info about paint removal from historic brick

[Betsy Kellums]

I just met with an architect who indicated the owners of a 1956 Moderne style building with painted brick want to sandblast and remove the paint.  I thought I had some resources to share with him about exterior paint removal from brick but I can’t seem to find them.  The only thing I can find right now is the SOI Rehab Guidelines for Masonry.  I would appreciate any resources you might have that I can pass along to the architect to share with the building owner.

 

Thank you!

National Park Service Preservation Briefs, Tech Notes, 

This is an issue that has been discussed for at least 30 years, It is hard to believe that people still want to sandblast.  There are many chemical ways to remove paint safety without damaging the brick.

Betsy,

 

Look at Preservation Briefs 6 on the “Dangers of Abrasive Cleaning to Historic Buildings”.  Here is the link:

Another thing to discuss is whether perhaps this building has always been painted. If so, the masonry below the paint may not be as uniform as they'd like.

We have lots of photos of why you shouldn't sandblast brick. I'm happy to come discuss it with the architect, if you need back-up.

Thanks, Gheda

We remove a lot of paint from historic brick. We are, for the most part very successful in doing so and do almost no damage to the brick. This is the toughest thing we do in masonry preservation.  It's is a process that can be timely and expensive.  I would be happy  to discuss our process and even consult with your contractor.

One more thing , we would never recommend any  type of sandblasting.  It removes the patina or surface of the brick causing  great damage. If done properly  the paint can be removed  and the brick restored  back to the it's original form and appearance.  Terry

Good Point, this is true in many cases.  The paint was used as a covering for using poor quality bricks, usually as an original cost saving measure.
