Buyer’s Guide to Concrete Sealer

Concrete sealers are an essential part of any construction project, providing a layer of protection and enhancing the overall durability of your concrete surfaces. However, the myriad of options available can make choosing one quite challenging. That’s why this guide will help you navigate your way and ensure you make a smart, informed choice.

Type of Sealer

First things first, you need to decide on the type of sealer that best suits your needs. Penetrating sealers penetrate the concrete to form a chemical barrier that shields against moisture. They are a great choice for exterior surfaces as they offer excellent durability and do not change the appearance of your concrete. On the other hand, topical sealers create a protective layer on the concrete surface and are ideal for indoor spaces due to their aesthetic appeal. They come in different finishes, including gloss, matte, and semi-gloss.


Performance is all about how effectively the sealer can provide the protection you need. Some products offer superior resistance against water, salts, and other chemicals. Others excel in enhancing the aesthetic appeal of the concrete, providing a glossy shine or a wet look. Evaluate your requirements and choose a sealer that performs exceptionally in those areas.

Ease of Application

When buying a concrete sealer, take into account its ease of application. Sealers are available in different application modes, including sprayers, rollers, or brushes. Some may require professional expertise to apply, while others are DIY-friendly. Consider your comfort and proficiency level with the application methods before buying.

Drying Time

The drying time of the sealer can influence your project timeline. Some sealers dry quickly, while others may require up to 72 hours before completely drying. If you’re working on a time-sensitive project, opt for a fast-drying concrete sealer.


Of course, price is an important factor in any buying decision. The best concrete sealer doesn’t always have to be the most expensive one. Rather, consider the value the sealer provides. A high-quality, long-lasting sealer might be a little pricier upfront, but it may save you money in the. long run as you won’t need to reapply it frequently.

Brand Reputation

Finally, don’t overlook the brand’s reputation when buying a concrete sealer. Established brands usually have a track record of producing reliable, high-quality products. Check out online reviews or ask for recommendations from industry professionals to find a brand you can trust.


Finding the perfect concrete sealer can feel like a daunting task, but with this guide, you know how to make the right choice. Evaluate your requirements and consider the factors above, and you’re sure to find a product that ticks all your boxes.
