Finngard 500 - Protective Coating for Concrete
Water-borne, alkali-resistant, hydrophobic, acrylate coating protecting the concrete against humidity and carbonation. Maximum grain size approx. 0.5 mm.
For coating concrete
structures, mineral-based building boards, and rendered concrete surfaces.
Residential, business and industrial buildings, warehouses etc.

Protect from frost. The temperature of the product or the container may not exceed +35°C. May not be stored in the sunshine, not even under tarpaulin. Tinted or paint in poorly sealed or partly filled can does not stand long-term storage.
The surface to be treated has to be dry, the temperature of the air at least +5 °C, and the relative humidity of the air below 80 %. Do not paint under strong sunlight.
New untreated surfaces
The substrate has to be sufficiently dried and hardened before treatment. For example painting conditions and thickness of the plaster layer affect the drying and hardening time.
Clean the surfaces from dirt, dust and salts. Wash mouldy, mossy etc. surfaces using Tikkurila Mould Removal according to instructions. Very porous concrete surfaces are recommended to be levelled with Finnseco Polytop Finishing Mortar or Finnseco Levelling Mortar.
Previously painted surfaces
Clean the surfaces from dirt, dust and salts. Wash mouldy, mossy etc. surfaces using Tikkurila Mould Removal according to instructions. Remove flaking or poorly attached paint coats from previously painted surfaces. Choose the method of removal according to solidity of the substrate and type of paint to be removed (e.g. steel-brushing, high-pressure washing with hot water or water-sand blasting). Carry out necessary concrete repair, patching and filling using the Finnseco products as instructed.
The need for priming is defined case by case. Chalking substrate is recommended to be primed with Tikkurila Hydrosol Primer. Water-repelling properties of the substrate can be improved with Tikkurila Silicone Primer. Follow instructions in the data sheet.
Apply two coats. The paint can be thinned up to 5 % with water for priming, if necessary. Finish with unthinned paint.
Stir Finngard 500 well before use. Reserve enough paint from the same batch for one uniform surface, to avoid possible colour differences. Should you need to use two different production batches, paint the joints with a solution of 1 part of old batch and 1 part of new batch. Make sure that this joint is in as inconspicuous point as possible.
The paint should be applied without interruptions.
The recommended coverage values should be followed to ensure the best protection ability.
Applicable national health and safety precautions must be followed in the pre-treatment and coating of substrates containing asbestos.
Protect the surfaces not to be painted.
Mechanical stress can cause lighter visible spots, in particular, in darker painted surfaces. This is a typical feature for all matt facade paints which does not, however, affect the product’s technical performance.
Cleaning of tools
Wash the tools with water. Tikkurila Tool Cleaner is recommended for the removal of hardened paint.
Clean the surface cautiously with pressure washing without detergent at the earliest 1 month after painting. The washing may leave a permanent mark, therefore the area should be delimited imperceptible according to the structure lines. Remove dry loose dirt lightly with a soft brush without scrubbing. Tikkurila Mould Removal can be used to remove algae and mould, rinse off well.
Note: The surface needs always to be recoated after mould wash.
Surfaces painted with Finngard 500 can be re-painted with Finngard 150, Finngard 500 and Finngard Silicone Resin Paint.
