A commercial kitchen floor and an office lobby may both use tiles, but the conditions beneath them are very different.
One deals with hot water, grease and frequent cleaning. The other mainly handles foot traffic. Using the same tile adhesive for both simply because they are commercial spaces can lead to over-specification in one area and failure in the other.
Industrial and commercial tile adhesive selection should begin with the conditions the floor or wall will face. When chemicals, thermal shock, specialised substrates or moisture-sensitive stone enter the picture, a cement-based adhesive may no longer be the right choice.
That is where an epoxy tile adhesive becomes relevant.
What Makes Epoxy Adhesive Different?
An epoxy adhesive uses resin, hardener and filler components that react after mixing to form a dense, high-strength bond.
Cement-based adhesives cure through cement hydration and are suitable for a wide range of everyday tile installations. Epoxy adhesives are generally selected for more specialised conditions where chemical resistance, substrate compatibility or high mechanical strength is required.
This does not mean epoxy is automatically better for every project. It means it performs a different job.
When Should You Consider an Epoxy Tile Adhesive?
Four site conditions usually indicate that an epoxy system should be evaluated.
1. The area is exposed to chemicals
Food processing units, laboratories, pharmaceutical facilities and chemical plants may expose tiled surfaces to acids, alkalis, oils, cleaning agents and other substances.
Chemical resistance should never be assumed from the word “epoxy” alone. The exact chemical, its concentration, temperature and duration of exposure must be checked against the manufacturer’s chemical-resistance chart.
An adhesive may resist one chemical under continuous exposure but may not be recommended for another.
2. The installation involves a specialised substrate
Most cement-based adhesives are designed primarily for concrete, plaster, screeds and other cementitious surfaces.
Industrial and commercial projects may also require tiles or stone to be fixed over:
- Metal
- Wood or plywood
- Existing epoxy surfaces
- Rubber
- PVC
- Linoleum
- Drywall boards
These surfaces behave differently from concrete. Product compatibility and the load-bearing capacity of the substrate must be confirmed before installation.
3. The stone is sensitive to moisture
Some natural and engineered stones can curl, warp or change appearance when exposed to moisture from a conventional adhesive.
An epoxy adhesive that does not introduce water into the installation can help reduce this risk. This is particularly relevant for moisture-sensitive marble, agglomerated stone and certain light-coloured materials.
A sample installation is advisable when the stone’s behaviour is uncertain.
4. The area experiences demanding service conditions
Industrial floors may face equipment loads, cleaning cycles and temperature changes. Commercial kitchens and food plants may also experience hot-water washdowns, grease and frequent chemical cleaning.
The complete tile system should be evaluated for these conditions. This includes the adhesive, grout, substrate, movement joints and tile itself.
Epoxy Adhesive or Cement-Based Adhesive?
The choice depends on the application rather than the project label.
| Project condition | Cement-based adhesive | Epoxy adhesive |
|---|---|---|
| Standard internal tile installation | Usually suitable | Often unnecessary |
| Concrete or cement-plaster substrate | Commonly suitable | Can be used if the application requires it |
| Regular pedestrian traffic | Often suitable with the correct grade | May not be required |
| Frequent chemical exposure | Limited, depending on the product | Often the more suitable option after checking chemical compatibility |
| Metal or existing epoxy substrate | Usually needs a specialised solution | Can be suitable if approved by the manufacturer |
| Moisture-sensitive stone | May introduce unwanted moisture | Can help reduce curling and staining risks |
| Industrial processing area | Depends on operating conditions | Suitable where chemical and performance requirements justify it |
An airport or shopping mall does not automatically need an epoxy adhesive simply because it has heavy foot traffic. A pharmaceutical unit or food-processing area may need one because its cleaning chemicals and operating conditions create a different level of exposure.
What to Check Before Selecting an Industrial Epoxy Adhesive
Chemical compatibility
List the chemicals used or produced in the area. Record their concentrations, temperatures and whether exposure will be occasional or continuous.
The selected adhesive should be checked against this exact exposure profile.
Tile and stone type
Confirm whether the material is ceramic, vitrified, glass mosaic, natural stone, engineered stone or metal tile.
Some stones have size limits or special installation requirements. Colour-sensitive materials may also need a white adhesive.
