Water-based epoxy colored sand self-leveling floor paint

Issue 1: Surface Wrinkles and Bubbles After Application  Cause Analysis: ① The base layer moisture content exceeds the standard (>8%), causing evaporation and bubbles after application; ② The colored sand and curing agent are not mixed evenly, resulting in trapped air; ③ The application temperature is too low (<10°C), resulting in a slow curing process and wrinkling.  Solution:  Small Area (<10cm²): After the floor is fully cured (7 days), use a utility knife to open the bubbles and remove any impurities. Fill the gaps with a water-based epoxy repair agent and the same colored sand. After drying, sand the surface smooth and apply a topcoat.  Large Area: If the area with bubbles or wrinkles exceeds 10% of the total surface area, remove the floor, reapply two coats of moisture-proof primer to the base layer, and then apply the standard process.  Issue 2: Color variation after curing, with areas showing varying shades.  Cause Analysis: ① Mixing different batches of colored sand during construction (natural colored sand has slight color variations between batches); ② Uneven application of topcoat, resulting in darker areas with thicker coating; ③ Significant color variation in the base layer (e.g., areas previously painted), causing color variation due to color bleed-through.  Solution:  Minor color variation (not noticeable to the naked eye): Apply a coat of epoxy wax to the entire surface, using the wax's covering power to minimize the color variation.  Significant color variation: For lighter areas, apply a thin coat of diluted topcoat of the same color (diluted with water in a 1:1 ratio, applied thinly). After drying, compare the colors until they are consistent with the surrounding areas.  Issue 3: Delamination at edges or corners after six months of use.  Cause Analysis: ① Edges, such as corners and doorways, were not reinforced, resulting in delamination from prolonged foot traffic and friction; ② Primer was not applied to the edges during construction, resulting in poor adhesion; ③ Ground subsidence caused cracks in the base layer, leading to delamination. Solution: Local delamination (small area): Scrape off the delamination, sand the base, and apply a coat of primer. Fill the gap with water-based epoxy putty and sand of the same color. After drying, apply a topcoat. Mask the edges with masking tape to ensure a clean line.  Delamination caused by cracked base: First, repair the cracks in the base (using cement mortar). After drying, repair the floor according to the above steps.  Issue 4: Colored sand particles have fallen off, leaving "pits" on the surface.  Cause Analysis: ① The purchased colored sand has poor compatibility with the resin (low-quality colored sand has an uneven surface, making it difficult to bond with the resin); ② The ratio of colored sand to curing agent was incorrect during application (too little curing agent, so the resin was not fully cured); ③ Prolonged friction with sharp objects caused particles to fall off. Solution: Small pits: Use a toothpick to apply a small amount of water-based epoxy glue and fine sand of the same color to fill the pit. After drying, sandpaper to smooth the gap.​ Large areas of loose particles: Partially scrape away and then reapply the middle layer of colored sand. Choose colored sand from the same brand and batch as the original product to avoid compatibility issues.

1. Daily Cleaning: "Be Gentle" to Avoid Damaging the Grain Texture  Tools: For daily dusting, use a soft broom or dust mop (avoid hard-bristled brushes, which can diminish the surface gloss). Mop with a well-wrung cotton mop or microfiber cloth (moisture content ≤ 30% to prevent water from seeping into the gaps between the colored sand).  Cleaning Agents: Use only neutral detergents (such as dishwashing liquid or neutral floor cleaner) diluted before use. Avoid using strong acids (such as toilet cleaners) or strong alkalis (84 disinfectant), as they can corrode the surface resin layer, exposing the colored sand and causing discoloration.  Cleaning Frequency: For residential spaces, dust and mop once or twice a week. For commercial spaces (such as cafes and shopping malls), dust daily and mop every other day to prevent dust from accumulating and embedding in the gaps between the colored sand.  2. Avoid "Hidden Damage": These actions shorten the lifespan of the floor.  Sharp Object Protection: Use rubber protective pads on furniture legs to prevent scraping when dragging chairs. Avoid scratching with sharp objects such as knives and keys. If shallow scratches occur, lightly sand with 1000-grit sandpaper and then wax to repair them.  Heavy Object Impact Taboos: Avoid parking overweight vehicles (such as trucks weighing over 5 tons) on garage floors for extended periods of time. When moving heavy items such as refrigerators and pianos around the home, use wooden planks or a cart to prevent excessive localized pressure that may cause cracking.  High-Temperature Protection: Place hot items such as freshly cooked pots and electric heaters on an insulating mat (epoxy flooring can withstand temperatures ≤ 80°C; temperatures above this limit will soften and discolor). Protect balcony floors from direct sunlight (install sunshades to prevent the colored sand from fading due to prolonged exposure).  3. Regular "Refreshing Maintenance": Keep the Floor in Top Condition  Waxing Maintenance: Apply epoxy wax every 6 months (for homes) or 3 months (for commercial spaces). Apply evenly with a waxing machine and then polish. This not only enhances the gloss, but also forms a protective film on the surface, reducing wear.  Crevicular Cleaning: The tiny gaps between colored sand particles can easily harbor oil and dust. Gently scrub with a toothbrush and a neutral detergent, then wipe dry with a damp cloth to prevent long-term accumulation of stains that can cause "blackening."  4. Special Scenarios Maintenance: Address Targeted Pain Points  Kitchen Floors: After each meal, wipe away grease around the stove to prevent it from seeping through. Deep clean the floor monthly with a neutral detergent, focusing on joints and corners.  Garage Floors: Before parking your vehicle on snowy days, clear snow and sand from the tires to prevent melted debris from scratching the floor. Check the drains regularly to prevent water from soaking the edges of the floor.  5. Regular Inspections: Early Detection and Addressing Problems  Perform a comprehensive inspection every three months, focusing on areas prone to wear such as corners, doorways, and under furniture.  If small areas of delamination (less than 5cm in diameter) occur, promptly fill them with a mixture of water-based epoxy repair agent and sand of the same color. After drying, sand them flat.  If areas of discoloration occur, contact the original contractor to obtain sand from the same batch and apply a topcoat to prevent further color discrepancies.
