Concrete Countertop Sealer – DIY Guide

Let the sealer sit for five to ten minutes then wipe off the excess. To be honest, the countertop may look a little dark and strange at this point, but that’s okay. It will dry to its natural color with this sealer.
Concrete countertop sealer is necessary if you want concrete countertops. Remodeling a kitchen adds more value than remodeling any other room. This is because of the impression they make along with the components of a kitchen.
Solvent-based sealers penetrate concrete surfaces well. They give a rich and dark look. Water-based sealers with look matte after you finish and sit on the surface. Either works. Water-based is less toxic and solvent-based lasts longer.
When it comes to getting a shimmer that glimmers this is a great option. Oftentimes, both this topcoat and the Miracle Sealant are used. Because the Miracle Sealant has amazing protection and this one looks great.

What Is Concrete Countertop Sealer?

A concrete countertop sealer is a protective coating that you apply to concrete countertops to make them last longer and even look better. They come in many forms and don’t alter the color of your concrete as a stain does.

Now let this dry for eight hours or however long it happens to say on the package. You’ll notice that it doesn’t take as long to dry because it is thinner than the other sealer. But after you finish, there is a longer wait time.

Most of the time, concrete countertops do not need to be resealed, especially if they are well taken care of. If you have had them for over a decade, then there’s a good chance by the time that decade rolls around, you can add another coat.
If you want a super smooth countertop use very high count sandpaper. Then if you want a rougher texture more like stone, then use low-count sandpaper. Or, go with the naturally smooth texture of the unsanded sealer.

The Safecoat also offers protection but people usually buy it for the gloss that it adds. You will not find a better concrete countertop sealer that does more than protect your countertops but makes them look ten times nicer.

Never use products that aren’t made for natural stone or ones that are dangerous to eat around. These include polyurethane and other similar formulas. Never use polyurethane on your countertops.

Concrete needs to cure for about a month before you seal it. This seems like a long time but unless the conditions are perfect, you can’t seal it sooner than two weeks after you lay the concrete.

How To Use Concrete Countertop Sealer

After you have the sealer ready you can follow the directions on the bottle and slowly apply it to the countertop. Start by getting a separate container to use and carry it around with you. Then a soft bristle brush for applying. 
You can add as many coats of Safecoat as you want, just make sure that you lightly sand between each coat. As for the last coat, sanding is optional. If the countertop is the texture that you want it to be, then leave it. 

Step 1: Gather Sealer

You can use your own concoction of sealers or find one single sealer that you feel will do the job well. But if you are looking for recommendations, these two sealers work together to create a sight seal and a glossy bond.

Step 2: Apply Sealer

Do you know what else stains concrete though? Food, drinks, and anything else you may place on your countertops. A concrete countertop sealer will prevent these types of stains from ruining your countertop.

Step 3: Wipe Counter

Maintaining your concrete countertops isn’t at all difficult. The first step is to clean them every single day with an all-purpose cleaner. It can also be important to keep them dry which is helpful with any type of countertop.
Concrete sealer does darken as it ages, but this takes a long time. Your concrete won’t lose its natural color for quite a while and definitely not after the first application unless you buy a sealer with stain. 
Now it’s time to wait. You need to let the sealer dry for a day, or 24 hours. This is just for the first coat. You can apply as many coats as you want but it is difficult to tell how many you need, even after you apply them.

Step 4: Dry And Wait

This depends on the sealer. Epoxy and polyethylene can last up to ten years. Weaker sealers may only last one or two years. Be careful when you use strong sealers in the kitchen as it can be toxic to eat off of a countertop that you seal with chemicals. 
You can always wait for longer than it says on the package but you can’t wait for a shorter amount of time without problems. Climate does matter but just to be safe, wait the extra hours. Only good can come from it. 
While most people will have laminate, granite, or marble countertops, you can have concrete countertops too. This new trend is very attractive and the quality all comes down to how well the countertops are sealed. 

Step 5: Apply Second Sealer

You may be able to get by with one coat. But two coats are best. More than two and coats may stick together and peel off. Stick to two for best results. 
When it comes to sealing concrete countertops, all you really need to know is how to read. If you can read the instructions on the bottles of sealer then you can seal your concrete countertops. But just in case, we are offering a small tutorial.
This miracle sealant really is a miracle. It can work on almost any natural surface and offers a great bit of protection, indoors or outdoors. So even if you have outdoor kitchen countertops, you can use this sealer.

Step 6: Let Dry

There are many things that can stain the sealer. Stains on the sealer are rare but keep them away when you can. So spray with the all-purpose cleaner, rinse with a clean rag without cleaner on it, then dry it well.
Usually, you can just clean the countertop and add another topcoat. But if you want to stain them while you’re at it, then you’ll need to sand away the old sealer and apply the new coats after the stain has dried. 
The first thing that can happen is chemicals seeping into your food which is very dangerous. The second thing is the counter being easily scratched or stained, which will ensure you have to do touchups. So give it the three-day wait time. 

Step7: Sand And Repeat

It may only take eight hours for the sealer to dry but it can take up to three days for it to fully cure. So make sure you let it cure before using it unless you want to have problems later. These problems include two things.
The components of a kitchen are very expensive compared to those in other rooms. People care much more about having an expensive kitchen than they do about other rooms. And the focus is always on the countertops.

Is Concrete Countertop Sealer Necessary?

Concrete is quite porous so it is important to keep it well-protected. Without sealer, anything can seep into the pores and wreak havoc on your amazing countertops. So never use concrete countertops without a sealer. 

Keeping Your Countertops Looking Nice

Keep in mind that stains on concrete sealers are very rare and hardly ever happen. But it is always best to keep surfaces clean to give them their best chance at having a long and beautiful life in your home. 
We’ve already talked about the two primary sealers for concrete countertops. For our concrete countertops, we used both sealers. We started with the 511 Impregnator Sealer and then did the Safecoat Acrylacq. 
This sealer works very well as a top coat and can protect the countertop against damage. Pour some of this onto the countertop directly and get to work. You will immediately notice a shimmer despite the milky texture. 

This sealer will dry clear and you will be shocked at what it looks like when it does dry. If you see bubbles when you apply this sealer, then brush them away with a brush wet with sealer. Try not to leave bubbles.
