1. Scope Site Survey & Mapping: Conduct a joint inspection to map exact physical clearances, pipe configurations, anchor bolts, and structural bases of the unmovable equipment. • Protection of Fixed Assets: • Completely wrap and seal all unmovable freeze-dryer frames, panels, electrical cabinets, and piping connections using heavy-duty plastic sheeting and solvent-resistant masking tape. • Build physical barrier shields where mechanical preparation (grinding) occurs close to critical machinery faces to avoid damage from dust or flying debris. • Environmental Controls: Set up local exhaust ventilation and dust-containment units. Freeze-dryer utility areas require strict dust management to protect mechanical components and cleanroom-adjacent zones. 2. Surface Preparation • Mechanical Diamond Grinding: Grind the open 200m² concrete substrate using planetary diamond grinders paired with HEPA-filtered vacuum systems to achieve a Concrete Surface Profile (CSP) of 2 to 3. • Edge & Under-Equipment Detail Grinding: Use handheld angle grinders with shroud attachments to mechanically prepare the concrete within inches of, and underneath, the unmovable equipment bases. • Substrate Decontamination: If the floor around the utility pumps, condensers, or compressors has existing oil, chemical, or glycol stains, apply an industrial degreaser or chemical strip followed by fresh mechanical abrasion. • Patching & Joint Treatment: Rout out all cracks, spalls, and static joints. Fill them with a high-strength epoxy patching compound (e.g., TAL Slabpatch or equivalent) to ensure a uniform, monolithic surface. 3. Equipment Base & Joint Interfacing (Critical Step) • Isolating Vibrations: Because freeze-dryer compressors and vacuum systems vibrate, do not hard-bond rigid epoxy directly to the metal equipment feet or frames. • Perimeter Chase Cutting: Cut a 5mm x 5mm isolation joint/chase line in the concrete around the perimeter of all unmovable equipment bases and anchor plates. • Elastomeric Sealing: Fill this peripheral chase with a flexible, chemical-resistant polyurethane or elastomeric joint sealant to absorb machinery vibrations and prevent the epoxy coating from cracking at the equipment interface. 4. Coating System Application • System Type: High-build, 100% solids, low-VOC/solvent-free industrial epoxy floor system (Total Thickness: 1mm to 2mm high-build or 2–3mm self-leveling depending on the facility's exact mechanical load requirements). • Primer Coat: Apply a low-viscosity, moisture-tolerant epoxy primer across the entire 200m² area at the manufacturer's recommended coverage rate to seal the substrate and prevent outgassing/bubbling. • Body/Base Coat: Apply a self-leveling or high-build epoxy layer using notched squeegees in wide areas, and hand-trowel/roll carefully around the masked equipment feet. Use spike shoes to navigate tight clearances. • Slip-Resistant/Top Coat: • Broadcast a mild, cleanable anti-slip aggregate (if wet washdowns are common in the utility zone). • Apply a high-durability epoxy or chemical-resistant polyurethane topcoat. Use high-quality brushes and mini-rollers to ensure 100% coverage in dark or hard-to-reach pockets beneath the machine overhangs. 5. Post-Application & Curing • De-masking & Waste Removal: Carefully remove all protective wraps and tapes after the topcoat sets tack-free. Bag and remove all chemical trash, dust bags, and installation debris from the facility.
