Common Myths About Water-Based Epoxy Colored Sand Floor Paint Debunked: 5 Misconceptions to Avoid!

Myth 1: Water-Based Epoxy Colored Sand is Not Abrasion-Resistant and Will Flake Off After One Year

Truth: High-quality water-based epoxy colored sand floor paint has a surface hardness of 2-3H and an abrasion resistance coefficient ≥0.5g/1000 revolutions (national standard requirement ≤0.8g/1000 revolutions). With normal household use (average daily foot traffic ≤100), it can last 8-15 years and won't flake off after one year.

Causes of flake off: Most often due to purchasing inferior product (poor compatibility between colored sand and resin) or an imbalance in the ratio of colored sand to curing agent during application (too little curing agent), rather than inherent abrasion resistance of the water-based paint.

Verification Method: Ask the merchant for an "Abrasion Resistance Test Report" when purchasing, and supervise workers during application to ensure they mix the materials according to the product instructions.

Myth 2: Water-based epoxy floor paint is less durable than solvent-based epoxy floor paint.

Truth: The core difference between the two lies in the solvent, not durability. High-quality water-based epoxy floor paint  and solvent-based epoxy floor paint offer similar abrasion and compression resistance, but water-based paint is more environmentally friendly (lower VOC content) and more flexible (elongation at break ≥20%, compared to approximately 10% for solvent-based flooring). It is also less susceptible to cracking due to temperature fluctuations, making it suitable for colder northern regions.

Myth: Some people believe that "solvent-based flooring has a stronger odor = more durable." In reality, the strong odor is due to the presence of large amounts of organic solvents and has nothing to do with durability.

Myth 3: Floors become slippery in rainy weather, making them unsafe for the elderly and children.

Truth: Water-based epoxy floor paint contains inherent colored sand particles with an anti-slip coefficient of ≥0.5 (the national standard requires ≥0.5 for public spaces and ≥0.4 for homes). When water accumulates on rainy days, the gaps between the particles allow water to escape, making it more slip-resistant than smooth ceramic tiles (with an anti-slip coefficient of approximately 0.3). Slippery Causes: Selecting fine sand (<0.3mm) with glossy topcoat (surface too smooth), or greasy floor stains (greasy floor stains reduce the anti-slip coefficient).

Solution: For homes and public spaces, prefer medium sand (0.5-1mm) with matte topcoat, and clean the floor regularly.

Myth 4: The space needs to be ventilated for 3 months after construction before moving in.

Truth: High-quality water-based epoxy colored sand floor paint has a VOC content of ≤100g/L, has no noticeable pungent odor during construction, and releases ≤0.03mg/m³ (formaldehyde) after curing (7 days). Ventilation is sufficient for 7-15 days before moving in, eliminating the need for a "3-month ventilation" period.

Source of Misconception: Confusion between "water-based paint" and "solvent-based paint." Solvent-based epoxy floor paint, due to its high VOC content (≥300g/L), requires 1-3 months of ventilation, while water-based paint does not. Verification method: Test with a formaldehyde detector after construction. If the readings meet the standard, you can move in.

Myth 5: The brighter the color, the less environmentally friendly it is.

Truth: The environmental friendliness of water-based epoxy colored sand floor paint depends on the resin purity and solvent content, not the color. High-quality, bright colors (such as red and blue) use inorganic pigments (which are environmentally friendly and non-toxic), and their VOC content can also be ≤100g/L. Low-quality, light-colored paints that contain organic solvents will also fail to meet environmental standards.

Avoidance method: Regardless of the color, always check the environmental test report (focusing on VOC, formaldehyde, and heavy metal content) rather than judging based solely on color.
