A coating of plaster, rendering, is  applied to stonework.   You may notice cracks in the rendering.  There are several different methods of filling in these crack and the most commonly used methods are as follows.

For Small Cracks:

  • Get rid of any loose coatings and particles of masonry.
  • Apply a filling agent - exterior grade filler,  but this will probably re-crack after a short period of time, but an exterior acrylic caulking will provide a better flexible repair.


For Large Cracks:

  • Rake out, undercut and fill as above and then allow to dry.  A bituminous caulking compound can now be applied over the crack and then bed a nylon tape over the length of the crack.  Further caulking compound can then be applied over the bandage to provide an invisible reinforced repair, which will last longer than a cement based pointing up repair.
