Dilute a cleaning solution that contains bleach or a mild detergent by mixing 1 part solution with 10 parts water in a bucket. Remove all furniture from the surface and scrub the bricks with a stiff-bristled scrub brush and the diluted mixture. Hose off the remaining soap and wait for the bricks to dry completely.
Examine the grout between the bricks for any pits or cracks.
Mix a batch of thin grout with 1 part cement, and enough water for a creamy consistency if the grout damage is not severe. Use a putty knife or your finger to fill in the cracks or holes.
Remove the damaged grout with a grout removal kit if the cracks in the grout are deep. Once the grout is removed, mix 1 part cement, 1 part water and enough water for a stiff consistency, and then apply new grout between the joints with a caulk gun or putty knife.
Apply a solvent-based sealant to the bricks to seal the patio surface with a roller brush or spray pump. The sealant will preserve color, increase the longevity of the grout and protect the surface from water and weather damage.
