Patching up a front garden wall today for a neighbour – spalled bricks from snow & frosts – about a dozen of them that have a similar depth damage to the photo below.

Anything I can do to maximise chance of staying on for more than 2 minutes? (many of them are their previous bodges that have inevitably come off again – but this is what they’ve asked for)

Thinking:

1. Brush free of dust.

2. Don’t laugh – drill a couple of holes at opposing jaunty angles.

3. Plug holes and brick face with a sharp sand mortar and smooth flush.

Wall will then be repainted in hideous pink which should hide any sins.

Thanks 🙂

Get some SBR, use a dilute mix as a primer and then add to the mix that you make up.Sticks like poop to a blanket is waterproof and then frost resistant. Will go off rock hard so don’t mix too much in one go or leave your tools dirty.

Drilling holes won’t really help it to bond so a waste of time and effort. Score it with a grinder if you are going to bother with making a keyed surface but SBR prime and mix should avoid that need.

Easier but more expensive method would be to use a hardcore exterior filler such as Toupret Murex.

That Toupret Murex stuff does look easier – that’ll do. Cheers 🙂

Where is the moisture coming from? Ie is it rain/snow on the front face or is the wall a retaining wall with wet soil behind it?  My experience of the latter is that not only makes any fix shortlived but means it can be very difficult to get the wall dry enough to get anything to stick properly in the first place.

It’s been from the front face, it’s not retaining anything but good thought thanks.

For anyone googling, after checking wall & much more of it needing to come off, that Toupret Murex is bloody awesome – expensive & goes off very quickly (30mins) but stuck like stuff on a blanket, didn’t sag & really easy to apply smoothly & even form perfect corners with an extra, wet, trowel. 10 mins after applying, a wipe with a wet sponge and it all looked far better than my skills should allow.
