Epoxy resin is a type of synthetic resin that can be used to coat various surfaces. It’s also known as epoxy glue, epoxy putty, or liquid plastic and is often used for industrial purposes.
Epoxy resins are usually clear when they’re liquid but turn clear or opaque when hardened. You can use them in many ways: to repair broken objects; as the base coat for paint; or even as an adhesive for a project like this one!

How many coats of epoxy resin should I use?
First, you’ll want to determine the desired thickness of your epoxy finish. This will help you select the appropriate number of coats for your table top. If a thicker finish is desired, more coats will be needed; however, this can also result in increased curing time and cost if it’s used on the entire surface of a large table top.
If multiple layers are needed on large projects such as tables or countertops (as opposed to small pieces that can be easily sprayed with two or three coats), it may be advantageous to use an airless sprayer rather than hand application methods like brushing or rolling.
Do you have to sand epoxy between coats?
While it is important to sand epoxy between coats, this is not a requirement for every application. You will not need to sand between each coat unless you are applying an extremely thin layer of epoxy over a rough surface or in the repair of a deep scratch.
The reason why sanding is necessary between coats if your application requires it depends on your technique, the type of project at hand, and how well-prepared your surface was before applying the resin.
How thick should epoxy be on table top?
The thickness of your epoxy is also an important factor. There are a few different ways to go about determining the right thickness for your table top:
- Measure the size of the tabletop and make sure that you have enough epoxy to cover it completely. The most common recommendation is to use 1/16 inch, which means one coat will be roughly .0625 inches thick. For a thicker layer, try using 1/8 inch or even 1/4 inch for an extra durable finish! If you pour too much epoxy onto your table top, it may not cure correctly or evenly because there isn’t enough room in between layers for curing time (this is called “bridging”). On the other hand, if you don’t use enough epoxy on your tabletop and end up with gaps between coats, then they won’t bond together properly either so make sure not to skimp out on this step!
- When considering how many coats of clear coat sealant should go over top of multiple layers of colored paint? Most recommendations advise doing no more than two layers per color–and only one if possible–to avoid having things look too glossy or chalky as opposed to being smooth and shiny.”
How long should you wait between layers of resin?
Once you’ve finished the first layer of epoxy, allow it to cure for 24 hours before applying your second coat. Depending on the type of resin you’re using, this may be all that’s needed to get an ultra-strong bond. If you want even more strength in your table top, however, wait another 24 hours and apply a third coat (giving it 48 hours after each new application).
If it’s hot out when you’re applying epoxy—and especially if it’s humid—it will work better if you wait longer between applications than normal. This allows excess water vapor time to evaporate and prevents bubbles from forming as quickly.
How long should epoxy cure before sanding?
The curing time for epoxy depends on the resin and hardener mix. It’s important to follow the manufacturer’s instructions exactly, as they can vary based on the specific brand.
While it is tempting to rush through this process because sanding is fun, you don’t want the chemical reaction of your epoxy to be interrupted by pressure or heat before it has cured completely. Not doing so could damage your project and even lead to toxic exposure if you breathe in fumes from uncured epoxy.
Since most manufacturers recommend that once you have mixed up your materials, you should wait at least 24 hours before sanding them, it’s best not even try until then!
Can I apply epoxy over epoxy?
Yes, you can apply epoxy to epoxy.
- You need to make sure that both coats of epoxy are cured before proceeding with the second coat.
- If the surface is clean and free of dust, you should be good to go. You don’t want any residue from the first layer of epoxy getting on your second layer. This can cause problems with adhesion and bonding between layers because they won’t stick together well if there’s stuff on top of them!
- Make sure any wax or silicone is removed from your table before applying new coats of epoxy. These substances will prevent proper adhesion between layers and cause cracks in your finish later on down the road if left unattended for too long after application (hours).
How do you shine epoxy after sanding?
You can polish the epoxy with a buffer, but this is only necessary if you want to get it super smooth. You can also use automotive wax and polish on top of the coat of epoxy. A good alternative to these options is a cleaner wax or microfiber cloth—just be sure not to use any abrasive products or materials that will dull your final finish.
If you want an extra-smooth finish for your tabletop, wait until the clear coat has cured before sanding it with 220 grit sandpaper and then re-coating with another layer of epoxy. This will reduce friction between surfaces that typically create scratches in wood tables!
Can you apply a second coat of epoxy without sanding?
Yes, you can apply a second coat of epoxy without sanding. However, you need to wait long enough for the first coat of epoxy to cure before applying another. (If you’re using an epoxy product that doesn’t require sanding, this is much easier.)
In addition, make sure that any dust particles have been removed from your surface before applying another coat — otherwise, they could cause bubbles in the finished product.
To answer the question “how many coats of epoxy do I need for a table top”, we first have to consider what type of finish you’re looking for. If you just want a thick, glossy finish then one coat will suffice. However, if you want a more durable and scratch-resistant surface with an appearance closer to glass than varnish, then two or three coats might be needed.
You’ll also need to consider how thick the resin should be applied and how long it should dry between layers. This is highly dependent on temperature; in general, higher temperatures will cause epoxy resin to cure faster (which can be good if done correctly).
Finally: once cured, what’s next? Sanding! It’s best not to sand your table during application as this creates dust which may contaminate future layers but sanding immediately after each layer has been applied ensures that all parts are evened out before proceeding with another coat
