Duco Paint vs PU Paint: What You Need to Know Before You Choose
If you are planning to repaint furniture or give old metal surfaces a new life, you already know there are many paint types to choose from. Two names come up all the time. Duco paint and PU paint. Both look great. Both last long. And both promise a good finish. Still, they perform very differently once applied.
This guide breaks everything down in a simple, friendly way, so you can pick the right product for your project without second-guessing.
Let’s get into it.
What Is Duco Paint?
Duco paint is a nitrocellulose-based coating. People love it for its smooth and glossy surface. It also dries very quickly and has been used in the automotive world for decades. Cars finished with Duco have that shiny, polished look that you usually associate with classic models.
Inside the home, Duco is commonly used on wooden furniture. It works well on pieces that need a crisp, even surface. Duco brings out the natural look of wood and helps brighten up older furniture without hiding its character.
It also performs nicely on metal. If you have metal shelves or decor items and want a clean and modern surface, Duco can give you that look.
If you want ready-made Duco-finish options, Asian Paints offers spray and finishing solutions through their workshops and painting services. Their trained teams can deliver a factory-like Duco finish on cabinets, tables and other interior furniture.
What Is PU Paint?
PU stands for polyurethane. This paint is known for being tough, resilient and long-lasting. It is a two-part system, which means you mix a resin with a hardener before application. Once cured, it forms a strong shield that resists scratches, chemicals and heavy use. That is why PU coatings are preferred in industrial settings, commercial buildings and airport hangars.
Architects also choose PU for steel and concrete because it stands up well to harsh weather.
On wood, PU gives a rich, smooth and luxurious finish. It lasts longer than Duco and maintains its colour for years. PU also works beautifully on metal, plastic and even glass.
Asian Paints has several polyurethane products within its luxury interior and wood finish ranges. Their WoodTech PU line is popular for cabinets, wardrobes and premium wooden furniture. If you ever need a perfect application without mistakes, the Asian Paints Safe Painting Service is a reliable choice. Their applicators are trained specifically for PU finishing.

Where Each Paint Works Best
Duco paint is ideal for wooden furniture that needs a clean, polished look without a large budget. It is also great for metal decor pieces, small cabinets and old furniture that you want to refresh quickly.
PU paint is the better choice when surfaces face tough conditions. That includes sunlight, heat, moisture or frequent handling. Think kitchen cabinets, wardrobes, bathroom vanities and outdoor furniture.
PU is also excellent for high-end furniture where you want a premium finish that lasts for many years.
Asian Paints WoodTech range includes PU finishes, sealers and polishes designed exactly for these kinds of long-term projects.
How to Decide Between Duco and PU
Here are the main factors to think about when choosing between the two.
Cost
If you want a good finish without stretching your budget, Duco is a dependable option. It gives you a bright, neat surface at a lower cost. PU is more expensive, but the finish has a premium feel. Asian Paints offers both types in different price brackets, so you can pick something that fits your plan.
Longevity
PU clearly lasts longer. It handles sunlight better, retains colour and resists scratches. Duco is still durable, but it may show yellowing over time. If your project is a long-term one, PU wood coatings from Asian Paints give you the most value.
Location
Kitchens, wardrobes, bathroom storage and high-touch furniture benefit from PU. It handles moisture, heat and friction better. For decorative pieces or furniture used lightly, Duco works perfectly.
Safety
Duco is more flammable. PU is safer once cured. In areas like kitchens, PU finishes from Asian Paints are often the preferred choice.
