Are you planning to install a resin cast floor yourself, but still unsure whether to choose an epoxy or a polyurethane (PU) floor? Then you’re in the right place. Both floor types are popular due to their sleek appearance, seamless finish and durability, but there are also important differences that determine which floor best suits your situation.
In this article, we clearly explain the differences so you can make the right choice for your project.
What is an epoxy cast floor?
An epoxy cast floor is a hard, seamless floor with exceptionally high strength. It is resistant to heavy mechanical and chemical loads, which is why these floors are widely used in workshops, warehouses and industrial environments.
Key properties of epoxy floors:
- Extremely strong and impact-resistant.
- Waterproof and chemically resistant.
- Sleek, high-gloss finish.
- Highly wear-resistant.
- Non-elastic.
- Moderate UV-resistance.
- Suitable for underfloor heating.
What is a PU cast floor?
A PU cast floor (polyurethane) is a flexible, comfortable flooring system often used in living spaces and offices. The floor feels warm and soft underfoot, making it ideal if you walk barefoot or want to reduce noise.
Key properties of PU floors:
- Slightly elastic.
- Comfortable and sound-damping.
- UV-resistant.
- Less suitable for heavy loads.
- Very suitable for living spaces.
- Suitable for underfloor heating.
