1. Scope and purpose
This manual is intended for the maintenance of industrial coatings used in production environments. It includes checking the epoxy coating, the condition of the expansion joints and the drainage system. This maintenance is performed regularly to ensure the safety, performance and durability of the coatings. Coatings should be checked before starting the production process or after detecting deviations from normal operation.
2. Preliminary safety measures
Important: Before starting any work, perform the procedure of blocking and tagging all energy sources to prevent unforeseen events. Use personal protective equipment (protective gloves, eyes, breathing masks, special shoes).
When using chemical liquids (such as solvents or disinfectants), use additional protective equipment and work in a well-ventilated area. Remove all potentially dangerous tools from the work area and place a fence around the work area.
3. Necessary tools and materials
| Name of the tool | Specification | Quantity |
|---|---|---|
| Microscope with 10x magnification | It is required for inspecting the surface and detecting scratches and cracks | 1 |
| Torque screwdriver with different threads | For fixing or unscrewing knots | 1 |
| A ruler with a resolution of 0.1 mm | To measure the dimensions of expansion joints | 1 |
| Aqualite (foam) for drainage | For filling and restoration of drainage seams | 1 |
| Distance ring | To measure the distance between seams | 1 |
| Dry filter | To clean the surface before applying an epoxy coating | 1 |
| Disinfectant | For cleaning the surface from bacteria, moisture, dust | 1 |
4. Pre-service: Inspection
| Point | Verification | Assessment | Notes |
|---|---|---|---|
| Epoxy coating | The presence of cracks, defects, chips | It is accepted | The coating should be even, without defects |
| Expansion seams | Composition, size, moisture | It is accepted | Seams must be clean, without moisture |
| Drainage system | The presence of outflow, the absence of deposits | It is accepted | Drainage should be clean, without deposits |
| The humidity of the coating | Humidity measurement | It is accepted | Maximum humidity — 15% |
| Security structure | Availability of fences | It is accepted | Definitely |
5. Step by step: Procedure
- Cleaning the surface
Use a dry filter to clean the surface from dust, moisture and other debris. Measure the surface moisture using the moisture change. Humidity should be less than 15%.
Error: Do not use liquid without ventilation.
- Epoxy Inspection
Use a 10x microscope to inspect the surface. Detect chips, cracks, defects. Determine the evenness of the coverage.
Error: Don't use uneven surfaces.
- Measuring Expansion Joints
Use a ruler with a resolution of 0.1 mm to measure the size of expansion joints. They should be within 1-5 mm. Determine the humidity of the seams.
Error: Do not use seams with moisture more than 20%.
- Drainage system
Use Aqualite to fill drainage seams. Check for drainage. Measure the humidity of the drainage system.
Error: Do not use uncleaned drainage seams.
- Security structure
Check for fences. Install a fence if there is none.
Error: Don't use open workspaces.
6. After-service: Inspection
| Test | Expected result | Actual | Pass/Fail |
|---|---|---|---|
| Surface moisture | Less than 15% | ||
| Evenness of coverage | The surface is flat | ||
| Seam size | 1-5 mm | ||
| Drainage outflow | Happening | ||
| Security structure | Available |
7. Technical support: Debugging table
| Symptom | Probable cause | Corrective action |
|---|---|---|
| The surface is uneven | Since, cracks | Remove chips, use Aqualite |
| There is no outflow | Contaminated drainage seams | Clean the seams, use aqualite |
| Surface moisture | Humidity more than 15% | Use a disinfectant |
| The seams are wet | The humidity of the seams is more than 20% | Use a dry filter |
| The presence of deposits | Leakage of liquid | Remove deposits, use Aqualite |
8. Recommended maintenance schedule
| The task | Frequency | Estimate duration | Skill level |
