Floor and Marking Project of Raoping County Library and Archives
Project Background
With the increasing usage of underground parking lots, traditional cement floors face challenges such as rapid wear, dust accumulation, and high maintenance costs. Epoxy flooring, known for its durability, slip resistance, easy cleaning, and aesthetic appeal, has become the preferred solution. This project aims to construct standardized epoxy resin floors covering parking spaces, driveways, and ramps, enhancing overall functionality and user experience.
Technical Specifications
1. Material Structure
(1) Surface Preparation: Concrete grinding (flatness ≤3mm/3m), crack filling with epoxy mortar.
(2) Coating System: Primer (0.1-0.2mm) → Mid-coat (1-2mm with quartz sand) → Topcoat (0.3-0.5mm), total thickness 1.5-3.0mm.
(3) Anti-Slip Design: Ramps incorporate anti-slip aggregates (≥2mm diameter) with alternating colors for visibility.
2. Key Performance
(1) Durability: Withstands frequent vehicle traffic, lifespan 8-10 years.
(2) Slip Resistance: Wet friction coefficient ≥0.5, compliant with GB5768-2009.
(3) Eco-Friendly: VOC emissions ≤50g/L, certified by SGS and EN 14904.
Project Benefits
1. Cost Efficiency: 40% lower maintenance costs vs traditional floors, material cost 50-80 RMB/㎡ (total ~150,000-210,000 RMB for 2000㎡).
2. Rapid Construction: 15-25 days, compatible with old floor renovation.
3. Social Value: Enhances parking lot aesthetics, reduces safety risks, and supports all-weather usage.
Implementation Process
| Phase | Scope | Duration |
Base treatment | Polishing, crack repair, cleaning | 3-5 days |
| Primer and intermediate coating construction | Epoxy primer roller coating+quartz sand intermediate coating scraped flat | 5-8 days |
| Topcoat and Marking | Topcoat coating+hot melt marking | 4-7 days |
| Maintenance acceptance | Curing and curing (≥ 7 days)+performance testing | 7-10 days |
Note: Markings use reflective thermoplastic paint, standard parking space size 5000×2500mm.
Sustainability
1. Eco-Materials: Low-VOC epoxy resins minimize pollution.
2. Long-Term Benefits: High durability reduces renovation frequency and resource consumption.
Project Information
Project Name: Floor and Marking Project of Raoping County Library and Archives
Project timeline: May 2023
Partner: Zhongfude Chuanggong Co., Ltd
Project content and construction area:
1. 1.0mm thick parking space epoxy floor paint: 35000 ㎡
2. 1.5mm thick lane epoxy floor paint: 14000 ㎡
Project material list: epoxy resin primer, epoxy resin intermediate coat, micro quartz sand, epoxy resin surface coat
Acceptance results: Test verification confirms the parking lot epoxy flooring exceeds GB/T 22374-2018 requirements with wear resistance (≤0.03g), compressive strength (≥80MPa), and slip resistance rating (R10). The client has issued written acceptance certification for core specifications including environmental compliance (TVOC<0.5mg/m³), laser-measured flatness (±1.5mm), and adhesion (cross-cut test Grade 1), with particular acknowledgment of its oil resistance and rutting resistance performance.
