The difference between PU and epoxy cast floors
Thinking about a cast floor? You'll often come across two types: PU (polyurethane) and epoxy. Both are sleek, seamless, and modern, but they have distinct differences. Below, you'll find everything you need to know to make the right choice. Romar-Voss Floor Systems is here to help with expert advice and craftsmanship.
Different materials
PU is short for polyurethane, which is an elastic synthetic material. Epoxy is a mixture of resin and a hardener, resulting in a very rigid material.
PU is flexible and soft to the touch, while epoxy is firm and cold. Each type of floor has its own unique characteristics.
Comfortable
A PU poured floor feels warm and is comfortable to walk on, even barefoot, as it has a slight spring to it.
Epoxy feels hard and is not flexible, which can be perceived as uncomfortable.
Sound and acoustics
PU floors dampen sound, creating a quieter environment. You'll hear less foot traffic, and the echo is reduced.
Epoxy floors do not absorb sound. Sound bounces back, which can be disruptive in a home. For offices or healthcare facilities, PU is often the better choice.
Durability and wear resistance
Epoxy cast floors are incredibly strong and can withstand heavy use from things like machinery, vehicles, and chemicals.
PU floors are less scratch-resistant but are less likely to crack. They flex with the subfloor, which is useful for new construction or renovations.
Heat and underfloor heating
PU conducts heat well, so you'll feel the warmth from underfloor heating quickly. This makes it an excellent choice for homes. While epoxy also conducts heat, it still feels cold to the touch. This makes PU a better option for living comfort.
Appearance and ambiance
PU floors have a soft, matte finish that creates a cozy, homely feel. They are available in a wide variety of colours.
Epoxy floors are glossy and sleek, giving them an industrial look. Both types can be finished to resemble concrete.
Ideal applications
PU poured floors are often found in homes, offices, or healthcare facilities where comfort and safety are priorities. Epoxy is better suited for warehouses, garages, and workshops, where durability is more important than comfort.
Cleaning and maintenance
Both floors are easy to clean because they are seamless, which prevents dirt from accumulating.
PU floors require a little more care; for instance, using felt pads under furniture is recommended. Epoxy can withstand heavier loads but may lose its shine over time.
Sustainability and health
Many PU floors are solvent-free, which is better for you and the environment as they don't emit harmful fumes during installation. Epoxy often contains solvents, so good ventilation is essential during installation.
Installation
Installing both types of floors requires professional expertise. PU is more sensitive to moisture and temperature, so its application requires a skilled hand.
Epoxy cures quickly and is a chemical process that also demands precision. Romar-Voss Floor Systems ensures a professional installation for both.
Which floor is right for you?
If you live in a house or apartment, PU is a better fit. It’s comfortable, quiet, and warm. For a garage, workshop, or warehouse, epoxy is often a smarter choice due to its strength and durability. We are happy to help you choose.
