Most resin floor problems in Qatar and the UAE come down to choosing the wrong contractor — not the wrong product. Here are the 12 questions to ask before you sign.
1. Are you ISO 9001 certified?
If not, walk away. ISO 9001:2015 means a documented quality system, batch tracking, and audit trail — non-negotiable for any project above 1,000 sqm.
2. Can you apply every major resin system?
The right contractor recommends a system based on your floor's load, chemistry and budget — not on a single supplier they happen to push. Ask whether the contractor can supply and apply any major resin brand on the market, and how they decide which one fits your project. A brand-agnostic answer beats a sales pitch every time.
3. Show me three references in the Gulf within the last 12 months
Visit the floors. Look for joint detailing, cove fillets, line-marking quality. Photos lie; site visits don't.
4. What's your substrate prep method?
Right answer: diamond grinding or shot blasting (CSP-3 to CSP-5). Wrong answers: acid wash, "we'll just sand it lightly", or "the concrete looks clean enough".
5. What's the warranty — in writing?
Standard for industrial epoxy: 5 years on workmanship, 10 years on the system. PU mortar: 7 / 15. Get it on letterhead with batch numbers.
6. Can you supply MSDS / TDS for every product?
If they hesitate, they're cutting product. Real applicators issue full data packs at hand-over.
7. What happens if it fails?
Listen for: "We come back within 48 hours, fix at no cost." Anything vaguer means you'll fight for warranty work.
8. Do you carry public liability insurance?
Minimum AED 5M / QAR 5M. Get a copy of the policy.
9. Who is the project supervisor and what's their experience?
Named individual, 5+ years on resin, with the certifications. Not "we'll send a foreman".
10. Can you do night-shift & weekend phasing?
Live operations need this. Confirm in writing — and confirm the price doesn't go up for it.
11. What's the cure time before traffic?
Epoxy: 12–24 hr foot, 5–7 days full load. PU: 24 hr / 5 days. PMMA fast-cure: 4 hr full load. Vague answers = inexperience.
12. Show me the moisture meter, the grinder, the spike shoes.
Real applicators own their equipment. Sub-contracting prep means corner-cutting.
Twelve questions, ninety minutes of your time, potentially ten years of trouble-free flooring. Worth it.
