Loose coping stone

34
Posted 19th Oct
I have a similar coping stone to that in the pic, which has come loose from the brick pillar.

We took the stone off and poured ready mixed mortar over the top of the brick pillar, then put the coping stone back. When the mortar dried we had expected the coping stone to stay in position but it is still loose.

Have we not done the mortar correctly, like not enough mortar or is there a better method to stick the coping stone back on to the brick pillar?

We? How many people did it take to do (or not) that?

I do hope you find a successful resolution though

Deeks won't be able to cope with this one.
Its not the correct way to do it but pink grip will stick it on solid just make sure its dust free and no loose bits on both surfaces and put loads on and youll need a hammer to get it back off

I'd use a foaming polyurethane adhesive to bond it, really waterproof and sticks to most things including concrete. You'd need to moisten one surface and apply glue to the other. Don't go close to the edge as it will expand and you don't want it getting on the brickwork.

I'm not sure about it being outdoors to be honest all i know is ive stuck many items to brick with it before and they were solid the next day but have to make sure they are dust free etc.
Maybe wait for better advice ? But i know my skirting ive stuck directly to blocks is not coming back off without a fight and i used it to stick plastic cladding to my ceiling and walls in my bathroom and it seems like it will rip the plaster off when i try to remove it in future, its solid
Congrats on 1112 not sure how or why you do it but fair play to you it brightens our days and makes us realise how lucky we are in life.

'Ct1'same sort of thing as pink grip works outside all weathers.

Wickes used to stock a very good building adhesive which would have sorted this no problem. Unfortunately I've never found another product which comes close to it for strength but Pinkgrip looks like it might be worth a try.
Mutley, here’s one for your scrap book in case you ever remove your dishwasher or even washing machine.

Just buy some sand and cement, mix at 3 parts sand to 1 part cement and it will hold.

Readymix isn't any good.
If you do use mortar to bond it, you should make the coping stone and the wall wet before applying it, otherwise the stone and wall will suck the water out of the cement and it will dry too quickly and not stick. I would also add PVA or other suitable admix to improve the bonding strength.

For one coping stone it is quicker to just moisten it and use a PU adhesive as I mentioned above, its very strong and 100% waterproof.

Here's someone using Gorilla glue (which is just an overpriced PU glue) to build a whole wall

that looks like for wood though? it says that you can use it to glue wood to concrete but not sure if this means the same as concrete to concrete.

this sounds more logical. i just can't see how a stick of glue is going to be hardy enough to stick a block of concrete. this sounds more likely to work better, considering now there is a layer of mortar that we have spread on the top of the column that has hardened but has done diddly squat for retaining the coping stone.

that is not our wall. mine is slimmer but it is the only one similar to ours that i could find on the net. ours is about 2/3rds of that and the coping stone is only on the pillar and not the wall itself.

i have noticed that ready mix mortar is not very strong when it dries. it is sort of flaky, if that is the right description. what is it used for if it is no good?

Providing it is their "original" PU glue, and not their PVA wood glue.

You must make one of the surfaces slightly damp, but don't soak it, PU glue requires moisture to activate it. Gorilla glue is marketed for sticking stone etc :- uk.gorillaglue.com/gor…al/

I wouldn't build a whole wall with it though


I have used gorilla glue to reattach a coping stone, and have used various other brands of PU adhesive for bonding wood and other materials to walls and also for repairing boats.

I got that tip from a builder after asking them why mine kept falling off. Used it and they haven’t fallen off so far.

Tried the resin trick the year before after a winter they all came off. SBR is the best option.

Why would you not show your actual wall instead of some random picture from the internet?
You own a camera don't you.
