The good news is that full chemical epoxy curing time is about 7-days – this means it takes a week for the final coating to harden completely. Drying times are different. For a coating to dry, this mostly happens overnight.
However, not all epoxy coatings are created equal. You could be using water-based or solvent-borne epoxy (the stuff that smells quite strong), and you could have a higher or lower percentage of solids.
The technical data sheets determine dry times, reapplication times, and other basic rules and guidelines. Let us look at how long it takes for epoxy floors to dry.
Epoxy curing time is typically 7-days. Of course, there are variations, but if you want a rule of thumb, 1-week is your answer. While it takes 7-days for the epoxy to cure, your floor may be dry enough to walk on after 12-hours or so and ready for light use after 24-hours.
Be cautious, however, as these timeframes do not apply to all situations. The colder and less humid an environment, the longer the process.
For example, at a temperature of 20⁰C and 60% humidity, you may be able to return furniture and other items onto your floor in 2 to 3-days. If you are returning furniture or racking onto your newly finished floor before the 7-day mark, understand that, like a new concrete slab, the floor will feel hard and indestructible, but there is more going on underneath. Always be sure to cover furniture feet to minimise damage. Avoid dragging furniture, too. Lift and place instead.
Finally, if the work occurs outdoors, the weather forecast and conditions for the time surrounding your planned work need to be calculated. Your floors require consecutive days of fine weather to dry. If rain is predicted or other conditions are adverse, be patient. Your applicator will provide guidance.
FAQs About Curing Time For Epoxy Flooring
How The Product Type Affects Epoxy Curing Time?
The product itself plays a pivotal role in the epoxy dry time. Some believe if they maximise ventilation by opening all the windows, their new flooring will dry faster – like paint. In certain instances, this is true.
In most, it is not. Instead, you may be better off creating a humid environment, as some epoxy is ‘moisture-cured’ – meaning they require moisture and heat to dry and harden.
Therefore, in hotter environments, we can apply coatings during the times of day in which the concrete is cooling – around mid-afternoon. Coating epoxy to concrete that is warming can cause a host of issues.
How Can I Speed Up The Epoxy Curing Process?
Depending on the epoxy product you are using, you can speed up the epoxy drying time by creating a humid and warm environment, or a free-flowing ventilated environment, as mentioned with some products.
There are also epoxy products that dry ridiculously fast. They are, however, expensive and sometimes require significantly more labour to control the application process accurately.
These fast-drying epoxies are specifically engineered for areas that need to be open for traffic fast, cold areas like fridges; commercial kitchens; and businesses that cannot close without suffering financial loss.
A speedy return to service sounds ideal! However, you can end up with serious problems later. For instance, if you had a sub-standard concrete slab. On the day of the concrete pour, it was hot and, to give themselves more working time with the concrete, the contractor added more water than is suggested & appropriate.
This can compromise the integrity and overall cured hardness of the concrete and raise the ‘fines’ of the concrete to the top. In the worst case, a fast-drying epoxy-based product just cannot ‘grip’ onto the surface properly because it needs slower processing times to work effectively.
Most epoxy is made from Part A (resin) and Part B (hardener). These two components need to cross-link with each other and the concrete to fully bond. When the concrete quality has been compromised, combined with the use of a fast-drying product, the result will not be good. Within months, the coating can tear off and need to be re-done. It is worthwhile asking yourself: Do I need to have the work completed so quickly? Another question I raise is: Who benefits the most from faster-finished work?
It certainly sounds appealing to know you can have your garage completed in a day, but I like a quote that states: ‘One minute of patience, ten years of peace’ – Greek Proverb.
Chances are, waiting the extra time is worthwhile – and not just for now. Too often, the faster run jobs produce instant results, and the applicator is paid, but then the work fails, and the applicator is gone.
Do your homework and view products with a critical eye.
Everybody has the ‘best’ products, but they need to be ‘fit for purpose’, mostly from a conversation about YOUR project. A technical datasheet will reveal more information, but you almost need a degree or advice from an expert to ascertain what it all means to you and your project requirements.
