Painting capability should match the substrate and system, not only colour application. Walls, timber, metal, facades, damp areas, textures, decorative finishes and specialist coatings require different preparation and controls.
How to assess this decision in practice
Ask candidates to explain the sequence for actual conditions rather than only naming a paint brand. A sound answer connects diagnosis, preparation, primer, repair, top coats, weather, tools, inspection and warranty limits.
Test portfolios against relevant substrates and exposure. New interior work does not automatically demonstrate capability with damp facades, exterior timber, corroded metal, floor coatings or decorative finishes.
What to check
Use this list as a starting point. The depth of review should still match the project stage, decision value, documents and risks.
- Request assessment of substrate, moisture, cracks, mould, salts and previous-coating compatibility.
- Check experience with genuinely comparable systems and conditions.
- Compare preparation, primer, filler, top coat, coat count, tools, protection and access scope.
- Create a representative mock-up covering colour, sheen, texture, batch, light and touch-up limits.
- Set intercoat checks, coverage, relevant thickness, cleanliness, defects and warranty.
Turn the review into a recorded decision
- Set the baseline: documents, conditions, dates, parties, reviewed areas and access limitations.
- Separate observed facts, third-party statements, assumptions, risks and professional opinions.
- For each issue, define the required decision, authority, action owner, target and closure evidence.
- Retain document versions and approvals so later changes can be compared against the correct basis.
Questions before deciding
A useful answer should be traceable to documents, site conditions, a responsible party or a clearly stated assumption boundary.
- Which system is recommended for each substrate and exposure?
- Who corrects moisture sources or weak substrates?
- How are the mock-up and final result accepted?
How to document the outcome
Record information sources, review dates, documents read, people interviewed, inaccessible conditions, key findings, decisions, owners and follow-up deadlines. Separate facts, third-party statements, assumptions and recommendations.
For legal, structural, geotechnical, tax, permitting, land, design or specialist-testing decisions, use appropriately authorised and qualified professionals.
