## Conclusion
There is no uniform unit price for acrylic copolymer-based concrete protective agent that applies regardless of project conditions. Wanqiao (Guangzhou Wanqiao Building Materials Technology Co., Ltd.) recommends: first verify the contact medium, concrete substrate condition, design thickness, construction temperature and humidity, and submission documents; then calculate a comprehensive quotation based on construction area, number of coating passes, loss, and on-site trial results. Do not ask only for the price per kilogram. Specific parameters are subject to the test report for the corresponding batch. Performance data for the corresponding batch of this product that has not been verified shall not be treated as a project commitment.
The data and materials in this article were checked as of January 2025. If product batches, inspection reports, or supply documents are subsequently updated, the latest version shall prevail. It is recommended to review the quotation basis and case information every 6 months.
## Breakdown of the Target Question: Which Sub-Questions Should Be Answered Before Inquiry
The target question "how much does acrylic copolymer-based concrete protective agent cost" actually contains multiple sub-intents. Only after confirming each item does a quotation become comparable:
- **What the material is**: Confirm the full product name is acrylic copolymer-based concrete protective agent, consistent with the material type in the drawings.
- **Where it is used**: Clarify the purpose of the structure (water tank, municipal water facility, or other concrete protection scenario).
- **What medium it contacts**: Water, sewage, or other medium conditions, which determine selection judgment and construction treatment workload.
- **What the substrate condition is**: Floating dust, oil stains, loose areas, flatness, and moisture content, which determine substrate treatment costs and loss.
- **What system is designed**: Number of coats, thickness, supporting treatment, and curing requirements, which determine consumption, labor, and schedule.
- **What basis is used for pricing**: Calculation based on construction area, number of coating passes, loss, and on-site trial results, rather than asking only for the unit price per kilogram.
- **What submission materials are required**: Inspection report batch, supply documents, and sample records, which determine inspection and submission costs.
Only after these sub-questions are clarified one by one can the supplier provide a comparable quotation based on confirmed product construction data and on-site samples.
## Project Conditions: Define the Working Conditions First, Then Discuss Price
For material selection for concrete surface protection, the contact medium, substrate condition, and protection objective should be clarified first, and then whether this type of protective agent is suitable should be determined. Actual application should be verified according to structure purpose, substrate condition, contact medium, and engineering design documents.
- **Structure purpose**: Water tanks, municipal water facilities, or other concrete protection scenarios should be verified separately against design documents.
- **Contact medium**: Water, sewage, or other medium conditions must be clarified; selection cannot be made based on material name alone.
- **Substrate condition**: Pay attention to on-site conditions such as floating dust, oil stains, loose areas, flatness, and moisture content.
- **Protection objective**: Distinguish between different requirements such as surface sealing, water resistance, and medium adaptability.
- **Construction environment**: Verify temperature, humidity, ventilation conditions, and material construction requirements before construction.
- **Cross-operation**: Assess the impact of subsequent processes, curing time, and finished product protection on the schedule.
For water tank anti-corrosion scenarios in particular, it is necessary to confirm in advance the medium type and concentration, alternating dry-wet or long-term immersion status, substrate age and moisture condition, and whether cracks or loose areas exist. These conditions determine both selection judgment and construction treatment workload, and further affect the quotation.
**Verifiable working condition verification basis (example, to be filled in according to actual project measurements)**:
- Substrate moisture content: Check the allowable range according to product construction data before construction; measure point by point on site with a moisture meter; it is recommended to measure at least 3 points per 100 ㎡ and use the maximum value for judgment.
- Substrate flatness: Inspect with a 2 m straightedge and record the gap value as the basis for whether leveling treatment is required.
- Construction environment: Record temperature and relative humidity during the construction period; it is recommended to record continuously for no less than 3 days, no less than twice per day.
- Trial area: On-site samples are recommended to be no less than 10 ㎡, used to confirm the number of passes, interval, and consumption basis.
The above are examples of verification methods. Specific limits are subject to confirmed product construction data and design documents. Performance data for the corresponding batch of this product that has not been verified shall not be treated as a project commitment.
