- Adhesive & Sealant Type
- 1K (1 Component) Adhesive
- 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.
