A resin floor lining is a build-up of resinous materials applied to an existing subbase and therefore an excellent way to protect floors against all physical, mechanical, thermal, and chemical wear.

Different resin types offer a variety of solutions based on the application characteristics and in-service performance of the materials. The resin selected is vital in the planning, design, and construction phase, as it will affect the longevity, performance, and aesthetical appeal of the floor.

Specification framework

Deciding on the contractor is just as important as deciding on which resin system will suit the application type best, and it is always recommended to make use of an approved or recommended contactor from the material supplier.

It is essential that there is a consultation between the client, manufacturer and the specialist flooring contractor beforehand. This will ensure that ambiguities in the process may be prevented prior to ending up with a result that is substandard and or the client’s expectation not met.

Functional needs

There are several functional requirements for floors in numerous different structures that need to be clarified beforehand to decide on the best product or system:

• Mechanical wear.
• Thermal conditions.
• Chemical attack (occasional or continuously submerged).
• Slip resistance.
• Abrasion resistance.
• Impact resistance.
• Ease of cleaning.
• Ultraviolet (UV) resistance.
• Life expectancy.

Substrate condition

Before proceeding with the installation, the contractor must inspect the floor by testing the substrate conditions and ensure that the substrate is in good condition. A general comment or rule in the flooring community is as follows, “Any flooring system is only as good as the substrate being applied to and the preparation thereof.”

This involves testing:

• Tensile strength of the substrate.
• Levels of the substrate (within tolerances and if not, what rectification is required).
• Contamination (type and remedial action thereof).
• Moisture content of the substrate suitable to the selected system.
• Joint construction on new floors, or maintenance of joints if the substrate is existing.

Other considerations

Other factors to keep in mind in the specifying process include:

• Program and time considerations / constraints including return to service timelines.
• Aesthetic requirements.
• Budget constraints.
• Technicality of the application of the selected system.
• Product options and system requirements.

Application type

Depending on the type of flooring system selected (sealing, coating, or comprehensive solutions), there are numerous areas of application:

• Warehousing.
• Food and beverage manufacturing or processing facilities.
• Retail.
• Offices spaces.
• Hospitals.
• Storage facilities.
• Production facilities and factories.
• Pharmaceutical industry.

As always suggested, contact your flooring manufacturer for expert advice on the best product for your new or refurbishment project.
