Setting Instruction:
If used against moisture:
The substrata must be clean and enough absorbent to help the product penetration. Usually two coats of primer are applied, with an interval of 3 to 8 hours between one-another. When laying the first coat, the product must be thinned with DILUENTE PU in a ratio of 30%. When laying the second coat use it neat.
If used to consolidate:
Apply only one coat, thinned with DILUENTE PU in a ratio of 50-100% depending on the substrata absorbency. It is most important to avoid it forming a film.
If used as binder:
Mix one part of PRIMER PU with 5-6 parts of dry sand.
Surface preparation:
