Epoxy is one of the most useful materials you can use to protect, fix, and make over your surfaces. The resins in epoxy react with each other as they cure, creating a tough, durable surface that is resistant to heat and moisture.
Epoxy flooring can be used for a variety of industrial uses, including commercial garages and automobile repair facilities, but it also makes an attractive covering for concrete floors in the home.
Why choose epoxy? Epoxy is a strong material that provides durability, safety, and beauty. It is resistant to staining, chemicals, and abrasion.
This makes it ideal for coating garage floors where motor oil stains are inevitable or even inevitable as well as utility rooms or basements where exposure to water or chemicals may occur.
Epoxy adheres tightly to existing surfaces so there’s little danger of peeling or bubbling up over time like some other floor coverings do when exposed to moisture or heavy traffic loads.
Since it bonds so tightly with the underlying surface you can apply epoxy over virtually any flooring surface including ceramic tile, wood, and vinyl without worrying about damaging the existing surface if you ever need to remove it at some future point (if you move out of your house for instance).
Can you epoxy over epoxy?
You can apply epoxy over old epoxy, but you need to make sure that the old epoxy that is going to be coated is good and cured first.
If it’s not completely cured, the new layer of epoxy may not cure properly. You also need to consider how well the old epoxy will adhere to the substrate or pre-existing layer of epoxy. This can be affected by a variety of different factors, such as:
- The type of surface being coated (rough/textured vs smooth)
- The age and curing time frame of the existing layer
- The temperature at which it was applied (i.e., very hot vs very cold)

Will epoxy stick to cured epoxy?
Epoxy typically will not stick to cured epoxy. So, if you have a cured layer already covering your surface and would like to apply a new layer of different epoxy, you’ll need to provide the right surface for that epoxy.
You can sand the old cured layer of epoxy off, or if it’s only slightly tacky and your second layer is clear, you can leave the first on there. Then, use a primer before applying your second coat.
A common situation where this might arise is when someone tries to cover a tacky epoxy coating with another layer of epoxy in hopes that the new layer will cure the old one.
Epoxies are designed with specific curing agents for their use; however, sometimes these curing agents don’t work properly due to hardening too fast or not being compatible with the original resin used in production.
In any case, once an epoxy has been applied and begins curing/drying (which happens after mixing), it cannot be reactivated by adding more resin or solvent-based paint over top.
This means there’s no way around sanding down those stubborn spots on furniture legs before repainting them again!
Can you epoxy over old epoxy garage floor?
The short answer is yes! It’s possible to epoxy over an old epoxy garage floor. You just have to take a few important steps first:
- Remove all dirt, debris, and oil stains from the old coating.
- Decide whether you want to keep your old color or go with a new one. If you’re keeping your old color, lightly scuff the surface with a sanding screen and then vacuum any dust that is left behind. If you’re going for a new color, use a concrete cleaner/degreaser to strip the old coating off of the floor—you’ll need bare concrete for the new epoxy to be able to adhere properly.
- Apply an etching solution using a clean mop (the standard kit will include it). Follow directions on the etching solution’s container for exact application details since different manufacturers have different processes and drying times (ours will require anywhere from 10 minutes up to 24 hours depending on temperature). The etching should open up pores in your concrete so it can bond better with the new epoxy coating.
- Be sure not to step on or move anything across your garage floor during this time! Finally, rinse away all of the etching solutions and let them dry completely before moving on to step four.
Can u recoat epoxy?
It can be extremely frustrating if your first layer of epoxy was not what you expected. We’ve all been there, and it’s easy to make mistakes even when following the proper procedure. Sometimes you will see a foggy layer over your surface, or bubbles that weren’t properly removed before the first coat hardened.
You can recoat over epoxy at any time after the initial coat has cured. If it has been less than 24 hours since you applied the first layer but it feels dry/hard to touch and looks unclouded, it is still considered “wet” and should be removed before applying a new layer of resin.
To remove an uncured wet epoxy coating, sand it down using fine grit sandpaper (220-400) until no tackiness is felt when touched.
The next time you apply this area with epoxy resin, ensure that it is at a temperature above 70 degrees Fahrenheit for a minimum of 72 hours (3 days). This will allow for maximum curing efficiency and result in a flawless finish!
Can I put a second coat of epoxy resin?
Yes, you can apply a second coat of epoxy resin if the first coat has not cured.
You need to know when it is time to recoat your project with another layer of resin.
There are some things that need to be done in order for the second layer to adhere correctly.
It is also important to know how much time each step takes so that you will be able to complete your project before the second layer cures.
Does epoxy need to be clamped?
No! Epoxy does not need to be clamped, as epoxy is designed to withstand all of the forces that would normally require clamping.
Clamping is only necessary when you are trying to prevent something from moving or being forced out of shape. Epoxy is extremely strong and will hold things in place, even if it does not fill every possible void.
The only time you should clamp something using epoxy is when the cure temperature can get so high that it causes the two parts of your project to warp or bend away from each other during curing.
Should you sand between coats of epoxy?
The simple answer to the ‘can you epoxy over epoxy’ question is yes, but it will depend on how long it has been since the first coat was applied.
You need to sand between coats for two reasons: firstly so that any imperfections are removed and secondly to give a smooth surface for the next layer to stick to.
How do you resurface an epoxy floor?
- The first step is to clean your floors and remove any existing coatings. Epoxy can be removed using a variety of methods, but it will usually involve some combination of mechanical removal (scraping), chemical stripping, and grinding/sanding.
- Once the epoxy has been removed you are then ready to go about resurfacing the floor by sanding or grinding down the top layer of concrete. Epoxy adheres best to a rougher surface so this step is beneficial in ensuring proper adhesion. Another benefit to roughing up your floors is that you can remove any stains or contaminants that may still be present following the removal process.
- Finally, you will want to apply your new topcoat of epoxy over the newly resurfaced floor. Your coating choice will depend on what you plan on doing with your floor in terms of traffic and usage as well as how much protection you need from chemicals if they are being used in the space where your floor is located. For example, if you have a garage that sees heavy use from cars, tools, and other equipment then it’s likely going to need more protection than say an office setting where only light foot traffic occurs on a daily basis
How do you remove old epoxy from garage floor?
If you’re not happy with your old epoxy, you can try to remove it. Bear in mind that removing it can be a lot more labor intensive and expensive than simply painting over it. Here are some of the options you have for removing an old epoxy floor coating:
- Use a scraper or a drill with a scraper attachment. This is the most labor-intensive method, but also one of the cheapest. Make sure you wear safety glasses, gloves, and a dust mask when doing this. It may take several days to finish scraping off all the old coating.
- Use a chemical stripper or paint remover. You can buy chemical strippers at any hardware store. Just follow the directions on the bottle (wear gloves and a respirator). It will likely take several applications to get all of your floors clean.
- Use an electric sander or grinder to sand away from your existing coating then use an airless sprayer to apply new paint/epoxy over top once it’s clean. This is quick but dusty work so make sure you wear safety goggles and ear protection before starting! There’s no need for water blasting like there would be if only applying one coat of paint so this method saves time by skipping steps such as degreasing beforehand too!
Well, there you have it! In this article, we’ve learned about the enduring quality that epoxy provides and how easy and favorable it is to epoxy over epoxy.
