If you’re making concrete candles, you’ll want to ensure that they last a long time and maintain their appearance. That’s where sealers come in. Sealing your concrete candles will protect them from moisture, stains, and other environmental factors that can cause damage.
But with so many different types of sealers on the market, how do you know which one is the best for your candles?
First, you’ll need to consider the type of concrete you’re working with. Different types of concrete require different types of sealers. You’ll also want to consider factors such as ease of application, durability, and longevity.
We’ll explore the different types of sealers available and figure out which is best for concrete candles.
Importance of Sealing Concrete Candles
You’ll want to seal your concrete candles to ensure their strength and stability, as well as to sustain their appearance and appeal. Sealing your candles will prevent cracking and chipping, and it will also protect them from moisture and other environmental factors that could damage them.
Additionally, sealing your candles will help to preserve their color and texture, providing a longer-lasting and more beautiful finished product. The benefits of sealing your concrete candles are clear, but there are also common mistakes to avoid.
One of the biggest mistakes is not allowing enough time for the concrete to cure before sealing. If you seal your candles too soon, the sealant may not adhere properly, and it could cause the concrete to crack or become discolored. Another mistake is using the wrong type of sealant.
Be sure to choose a clear, waterproof sealant that is specifically designed for use with concrete, and follow the manufacturer’s instructions carefully.

Acrylic Sealers
It’s common to use acrylic sealers to seal concrete candles. These sealers come in two varieties: water-based acrylic sealers and solvent-based acrylic sealers.
Water-based acrylic sealers are often preferred for their low odor and ease of cleanup, while solvent-based acrylic sealers offer a stronger, more durable seal.
Consider your specific needs and the environment in which your candles will be used to determine which type of acrylic sealer is right for you.
Water-Based Acrylic Sealers
Sure, water-based acrylic sealers are a great option if you want your concrete candles to look like they were made by a kindergartener.
Although they’re easy to apply and dry quickly, they’re not the most durable sealer out there.
Here are some advantages of using water-based acrylic sealers for your concrete candles:
- They’re easy to apply and dry quickly, making them a great option for DIY projects.
- They’re available in a variety of finishes, including matte, satin, and gloss.
- They’re water-resistant, which means they can protect your candle from water damage.
However, there are also some disadvantages to consider:
- They’re not the most durable sealer out there, which means they can easily chip or peel.
- They’re not UV resistant, which means they can yellow over time if exposed to sunlight.
- They can be difficult to remove if you decide to apply a different sealer in the future.
Solvent-Based Acrylic Sealers
If you want your DIY project to have a professional-looking finish, solvent-based acrylic sealers are the way to go. These sealers are tougher and more durable than water-based acrylic sealers, making them ideal for high-traffic areas.
Solvent-based acrylic sealers come in different types, such as high-gloss, semi-gloss, and matte. They also come in different finishes, such as clear, colored, and tinted.
One advantage of using solvent-based acrylic sealers is that they have better resistance to abrasion, chemicals, and UV rays. They also dry faster and have better adhesion to concrete surfaces.
However, they have a stronger odor and are more flammable than water-based acrylic sealers. They also require more safety precautions during application, such as wearing a respirator and avoiding smoking or open flames.
In addition, solvent-based acrylic sealers are more expensive than water-based acrylic sealers and require more coats for optimum protection.

| Provides a tougher and more durable finish | Requires more coats for optimum protection |
| Ideal for high-traffic areas |
Epoxy Sealers
You’ll love how epoxy sealers give your concrete candles a gorgeous, glossy finish that’s also incredibly durable.
These sealers are made of two components – a resin and a hardener – that are mixed together before application.
Once applied and cured, epoxy sealers provide a strong barrier against moisture, chemicals, and UV rays. They also resist staining and are easy to clean. One of the biggest advantages of epoxy sealers is their ability to enhance the natural beauty of concrete.
They come in a variety of finishes, from high gloss to satin, and can even be tinted to match the color of your candles. Some of the best brands of epoxy sealers for concrete candles include Rust-Oleum Epoxy Shield, Quikrete Epoxy Coating, and Seal-Krete Epoxy-Seal.
Polyurethane Sealers
If you’re looking for a sealer that’s durable and long-lasting, you might want to consider polyurethane sealers.
There are two types of polyurethane sealers: water-based and solvent-based.
Water-based polyurethane sealers are great for indoor use since they have a low odor and dry quickly.
Solvent-based polyurethane sealers, on the other hand, are more durable and better suited for outdoor use.
Water-Based Polyurethane Sealers
You might want to consider using water-based polyurethane sealers for your concrete candles because of their advantages.
These sealers create a clear and glossy finish on your candles, which helps to highlight their natural beauty.
They also provide a strong protective layer that shields your candles from moisture, dirt, and other contaminants.
This makes them ideal for outdoor use or areas with high humidity levels.
However, there are also some drawbacks to using water-based polyurethane sealers.
They tend to be more expensive than other types of sealers, and they can be difficult to apply evenly.
Additionally, they may require multiple coats to achieve the desired level of protection.
Solvent-Based Polyurethane Sealers
When opting for a more traditional approach, solvent-based polyurethane sealers can provide a durable and long-lasting finish on your creations.
