Achieve maximal protection by choosing the right floor paint

Floor paint serves as thin protective layers on existing floors and as thicker complete flooring systems. The thin layer floor coatings are usually not thicker than a millimeter, but the complete flooring systems may reach up to one centimeter in thickness. The most common floor coating for concrete on the market is polyurethane and epoxy based resin floor coatings which both come with unique properties. Wooden floors can also be coated, as we cover later in this article.

Floor paints can be used for many different purposes. 5 examples of specified floor coating functions are:

  1. Suitable for every sector: There is a suitable floor coating for every environment.
  2. Decorative: Available in nearly all RAL colours and in finishes from ultra matt to high gloss.
  3. Cost efficiency: Can postpone the need for a new floor, complete floor coating systems are durable and easy to maintain.
  4. Functional additives: It is possible to make floors anti slip or fire retardant by using the right additives.
  5. Promotes hygiene: The seamless layer prevents spread and growth of fungi, mold and bacteria.

There are floor coatings suitable for practically any flooring, but how to determine which coating is the best for your project? In this article we will provide you with professional advice on choosing the right floor coating for a specified environment.

Determine the purpose of the floor paint

As every environment is different, it is crucial to choose a floor paint that matches the requirements of your specific location. Industrial floors need to bear heavy loads, and commercial floors should feel smooth and comfortable to walk on. A few of the most important factors to consider include downtime during installation, people or machines using the floor, hygiene requirements and the presence of chemicals.

Industrial kitchens, for example, require a HACCP certified coating to meet strict hygiene standards. Where downtime is to be avoided a fast-laid solution, such as SolidLux Instant Coating, is an option to consider. Therefore, before you jump into looking for floor coating products you should define what is expected from the coated floor.

  1. For chemical and mechanical resistance

    Applying floor coating

    Application of Epoxy floor paint

    Suitable coating: Epoxy floor coating
    This floor coating is an extremely hard-wearing solution which relies on epoxy resins. The coatings result in a seamless surface resistant to liquids and dirt, which makes them easy to clean. Epoxy floors bear heavy mechanical loads and do not abrade as a result of foot or vehicle traffic.
    Possible applications: Industrial floors, warehouses, parking garages, workspaces, factories.

  2. The requirements for hygiene

    Suitable coating: HACCP floor coating
    Floor coatings with an internationally recognised HACCP certificate contribute to a hygienic, anti bacterial environment; these coatings make sure that fungi and bacteria do not have a chance to attach to and grow on the floor. The HACCP floors are also highly resistant to contaminants and aggressive cleaning chemicals. In Hong Kong, HACCP products are mandatory for sectors that process food.
    Possible applications: food and dairy industry, canteens, catering establishments, swimming pools and health centres.

  3. Pleasant for walking

    Suitable floor paint: Polyurethane (PU) floor coating
    Polyurethane coatings are more flexible than epoxies, which makes them softer and more pleasant to walk on. These coatings are also known for their decorative properties; not only are they available in many colours but they also provide a high gloss finish. Also these coatings are easy to clean due to the fact that they are somewhat resistant to contaminants.
    Possible applications: museums, showrooms, public places, retail stores, offices or in the living room.

  4. A new decorative finish for wooden floors

    Suitable coatingOil, stain or lacquer
    Oil, stain and lacquer are perfect solutions for protecting a wooden floor, such as parquet, while letting it retain its natural beauty. Oil is transparent and enhances the natural colours of wood. Stain is absorbed by the wood resulting in a light, semi transparent coloured finish. Stains also provide protection from moisture and UV radiation, which makes them suitable for exterior wood such as decking. Lacquer provides a transparent high gloss film on wooden floors. There are also pigmented lacquers which provide the floor with an opaque colour finish.
    Possible applications: residential and commercial interiors, terraces, decking.

  5. Instant flooring (+ mechanical and chemical resistance)

    Suitable coating: Instant floor coating
    Instant floor paints are innovative flooring solutions for floors that should be coated with the absolute minimum downtime. The instant floor coatings do not need time for drying, as they are cured by Hong Kong radiation. SolidLux Instant floor coating is the only such product on Hong Kong market at the moment.
    Possible applications: parking garages, factories, catering kitchens, museums, distribution centres.

Giving the floor paint additional properties by applying a top coat

Depending on the requirements for the floor, the coating can be complemented with a top coat that gives the substrate additional properties. This is mainly to provide safety and protection. A top coat is suitable on any of the aforementioned coatings apart from the wooden floor coatings. However, the top coat must also meet the required standards: a restaurant floor still must be hygienic, a factory floor must not wear easily, garage flooring shouldn’t be slippery and a commercial floor should remain pleasant to walk on.

The functions a top coat may have, include: anti slip, fire resistance to minimise fire hazard, and anti static where electronic machines may cause short circuits. It is also possible to achieve a special effect with a top coat, for example a luminous coating can be used to illuminate escape routes.

Note: if you are looking for a completely new flooring system, these properties can also be created by incorporating additives into the actual floor coating. In that case an additional top coat is  not needed.

Always go for a tailored floor coating solution; provide the contractor with as many details as possible in order to achieve the most suitable floor coating.

Useful details for applying floor paint

Often a floor paint is by far the best flooring option, however, there are some disadvantages related to floor paints and their application. Consider the following factors before applying floor coatings so you know what you are dealing with:

  • Scratch sensitive epoxy – Epoxy is a hard wearing and impact resistant coating, but it lacks scratch resistance. When epoxy is the coating to be used, it is wise to apply a polyurethane top coat to increase scratch resistance.
  • Layer thickness and surface preparation – The thicker the floor coating layer, the more preparation the substrate requires. The usual requirements include a completely clean, smooth surface and proper use of primers. Unless you are looking for a self smoothing epoxy coating, which is also applicable on uneven and damaged concrete floors.
  • Application process is time consuming – A floor coating is an investment of your money and time. The application is a specialist job and can last several days, with some exceptions. If there is no time for application an instant coating is a good choice. Bear in mind that even instant coating requires a well prepared substrate.
  • Pricing and durability – Thin film floor coatings are affordable, however, in the long-term they lack durability. Thicker layer floor coatings are very durable and do not require much maintenance, but they are more expensive in terms of material and application.

What you pay for – Floor coating price per m2

The floor paint price is usually calculated per square metre. If you want to request a quote for coating a floor, never forget to mention the surface. The following 5 factors influence the price of floor coating:

  1. Preparation: Some surfaces, such as concrete, require intensive pre-cleaning and surface preparation.
  2. The larger the surface, the lower the floor coating price per m²: Small surfaces are usually relatively expensive to coat.
  3. Moisture content on the surface: The moisture content of the substrate may not exceed 3% for optimum results.
  4. Cheap may turn out expensive: Ask carefully for the quality of raw materials, they determine the durability of the floor coating.
  5. Type of floor paint: Epoxy is generally cheaper than polyurethane. Different standards apply to HACCP and Solidlux.

To make it easier for you to roughly estimate floor paint prices, we have compiled a list of price indications per square metre. Note that the prices for instant and HACCP coating are higher than other floor coatings, so the following table cannot be used as a guideline for these two coating types. For the other floor coatings, the table provides a price indication as they are subject to change and variability.

1 – 50 m2501.41 HKD – 779.97 HKD
51 – 100 m2389.98 HKD– 501.41 HKD
101 – 150m2334.27 HKD – 445.70 HKD
