How to Prime Resin Flooring

A resin floor is a hardwearing plastic surface that is created by mixing together a selection of ingredients to initiate a controlled chemical reaction that produces the desired finished product. Resin floors are a popular choice for industrial environments as they are durable and easy to maintain.

The type of resin used can vary and can be based on the specific requirements of a particular environment. This can include a focus on aesthetics, durability or chemical resistance. Typically, the more durable a resin is, the better it will be at resisting abuse and retaining its strength and appearance.

Most resin floors can be customised to meet the needs of an individual space, and there are many different colours available to choose from. This can be an important factor for a business as it helps to create a more appealing environment. Additionally, some floors are designed to be anti-slip, which is an additional benefit that can improve safety in busy workplaces.

During installation, it is important to ensure that the substrate is ready for the resin to be applied. It should be free from any contamination, friable materials or laitance. In addition, the subfloor should be structurally sound and achieve 26N/mm2 compressive strength to BS 8204 Part 1 (see Altro or FeRFA’s Guide to the Specification and Application of Synthetic prime resin flooring for further guidance).

Prior to applying any priming product, it is vital that the concrete floor is swept and vacuumed thoroughly. This removes any debris that may be stuck to the substrate, affecting adhesion. Any paint or coatings must be removed using an abrasive machine or soda blasting before the primer can be applied. Ideally, the floor should be stored in a dry, frost-free environment, preferably between 15degC and 20degC until it is ready for application.

It is also important to remember that different products will dry at varying rates. This is particularly relevant for priming. For example, epoxies can be very fast drying and should only be used in environments where the work will be completed quickly. Slower-drying products, such as polyaspartic or methyl methacrylate (MMA) resins, can be more suitable and provide greater working time, which is useful for larger projects.

When applying any primer, it is essential to follow the manufacturer’s instructions. It is also essential to ensure the application is carried out in a well-ventilated area, which will help to avoid moisture vapour build-up on the substrate. This can affect the finish, adhesion and surface quality.

Once the primer has been applied, it is then important to allow the floor to cure properly. This is usually achieved by ensuring good airflow and ventilation, but a specific curing regime should be discussed with the manufacturer for the chosen system.

After the floor has cured, it can be trafficked immediately, providing the correct maintenance regime is followed to prolong its life. A floor that has been correctly designed and adapted for its use should be expected to last at least ten years, although this may be reduced where the floor has been value engineered in order to meet budget or time constraints.
