Brick and mortar repair

Doing brick and mortar repair can be time consuming, messy and difficult.   If the color is off, or if mortar is smeared on the brick, the brick and mortar repair will draw even more negative attention to the area.  That is exactly opposite of what you are trying to accomplish, right?  Here is a trick of the trade that will make brick and mortar repair easy for anyone to do!


















We all know that tile grout comes in a wide variety of colors.  You may also be aware that these manufacturers also make caulk to match.  Most professional tile setters use this sanded caulk on the inside corners of tiled surfaces.  I have found this to be a quick and easy solution for brick and mortar repair on the exterior of homes.


First get the color of the mortar matched by bringing a small piece of the mortar from the wall you will be repairing.  Hold it up to the color chart that is available at either tile stores, or home improvement centers.  Make sure you buy the “sanded” variety, otherwise you are just buying a colored caulk that will not have the sand texture in it that makes this trick of the trade work so well.



Know that you have the sanded caulk that matches just cut the tip and fill the voids and cracks!  Its that easy!!  This old brick house had some major damage right at the front steps.   Look how good it looks now!  The color will dry a little darker and be a perfect match.




This type of caulk is water based and will clean up with a wet rag and water if necessary.  If you can squeeze it evenly and can prevent the need to run your finger over it, that is the best way to guarantee you do not smear it on the rough edges of the brick around the brick and mortar repair.

    The Keracaulk instructions specifically state, “Interior space only. Not for use on areas prone to water exposure. Cure for 72 hours prior to water exposure.” The Mapei (manufacturer) warns against using this on exterior areas…so that precludes repointing brick mortor outside!!

      Thanks for visiting my blog and posting your comment! You are absolutely right that the manufacturer does not recommend that this product is used in wet areas. However, it does work, and I personally have not experienced any problems using it on exterior walls making minor cosmetic repairs. That being said, that does not mean that this is the best (or correct) solution for all brick and mortar repairs. There are times that repointing with mortar is necessary and best, especially when the structural integrity of the wall or chimney has been compromised due to deterioration of the mortar. This is just a simple suggestion that helps make small, cosmetic repairs easier for DIYers.

    This is exactly what I was looking for! I have a front porch that the mortar between the bricks was starting to crack out. When we bought the house, the porch wasn’t covered, but we had one built. I felt like a caulk would work, and you have enforced that thought. My husband tired to “fix” it with some gray stuff he bought, and it sticks out like a sore thumb. I am absolutely thrilled to know that I can use the sanded caulk, and get the exact color I need. Thank you, thank you, thank you!

      Keep in mind this is a purely cosmetic solution. Most brick walls these days are purely decorative anyways. Hands down it is the quickest and simplest way to repair crumbling mortar on a brick wall. Thanks for your comment and thanks for visiting! Its good to hear positive feedback! -Steve Trump
