Guide on How to Refinish Interior Brick Floors

Quck answer

Refinishing interior brick floors is a process that involves cleaning, repairing, and sealing the bricks to enhance their appearance and durability. The first step is to remove any dirt, dust, or debris from the surface using a broom or vacuum cleaner. Next, inspect the bricks for any cracks or damage and repair them using a brick patching compound. Once the repairs are complete, apply a brick sealer to protect the surface from stains and moisture. Finally, use a floor buffer with a soft pad to polish the bricks and restore their shine. Regular maintenance, including sweeping and mopping, will help keep the floors looking their best for years to come.


Interior brick floors are known for their durability and timeless charm. However, their dark tones may not always complement modern home decor. If you want to lighten or update the look of your brick floors without completely painting over them, whitewashing is a great solution. This technique involves rubbing watered-down paint into porous pavers or tiles to refinish brick floors while preserving their natural texture and rustic beauty.

Step-by-Step Guide on How to Whitewash Brick Floors

Step 1: Clean the Brick

To prepare the brick surface for whitewashing, thoroughly sweep or vacuum the area to remove loose dirt, hair, and dust.

Step 2: Remove Wax or Grease

If there is any wax, grease, or polyurethane on the brick, it needs to be removed before whitewashing. Wear long pants, gloves, safety glasses, and a mask or respirator. Use a product like trisodium phosphate (TSP) to strip the brick. Mix TSP with warm water according to the label’s directions and scrub the bricks well with a sponge. Rinse with clean water and allow them to dry completely.

Tip

To make kneeling on the hard brick surface more comfortable, use a yoga mat or garden kneeling pad.

Step 3: Apply the Paint Mixture

Pour a small amount of watered-down paint into a shallow cup or container and do a spot test to determine the correct ratio of water to paint for the desired opacity. You can choose acrylic, chalk, or grout renewal paint in white or off-white. Work in small sections, applying the wash mixture into the grout lines using a paintbrush or old toothbrush. Use a damp cloth to rub the paint into the grout and then wipe it over the entire surface of the brick.

Step 4: Smooth Out Uneven Areas

Go over the bricks with a dry cloth to smooth out any areas where the paint is uneven.

Step 5: Repeat the Process

Repeat steps 3 and 4 until every brick (including grout lines) is whitewashed to your satisfaction. Touch up any areas that need it and allow the whitewashed brick to dry.

Step 6: Optional Protective Sealer

If desired, apply a water-based, protective polyurethane sealer in a matte, satin, or semigloss finish using a paintbrush or paint roller.
