Glue for bricks

Something I get asked to do quite a lot is repair brick pillars - sort of thing you find at the end of a low garden wall.

Usually a 'lump' of brickwork is loose e.g. 3 or 4 bricks which are themselves firmly held together by the mortar.

Rebuilding means separating the bricks, chipping off the old mortar (not always easy) & re mortaring in the usual way. Time consuming.

Are there any adhesives capable of just gluing back said lump? Epoxy or one of the latest grab adhesives?

Obviously have to be pretty strong.

I have used plastic padding type hard and its successors in name for a ridge tile and various other bits of masonry over the years.

Current name seems to be

Unibond Repair Metal for Good

It is a 2 part filler/adhesive and refers to its ability to stick metal to wood and masonry. As always it is necessary to clear dust off the surfaces first.

Car body filler :-) Seriously, I've done 2 or 3 (including my own, which is still solid and holding a hefty gate hinge after 5 years). If you ever get up the A20 as far as Sidcup, there's a cheap place at The Oval. 3.5 litres Bondaglas Easy Sand with hardener x4 about £12 last time I was there.

I'd be inclined to drill a hole in both sides of the break and put something in like rebar - but might rust. Make one hole a bit bigger than the other for adjustment purposes. Just something so you get mechanical reinforcement of the joint, Then some kind of "glue". I would feel more sure of not getting a call back and "its broken again" when some local chav has done his chav thing on it. Simon.

Just thought. What about some of the "thinset" mortar. Now that is basically glue for bricks ! SImon.

Elch polyurethane (Screwfix Quote No: 79242) says on the container:

"Excellent adhesion to wood, chipboard, laminate, metals, polyurethane, polystyrene, formica, mineral wool, concrete, stone, bricks and gypsum boards."

I have used it for block/brick (minor repair). Seemed to work well. It was that experience plus information about Fischer's Fix and Fill that encouraged me to try it for loose wall plugs. For which it also appeared to work fine. I included some stainless screws to hold the material as the glue set. (Though I would agree with Andy, resin is probably more predictably strong.)

Of course, there is always resin...

Polyurethane. Wet the surfaces and it will foam up nicely to fill all the gaps. Will be a sod to get off if it dribbles out though! Foam filler might also work (Its basically more foamy PU adhesive).

If it's just the joint between mortar and brick which has cracked so the bits drop back together cleanly I've always found ordinary PVA perfectly good - quite a few bricks in our garden walls are held together with it and have never given any problems.

Just using 'glue' might be a bit ineffective if the mating faces have had soil or whatever leached into the crack. You'd really have to thoroughly clean and dry the faces; it would be a lot easier to clean off the old mortar and do the job properly.

Dave,

Any resin product which is used as part of a chemical anchor system will outlast us all.

e.g. Screwfix 84891

in fact, any of this stuff can be adapted: -

Any of the adhesive resins will do it, epoxy being the toughest. Big time saver over a rebuild, if the damage is light enough.
