how to epoxy over granite countertops?

You’ve probably heard of epoxy-based countertop resurfacing, but what if you have granite? Well, that’s a good question!

The short answer is: yes, you can use epoxy over a granite countertop. The long answer is more complicated—it depends on the type of stone you have and whether or not it has been polished.

If either of those things is true then YES! I’d recommend doing your research before committing to anything though.

Can you put epoxy on top of granite?

Yes, you can put epoxy on top of granite. Epoxy is a two-part resin that is mixed together to create a solid layer, which can be applied to almost any surface.

Epoxy has many benefits: it’s durable and easy to clean, and it gives your countertops an added shine. However, be sure to consider if this is the right choice for you before you begin applying epoxy over your granite countertops.

If you have kids or pets, then epoxy may not be the best option for your kitchen or bathroom because its hard surface makes it difficult to clean up messes like spilled water or food crumbs (pet fur).

Does epoxy over granite last?

Epoxy is a great choice for countertops. It’s durable and easy to clean, so you can use it in any room of your house.

If you have granite countertops, epoxy is a good choice because it bonds well with granite that has been treated with a sealant or polish.

Epoxy also provides protection against heat and water damage, so your new countertops will stay looking like new for many years.

What kind of epoxy do you use on granite countertops?

The most important thing to know about epoxies is that they come in two types, UV-cured and heat-cured. UV-cured epoxies are best suited for smaller projects like jewelry or crafts but are not recommended for countertops because they are yellow over time.

Heat-cured epoxy works best for large projects such as countertops because it won’t yellow as it ages and can be sanded down if necessary.

You also want to make sure you’re getting a quality brand of epoxy from a reputable company like Rustoleum or 3M which have been around for decades (and decades!). You don’t want some cheap knockoff that will crack after one use!

If you’re working with granite countertops then use an acrylic resin-based epoxy such as this one from Benjamin Moore.

It’s neutral in color so it won’t discolor the granite or stain your hands while applying it – plus there are no VOCs released into the air during the curing process so your lungs will thank us later!

How do you prepare granite for epoxy?

  • Clean the surface with a degreaser.
  • Use a wet rag to wipe the surface dry.
  • Use the vacuum to remove any dust that remains on the surface.
  • Heat up the area with a hair dryer, which will help make sure there’s good contact between epoxy and granite, as well as reduce bubbles in your finished product.
  • Scrape off any remaining dust with a razor blade (be careful).
  • Use a foam brush to apply epoxy, starting at one corner of your countertop and working your way down toward its center until all surfaces are covered by wet epoxy

Why You Should Not Do epoxy resin countertops?

You should not use epoxy resin countertops for the following reasons:

  • They were expensive. Epoxy resin countertops are more expensive than laminate or solid surface materials, which is why many homeowners choose to go with one of these alternatives over epoxy resin.
  • They’re hard to clean. The smooth and glossy finish on an epoxy resin countertop makes it difficult to get stains out of, so if you have kids or pets who make messes regularly, then this might not be the material for you!
  • They’re very slippery. Epoxies aren’t recommended for heavy-traffic areas because they’re super slippery (even when dry), which can cause accidents in your home like falls or burns from hot pots dropping onto unsuspecting fingers resting on your new counters’ surfaces while cooking dinner late at night after work…which leads me back around the full circle into my original point about ease of maintenance being a major factor here too!

How do I prep my countertop for epoxy?

Before you begin, make sure to clean your countertop thoroughly. Do not use any soap or soapy water; just wipe it down with a damp cloth and dry well.

Next, sand the surface. You want to use 120 grit sandpaper for this step; the finer your sandpaper is, the smoother your finish will be!

After that, apply a primer coat to seal in any remaining dust from sanding. This will also help prevent bubbling in the topcoat later on.

Finally: Apply two coats of epoxy overtop of all four sides of each piece of granite (or whatever type of stone you’re using).

Let dry for about five hours between coats—this allows for good adhesion between layers and prevents peeling when cured!

How much does it cost to epoxy coat a countertop?

The cost of epoxy coating a countertop can range anywhere from $0 to $3,000, depending on the size of your countertop and the quality of the epoxy.

The average cost is about $200 per square foot for an average-quality product.

If you have a small kitchen or bathroom with only one countertop area, then this is probably not the most expensive way to go.

It can get pretty pricey if you have a large kitchen or bathroom with multiple counters that need to be coated in order to achieve uniformity between them all.

Which epoxy is best for countertops?

Epoxy resin is a two-part system; when mixed together, it produces a hard and durable finish. It’s also a good choice for countertops because it can be polished to produce an extremely high gloss.
