A solvent-free, elastic two-component polyurethane coating.

• For new and old concrete and asphalt floors exposed to mechanical and chemical stress. • Good resistance to abrasion. • Elongation value approx. 60%. • Withstands water, oils, greases, chemicals and dilute solutions of non-oxidizing acids, alkali and salt solutions. Resists only temporary splashes of oxidizing acids and bleaching chemicals. • Withstands +80ºC dry heat. Does not resist abrupt changes of temperature. • Good impact resistance. • Self-levelling, to be applied with serrated or steel trowel.

• Recommended for industrial and storage facilities, repair shops; e.g. air handling units, process or paper machine units and corridors.

Practical coverage depends on the porosity and evenness of the substrate and on the application method. Film thickness 1 mm coverage approx. 1 m²/litre and film thickness 2 mm coverage approx. 0.5 m²/litre.

Solventfree

The relative humidity of the concrete should not exceed 97%. The temperature of the ambient air, surface or coating should not fall below +15ºC during application or drying. Relative humidity of air should not exceed 70%.

New concrete: Remove laitance by power grinding, vacuum grit blasting or hydrochloric acid etching. Choose the method best suited for the premises. After grinding remove dust carefully with a vacuum cleaner. Hydrochloric acid etching is carried out with diluted hydrochloric acid (1 part concentrated hydrochloric acid, 4 parts water). Rinse with plenty of water. Dry the floor. Old concrete: Remove all grease, oil, chemicals and other impurities by Maalipesu detergent. Remove old peeling paint layer by grinding, milling or vacuum grit blasting. Choose the method best suited for the premises. Clean out pot-holes removing all loose friable material. Open cracks with e.g. an abrasive tool. Remove loose material and dust. If cementitious screed is used, check compatibility with the levelling screed manufacturer.
