Polyurethane topcoat
- Product Description
Product Overview
The polyurethane topcoat (product model: AD-190#-3) launched by Shaanxi Andi Floor Decoration Engineering Co., Ltd. is a high-performance coating specifically designed for outdoor environments. It is developed with polyurethane as the core material and advanced technology. The product boasts excellent weather resistance and UV resistance, effectively protecting the coating from erosion by complex outdoor climatic conditions and ensuring long-term use without fading or cracking. Its 24kg specification design meets the needs of large-area construction and is suitable for scenarios such as sports courts, stands, and ground graffiti, making it an ideal choice for outdoor floor decoration and protection.
Main product features
1. Excellent weather resistance
It adopts an outdoor weather-resistant material formula, capable of withstanding extreme temperature variations ranging from -30℃ to 60℃, adapting to harsh climates such as rain, snow, sandstorms, and intense sunlight, ensuring a service life of over 10 years for the coating.
2. Highly effective UV resistance
The addition of high-concentration ultraviolet absorbers effectively blocks 99% of UV radiation, preventing chalking and discoloration of the coating caused by photoaging, and maintaining long-lasting and vibrant colors.
3. Super strong adhesion
It forms chemical bonds with substrates such as concrete, asphalt, and metal, with the coating adhesion reaching the national standard Grade 1, thus avoiding issues of peeling and detachment.
4. Environmental protection and safety
It has passed SGS environmental certification, with a VOC content of less than 150g/L, no heavy metals added, and no pungent odors during construction and use, meeting national environmental protection standards.
5. Wear-resistant and impact-resistant
The surface hardness reaches 3H (pencil hardness), capable of withstanding high-intensity friction and impact, suitable for public areas with heavy foot traffic.
6. Easy to clean and maintain
The coating surface is dense and smooth, making stains and dust difficult to adhere to. It can be restored to cleanliness simply by rinsing with clean water, reducing long-term maintenance costs.

Scope of application
1. Outdoor sports venues
It is suitable for coating the surface layers of plastic runways in basketball courts, tennis courts, badminton courts, etc., providing a slip-resistant and shock-absorbing elastic surface to enhance sports safety and comfort.
2. Public facilities stand
The coating applied to the stand areas of schools, gymnasiums, amphitheaters, etc., features resistance to trampling and ultraviolet rays, ensuring long-term use without fading and enhancing the spectator experience.
3. Ground creative graffiti
It provides a high-adhesion substrate for parks, squares, and cultural blocks, supporting the creation with materials such as acrylic paint and epoxy colored sand, and enhancing color durability by more than three times.
4. Industrial and Commercial Spaces
Ground protection in areas such as logistics parks, parking lots, and factory workshops to resist chemical corrosion and heavy-load wear, thereby extending the service life of the base material.
5. Exterior wall decoration of buildings
As a protective coating for concrete and metal curtain walls, it replaces traditional fluorocarbon paint, reducing overall costs by 30% and improving construction efficiency by 50%.
Frequently Asked Questions (FAQ)
Q1: What are the differences between polyurethane topcoat and epoxy floor paint?
A: Polyurethane topcoat has far better weather resistance than epoxy paint and is suitable for outdoor use; epoxy paint is more suitable for indoor high-wear-resistance scenarios. The flexibility of polyurethane can better accommodate the thermal expansion and contraction of the substrate, preventing cracking.
Q2: What are the requirements for ambient temperature during construction?
A: The recommended construction temperature is 5-35°C with humidity ≤85%. Low temperatures can slow down drying, while high temperatures may cause pinhole blistering. Construction should avoid rainy days and strong wind conditions.
Q3: How to calculate the amount of paint needed?
A: Theoretical usage = area × coating rate × number of coating layers. For example: For a 1000㎡ court coated with 2 layers, the usage = 1000 × 0.2 × 2 = 400 kg, requiring 17 barrels of 24 kg products (including wastage).
Q4: What factors affect the lifespan of the coating?
A: It mainly depends on substrate treatment, construction techniques, and the operating environment. If the substrate moisture content exceeds 8%, lacks primer treatment, or is exposed to strong acids or alkalis for prolonged periods, its lifespan will be significantly shortened.
Q5: Can I directly apply the coating over the old one?
A: Assess the adhesion of the old coating: If the peeling or detachment area exceeds 30%, it is necessary to completely remove it and grind it down to a solid substrate; if it is in good condition, the construction can proceed directly after applying an interface agent.
Q6: Does the product support custom colors?
A: We support color matching based on RAL and Pantone color charts, with a minimum order quantity of 200 kg (approximately 8 barrels), and the customization cycle will be extended by 3-5 working days.
Q7: How to store unused paint? A: Unmixed base paint and curing agent should be sealed and stored separately to prevent moisture contamination. Mixed paint must be used up within 4 hours, as it will cure and become ineffective beyond this period.