How Long Do I Have To Wait To Epoxy New Concrete?
The typical concrete slab requires 28-days before coating – as a bare minimum. Just round it up to a month! Even then, the moisture will need to be assessed and physically tested to ensure the concrete is ready for coating. This is a general rule, so keep in mind the variables at play:
- The thickness of the concrete
- Curing conditions
- Components in the concrete
- What the concrete will be coated with
Moisture is a key culprit we want out of the slab before an epoxy coating is laid. Slabs may have excess moisture for several reasons, and a moisture vapour treatment or barrier (such as a damp-proof membrane or DPM) can be applied to counteract it.
This prevents moisture from rising within the slab and can withstand vast water pressure. If your concrete slab has a coating that completely seals the surface, the water pressure (also called hydrostatic pressure) can build up and rip through epoxy. Investing in moisture treatment can be crucial.
What Is The Curing Time For Epoxy Flooring?
If you’re thinking about installing epoxy flooring in your home or commercial building, you’re likely wondering how long the entire process takes. This can be especially pressing if you’re planning on installing it in a high-use area such as a garage.
Usually, the installation process can be finished within a day or two. This will typically depend on how much preparation the old floor will need before the new floor can be placed. Once the flooring is installed, all you need to do is wait. But how long will it take to cure fully?
How Long Does Epoxy Flooring Take To Cure?
Cure time for epoxy flooring will vary from job to job. Several factors will play into the exact time it will take to dry, including the type of epoxy application you’ve selected. The solids content of the products being used will also affect return-to-use time.
Using 100% solids epoxy, your floor will be cured and walkable in about 12 – 18 hours.
You can return to full heavy traffic after about 36 – 72 hours. Most epoxies reach full chemical cure within seven days of application. When using poly aspartic, the cure times increase, especially with 100% solids products. Most polyaspartics are walkable after 6 hours and can be returned to normal service after 24 hours.
When Can I Walk On My New Epoxy Floor?
You don’t have to wait until your epoxy floor is fully cured to walk on it.
Most experts agree that epoxy is safe to walk on after about 25 hours (that extra hour counts), and polyaspartic is ready after about 6 hours. But it’s still a good idea to wait the full 48 – 72 hours before exposing your new floor to any heavy traffic or heavy equipment.
How Are You Going To Prepare The Floor For Permanent Adhesion Of The Final Epoxy Floor Coating?
There are several different ways you can prepare your surface for a coating to be laid on it, but one way that is never an option is no surface preparation at all! Not every form of surface preparation is appropriate in all situations.
Sometimes even the highest quality option is too aggressive for your situation, and often the gentlest and cheapest is not aggressive enough to ensure your finished product does not de-laminate. Of course, if you want polished concrete, this is the most vital question of all! Some options for floor preparation include the following, from lightest to most industrial:
- Concrete Sanding
- Concrete Grinding
- Shot-Blasting
Will Winter Temperatures Change The Curing Time?
Weather conditions can affect the viscosity, adhesion, and curing time. So, in short, yes. Winter temperatures can play a role in how long the installation takes.
Typically, a good range for applying epoxy is from 55 – 90 degrees Fahrenheit, though certain epoxy and polyaspartics are manufactured specifically for lower temperatures, even below freezing. But the floor’s temperature is more important than the temperature of the air.
Before an installation can commence, it’s important to check the slab temperature with an infrared thermometer. If you have a heated garage, it can take days for the slab to get up to the proper temperature, so plan.
Also, remember that you need to maintain that heat throughout the drying process, or your floor might not cure properly. Humidity can also play a role in curing time. It’s best to hold off on installation if humidity levels are above 85%.
This can cast a thin layer of moisture over the epoxy and affect its bond to the surface. Again, this is dependent on the type of product you use. Some resinous flooring will cure faster and stronger with higher humidity, while others require low humidity.
The bottom line: ensure that whoever is installing your flooring has taken all of these elements into consideration so they can choose the best product for your floor.
Ready To Install Your Epoxy Floor?
There are countless reasons why you should choose epoxy flooring. Epoxy flooring is a winning option for your home or business, from its superior abrasion resistance to its sleek finish.
