   Sandstone is a difficult material.  Tends to spall and erode away.

   What is the nature of the damage in this case, and wher is the water entering the structure?

   Hello

   the sill is badly weathered, and water now can seep under the window.

   Calking the window is only a Band-Aid, I would like to re-cap the hole sill. Something like you do on a chimney, the big problem is the sandstone it self. is there any way to make it more solid?

   I under stand the normal way of repairing sandstone it to remove it, and replace. but this window is 10 feet long and 8 feet tall. plus the stained glass is leaded,If the window can be removed, I don't like the kind of money that we are talking about to replace.

   You can cure rotten wood by injecting epoxies into it. Can something like this be done on sand stone?

   I was thinking of mounting pins in the stone and poring a cap of hydraulic cement.

   do you think this will work?

   any suggestion are welcome  .

   Thanks in advance!C.A.G.

   One option would be to cap the sill with metal somehow. Precisely how would depend on the details of the installation.

   Sounds like a very cool window.  You could definitely restore the structural integrity of it with epoxy, though the epoxy would need to be protected from sunlight afterwards.

   If you use epoxy, the 'pin' idea might work.  You could drill some holes, drive in some tapcons, then fill the void.  Alternately, you could drill oversize holes, partially fill hole with epoxy, and set any threaded fastener.  Epoxy bonds very well with porous masonry. As with any epoxy repair, the key to success is having very dry material for the epoxy to bond with.

   An expensive option is CYANACROLATE glue. It really may not make sense at first to you, but it will consolidate the stone.

   3m has many options as far as viscosity...I also think it may be marketed under the name "Pronto"...

   Thank you!

   I don't know what I will try yet.

   there is a smaller window that the problem isn't as bad yet, that I think I will try the play with first.

   Hilti has a glue insert stud set, I think if I use that first, and then build up a few posts, then I can make a forum to poor the epoxies into.

   are there any more suggestions on where to buy the epoxie? west marine comer to mind, Some one suggested a paint store. ( there are a few of those That I can check into.)

   Thanks.C.A.G.
