Installation Guidelines

The surface to be coated must be clean, dry and free of oil, grease, dirt and foreign residue. To obtain optimum adhesion of surface and coating we recommend using a primer (e.g. PC 11-010).
Use PC 31-020 as supplied and mix it with dry rubber granules as follows:
▪ 20 parts per weight PC 31-020
▪ 100 parts per weight rubber granules
This mixture can be applied with specially designed pavers in order to obtain uniform, flat surfaces.
Cure Time
The cure time varies with temperature and humidity. High temperature and high humidity will decrease cure time while low temperature and low humidity will increase it.

Storage

Store PC 31-020 in a dry and cool place. Shelf life of product stored in unopened original containers is 6 months. Protect contents against moisture and frost. After prolonged storage, examine the suitability of PC 31-020. Close opened containers carefully, protect contents against moisture and use as soon as possible.
