PMMA flooring is short for Poly methyl methacrylate flooring. It’s a type of resin widely used in industrial and commercial environments.
A PMMA floor is a protective flooring surface that is made up of various layers of acrylic resin, which usually include a primer, body coat and seal coat. It is a thermoplastic resin which softens once heated.
This allows the system to form a chemical bond between layers. PMMA floors are fully cured within two of hours installation, making them one of the fastest-curing resin flooring products available.
Types of Resin PMMA Floor
There are four main types of PMMA flooring available:
PMMA Floor Coating
Less than 2mm in depth a PMMA coating, is commonly found in industrial settings to provide an easy to clean, protective coating over the substrate.
PMMA Mortar Floors
A resin-rich mortar which can be mixed with aggregate to provide an extremely hardwearing finish. 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 PMMA floors
As suggested by its name, self-levelling PMMA floors are smooth systems that are typically 2mm – 4mm in depth. These generally have a matt appearance. These can be enhanced by adding a flake finish to the top to create a decorative appearance or broadcast with an aggregate to increase slip resistance levels.
Trowel applied PMMA floors
This type mixes a combination of resin and aggregate to provide a hardwearing smooth system, typically laid between 4-6mm in depth. The system can be broadcast with aggregate to increase slip resistance levels.
Advantages of PMMA Flooring
There are a variety of advantages to using resin PMMA flooring, these include:
- Fast curing (full cure within 2 hours)
- Highly aesthetic
- Excellent slip resistance
- Temperature does not affect curing period (between 35°C and -30°C)
- Chemical bond between layers and to substrates
- UV resistant
Disadvantages of PMMA Flooring
Equally, however, there are also some disadvantages to using resin PMMA flooring including:
- Strong odour
- Higher cost
- Heat tolerant up to 80°C
