Process NameDetailed Practices and RequirementsSingle-pass Usage (kg/m²)
Base Treatment1. Base strength: Not less than C20./
2. Base flatness: ≤ 5mm when measured with a 2m straightedge.
3. Base dryness: Surface moisture content of the substrate < 8%.
4. Repair hollowing and cracks on the ground in advance.
5. Fully grind the concrete substrate.
Epoxy Layer (Primer)1. Use WEDO-0301: Mix the base paint and curing agent in the specified ratio and stir evenly.0.15 (Scrape coating) / 0.3 (Roller coating)
2. Apply evenly with a roller.
3. Use a brush for application at door edges, corners and machine corners.
Epoxy Layer (Mortar)1. Use WEDO-0302: Mix the base paint and curing agent in the specified ratio and stir evenly; add quartz sand (generally 80–120 mesh) at the recommended ratio of paint: quartz sand = 1: 0.2–1, and stir evenly.0.3–0.5
2. Trowel integrally with a trowel; the number of construction passes can be adjusted according to the actual situation.
3. Grind and remove dust after curing.
Putty Layer1. Use WEDO-0302: Mix the base paint and curing agent in the specified ratio and stir evenly; then add an appropriate amount of filler (quartz powder, talc powder, etc.) at the ratio of paint: filler = 1: 0.1–0.5, and stir evenly.0.1
2. Trowel evenly with a trowel, focusing on filling defects such as pinholes and air holes; the number of construction passes can be adjusted according to the actual situation.
Copper Foil Laying1. Lay in a 2–3m × 2–3m "well" shape; the copper foil must be closely attached to the ground./
Troweled Conductive Layer1. Use WEDO-0402D: Mix the base paint and curing agent in the specified ratio and stir evenly.0.15
2. Trowel evenly with a trowel, focusing on filling defects such as pinholes and air holes; the number of construction passes can be adjusted according to the actual situation.
3. Test the resistance value after drying; the resistance value is required to be less than 2×10⁴ Ω.
General Heavy-duty / Anti-corrosion Anti-static Self-leveling Topcoat1. First trowel evenly with a trowel.0.9
2. Roller-coat after drying and treat with a defoaming roller.
3. Note: Applying a topcoat putty layer will increase the resistance value; it is not recommended to apply a topcoat putty layer for conductive products, and the topcoat should be directly troweled on the conductive layer.
Conductive Type / Anti-corrosion Anti-static TopcoatMix the base paint and curing agent in the specified ratio and stir evenly; dip the topcoat with a roller and apply evenly, ensuring uniform roller coating without missing coating.0.35


Notes

  • Paint application environment: Temperature 5 - 30℃, relative air humidity less than 80%. Excessive humidity will affect the strength and conductivity of the conductive layer, causing the paint to become white and lose gloss;

  • Before applying the conductive layer, the epoxy material must be used for repair and leveling;

  • The copper foil must be firmly bonded and must not warp or lift;

  • The conductive layer is applied in one coat. After scraping, ensure there are no omissions, the surface is smooth, without particles. After completion of the construction, the resistance value must be less than 2×104 Ω;

  • Conductive paint can be scraped with paint putty, but electrostatic dissipation paint cannot be applied with a paint putty layer;

  • The paint film must be dry before it has the ability to resist strong acids and strong alkalis;

  • If the anti-static paint layer needs to be reworked, the conductive layer must be re-applied; otherwise, the resistance value cannot meet the requirements;

  • There is a certain color difference between different batches of materials. When applying in the same area, the same batch of materials must be used. When placing multiple orders for the same project, it is necessary to indicate to adjust the color according to the sample.

Construction conditions

  • Air temperature: 5℃ – 30℃

  • Relative humidity: < 80%

  • Moisture content on substrate surface: < 8%

  • Dew point temperature: The substrate and uncurdled coating must be 3℃ or more higher than the dew point temperature to reduce the risk of condensation or frosting on the floor coating;

  • Dirty floors need to be thoroughly cleaned; otherwise, it may affect the even application of the coating.
