Buying Guide
Before providing you with a buying guide, we need to talk about the benefit of using the sealer. The sealer helps in avoiding damages caused by rain that penetrates crevices.
Thawing and freezing can also damage the walls and floors of your property. That is why you may use a sealer to prevent moisture from accessing the surface’s internal layers. Moreover, sealers help in preventing smelly and unsightly mold growth on the surface.
Now, we have presented you with how to choose the best sealer for masonry and brick surfaces. Buying the right sealer may not be easy, as you have to consider several factors to make your deal.
Penetration ability
The penetration power is one of the essential factors to buy a sealer. The best sealer works effectively to penetrate through any surface to prevent dusting and efflorescence. It should also alleviate the effects of weather elements. While buying the sealer, you have to identify its potential to penetrate the surface.
Eco-friendliness of the sealer
Masonry and brick sealers may have harmful elements in their composition. These sealers are not safe for your health and the surrounding environment. Thus, you have to check out the odor level and chemicals used for the sealer. The VOC level must be minimal to avoid any health issues. However, although your sealer may have low VOC content, it is better to put on protective gear when spraying it.
Outdoor and indoor uses
You may apply some sealers both outside and inside the house. But, there are sealers intended for a particular setting. Most of the manufacturers mention where you should use the sealer.
Other tips for buying sealers
How much sealer do you need?
You need to know about needs before buying the sealer. When you think of sealing a vast surface, it is essential to purchasing a big package. Manufacturers mention coverage rates for their sealers. For instance, 1 gallon of sealer may help you to cover 250 square feet.
Does the sealer work with some decorative surface treatment?
You have to check out the product compatibility before making a purchase. Some sealers can interact with coloring agents and overlays of the surface. This interaction can result in color bleeding, bubbling, blistering, and other issues.
To ensure minimal maintenance, it is vital to choose a sealer, which protects decorative overlay and concrete surface from weather elements and traffic. For instance, when you have a stamped concrete surface, you have to choose an oil stain-repellent sealer. The sealer must prevent water penetration and resist abrasion.
You can buy a solvent-based and water-based acrylic sealer for concrete flatwork. When you prefer the natural look of the surface, it is better to choose the penetrating sealer.
On the contrary, high-build sealers are perfect for decorative interior floors. The stain-resistant and scuff-resistant polyurethane sealer is also a good option. Softer acrylic sealers, used for indoor sites, need regular maintenance.
Check the drying time of the sealer
You can touch the acrylic sealer within 30 to 60 minutes of its application. However, you must wait for 12 hours after the final coat. Environmental factors, like humidity and temperature, may cause variations in the overall drying time. However, polyurethanes and epoxies need at least a 24-hour curing time.
Is the masonry sealer breathable?
Breathable sealers are best for outdoor applications, as they have a high water-repelling capacity. However, you will also find this quality in penetrating sealers. Some sealers are impermeable and may trap moisture.
Conclusion
Now, it is easy for you to find the best sealer for your brick and masonry surfaces. Most of the sealers are safe for applying to different surfaces. You can read our reviews and decide on the right sealer as per your needs.
