Can Epoxy Be Installed Over Tile Floors?

Epoxy flooring is gaining popularity among businesses and homeowners. Frequently asked questions are about whether epoxy coating may be placed directly on top of tiles, another common flooring option. You might be curious whether epoxy can be applied straight over your current tiles.‍ Tile removal can be a time-consuming, challenging, and costly task. A possibility is covering tiles with epoxy. Before using a long-lasting, high-performance epoxy coating, there are a few things to consider. This article will examine the viability of applying epoxy over tile floors while examining the benefits, factors to consider, and potential difficulties that may arise. By the end, you’ll know whether epoxy is a good choice for remodelling your tile flooring.

Tips Before Applying Epoxy On Top Of Tiles

Condition Of The Tile

Tile that is slippery, dirty, and incompatible with epoxy is a regular source of trouble. There is a possibility that water, bacteria, and other contaminants are present in the dirt substrate on which the tile is laid. The tile’s ability to adhere to the floor may be affected. Tiles will become loose in areas where the adhesiveness of the tiles to the original substrate has decreased. The appearance of loose tiles can identify these areas. Consequently, the epoxy will have a reduced capacity to adhere to the floor tiles. If there are more than a few cracked tiles in a single section, the floor should be completely redone.

Condition Of The Grout Lines

Since grout is porous, it readily takes in dirt, grime, bacteria, and any other debris that may be present. In addition, the grout lines must be corrected to ensure the epoxy successfully adheres to the floor. As part of the initial inspection of the floor tiling, you should pay particular attention to the condition of the grout. If there are multiple areas where the grout is worn out or damaged, the contractors may need to remove the tiles and dig up the grout lines to fix the problem.

Type Of Tile

There are many kinds of tiles. Hence the term “tile” is quite vague. Some examples of tiles are ceramic, quarry, vinyl composition tile (VCT), and linoleum. The type of tile that was initially laid is also a factor in determining whether or not the tile needs to be entirely removed before epoxy can be applied.

• Bathrooms, locker rooms, foyers, and some workplaces frequently have ceramic tile flooring. Glazed ceramic tile is notoriously dangerous due to its slick surface. This means that shot blasting or diamond polishing the tile surface is required before epoxy installation. The tile and grout may be severely damaged during the surface preparation procedure, necessitating much work. Removing all ceramic tiles is often recommended as the first step in the restoration process by many professionals, particularly in cases where the tiling is older and shows obvious signs of deterioration.
• Older commercial kitchens often have quarry tile floors, and instead of tearing them up completely, they can benefit from mechanical surface prep. Because the surface of quarry tiles is unglazed and more “open,” it can be appropriately prepared for effective epoxy adhesion by shot blasting and grinding.
• Linoleum and vinyl composition tiles, sometimes known as VCT for short, are two types of flooring that feature synthetic tiles attached directly to the substrate. Linoleum is produced using natural linseed oil, while VCT uses synthetic chemicals. Linoleum can be found on floors. This is the most significant difference between the two kinds of flooring available. In each of these two scenarios, the tile floor’s age is considered when assessing whether or not it is required to remove the tile or to prepare the floor for the application of epoxy mechanically.
  • Regarding vinyl composition tile (VCT) and linoleum floors placed more than 20 years ago, the solvent-based mastic adhesives used to attach them to the substrate are frequently strongly attached. Grinding the VCT or linoleum and applying the epoxy is frequently the most efficient cost and labour-intensity method.
  • For two reasons, If the VCT or linoleum was very recently installed, it is possible that it would be more beneficial to remove the tile completely before applying the epoxy.

1. Water-based adhesives are the norm nowadays, as they are more user-friendly than their solvent-based predecessors.

2. There may be detectable levels of plasticiser and oil in even the most modern VCT and linoleum. Because of this, the epoxy’s ability to stick to the tile may be compromised.

Application Of Epoxy Floor Over Tiles

Examine The Tiles For Damage

Floors take a beating from foot traffic every day, so it’s important to inspect the tiles’ condition before applying the epoxy. Before continuing the application process, fix any water damage due to holes, cracks, or leaks.

In very humid climates, moisture is a formidable foe. Because of the trapped moisture, the tiles will eventually crack and rise. This will look better on your shiny epoxy flooring.

Old or weathered tiles should be replaced rather than repaired. Always check with a professional to see if your plan to install an epoxy floor over tiles will work.

Sand And Clean The Tiles

Clean the floor tiles thoroughly by removing all of the grease and oil. This is particularly relevant to the tiles in the kitchen and bathroom, but it also applies to the garage tiles. The coating will not spread evenly if epoxy is placed on an oily floor. Sanding the tile down will remove the finish applied to it. A wide variety of chemicals are utilised to improve tiles’ beauty and longevity. Some of them have a bright appearance, which makes it more difficult to attach them to the epoxy.

