Adhesive (glue) for Brick Shelf Supports

18 years ago

I tried this on the "home repair" forum, not a lot of input.

Any advice here?

My fireplace has two mantel supports made from brick (used brick, old brick) that are formed by three bricks installed with the length perpendicular to the face of the brick wall. Each brick sticks out about 1/3 of its length. The top, which is mostly exposed broke at about the mid-point.

Is there a modern adhesive that I can use to "glue" the brick part back in place? The mortar that was under the brick is fully there, i.e., if the brick piece is "glued" back the mortar will not need "re-pointing" for appearance sake.

I suppose I can use some fresh mortar, but it would still be stronger if I could use some type of adhesive on the face of the fracture.

I do have a tube (caulking gun type application) of mortar patch, grey in color, but it doesn't say anything about being an adhesive, though it must have some "sticking" properties.

The repair will not have to bear much of a load, perhaps 30 pounds maximum, and that is in compression, with some "torque" at the break-point which is about 1 inch plus behind outer edge of the undlying supporting brick.

Yes.

There are adhesives used to glue sheets of "brick" (cast concrete, usually) facing onto cast concrete foundations.

Similar adhesives are used to glue capping stones on precast "stone" walls.

You'll probably have to hunt around for it, and it's not cheap, but you will never have to worry about it failing.

Thanks on on the tip on special adhesives, I'll check first with Home Depot. They do sell a lot of DYI that requires one to glue or cement things together.

drystonemason - thanks for the offer! I wish you lived in Colorado. My husband and I have a 70's wall o' brick. Really, the entire back wall of our den is covered in blond brick and the sides have custom built (70's style) cabinetry over the brick. We are planning to rip the cabinets out but our question is, what is the best way to reface this much brick? We plan to put travertine tile below the mantel to break up the look but on the rest of the wall, from what we have read, we have a few options. 1) Use a lime based plaster (not drywall compound) to fill in grout lines and eventually build up and smooth out to a rough, toweled on surface 2) Use mortar and stucco to achieve the same look. 3) Using drywall we can either frame out the whole wall and start over or use liquid nails (a lot of it) to put sheetrock on the areas that are not tiled. Hoping you might have some suggestions on what the easiest route would be considering it IS a whole wall. I will see if I can get a picture to insert which might be helpful.

My 'junk drawer' shelf, FINISHED!! Before & after pics

thanks! And here's the other suction-cup wall pocket intended for the bathroom that I pressed into service. Before the flashlights stood on that section of the shelf. You had to reach around the tape dispenser to get to them, and they'd fall over, etc. (bcs you were usually reaching for them in the dark) Yay for heavy-duty Scotch mounting strips! also note where the hammer is. If I'd put it on the strip at the top, it would have taken up the entire strip. At first, I just left it standing on its head in the corner, but I wanted that space for the electric screwdriver, and I didn't like that it was loose. I'd purchased a 7"-long magnetic strip, so I put it deep in the triangle area, where it's hard to store anything else, and stuck the hammer to it. Keeps the hammer out of the way, in the same spot always, and it won't fall over, etc. Also note the gap BEHIND the drawer unit, and the note on the wall. In that gap are some things that I wasn't willing to get rid of but may not need anytime soon--like extra bleach pens, extra trash-can bags, and the magnetic strips that go w/ the blackout curtains. And on the left, Command hooks (and some other off-brand stick-on cup hooks) for the extension cords--this is really having a big effect, too.

I know this is not going to help the original questioner posted in 2007 and I sure wish I had found this question back then... But for those of you looking for "THE" answer... hear you go. The Amastin Company, Corryton TN, has been providing steel support bars in supporting hard surface counters to the East TN market since 1995. In this particular case, which is a common one, Amastin offers a 31" long x 2-1/2" wide x 1/2" thick steel support bar that would bump and mount into the back of the front face frame, notch and recess flush across the back cabinet mounting strip. This support would overhang 8" leaving it approx 4" from the counter edge making it virtually hidden. Amastin has the overhang support thing figured out and if you have any questions or in need of custom support advise... Amastin is place to find the answers.

Pantry shelf question

Just make a but joint and glue the shelves together. Adding biscuits or even dowels can help with alignment during glue up, but the glue will be stronger than the wood itself if you have the correct even thin film of glue with an otherwise tight joint. If you use plywood for the shelves you can have a single piece with no joints at all up to the size of the plywood sheets. 3/8 thick AC plywood with a hardwood edging on the perimeter (about 1 inch by 1/2 inch edging) makes adequately stiff shelves for most uses. I put the edging under the shelf on the back ad above the shelf on the front to keep things from falling off while preserving as much shelf space as possible. If you use hardwood for uprights they only need to be about 1 inch x 1 inch. You can fasten them to drywall using Wall Dog type screws and just build everything in place. Watch out for out of flat walls in the corner from drywall mud. You can carve some of the mud away to clear the edge banding. The last pantry I did had 'U' shaped shelves 4 feet wide, 2 feet deep with a 12 inch deep x 2 feet wide cutout to make the 'U.' 1 inch x 1 inch verticals (4 along the back wall, 4 along the front, nothing on the inside shelf corners). The final touch was 3 low voltage puck lights (20 w each) on the ceiling with a door operated switch and 24 VAC relay. The relay wiring is all standard HVAC control stuff (transformer and relay) and switches the 120 V side of the AC to DC supply for the pucks. The pucks are on a piece of 1x4 on the ceiling mounted against the door wall. This post was edited by brickeyee on Wed, May 15, 13 at 11:31

You MAY find it at a home depot.

Another possible solution is one of the new polyurethane glues...

Gorilla is one brand name. You have to watch those, though, as they expand as they cure, and you can end up with the pieces either being forced apart or with unsightly drips.

Gorilla was mentioned when I posted this question on the Home Improvement forum. I've never used Gorilla, it must be something.

The application isn't very critical eye-sight wise. The broken brick, when reparied will be mostly covered by the (new) mantel resting on it and extending several inches beyond it. I will also add a face board to the mantel, making it look much thicker (maybe some molding) and that too will block seeing the undelying brick bracket.

You can drill a 3/8's or larger hole in both pieces and put a metal rod obtailable at HD and fill with quick setting epoxy both sides and shove the metal rod in.This way it will support the weight with no problem. and should be as strong as new Also put some epoxy around the both ends of the brick as extra insurance... 1/2 inch rod may be better up to you ... Be sure to go in at least 1/2 to 3/4 on both ends
