One-component water-based penetrating sealant
Product Details
Product features
Shrink the pores of concrete and effectively prevent external pollutants from entering the concrete.
Enhance the surface hardness, wear resistance and compressive strength of both new and old concrete floors;
It can prevent the infiltration of carbon dioxide and moisture, inhibit the neutralization of concrete and prevent the corrosion of steel bars
It can prevent concrete from peeling and cracking and has excellent dust-proof performance.
The treated floor will have a marble-like luster. The longer it is used, the better the luster and the more beautiful the appearance. It is convenient for cleaning and sweeping, and saves maintenance and management costs.
Scope of application
It is particularly suitable for industrial plants and underground garages in industries such as electrical appliances, electronics, machinery, food, medicine, chemicals, tobacco, feed, textiles, clothing, furniture, plastics, and cultural and sports goods.

Notes
The penetrating sealant can only be applied to the concrete floor when it reaches the curing period.
For old floors, surface coatings (such as wax layers, curing agents, resin-based paints, etc.) and oil stains should be removed first. For floors with severe oil stains, appropriate treatment is required before the application of penetrating sealant.
After the application of the penetrating sealant, it needs to be dragged in time. Water can be sprinkled to dilute it and help with penetration.
Excess penetrating sealant should be cleaned up in time to avoid causing the ground to turn white.
It can be ground and polished to a certain mesh size according to the required effect.
Construction workers should have good protective measures. If this product comes into contact with the skin, eyes, etc., it should be washed immediately with clean water.
Construction conditions and base material preparation should be strictly carried out in accordance with the product manual.
Technical Statement

| Construction Process | ||
| Process Name | Specific Methods and Requirements | Single Coat Usage (kg/m²) |
| Substrate Grinding | 1. Clear debris and dampen the floor | / |
| 2. Grind the floor with 50# metal grinding discs to remove laitance and debris | ||
| 3. Grind sequentially with 50# and 150# resin discs to eliminate rough grinding marks, fully open pores, and help the sealer penetrate into the concrete | ||
| 4. Clean the floor, dry completely, and prepare for sealer application | ||
| Applying Penetrating Sealer | 1. Spray WEDO-0903 penetrating sealer evenly on the floor surface, keep it moist for 2–4 hours; use a roller to push back and forth to assist absorption | 0.3 |
| 2. When the sealer thickens, spray appropriate water to dilute excess sealer, then roll back and forth for secondary absorption | ||
| 3. When the sealer thickens again, rinse off excess with clean water | ||
| Machine Polishing (Optional) | After the floor is fully hardened, polish it with 300# to 1000# resin discs using a polishing machine; polish to the required grit as needed | / |

Construction conditions
Air temperature: 5℃ - 30℃
Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating
