[MassHistPres] filingholes in histroic brick

[Scott A. Winkler, AIA]

Hi Marcia -

Silicone is not an appropriate material for brick repair, especially in
historic brick.  You should remove it while minimizing damage to the
brick.  Bricks should be patched with a repair mortar that is as close as
possible to the composition of the brick, especially in thermal expansion
and moisture/ vapor permeability.  Cathedral Stone's Jahn M100 repair
mortar does a good job of this.  If you have enough holes to fill/ bricks
to patch, they can test your brick and custom mix the mortar to be even
more compatible with your specific brick.  They will also do a custom color
match.

Good Luck!