Substrate
The substrate should be structurally sound, stable and compatible with the adhesive. For boards and flexible surfaces, check the manufacturer’s load-bearing and preparation requirements.
Temperature conditions
Consider the temperature during installation as well as the temperature the finished surface will experience.
Thermal shock can occur when a surface moves quickly between hot and cold conditions. The entire tile assembly must be designed for that change.
Working time
Epoxy adhesives begin reacting as soon as their components are mixed. Applicators need to work within the stated pot life and should not mix more material than they can place in that time.

The exact tile, substrate and exposure conditions should always be checked against the latest technical data sheet.
Installation Details That Matter
Epoxy adhesives perform differently from cement-based products. Applicators should be familiar with the mixing and placement process before work begins.
Prepare a dry, stable surface
The substrate must be structurally sound, fully cured and free from dirt, oil, grease, loose paint, laitance, sealers and curing compounds.
Uneven surfaces should be corrected before adhesive application.
Mix the complete system correctly
LATAPOXY® 300 is supplied as a factory-proportioned three-component unit. The resin, hardener and filler must be mixed according to the product instructions.
Do not add water or solvents.
Work within the pot life
The stated pot life is approximately 45 minutes at 21°C. Actual working time can change with site temperature and conditions.
Warmer conditions generally reduce the available time, so the mixed material should be used promptly.
Aim for proper contact
Use the recommended notched trowel and application method. The adhesive must make adequate contact with both the substrate and the back of the tile.
Coverage requirements should be based on the application and project specification.
Clean while the adhesive is fresh
Cured epoxy is difficult to remove. Tools and affected tile surfaces should be cleaned at the stage and with the method recommended in the product instructions.
Mistakes That Can Compromise the Installation
Treating every chemical as the same
Resistance varies between chemicals and exposure conditions. Always consult the chemical-resistance chart.
Dividing the kit by estimation
Incorrect proportions can result in incomplete curing or inconsistent performance. Use the complete factory-proportioned unit unless the manufacturer provides an approved alternative method.
Adding water or solvent
Extra liquids can interfere with the formulation. Mix only the supplied components.
Applying over a damp or uncured substrate
LATAPOXY® 300 should be applied over a dry, properly cured and stable surface.
Ignoring the grout
Chemical-resistant adhesive beneath the tile does not protect a joint filled with an unsuitable grout. Industrial installations may require a compatible industrial epoxy grout based on their exposure conditions.
Choose According to Exposure, Not Assumption
Epoxy tile adhesive is not required for every commercial floor. It becomes valuable when the installation must handle specific chemicals, specialised substrates, moisture-sensitive stone or demanding operating conditions.
LATAPOXY® 300 offers high bond strength, chemical resistance and compatibility with a wide range of approved substrates. Its three-component formulation makes it suitable for specialised industrial and commercial tile installations where an ordinary cement-based adhesive may not meet the project requirements.
The best specification begins with a clear assessment of the environment. Identify what the surface will face, check the product data and chemical-resistance chart, and design the adhesive and grout as part of one complete installation system.
Frequently Asked Questions
Is epoxy adhesive necessary for every industrial floor?
No. The need for epoxy depends on chemical exposure, substrate type, temperature conditions, tile material and project requirements. Some industrial areas may be suitable for a high-performance cement-based system.
Can LATAPOXY® 300 be used on metal?
LATAPOXY® 300 can bond to approved metal substrates. The metal must be stable and prepared according to the product and project requirements.
Is epoxy tile adhesive waterproof?
A cured epoxy adhesive offers strong resistance to water, but it should not automatically be treated as a replacement for a dedicated waterproofing system. Waterproofing requirements must be evaluated separately.
Can LATAPOXY® 300 be used for engineered stone?
It can be used for approved engineered-stone and agglomerate installations. MYK LATICRETE states specific size and application limits, so the current technical guidance should be checked before installation.
How long can LATAPOXY® 300 be used after mixing?
Its stated pot life is approximately 45 minutes at 21°C. Actual working time may vary with temperature and site conditions.
Does chemical-resistant adhesive also require chemical-resistant grout?
Yes, where the tiled surface will be exposed to chemicals. The grout joints are part of the same installation and should be specified for the expected chemical and operating conditions.
