Alka 312 can be applied with a brush or a roller to the desired thickness.
2 coats of 0.68 L/m2 are required to achieve a dry film thickness (DFT) of 1.2 mm. For UV resistance, coating thickness must abide by the numbers given on this Technical Datasheet. A thinner coating will result in premature degradation. Application temperature of Alka 312 is >5°C to 35°C.
