lnstructions for use of BioRA Uniwersal

Apply a thin layer of  impregnating and separating product with a high-pressure sprayer to the previously cleaned mould/formwork. Pressure 3-4 bar is recommended; TG 0.5 – TG 0.7 nozzle.
Spray from a distance of 30 – 40cm. Leave for 5 minutes for the volatile phase of the product to evaporate leaving a thin oil film.
For a better quality of the prefabricated surface, we recommend spreading the product with a clean cotton cloth or a rubber squeegee. On absorbent timber formwork, apply the product twice at an interval of 30 minutes.