Your epoxy floor will even hold up against high-traffic wear and tear.
Maintenance Tips
Curing Time
A period of seven days should normally be allowed after applying the finish before any wet cleaning process is carried out.
During this curing period, which will be dependent on site conditions and ambient temperatures, floors should be suction cleaned or lightly swept with a soft broom. For Curing times, please refer to the relevant product datasheet.
Cleaning
This can embrace a whole range of activities, from damp mopping of small, lightly soiled to heavy-duty machine scrubbing to remove ground-in dirt or compacted oil and grease.
To be effective, the equipment used should be appropriate for the size and nature of the tasks to be undertaken. When selecting the equipment, consideration must be given to the type of surface to be cleaned, especially those with a slip-resistant / textured finish.
- Mopping equipment (various types) for small, relatively clean areas.
- Rotary scrubbing machines for deep cleaning in confined or restricted access areas (used in conjunction with mopping equipment).
- Wet suction machines may be used with mopping equipment and rotary machines to pick up cleaning solutions.
- Combined scrubbers/driers for use in larger open areas where, depending on the machine’s size and capacity, up to 3000m2 per hour can be cleaned.
Do not use abrasive cleansers. Try using a soft bristle brush instead, as hard bristles act like sandpaper. Do not use acid-based cleaners. They will damage your flooring and must not be used.
Do not use strong alkali based cleansers. They can be very dangerous and must be diluted as per the product’s instructions and never used in their concentrated form.
While some solvent “activated” cleansers are suitable, avoiding using any solvent cleaners in the main is better. Scraping the surface of the epoxy flooring should be avoided, but it is okay to lightly use a scourer sponge together with plastic scrapers or squeegees.
Ensure they have rounded corners as they are less likely to scratch the surface of the floor.
After Installation Care
First and foremost, your new flooring system must be permitted to cure before being walked on fully. Lightfoot traffic – 24 hours if an average temperature is 20°c, but 48 hours if around 8°c.
Full mechanical and chemical loading (i.e., garages and commercial zones) will require seven days with the temperature averaging 20°c and 14 days with an 8°c average temperature (but always take care of heavy equipment across the new floor).
Removing dust and sand is the most critical part of maintaining your epoxy floor, as dust and sand build-up may become abrasive and scour your floors over time.
Routine Maintenance
The extent and frequency of all routine maintenance will depend on many factors – type and level of activity within the area; the required level of hygiene or desired standard; the existing floor system to be cleaned, its overall size and texture; the soiling held on the surface.
Equipment And Sweeping
The equipment used for the care and maintenance of your TLC Epoxy Coatings Floor should be relevant to the area involved. They should incorporate, wherever possible, mechanically or electrically driven equipment/machines.
This is an integral part of all cleaning procedures. Surface dirt and loose debris are unsightly and can be very abrasive. Therefore, they must be removed effectively and regularly using:
Brooms, brushes or suction cleaners for small or difficult areas only.
Dust control mops for light dry dust and debris and only smooth finishes.
There are mechanical sweepers for larger areas and possible’ ride on’ sweepers for very large floor areas / open spaces.
Polishing Epoxy Flooring
Now that the washing process is completed, you can polish your floor. You can use approved clear polymer glaze coats or wax polishes to protect the upper surface from minor scratches and abrasions for this task.
You will find that wax modified cleansers are most likely to be the ones that will provide improved scratch resistance.
Metallic style polishes will give immediate protection, and it is recommended that you apply at least three coats following the washing procedure. You will find that three coats can comfortably be applied on the same day.
The polishing application should be repeated every three months.
The fact of the matter is that plenty of businesses will be keen to sell you a flooring system that will fail; as long as they get paid, they don’t care what else happens.
They will make you sign on the dotted line, absolving themselves of any liabilities on their part and then they disappear, leaving you with the cost of removing their terrible artistry and reinstalling the floor you wanted. It’s a nightmare. We have heard this story too many times to stay quiet about it.
How much does it cost to epoxy garage floor?
