Not sure which category your tile falls into?
Unsealed tiles absorb quickly and require more product. Sealed or glazed surfaces absorb less and need lighter application.

Application + Cure

  • Application: Apply 2 coats for most installations
  • Recoat: Apply second coat once the first has fully absorbed (typically 1–2 hours)
  • Dry Time: Surface should feel dry within a few hours; allow 24 hours before regular use
  • Note: Highly porous surfaces may require additional coats

CHARACTERISTICS

  • Finish: Natural, no added sheen
  • Base: Solvent-based
  • Application: Brush, paint pad, or spray
  • Use: Interior, Exterior, Wet Areas
