  • Step Three: Then get a masking tape and wrap the top of the bricks. This is to ensure that when the mortar is applied, it would not fall off. Aside from that, it would make your chimney crown repair look like a professional’s work. 
  • Step Four: Guess it’s time to use the mortar. Mix the mortar and scoop with your trowel and apply gently on the affected area. Use the trowel to rub in the mortar gradually into the affected part.
    After you have applied the mortar on the chimney crown, spar water softly on the mortar. You don’t have to wait until the mortar has dried off before you sprinkle the water gently on the mortar. The essence of sprinkling the water is to make the surface of the chimney crown look very smooth.
  • Step Five: Finally, remove the masking tape after you have finished applying the mortar. However, you may choose to remove the masking tape after the mortar has dried off or after a few minutes of applying the mortar.
    Whichever you choose, make sure to remove the masking tape gradually so it doesn’t affect the job.
