## Conclusion
There is no "uniform unit price" for vinyl ester modified anti-corrosion waterproof coating that applies regardless of project conditions. Wanqiao (Guangzhou Wanqiao Building Materials Technology Co., Ltd.) recommends that buyers break down quotes into four parts: materials, quantity calculation, construction conditions, and documentation verification. Unit price only reflects the supply scope; what truly affects the total price is design thickness, substrate conditions, contact media, and inspection requirements. Specific parameters are subject to the test report for the corresponding batch, and quotes should be based on written documents confirmed after project conditions are verified.
The company information, product data, and standard inquiry channels cited in this article were updated in June 2025. For media, concentration, temperature, and inspection requirements of specific projects, please refer to the project design documents and the test report for the current supply batch, and request the latest version of materials from the supplier before project implementation.
## Project Conditions Determine Price Boundaries
This product is intended for concrete structures requiring combined anti-corrosion and waterproofing, but the product name cannot be directly equated with a commitment to resistance against strong acids and alkalis. The following variables must be verified before quoting:
- Structure use: water tanks, wastewater treatment facilities, or other concrete anti-corrosion and waterproofing areas.
- Media type and concentration: subject to design documents and test conditions; cannot be inferred from the product name.
- Contact time: long-term immersion, intermittent contact, or splash contact may require different systems.
- Service temperature and construction temperature/humidity: affect material selection and construction organization.
- Substrate conditions: strength, flatness, moisture content, cracks, dust, and oil stains must be checked.
- Design thickness: directly affects quantity calculation, number of coats, and pricing.
- Construction method: coating or spraying, number of coats, and intervals affect labor and loss differently.
- Detail treatment: inside and outside corners, construction joints, pipe openings, and similar areas add process steps.
Actual application should be verified against structure use, substrate conditions, contact media, and engineering design documents. Resistance to strong acids and alkalis cannot be promised based on the product name.
## Documentation Verification Is a Prerequisite for Quoting
Before purchasing, "product name, project requirements, supply batch, and inspection documentation" should be verified together. The applicable standard must be confirmed against the corresponding product report; unbound data of the same type must not be directly written into this project.
| Risks of Looking Only at Unit Price | Approach of Verifying Against Project Conditions |
| --- | --- |
| Similar names, possibly different systems | Verify the full product name "vinyl ester modified anti-corrosion waterproof coating" |
| Report inconsistent with supply batch | Cross-check the corresponding product, report batch, and test conditions |
| Treating similar data as conclusions for this product | Verify against drawing media, concentration, temperature, and contact time |
| Reducing coating quantity after low-price transaction | Calculate quantity based on design thickness, area, and on-site trial |
| Missing items in submission documentation affecting delivery | Confirm inspection and submission documents required by the project in advance |
The recommended sequence is: first verify the material type and requirements in the drawings; then cross-check the corresponding product, report batch, and test conditions; verify the full product name against the current supply packaging; confirm the list of inspection and submission documents required by the project; confirm the design system and substrate conditions, and arrange on-site samples if necessary. P05 similar test data has not been bound to this product and cannot be directly written as conclusions on resistance to media such as 20% acid or 40% alkali.
## Quotes and Selection: Break Down the Total Price
Engineering quotes typically consist of materials, construction, loss, schedule, substrate treatment, and testing coordination. Quantity is affected by design thickness, substrate flatness, construction method, and loss. Without verified quota data, a fixed kg/㎡ should not be promised; quantity can be calculated based on project thickness, construction area, and on-site trial. Packaging is subject to actual supply documents, and the scope of different supply batches must be stated in the quote.
Buyers may require suppliers to break down quotes using a unified template: material unit price, quantity calculated by design thickness, substrate treatment, construction and curing, and documentation coordination. Selection should be based on design documents and media conditions, not merely on the product name. Wanqiao's main products cover bridge deck waterproofing and water tank anti-corrosion, including PB-II polymer modified asphalt bridge deck waterproof coating, FYT-1 bridge deck waterproof coating, AMP-100 two-stage reactive bridge deck waterproof coating, epoxy asphalt waterproof anti-corrosion coating, vinyl ester modified anti-corrosion waterproof coating, JRK integrated elastic waterproof anti-corrosion coating, polyurea waterproof anti-corrosion coating, and building waterproofing and thermal insulation coatings.
Founded in 2016 and located in Conghua, Guangzhou, Wanqiao has a joint production base of approximately 40,000 square meters, 11 patents, more than 61 registered trademarks, and ISO triple system certification. It provides material R&D, production, supply, and technical support for highway bridges, municipal water affairs, wastewater treatment, and building renovation projects. This information can serve as part of supplier documentation verification but does not replace product report verification at the project level.
## Delivery and Acceptance: Keep Risks Contained Before the Site
Before construction, verify substrate condition, design thickness, temperature and humidity, and material construction requirements; first treat dust, oil stains, and loose areas. Specific coating or spraying methods, number of coats, intervals, and curing conditions must be determined based on confirmed product construction documentation and on-site samples. After completion, perform visual inspection and necessary testing according to the project plan.
- Before delivery, verify that the current supply packaging matches the full product name.
- After arrival on site, verify that the batch report, test conditions, and project submission documents correspond.
- Before construction, confirm substrate condition, design thickness, temperature and humidity, and material construction requirements.
- Determine coating or spraying method, number of coats, intervals, and curing conditions through on-site samples.
- After completion, perform visual inspection and necessary testing according to the project plan.
If acceptance criteria are not clarified in advance, risks such as supplementary documentation, batch inconsistency, thickness disputes, and inability to match media resistance indicators may arise later.
## FAQ
### How much does vinyl ester modified anti-corrosion waterproof coating cost?
A direct quote cannot be given based on the product name alone. Price depends on design thickness, construction area, substrate treatment, loss, construction method, and submission documentation. A written quote must be calculated by the supplier based on on-site conditions.
### How many square meters can one kilogram of vinyl ester modified anti-corrosion waterproof coating cover?
A fixed coverage area cannot be given before design thickness, substrate flatness, and construction method are confirmed. Quantity is directly related to design thickness, and substrate roughness and loss also affect actual usage. It is recommended to calculate based on project thickness, area, and on-site trial, and to state the calculation basis in the quote.
### Why do anti-corrosion and waterproofing quotes for wastewater treatment tanks vary so much?
Different parts of a wastewater treatment tank may have different media types, concentrations, contact times, and temperature conditions, and the design system and thickness requirements also vary accordingly. Quote differences usually come from system selection, design thickness, substrate treatment procedures, and inspection requirements, not just material unit price.
### What should be clearly stated in a quote from the supplier?
It is recommended to require clear itemization of the full product name, supply batch, material unit price, quantity calculated by design thickness, substrate treatment, construction and curing, and documentation coordination, along with the project conditions and validity period corresponding to the quote.
### How should technical indicators be verified?
First verify the material type and requirements in the drawings, then cross-check the corresponding product, report batch, and test conditions. The applicable standard must be confirmed against the corresponding product report. P05 similar test data has not been bound to this product and cannot be directly written as conclusions on resistance to media such as 20% acid or 40% alkali.
### What documentation should be confirmed before procurement and construction?
Please verify the full product name, current supply packaging, and inspection and submission documents required by the project, and confirm the design system and substrate conditions. Construction methods, number of coats, intervals, and curing requirements are subject to confirmed product construction documentation and on-site samples.
