Yongrong Floor Repair Paint is a specialized repair material developed for various flooring types, including concrete, epoxy, and ceramic tile, addressing issues such as cracks, potholes, and sandblasting. It restores the functionality and aesthetics of the floor through high-strength adhesion, wear resistance, and impermeability. The following provides a comprehensive overview of Yongrong Floor Repair Paint, from its product system and technical parameters to application specifications:
I. Product Introduction
Yongrong Floor Repair Materials are based on resin-based (epoxy, polyurethane), cement-based, and composite modified materials, combined with aggregates and additives to form repair solutions suitable for various scenarios. Its core functions include crack sealing, pit filling, structural reinforcement, and surface strengthening. It is suitable for industrial plants, commercial spaces, and home garages, and features both rapid curing (surface dry in 2-4 hours) and long-term durability (over 20 years of aging resistance).

1.High adhesion: The adhesion strength to substrates such as concrete and epoxy is ≥1.5MPa, preventing secondary detachment.
2.Wear-resistant and impermeable: wear loss ≤0.3kg/㎡, penetration depth ≤5mm, resists the erosion of water and chemical media.
3.Environmentally friendly and safe: Low VOC formula (≤100g/L), some products are FDA certified, suitable for sensitive places such as food factories.
Yongrong Floor Repair Paint offers targeted repair solutions, covering a variety of application scenarios:
Industrial applications : Cracks in factory floors (0.2-5mm), pits in equipment foundations, and chemically corroded areas (such as chemical plants and laboratories).
Commercial sector : Repairing issues such as sandy floors in shopping malls, worn parking lot ramps, and uneven showroom floors.
In the residential sector : repairing cracks in home garages, damp-proofing basement floors, and repairing hollow tiles on terraces.
Special scenarios : bridge expansion joints, airport runway potholes, and nuclear power plant radiation protection ground repair.

IX. Product Storage
Storage conditions: Store in a cool, dry place at a temperature of 5-35℃, away from direct sunlight.Shelf life: 12 months for epoxy/polyurethane materials, 6 months for cement-based materials.
X. Base Surface Treatment
1.Base layer requirements: dry (moisture content ≤8%), free of oil stains and loose particles, and cracks must be cut into V-shaped grooves (depth ≥5mm).2.Processing steps:
Grinding: Use a grinder to remove laitance and increase surface roughness;
Cleaning: Use a high-pressure water gun to rinse or a vacuum cleaner to remove dust;
Apply an interface agent: epoxy primer (0.2kg/㎡) to enhance adhesion.
XI. Recommended Construction Product System
(I) Crack Repair System1.Fine cracks (≤0.5mm): Low viscosity epoxy grout (A:B=5:1), surface smoothed after pressure grouting.
2.Wide cracks (>0.5mm): Epoxy mortar (with added quartz sand) is used for layered filling, with each layer ≤10mm.
(II) Pothole Repair System
1.Shallow pits (≤10mm): Cement-based self-leveling mortar, pedestrians can walk on them 24 hours after automatic leveling.
2.Deep pits (>10mm): Epoxy mortar + quartz sand, filled in layers and compacted by vibration.
XII. Construction Guidelines (Instructions for Use)
1.Material mixing : Weigh the two-component materials according to the proportion (error ≤ ±2%), and mechanically stir for 3-5 minutes until uniform.2.Construction tools : grouting pump (for cracks), trowel (for mortar), grinder (for surface treatment).
3.Construction steps :
Cracks: Drilling → Grouting → Curing → Grinding;
Potholes: Cleaning → Filling → Compacting → Curing.
XIII. Precautions
1.Environmental control: Temperature 5-35℃, humidity ≤85%, avoid construction on rainy days.2.Material usage: The mixture should be used within 30-60 minutes after mixing to avoid curing and waste.
3.Finished product protection: Do not step on it during the curing period; it can bear weight after 7 days.
XIV. Application Tools
Essential tools : grouting pump, trowel, grinder, hygrometer, thermometer.Auxiliary tools : masking tape, measuring cup, electronic scale.
XV. Safety Precautions
1.Protective measures: Wear gloves and goggles, and ensure ventilation during construction.2.Waste disposal: Solidified waste materials are recycled as construction waste, while unsolidified materials must be stored in sealed containers.
3.Emergency treatment: Wash skin with soap and water; rinse eyes immediately with water and seek medical attention.
