Installation Guidelines & Best Practices
Proper Modular Cleanroom Flooring Installation
1. Substrate Preparation
Concrete moisture content must be ≤4% (ASTM F1869), surface profile 25-50μm (CSP 3-4), and flatness tolerance ≤3mm/3m. Deiiang™ specifications require diamond grinding for optimal adhesion.
2. Moisture Barrier & Priming
Apply epoxy moisture barrier systems at 200-300g/m² for substrates with RH 4-6%. Primer coat coverage: 150-200g/m² with minimum cure time 8-12 hours at 20°C.
3. Material Application
Epoxy: Apply in 2-3 coats with aggregate broadcast for thickness build. Vinyl: Sheet flooring requires seam welding with 2-3mm weld rods. Raised Floor: Install pedestals at 600x600mm or 1200x1200mm grid.
4. ESD Grounding System
Install copper grounding grid at 3x3m pattern with 2.5mm² tinned copper wire. Measure surface resistance: 10^6-10^9 Ω for static dissipative, 10^4-10^6 Ω for conductive floors.
Proper installation of Modular Cleanroom Flooring requires strict adherence to environmental conditions, with Deiiang™ quality control data showing that installations maintaining temperature 18-25°C and humidity 40-60% RH during application demonstrate 35% fewer defects and 50% longer service life.

Maintenance, Cleaning & Lifecycle Management
Daily Cleaning Protocol
Use neutral pH cleaners (pH 6-8) with deionized water. Microfiber mops with 0.3μm particle capture. Avoid waxes, oils, or silicone-based products that degrade ESD performance.
Weekly/Monthly Testing
Surface resistance mapping (9-point test), visual inspection for damage, slip resistance verification (≥0.5 DCOF). Deiiang™ maintenance contracts include quarterly certification testing.
Lifecycle Management
Epoxy refinishing every 5-7 years, vinyl replacement 7-10 years, raised floor panel rotation 3-5 years. Budget 15-25% of initial cost for mid-life refurbishment.

Frequently Asked Questions
What is the best cleanroom flooring for ISO Class 5 applications?
For ISO Class 5 environments, seamless epoxy or polyurethane flooring typically provides the best performance due to minimal particle generation, excellent cleanability, and consistent ESD protection. Deiiang™ project data shows epoxy achieves 99.2% reduction in particle shedding compared to other materials in ISO Class 5 applications.
How often should cleanroom flooring be tested for ESD performance?
ESD performance should be verified quarterly through 9-point resistance testing, with more frequent testing (monthly) in high-traffic areas or environments with aggressive chemical exposure. Deiiang™ maintenance programs include automated testing reminders and documentation to ensure continuous compliance.
Can existing flooring be upgraded to meet cleanroom requirements?
Existing flooring can often be upgraded through surface preparation, application of epoxy or polyurethane coatings, and installation of proper ESD grounding systems. However, the substrate condition and moisture content must be evaluated first. Deiiang™ assessments successfully upgrade 70% of existing floors to meet cleanroom standards at 40-60% of replacement cost.
