Sealing brick pavers can provide several benefits for your outdoor surfaces, such as:

1. Protection from the elements: Sealing your brick pavers can help to protect them from the harmful effects of rain, sun, and other environmental factors. This can help to prevent fading and discoloration, and can also help to prevent the growth of mold and mildew.

2. Easy maintenance: Sealing your brick pavers can make them much easier to clean and maintain. A sealer creates a barrier that prevents dirt and grime from penetrating the surface, making it much easier to sweep and wash away debris.

3. Enhancing color and texture: Sealing can enhance the color and texture of the brick pavers, making them look more vibrant and new.

4. Preventing weeds and ants: Sealing can prevent weeds and ants from growing in between the pavers.

5. Durability: Sealing can help to extend the life of your brick pavers by protecting them from the wear and tear caused by foot traffic and other factors.

It's important to note that sealing should be done on clean and dry surfaces, and also that not all sealers are created equal. It's recommended to use a sealer specifically designed for brick pavers, and also to re-seal every 2-3 years, or as needed.
