Radiator fell off - can’t get brackets back on

[JohnD]

It is a brick wall behind the plaster as the wall on the other side is the one facing the street made fully of bricks.

Then drill into the bricks, use plasplugs and long screws.

The plaster and filler have no strength.

Have you got a drill?

What is behind the plaster?

It’s paint, skimming, plasterboard, then brick. However when I was drilling, I saw a fully black sort of rock. Not sure if it was brick or not. The wall on the other side (facing the street) is fully brick however.

Yeah, I’ve got a drill. This is exactly what I did today however the brick already had a hole in it and stupid me carried on drilling, widening that hole. So now the brick is already drilled into and too big for any screw or wall plug so I’m not sure where I should screw the brackets now.

Defective burned bricks used to be used for indoor walls that would be plastered and not seen. To my eye they have a hint of purple.

Breeze blocks were formerly made, of broken furnace waste with a trace of cement. They are grey and have the texture of lumpy porage.

You can drill into either, though burnt bricks can be very hard

Post photos please.

How big?

How thick do you think I should buy the ply? And do I use black wood screws to screw it into the wall or is it okay to use the gold ones? And will I need wall plugs or do I just screw the ply straight into the wall. How many screws shall I use?

16mm ply should do it, fix it to the wall between where the brackets go, and the outer edges, to the left and right, three fixings each side. 75 x #10's should do it, use brown wall plugs. You will need a sds drill, or maybe get away with a hammer drill, to drill the holes.

Answer, and I'll tell you how.

The brackets should have several holes pre drilled in them. If not, drill some more using a sharp metal drill bit.

It looks like a brick wall, behind the plaster, so cavity wall fixings are entirely the wrong thing to use.

Yup, you are correct. I did not look closely enough at the photos. I hadn't realised that the OP meant plaster, rather than plasterboard.

 

[JohnD]

It's remarkably easy, and secure, to drill and plug a brick wall. I hope @noclueXD_ comes back for help.

Resin and threaded rod.

Nozzle

 

[Wayners]

Drill holes a bit bigger. 8mm ish
Buy ANY bolt resin. Cheapest one you can find. Shoot in holes the bolt resin. Buy some 4 mm threaded bar and cut to length and push in the resin. Give it a few hours to dry ( minimum 3)
Fill wall
Nut and washer to hold the radiator bracket on.

Re walls.

Single skin or cavity wall?

If single skin get some limelite plaster or other and make good. No PVA to be used.
