Construction Instructions
- The substrate must be dry, firm, flat, dust-free and oil-free; substrate moisture content ＜ 8%.
- Apply in two separate coats. Spread mixed material evenly with a rubber scraper or brush, cross-brush in two perpendicular directions. Apply the second coat after the first layer cures (4–8 hours).
