In many commercial and hospitality projects, decorative finishes are treated as the final aesthetic layer. However, most failures do not happen because of poor design. They happen because of poor specification.
The problem often starts in one document:
The Bill of Quantities (BOQ).
When decorative concrete systems are vaguely specified, the result is underpricing, material substitutions, execution shortcuts, and ultimately surface failure before or shortly after handover.
If you are an architect, quantity surveyor, developer, or project manager, here is what should be clearly defined in your BOQ when specifying decorative concrete systems.
1. Substrate Preparation Standards
A premium finish cannot compensate for a weak base.
Your BOQ must clearly state:
- Surface condition requirements
- Moisture testing standards
- Crack treatment procedures
- Level tolerance requirements
- Surface priming system
Without these details, contractors may skip essential preparation steps to remain within budget, leading to cracking, debonding, or uneven finishes.
Finishes are only as strong as the substrate beneath them.
2. Specify a Complete System — Not a Product
One of the most common mistakes in decorative concrete projects is specifying a product instead of a system.
A proper decorative concrete system includes:
- Primer type
- Base coat thickness
- Reinforcement mesh (if required)
- Decorative layer composition
- Protective sealer system
Each layer is designed to work together. If even one component is substituted or omitted, performance is compromised.
A bucket is not a specification.
A system is.
3. Define Performance Requirements
Aesthetic appeal should never be the only criterion.
Your BOQ should specify measurable performance standards such as:
- Abrasion resistance
- Water resistance
- Slip resistance (especially in wet areas)
- UV stability (for exterior applications)
- Maintenance requirements
Without performance criteria, there is no benchmark for quality control during execution.
Design must be supported by durability.
4. Application & Quality Control Standards
Even the best system can fail under poor execution.
Include in your BOQ:
- Certified or trained applicator requirement
- Layer curing times
- Environmental condition controls
- On-site supervision standards
- Inspection and approval stages
Clear documentation reduces disputes and ensures consistency from start to finish.
Execution determines longevity.
The Cost of a Vague BOQ
When decorative concrete finishes are loosely specified, projects often face:
- Underpricing and budget overruns
- Substituted materials
- Surface failures
- Contractor disputes
- Client dissatisfaction
Clear specifications protect not just the surface — but the project timeline, budget integrity, and professional reputation of everyone involved.
Why Early Specification Matters
Decorative finishes influence more than appearance. In commercial environments, they affect:
- Long-term maintenance costs
- Renovation cycles
- Brand perception
- Property value
When specification is done correctly at the documentation stage, execution becomes predictable and controlled.
Clarity prevents conflict.
A Strategic Approach to Decorative Finishes
At Incise, we work with project teams to ensure decorative concrete systems are:
- Properly documented
- Technically specified
- Performance-defined
- Installed by trained applicators
Because successful projects are not built by materials alone — they are built on clear documentation and correct execution.
If you are planning a commercial or hospitality project and would like guidance on specifying decorative concrete systems correctly, our technical team is available to support your documentation stage.