These sealers are made with solvents such as mineral spirits, which evaporate and leave a hard, protective coating on the surface of the concrete.
Solvent-based polyurethane sealers offer several advantages such as high durability, resistance to chemicals, and UV light. They also have a fast drying time, which means that you can apply additional coats in a short amount of time.
However, there are also some disadvantages to using solvent-based polyurethane sealers. These sealers emit volatile organic compounds (VOCs) which can be harmful to your health and the environment.
They also have a strong odor that can linger for days, so it’s important to wear protective gear and work in a well-ventilated area.
Additionally, solvent-based polyurethane sealers can be more difficult to apply than water-based sealers, as they require more skill and experience to achieve a smooth, even finish.
Silicone Sealers
Like a protective shield, silicone sealers coat your concrete candles, guarding them against unwanted moisture and damage.
Silicone sealers are a great choice for sealing your concrete candles because they’re durable, long-lasting, and resistant to water, stains, and chemicals. They also have a high level of UV protection, which means they won’t yellow or fade over time.
When applying silicone sealers to your concrete candles, it’s important to use the right application techniques. Start by cleaning the surface of your candles thoroughly and allowing them to dry completely.
Then, apply the sealer evenly using a brush or roller, making sure to cover all areas of the candle. Allow the sealer to dry completely before applying a second coat if necessary.
To maintain the seal, avoid using abrasive cleaners or scrubbing the surface too hard. Instead, use a mild soap and water, and reapply the sealer as needed.
Natural Wax Sealers
Using a natural wax sealer is a great way to protect and enhance the beauty of your handmade candles. Eco-friendly options like beeswax, soy wax, and carnauba wax are perfect for sealing concrete candles.
These waxes are non-toxic, renewable, and biodegradable, making them ideal for environmentally conscious candle makers. One of the best DIY sealing techniques for natural wax sealers is to melt the wax in a double boiler and then brush it onto the concrete candle.
Be sure to apply the wax in thin layers and let it dry completely before applying another layer. This will ensure that the wax is evenly distributed and the candle is well-sealed. Natural wax sealers not only protect the candle but also add a glossy finish that enhances its beauty.
UV-Resistant Sealers
If you want to protect your handmade candles from the damaging effects of the sun’s rays, UV-resistant sealers are a great option for you. These sealers have a unique formula that provides an extra layer of protection against harmful UV rays.
The benefits of UV resistance are numerous; most notably, it helps prevent fading and discoloration of your candles. Unlike regular sealers, UV-resistant sealers also help prolong the life of your candles by preventing them from cracking or deteriorating due to sun exposure.
When comparing UV-resistant sealers, it’s important to consider the level of protection they provide. Some sealers may only provide minimal UV resistance while others may offer maximum protection. Additionally, it’s important to consider the application process of the sealer.
Ease of Application
You’ll love how easily you can apply the sealer to protect your handmade candles from the sun’s harmful rays.
When it comes to applying UV-resistant sealers on your concrete candles, there are different application techniques that you can use depending on the type of sealer you have.
Some sealers can be applied using a brush, a roller, or even a sprayer. It’s important to read and follow the manufacturer’s instructions to ensure that you’re applying the sealer correctly.
One of the best practices when applying sealers is to work in small sections and avoid overlapping. This will prevent uneven application and ensure that the sealer is evenly distributed.
It’s also important to apply the sealer in a well-ventilated area and wear protective gear such as gloves and a mask to avoid breathing in fumes.
Durability and Longevity
To ensure your handmade concrete candles last for years to come, it’s important to invest in a UV-resistant sealer that can increase their lifespan by up to 50%.
The sealer should be able to provide long term performance and resistance to wear and tear.
Here are three important factors to consider when selecting the best sealer for concrete candles:
- Chemical resistance: Your sealer should be able to withstand exposure to chemicals such as oils, perfumes, and cleaning agents. This is particularly important if your candles are meant to be used as decorative pieces in a home or office environment.
- Water resistance: Concrete is a porous material and can absorb water over time, which can cause damage to your candles. A good sealer should be able to protect your candles from water, preventing any damage due to moisture.
- Scratch resistance: Candles can easily get scratched or damaged due to regular usage or handling. A sealer that provides scratch resistance can help protect your candles from any unwanted scratches or marks, ensuring that they look as good as new for longer.
Final Verdict and Recommendations
Now that you’ve considered the factors for durability and longevity, it’s time to make a final decision and choose a sealer that’ll protect your handmade concrete candles for years to come.
Some products are highly recommended by experts when it comes to product recommendations.
One of the most popular sealers is the Ghostshield Lithi-Tek 9500. It’s a penetrating sealer that provides long-lasting protection against water and other damaging elements.
Another great option is the Concrete Sealers USA PS101. It’s a solvent-based sealer that’s perfect for outdoor applications.
It’s important to follow a few key tips when applying sealer to ensure that you get the best results.
First and foremost, make sure that the surface of the concrete candle is clean and free of any debris or dust.
Additionally, it’s important to apply the sealer evenly and in thin coats, using a brush or roller to ensure that you cover every inch of the surface.
