Buying Guide for the Best Waterproofing Brick Sealants

Choosing the right waterproofing brick sealant is crucial to protect your brick surfaces from water damage, mold, and mildew. The right sealant will extend the life of your bricks and maintain their appearance. When selecting a sealant, consider the following key specifications to ensure you pick the best fit for your needs.
Type of SealantSealants come in various types such as penetrating sealants, surface sealants, and film-forming sealants. Penetrating sealants soak into the brick and provide protection from within, making them ideal for long-term protection. Surface sealants form a protective layer on top of the brick, which can be good for short-term protection and aesthetic purposes. Film-forming sealants create a thick layer on the surface, offering strong protection but may alter the appearance of the brick. Choose based on whether you need deep protection, surface protection, or a combination of both.
BreathabilityBreathability refers to the sealant's ability to allow moisture to escape from the brick while preventing water from entering. This is important to prevent trapped moisture, which can cause damage over time. High breathability is essential for older bricks or bricks in areas with high humidity. Look for sealants that are labeled as breathable to ensure your bricks can 'breathe' and stay dry.
UV ResistanceUV resistance is the sealant's ability to withstand damage from the sun's ultraviolet rays. This is important for exterior bricks that are exposed to sunlight, as UV rays can degrade the sealant over time. Sealants with high UV resistance will last longer and maintain their protective qualities. If your bricks are in a sunny location, prioritize UV-resistant sealants.
Application MethodThe application method can vary between sealants, including brush-on, roll-on, and spray-on options. Brush-on and roll-on methods provide more control and are ideal for detailed work or smaller areas. Spray-on methods are quicker and more efficient for larger surfaces. Consider the size of the area you need to seal and your comfort level with each application method when making your choice.
Drying TimeDrying time is the duration it takes for the sealant to fully cure and provide protection. This can range from a few hours to several days. Faster drying times are convenient if you need to use the area soon after application, while longer drying times may offer more thorough protection. Choose a drying time that fits your schedule and the urgency of your project.
Coverage AreaCoverage area indicates how much surface area a given amount of sealant will cover. This is important for estimating how much product you will need. Sealants with higher coverage are more efficient and may be more cost-effective. Measure the area you need to seal and compare it with the coverage information provided by the sealant to ensure you purchase enough product.
DurabilityDurability refers to how long the sealant will last before needing reapplication. More durable sealants provide longer-lasting protection, reducing the frequency of maintenance. Consider the environmental conditions your bricks are exposed to, such as weather and foot traffic, and choose a sealant with durability that matches those conditions.
