Fastners recommended to anchor metal to OLD brick

Hi All,

Just wondering if anyone has some advice about anchoring a metal railing to old brick. This is a Handicap Stair Railing, but the brick is OLD brick and rather "crumbly." Any recommendations on fastners to use that won't work loose or crack the brick?

Use HILTI or similar epoxy anchors. These will hold well in iffy brick and concrete. See if you can get their catalogue for installation guidance. It makes a difference if the bricks are solid or hollow. And blowing & brushing out the drilling dust is important for the anchor integrity.

There isnt any. Epoxy systems may keep the fastener secure..but if the brick is crumbly(mortar)..pulling on the rail may pull the entire brick out of the wall.

Iffen ya got access to some sulphur--drill a big hole -place a bolt init-melt the sulfer-(carefully--it likes to burn)--pour it in the hole--(blow out dust--can't be wet either!!) Solid chunks melt easier than powder--Usta come in a slightly tapered form-2" +- in dia -6 to 10" long---Called 'em Cones--wunder why?-- Doesn't shrink upon cooling--thas why it werks so good--but they had to get it out of the molds, so--- tapered.. Voilla!

Yes, sulphur in the plastic state is a good way to anchor iron. The fine wroughtiron work of the 19th century was anchored that way and is holding up well (concrete/mortar in contact with iron in wet conditions causes rust).

For vertical walls, it's OK to drill the mortar and use lead anchors.

I've heard that drilling brick is not recommended (brick is vitrified on the surface and weathers well, but the core material is less durable).

How thick is the brick? Is it all brick or just a fascia? If just a fascia I would drill through the brick and anchor to the interior substrate. Brick itself tends to crumble once the outer layer is breached.

It's worse than that with some old brick. They're baked, but not vitrified. I've seen them turn back to dirt when exposed to soil and weather.

Not to drill the old lime junk. Drill the brick. If it is to far gone, then there isn't any strength within it.

If you have access to the back side for some easy reason - then maybe a metal plate or metal bar matching the line of connections - and through bolts.

I'd be very cautious. Consult with a brick mason.

This could be a legal issue.