Level The Surface

Once you’ve determined that the tiles are in good enough shape for the epoxy to adhere, the following step is to get the tiles flat. Grout is used to connect tiles. Unfortunately, these tile grouts make it difficult to prepare a level, smooth surface on which to apply the epoxy. Nobody likes it when the edges of their new epoxy flooring stick out, or the grout lines show. Epoxy-based filler coat should be used to seal the grouts in such circumstances. Epoxy will accentuate surface imperfections such as cracks and unevenness. Although a self-levelling compound can be applied to the tile floor, mechanically grinding the tiles is the most effective method. This will get the floor level and remove the tiles’ top layer and prepare them for the epoxy coating. Grinding can reveal any broken or loose tiles on the floor.

Floor Primer Should Be Applied

Priming could take many hours, depending on the size of the floor that needs to be worked on. However, carrying out these steps before applying an epoxy coating helps to extend the floor’s useful life. In addition, it keeps the epoxy finish from cracking or flaking over time. Because the primer can permeate the base, the epoxy can coat the floor more easily. A low-viscosity epoxy primer is recommended when selecting a primer since it prevents moisture from entering the surface underneath.

Can Shower Floor Tiles Be Epoxied Over?

If you need a floor that won’t get damaged by moisture, epoxy is a fantastic choice. It thrives in wet environments like bathrooms. However, as it is also non-porous, slipperiness becomes a major issue when wet.

You may modify an epoxy floor to suit your requirements. Adding anti-slip chemicals to surfaces is one way to make them safer. It’s important to exercise caution while using additives like fine silica sand and aluminium oxide, which are available for purchase. The best solution for the bathroom is an epoxy floor finish with polymer grit mixed in.    

The tiles on your shower floor may not be able to handle an epoxy finish. Once again, the answer is the condition and material of your flooring. Wetness under the tiles is possible in bathrooms with showers since the floor is always damp. If you’re wondering whether or not an epoxy floor is the right choice for your space, it’s advisable to have a professional flooring inspector take a look first. 

Epoxies Adhere To Tiles, Right?

Adhesion is of utmost importance when working over a tiled floor, when applying epoxy to the tile and when installing the tile directly onto the concrete. The glazing process leaves some floor tiles with a glossy sheen, making them difficult to adhere to. Glazed tiles require sanding to reduce gloss before epoxy can adhere properly. Micro-etching with acid-based etchers is an option, but it’s hit-or-miss. Because vitrified tiles are impermeable and uniformly hard, grinding alone may not create a secure joint. These often require the use of a primer designed specifically for the material.

For example, many terracotta tiles aren’t glazed, but a sealer can be applied to keep them from looking dusty or displaying a spill, creating the appearance of a glossy finish. Because sealers typically have hydrophobic qualities and might be problematic if approached like a normal coating, grinding may also be necessary if the tile has been sealed.

Inspect the grout lines just as thoroughly as the shine and sheen of the tile itself. The threat of contamination is the main worry. Grout, being porous, tends to absorb all types of filth and grease, which might interfere with the adhesive properties of epoxy. Removing the tiles and grout from a commercial kitchen or another area with a high oil pollution risk may be necessary.

As discussed, the bond quality between floor tile and concrete depends on the adhesion issue. Tiles that have become “dummies” over time are a potential flooring weak spot. If more than a few tiles are found loose during the examination or begin to shatter, fracture, or burst while grinding, it is likely best to remove them completely so the underlying concrete can be utilised. 

Is Tile Removal The Best Option? 

In many cases, the condition of a tiled floor will not allow for any other option than to remove what is there and return the floor to its original, clean and sound concrete state. Raising the floor tiles is, in most instances, relatively easy; it is the glue behind that can trip up contractors because removing and flattening is notoriously difficult and time-consuming. The damage done to the concrete while removing tiles is something else that can fall through the cracks, if you pardon the expression. Suppose you intend to refrain from making use of a floor leveller. In that case, you will typically need to make provisions for a significant amount of patching to repair divots and chips before installing the epoxy floor.

In general, when it comes to epoxy flooring over tiles, you should prioritise returning to concrete whenever it is feasible. However, the decision you make in the end will frequently depend on your preferences and how you feel about the additional expenses, time, and risks connected with either alternative.

Conclusion

Epoxy flooring is becoming increasingly popular among businesses and homeowners, but it is important to consider the viability of applying epoxy directly over tile floors. Tile removal can be time-consuming, challenging, and costly, so it is crucial to consider the conditions of the tile, grout lines, and type of tile. Tiles like ceramic, quarry, vinyl composition tile (VCT), and linoleum can affect the adhesiveness of the epoxy.

To prepare the floor for epoxy application, consider the type of tile, such as ceramic tile, quarry tile, or linoleum and vinyl composition tiles. Ceramic tiles are often removed before epoxy installation, while quarry tiles can be prepared for effective epoxy adhesion through shot blasting and grinding. Linoleum and vinyl composition tiles are two types of flooring that feature synthetic tiles attached directly to the substrate.

To apply epoxy, examine the tiles for damage, fix water damage, and replace old or weathered tiles. Old or weathered tiles should be replaced rather than repaired, and it is essential to consult a professional to ensure the epoxy will work on the affected area.

To clean the floor tiles, remove all grease and oil, especially in kitchens and bathrooms, as the coating will not spread evenly if it is placed on an oily floor. By following these steps, you can ensure the successful application of epoxy over tile floors and achieve a long-lasting, high-performance flooring solution.
