As the best concrete experts in Singapore, epoxy is one of our favourite things to work with. As stylish and adaptable as it is long-lasting and durable, this finish looks great in almost any room, from a cosy living room to a stylish showroom.

But can you glue cement to a wooden floor? Of course. A clear epoxy finish is a great way to protect wooden floors or cover up old wood floors to make them more useful. For example, you could put new epoxy flooring in your shed to protect it.

There is a catch. Putting on an epoxy covering on wood that is wet and full of air is very difficult. It is possible to do, but you need to pay close attention to every detail, so it’s best to let a professional do it.

We’ll talk about the pros and cons of an epoxy wood floor finish in this guide, as well as the exact steps you need to take to put one down. You’ll see that unless you’re a skilled DIYer, protecting your hardwood floors is probably a job best left to the pros.

Installing concrete flooring happens to be one of Painter’s strengths. While concrete is our material of choice, our specialists will happily help you find methods for protecting wood floors.

The 5 perks of covering wood floors with epoxy

As we stated, the benefits of epoxy floors boil down to style, longevity and flexibility. But let’s get a little more specific — how can wooden floors benefit from being covered by epoxy? Here are five ways.

1. Epoxy saves wood floors

If you’ve got beautiful wooden floors in your office or your home’s patio, epoxy can protect them from getting chipped, cracked or split by heavy foot traffic or the scraping feet of patio chairs and tables.

2. Epoxy saves wood from toxins and staining

Wood floors are a great way to add a little class to a business place, like a showroom or restaurant. However, business areas require professional cleaning, and hardcore solvents and bleaches can ruin the wood. Epoxy, however, is chemically resistant, so you can keep your floors spotlessly clean without thinking about bleaching.

3. Epoxy coating makes wood floors food safe

You may have wooden kitchen floors if your home’s got an open floor plan, and if you run a restaurant, you’ve seen your fair share of dropped plates and spilled drinks. Residential epoxy coats are stainproof and waterproof, and can protect expensive wood floors from food and drink spills.

4. Epoxy can protect your stylish wood — or improve it

If you want to keep your space’s beautiful wood floors, then let us put a discreet, clear epoxy coating. However, if you want a new look totally, then we could offer a flaked, coloured or shiny epoxy floor coating; we have an awesome range of artistic epoxy finishes for you to choose from.

5. Epoxy is easy to keep

With its chemically impenetrable, waterproof and perfectly smooth surface, epoxy is a dream to clean. With a quick sweep and mop, you’ll be free of all dust and dirt without ever having to worry about spots, mould or mildew.

The risks of covering wood floors with epoxy

The risks of coating your wooden floors in epoxy don’t come from the material itself, but from bad fitting. Laying epoxy is a delicate and exact process, and the installer must change the process to account for the features of the room, including its temperature, moisture levels and airflow.

Failure to account for these any other factors will result in a weakened epoxy covering and possibly in long-term damage to the wooden floors beneath.

One of the risks of putting epoxy over wood is the air and wetness trapped beneath, between and within the wooden planks. If the wood isn’t properly prepared, the releasing air will cause lines, bubbles and blisters on the surface of the epoxy. The moisture can do the same and may even change the makeup of the epoxy resin.

The basics of putting an epoxy floor finish over wood

When we say ‘the basics’, we mean it — this is not a how-to book. Laying resin is an adaptable process because every spot is unique. That’s why it takes a professional. To give you an idea of what the process involves, let’s look at some of the basic steps involved.

Preparing the wood

We must ensure that your wooden floors are exactly flat and level, meaning there are no high points, low points or slopes. Preparation could involve a number of steps, such as sanding back parts of the floor or cutting down or removing extruding nails and screws.

Once all of that’s done, the floor needs to be fully cleaned to remove any dust and dirt. The cleaning must be done carefully so as not to add extra moisture or air to the wood.

Sealing the wooden floor

Now, the wood must be properly sealed with epoxy crack filler. We’ll have to fill every nail and screw hole and every crack, scrape and chip, as well as the gaps between the floors. This process is extremely time consuming as it is, but it can be further difficult if you want a clear epoxy coat, as we’ll have to ensure the wood is sealed yet attractive.

Priming the wood

Concrete can be prepared for an epoxy floor by grinding it, but wood needs a different process — it needs to be covered with primer. We’ll use our knowledge to decide what kind of intro is best.

If your floors are made of flexible plywood, we’ll have to apply flexible epoxy filler, which can gently bend with the wood without cracking it.

We’ll then apply a second coat of prep, the chemical makeup of which will depend on your spot. In tightly sealed areas or spots with high cleanliness standards, we’ll apply waterborne epoxy primer. Water-based primers are low in volatile organic compounds, so don’t bring harmful chemicals into the air during installation. The downside of water-based starters is that they’re also a little weaker than their solvent-based peers. For stronger defence, we could use a solvent-based primer that’s far harder but needs more time for curing.

Finally, putting the epoxy wood coating

Mixing epoxy resin needs extreme accuracy. While you can buy off-the-shelf epoxy that comes with full mixing directions, the industrial-grade epoxy we use requires a more deft hand, especially if it needs additives and colours mixed in to get the unique finish you’re after.

Once the resin is made, we can get to the real fitting. Looking at a picture of the process, you might think putting cement looks no more difficult than painting a wall. The similarities are purely cosmetic — epoxy is far more dangerous. Not only can wet epoxy let off unpleasant fumes, but the chemical reaction taking place can burn you if you’re not careful.

Now that the epoxy’s set, you could decide to add an additional finish, such as an anti-slip protective urethane top coat. That’s a whole process in itself.
