How To Seal Exterior Brick Floors

Brick floors can add style to any exterior area or pathway. You can lay out your brick to make your floor completely unique. It is a relatively affordable and easy to maintain product. However, brick floors do take some maintenance over the years. This article explains how to seal and clean brick floors in an outdoor setting. This simple process protects the mortar and preserves the color of the bricks.

To Clean or Not to Clean

You can seal your brick to maintain the color, but you have to decide whether or not you are going to clean it before. Exterior brick will absorb dirt and start to look aged. Some homeowners embrace this look because they think it makes their floor design look unique and antique. If you want to keep this aged look, you can apply the sealant without cleaning the brick.

However, if you want to restore the original, rich colors of the bricks, you can clean them first. The best way to clean a brick floor is with a pressure washer. You don't even need to use any soap or trisodium phosphate in most cases. Pressure washing is time consuming, because you basically need to hit every square inch of your floor with the stream of water. So, expect it to take a while. You will also need to let the bricks dry off completely overnight before sealing them the next day.

Sealing the Floor

Sealing brick is easily done with a pump sprayer. This allows you to evenly spray the sealant all over the brick and mortar. The sealant won't ruin most surfaces, but you should still mask off the areas around the floor so nothing gets damaged. For instance, a hardwood deck or window frame should probably be taped off so the sealant does not stain the wood. Sealant protects the brick from water damage, so you want to cover every square inch of the floor. The sealant will soak into the brick, so you don't need to wipe it away. Let the first coat of sealant dry for a few hours before applying a second coat.

The difficulty of sealing your brick floor will largely depend on your home design and how thick the grout lines are. The job does not require any special skills, but can get dirty and very tiring because it requires so much bending down on your hands and knees.