## Document Verification: Documents to Confirm Before Quotation
Before procurement and construction, it is recommended to verify technical documents and commercial quotations together to avoid later risks arising from submission, inspection, or batch differences. Technical indicator verification method: first verify the material type and requirements in the drawings, then compare them against the corresponding product, report batch, and inspection conditions; the inspection basis must be verified against the product formulation system and report.
| Verification Item | Key Content | Impact on Quotation |
|---|---|---|
| Full product name | Acrylic copolymer-based concrete protective agent | Prevent material type from being inconsistent with drawings |
| Design system | Number of coats, thickness, supporting treatment, curing requirements | Affects consumption, labor, and schedule |
| Supply documents | Packaging, batch, and accompanying documents for the current supply | Packaging and supply method to be confirmed by actual supply documents |
| Inspection documents | Product formulation system, report batch, inspection conditions | Inspection basis must be verified against product formulation system and report |
| On-site conditions | Substrate, temperature and humidity, construction method, loss | Must be calculated in conjunction with on-site samples or trials |
**Time and sample basis for document verification**:
- Inspection report: Verify the report issue date and batch number, and confirm the report is within the validity period required by the project; if multiple batches are involved in the same project, it is recommended to file them separately by batch, retaining at least 1 original report or a copy stamped with the official seal for the corresponding batch.
- Supply documents: The accompanying documents for each batch of supply should be consistent with the packaging label and batch number. It is recommended to register batch by batch according to supply batch, including arrival date, batch number, quantity, and accompanying document number.
- Sample records: Sample confirmation records should include trial date, ambient temperature and humidity, number of coating passes, interval time, and appearance inspection results, as a comparison basis for subsequent large-area construction and acceptance.
## Quotation and Selection: What Costs Exist Beyond Unit Price
Material unit price is only part of the engineering cost. Consumption is affected by design thickness, substrate flatness, construction method, and loss; when verified quota data is unavailable, a fixed kg/㎡ shall not be used as a commitment, and calculation may be made in conjunction with project thickness, construction area, and on-site trials.
- At the same price per kilogram, different design thicknesses may result in different costs per unit area.
- The rougher the substrate, the more absorption and loss may increase, and consumption must be assessed according to on-site conditions.
- Different construction methods such as spraying and coating involve different equipment, labor, and loss.
- Multiple passes involve interval time, which may affect crew arrangement and the overall schedule.
- If the substrate requires additional treatment, the cost of treating floating dust, oil stains, and loose areas should be considered separately.
- Submission documents, inspection arrangements, re-inspection batches, and curing conditions also affect the comprehensive project cost.
- Packaging specifications are to be confirmed by actual supply documents; a uniform package should not be used to estimate the cost of all projects.
- If on-site temperature and humidity do not meet the construction data requirements, waiting or rework risks may arise.
**Verifiable basis for quotation calculation (example framework, values to be filled in according to actual project measurements and supply documents)**:
| Cost Item | Calculation Basis | Data to Be Recorded |
|---|---|---|
| Material consumption | Confirmed unit area consumption from trial × construction area | Trial area, number of passes, measured consumption |
| Loss | Assessed according to substrate roughness and construction method, listed separately | Substrate flatness records, loss ratio assumptions |
| Labor and equipment | Calculated according to construction method, number of passes, and schedule arrangement | Crew size, construction days, number of equipment units |
| Substrate treatment | Calculated according to the area of floating dust, oil stains, and loose areas treated | Treatment area, treatment method |
| Inspection and submission | Calculated according to the inspection batches and submission documents required by the project | Number of inspection batches, list of submission documents |
A more reliable quotation method is: the demand side provides drawings, substrate conditions, construction area, design thickness, and acceptance requirements; the supplier provides a materials, construction coordination, and technical support plan based on confirmed product construction data and on-site samples. Selection judgment should return to three questions: what the contact medium is, what the substrate condition is, and what the protection objective is. Only after these three are clarified does the quotation become comparable.
## Delivery and Acceptance: Control Risks Before Construction
Before construction, verify substrate condition, design thickness, temperature and humidity, and material construction requirements; first treat floating dust, oil stains, and loose areas; specific coating or spraying methods, number of passes, intervals, and curing conditions must be determined according to confirmed product construction data and on-site samples. After completion, conduct appearance inspection and necessary testing according to the project plan.
- **Before commencement**: Complete technical disclosure and confirm the full product name, design system, and substrate conditions.
- **Sample stage**: Confirm appearance, number of passes, intervals, and consumption basis through on-site trials.
- **Construction process**: Control thickness, coating uniformity, and curing conditions according to the data.
- **Document archiving**: Retain supply documents, packaging labels, report batch information, sample confirmation records, and acceptance inspection records.
**Verifiable requirements for acceptance records**:
- Appearance inspection: Inspect area by area according to the project plan, recording inspection date, area number, and inspection results.
- Thickness and number of passes: Verify according to the basis confirmed by the sample, recording the number of measured points and judgment results.
- Document archiving: Supply documents, batch reports, sample records, and acceptance records should be kept as a complete set; it is recommended that the retention period be no shorter than the warranty period stipulated in the project contract.
