concrete, cement rendering, building blocks, and boards that are highly absorbent or exhibit chalking and laitance.
The surface must be clean, dry, and free from dust, dirt, and loose particles. Any existing efflorescence or mold should be removed prior to application.
The coverage is approximately 4–8 m² per litre. This rate is affected by the roughness and porosity of the surface, as well as any previous coatings.
Yes, while low-pressure spraying is recommended, it can also be effectively applied by brush or roller.
The primer is dust-dry in approximately 1 hour at 20°C and 50% relative humidity.
You can continue with the finishing paint the next day, assuming the primer is fully dry and conditions are suitable.
Yes, Tikkurila Hydrosol Masonry Primer is suitable for both interior and exterior applications.
Ensure the surface is porous. If the surface is already sealed or non-absorbent, the primer may sit on top. Ensure the product is adequately stirred and applied at the recommended temperature.
This could indicate insufficient primer application or that the surface was heavily degraded. A second thin coat might be necessary, ensuring adequate coverage of all chalking areas. Always remove loose chalk before applying.
Confirm the primer was fully dry before applying the topcoat. Ensure the surface was properly prepared and free of contaminants. The compatibility of the topcoat with the primer should also be checked.
Adjust the sprayer's pressure and nozzle settings. Ensure even, overlapping passes. Consider back-brushing or rolling immediately after spraying to even out the finish, especially on less uniform surfaces.
Setup: Ensure the surface is clean, dry, and free from dust, dirt, and loose particles. Remove any efflorescence or mold before application. Stir the primer thoroughly before use.
Compatibility: Primarily designed for masonry and concrete surfaces including roughcast, pebbledash, cement rendering, building blocks, and boards. It is suitable for both new and previously painted exterior façades. Not intended for use on metal, plastic, or highly glossy surfaces.
Application: For best results, apply using a low-pressure sprayer. Alternatively, use a brush or roller. Apply one coat. Coverage is approximately 4–8 m²/l, depending on the surface's roughness and porosity.
Drying Time: Dust-dry in approximately 1 hour at 20°C and 50% relative humidity. Recoating can be done the following day.
Care: Store in a cool, dry place, away from direct sunlight and frost. Keep the container tightly closed when not in use. Clean application tools immediately after use with water.
