EXPOSED BALCONY CONCRETE FINISHES HAVE EXCESSIVE VARIATION IN COLOUR
Variations in concrete colour are to be expected with cast-concrete construction. Variations are considered acceptable if the finishes provide a general uniformity in appearance when viewed from grade.
One-Year - Work and Materials
Concrete with excessive variation in colour shall be cleaned or coated to provide a uniform finish.
Cast concrete will inherently have colour variations. While upgraded finishes are possible, they are not mandatory and are at the discretion of the design team. There are no requirements in the Ontario Building Code to paint the surface. However, if the builder does apply paint (of the appropriate type) to the surface the warranty shall apply to the installed paint.
