Our Process
Every balcony project follows our proven multi-step system:
Surface prep: Grind seams smooth, fill with urethane and seam tape
Base coat: applied evenly using water-catalyzed urethane
Color coat: Rolled on to provide adhesive layer for chips
Broadcast chips: for texture and visual appeal
Top coat: a clear, protective urethane seal for long-term durability
The result is a smooth, attractive, and fully waterproof surface that lasts for decades.
