A good epoxy flooring contract answers 6 questions before signing: what work, with which materials, how thick, accepted against which criteria, paid when, and who repairs defects. This article is a checklist of 10 clause groups to review before signing — not a contract template, and not a substitute for legal review of a specific contract.
This article is for general reference. The framework for construction contract content in Viet Nam is set out in Decree 37/2015/ND-CP — under which advance payment, payment, suspension, termination and warranty are all matters the parties agree in the contract. This article cites no specific article numbers and does not claim to be a Kadier standard contract template.
The contract’s role: locking scope, locking acceptance criteria
Epoxy application disputes usually do not start with coating quality, but with what was not written down: thickness not stated cannot be measured, an unstated area measurement method cannot settle quantities, unstated acceptance criteria leave both sides believing they are right. A good contract locks all three before work begins.
Checklist: 10 clause groups
1. Scope and measured quantities
State clearly the work zones, the boundary of each zone, how area is measured (whether corners, wall bases and auxiliary areas are included or excluded), and how to handle re-measurement differing from the quotation area.
2. Materials, coating system and attached TDS
State the coating system name — for example RollCoat, LevelFlow, StatGuard, AquaBase — the product code, number of coats, designed thickness, and attach the TDS of the exact code as the technical basis.
3. Substrate preparation and substrate conditions
State the substrate preparation items already included, the assumption about the substrate condition at signing, and the mechanism for handling a real substrate that differs from the assumption. Compare how substrate condition affects quotations and what substrate preparation costs include.
4. Schedule and site conditions
Work duration, the investor’s site handover milestones, out-of-hours or shift-work conditions, and responsibility if site handover is late.
5. Acceptance and measurement criteria
Acceptance against which criteria: thickness, adhesion, appearance, and for anti-static systems how electrical resistance is measured. Acceptance in parts or only overall acceptance, and whose signatures the acceptance record requires.
6. Payment and variations
Payment milestones tied to accepted work milestones, documents accompanying each instalment, and the mechanism for agreeing variation prices before work. Specific amounts follow the contract for each project.
7. Warranty and maintenance
See details at warranty and maintenance in an epoxy flooring contract. In the contract, this clause must state the items, conditions, defect-reporting process and the user’s maintenance obligations.
8. Suspension and termination
In which cases work may be suspended, who has the right to suspend, how costs and schedule are adjusted on suspension, and the termination conditions and settlement method on termination.
9. Safety and insurance
Responsibility for site occupational safety, protective equipment, fire prevention, and insurance for people and property during work — which party bears each.
10. Dispute resolution
The sequence of negotiation, then mediation, then the competent authority; avoid a clause that only says “resolved in accordance with the law” with no specific sequence.
The five most common gaps
- No thickness and number of coats stated — no basis for acceptance measurement.
- No area measurement method stated — payment quantities cannot be settled.
- No substrate preparation stated — variations for a poor substrate become disputes.
- No acceptance criteria stated — “beautiful” or “acceptable” is entirely subjective.
- Open variations — work first, price agreed later, is a recipe for dispute.
Before signing: cross-check 3 documents
Place the quotation, the contract and the TDS side by side and check: do the coating system and thickness in the contract match the quotation and the TDS? Does the substrate preparation in the contract match the quotation scope? Can the acceptance criteria in the contract be measured with the equipment and methods stated? Wherever there is a mismatch, correct it before signing — correcting after signing is always more expensive.
Frequently asked questions
Can an online contract template be used to sign an epoxy job?
Its framework can be referenced, but all 10 clause groups above must be completed for the specific project, especially the coating system, thickness, substrate preparation and acceptance criteria. A general template without these parameters is not enough to sign.
Is a verbal agreement, or just a quotation, enough?
Not enough for a project with the value and technical risk of an epoxy floor. A quotation is a price offer; only a contract locks scope, acceptance criteria and responsibility when problems occur.
Does a specific contract need a lawyer’s review?
For large projects, many zones or special technical requirements, the legal department or a lawyer should review it before signing. This article is only a reference checklist, not legal advice for a specific contract.
