Untreated concrete 7–12 m²/l Top lacquering 10–20 m2/l Practical coverage depends on the porosity and evenness of the substrate.

Waterborne

The relative humidity of the concrete should not exceed 97%. The temperature of the ambient air, surface or coating should not fall below +10ºC during application or drying. Relative humidity of air should not exceed 90%.

New concrete floor: Remove the laitance layer from the concrete surface by, for example, surface sanding or hydrochloric acid pickling. Remove laitance dust carefully after sanding. Hydrochloric acid pickling is performed with a diluted solution (1 part concentrated hydrochloric acid, 4 parts water). Rinse the floor with plenty of water. The substrate has to be dry, firm and solid before surface treatment. Painted concrete floor: Clean the floor and remove any grease, oil, chemicals and other impurities with Tikkurila Maalipesu cleaning agent. Sand the surface carefully and remove the sanding dust.

First coat:

Prime with Solid Laq thinned 10-20 % with water. The thinner is added to the ready compound and mixed carefully. Finish with Solid Laq thinned 10-20 % with water. Pour the mixture on the floor and apply thinly by roller or spatula. Note! Add the remaining mixture to the next batch of the product, do not scrape it out of the container onto the floor.

The lacquered surface will reach its final wear and chemical resistance approx. 2 weeks after the surface treatment. Avoid cleaning during this time. Clean the surface with a brush, mop or dust cloth. Dirty surfaces can be cleaned with a cleaning tool and a neutral (pH 6–8) washing solution.
