We explain exactly what is a Polyurethane Floor

What is a Polyurethane Floor?

Polyurethane flooring is a type of resin widely used in industrial environments and in particular food
and drink production facilities.

A polyurethane floor is a protective flooring surface made up of polyurethane resin and aggregate. It is a mix of resin and cement. It is a thermosetting resin which means the system irreversibly cures once hardened.

Types of Resin Polyurethane Floor

There are four main types of polyurethane flooring available:

Polyurethane Floor Coating

Less than 2mm in depth a polyurethane floor coating, is commonly found in industrial settings to provide an easy-to-clean, protective coating over the substrate.

Polyurethane Mortar Floors

Typically, a resin-rich granite-reinforced polyurethane repair mortar. These are used to repair damaged substrates and are suitable for areas that require higher levels of resistance to chemical attack or impact damage.

Self-levelling polyurethane floors

As suggested by its name, self-levelling polyurethane floors are smooth systems that are typically 2mm -4mm in depth. These generally have a matt appearance.

Flexible Polyurethane floors

An elastomeric polyurethane self-smoothing flow applied flooring typically laid at 2mm in depth.

With a degree of tolerance for structural subfloor movement, it can be beneficial for certain areas which require certain flexibility.

Polyurethane trowel applied floor

This type mixes a combination of polyurethane resin and white aggregate and is usually trowel applied. Typically installed between 6-9mm this system is very hardwearing and has a matt appearance with a slip-resistant profile. When the floor is first installed it has a uniform-coloured surface but with general use, the white aggregate will begin to show through.

Advantages of Polyurethane Flooring

There are a variety of advantages to using resin polyurethane flooring, these include:

  • Exceptionally hardwearing surface
  • Excellent heat resistance
  • Good surface abrasion resistance
  • Low odour
  • Cost-effective

Disadvantages of Polyurethane Flooring

Equally, however, there are also some disadvantages to using resin polyurethane flooring including:

  • Longer curing periods 5-7 days full chemical cure
  • The curing period is affected by the room temperature
  • They will not cure below 5°C
  • Susceptible to cracking with building movement
  • Not highly aesthetic
