How to seal a brick wall/floor

How to seal a brick wall/floor

Sealing bricks can make them easier to maintain by protecting them from stains, moisture, and wear.

 

Here’s a guide to properly seal your brick floor.

1. Choose the right sealant

  • Penetrating sealers: These seep into the brick and provide a natural, matte finish without altering the surface’s appearance. Ideal for maintaining the raw brick look.
  • Film-forming sealers: These sit on the surface, creating a glossy or semi-glossy finish. They enhance the color and provide a smoother, shiny look.
  • Wet look sealers: Provide a darker, richer, and slightly glossy finish, mimicking the look of wet bricks.


Choose a sealant specifically labeled for brick or masonry to ensure proper performance.

2. Prepare the Surface

1. Clean thoroughly

  • Remove dirt, dust, and stains using a pH-neutral cleaner.
  • Allow the floor to dry completely. Sealing over moisture can trap it and lead to issues like efflorescence or discoloration.

2. Test the sealant

Apply a small amount of sealant in an inconspicuous area to ensure it achieves the desired look.


3. Application process

1. Protect surrounding areas

  • Use painter’s tape to mask edges where the floor meets walls or other surfaces.
  • Remove furniture and cover any nearby items to prevent splashes.

2. Apply the sealant

  • Use a paint roller, sprayer, or sponge applicator, depending on the sealant type.
  • Apply evenly in a thin, uniform layer.
  • Work in small sections to maintain consistency.

3. Allow to dry

Follow the manufacturer’s recommended drying time, which can vary between 24 to 48 hours.

4. Apply a second coat (if needed)

Some sealants require multiple coats for maximum protection. Apply the second coat after the first is fully dry.


4. Maintenance after sealing

1. Regular cleaning

Use a mild soap and water solution. Avoid acidic cleaners, as they can degrade the sealant.

2. Re-seal periodically

Depending on foot traffic, reapply the sealant every 1–3 years to maintain protection.



Additional tips

  • Ensure proper ventilation during application, as some sealants may release fumes.
  • Avoid walking on the floor until the sealant is fully cured.
  • Use a non-slip additive in the sealant for safety, especially in areas prone to getting wet.
