wall cabinet that's going next to window. The old one was right in the corner of the last brick (rawlbolt) after that its just filler and a scrappy wooden lintel and gaps. The new fixing needs to be right in the "hole". What do I do? Cut a brick to fill the space and cement it in? If so how long will the cement next to go off?
"Mike......." asked;
Mortar is normally used to bed a brick to other bricks in a wall. You could possibly use concrete (cement and sand) to fix a brick in place. Mortar should have set after 24 hours at the most, and concrete should have set after 48 hours at the most.
thanks, I was thinking concrete as its going to be a essentially bodged up repair of a space left by badish DIY 30 tears ago. Would concrete give more strength?
my inclination looking at the hole is that putting a third of a brick in would give something to fix to but how secure will it be with a bit of mortar poked in as best you can? If I push a load of cement in it will conform to the irregular shape and wont be able to fall out because of it shape?
in meant cement
What is mortar if not cement and sand? (OK, it might be lime mortar, but I wouldn't recommend that here).
To the OP:
The Natural Philosopher will be along shortly to say "car body filler"
- and this might well be a good application.
I can't visualize the situation, but I would hesitate to use concrete in any application that requires tensile strength - it is very strong in compression, but if you pull it even a tiny bit, it will crack.
In similar circumstances, when hanging a row of cupboards, there was nothing substantal to bite into for one of them, so I hacked out the loose stuff and filled and drilled with
never thought of that!
its in an irregular shaped hole that should have been a half brick, if fancy polyfilla did the job, im hoping cement will. It has nowhere to go so shouldnt crack?
Ah right. That should be fine.
