Although oil-based floor paint has excellent performance, its environmental issues are becoming the main bottleneck of development. The following is an analysis of its challenges and transformation directions:

1. Environmental shortcomings: VOC and health risks

Oil-based paint uses toluene and xylene as solvents, and releases a large amount of irritating odors and harmful gases (such as formaldehyde) during construction. Long-term exposure may cause respiratory diseases. A typical case is that the garage of a residential community in Shenzhen used solvent-based floor paint, which caused collective discomfort to the owners and was eventually forced to replace it with water-soluble paint.

2. Policy restrictions and market shrinkage

Many places have issued policies to restrict the use of solvent-based paints (such as Shenzhen’s ban since 2015), pushing the industry to transform to water-based paint. The flammability of oil-based paint also increases storage and transportation risks.

3. Alternatives: The rise of water-based paint

Water-based paint uses water as a solvent, has extremely low VOC emissions, and has a hardness of up to 4H (higher than 2H for oil-based paint), achieving a balance between wear resistance and environmental protection. Some construction teams adopt the "water-bottom oil-surface" strategy to combine the advantages of both to reduce costs.

4. The future of oil-based paint: technical improvement and scene segmentation

Low-VOC formula research and development: Develop products that meet the new national standards by reducing the proportion of harmful solvents;

Special scene retention: such as extreme wear resistance requirements or temporary projects, still relying on the performance advantages of oil-based paint

As a traditional floor coating, oil-based floor paint still occupies an important position in specific fields due to its unique properties. The following is an analysis of its core advantages and applicable scenarios:

1. Excellent physical properties

Due to the addition of organic curing agent, the paint film hardness of oil-based floor paint can reach a high level (such as 2H standard), and its wear resistance and compression resistance are particularly outstanding, which is suitable for heavy-duty industrial areas such as logistics warehouses, mechanical workshops, etc. Its high-gloss surface can also enhance the beauty of the floor and is suitable for commercial spaces that require visual effects.

2. Mature technology and construction experience

After years of development, the construction process of oil-based paint has been widely mastered. Experienced construction teams can complete the coating quickly and have more flexibility in handling complex base surfaces.

3. High cost-effectiveness

In terms of material cost, oil-based paint is usually lower than water-based floor paint, especially the topcoat part. For projects with limited budgets and low environmental requirements, oil-based paint is more economical.

4. Stable chemical resistance

Oil-based paint has strong tolerance to oil and chemical solvents, and is suitable for environments that are easily exposed to corrosive substances, such as auto repair shops and chemical plants.

5. Irreplaceable application scenarios

Although environmental protection policies are becoming stricter, oil-based paint is still irreplaceable in the following scenarios:

Environment with high humidity or large temperature difference: Oil-based paint has strong penetration and can adapt to some wet base surfaces.

Short-term high-frequency use requirements: such as temporary exhibition halls or rapid renovation projects, because it can be put into use after drying.

 

 

 

The construction of water-based epoxy floor paint requires steps and details, and standardized operation can create a high-quality floor. Before construction, the base needs to be fully treated. First, use a grinder to grind the floor to remove defects such as sanding and hollowing, so that the base is flat and has a certain degree of roughness to facilitate subsequent attachment. At the same time, sweep and vacuum to ensure that there is no dust or oil residue on the ground.

 

When applying waterborne epoxy floor paint primer, mix the waterborne epoxy floor paint primer evenly according to the proportion and apply it evenly with a roller or spray gun. The primer can enhance the adhesion between the ground and the topcoat. The application should ensure that there is no omission. The drying time depends on the ambient temperature and humidity, and generally takes 8-12 hours.

 

Then proceed with the mid-coat construction. Add an appropriate amount of quartz sand to the water-based epoxy mid-coat material and stir it. Use a trowel to scrape it to increase the strength and thickness of the floor. You can scrape it 1-2 times as needed, and polish it flat after each coat dries. Finally, the topcoat is applied. Roll or spray the prepared water-based epoxy floor paint evenly. Pay attention to the speed and strength during the operation to ensure that the paint surface is uniform and smooth. The topcoat gives the floor beauty and wear resistance. After completion, it needs to be maintained for 3-7 days. During this period, avoid heavy objects hitting it and sharp objects scratching it. After it is completely cured, it can be put into use.
