Resin alternative to shield anchor

[Martin754]

Hi there, hope you can help please.

Novice DIYer wanting to fix into brick that recommends shield anchors.

Never used shield anchors before & read they could crack the brick?

Would resin be a potential alternative please? Something like:

- Fischer FIS P Plus Polyester Hybrid Mortar Injection Resin
- Threaded bolts (concrete bolts?)
- Use a resin sleeve if hollow brick

I’ve read that cleaning the hole is fundamental when using resin.

I’ve also read that when using threaded bar (which I can’t), to twist it in so that the thread engages with the resin. Which I guess would also apply to a threaded bolt.

I understand that I can’t “tighten” the bolt in the normal sense, but was hoping this might provide a reliable fixing please?

It won’t be supporting a super heavy load, and it being permanent is fine.

Apologies if a silly question and a big thank you!!

Drill hole.
Blow dust out.
Squirt in bolt resin.
Push threaded bar in.
Wait a few hours although the one I used recently set in 15mins.

It's simple

You omitted the only important piece of information in your question, what are you trying to fix?

Hi Wayners, thanks

Hi foxhole, my apologies I should have said, it’s a wall bracket for fitness training.

I’ll be honest I don’t really know the difference between the different types of expansion bolts / anchors etc. Only ever used plugs & screws.

I didn’t want to crack a brick or end up with a hole too big, and resin sounds straightforward in principal.

I can find use cases for threaded bar, but not so much on just using threaded bolts instead.

Apologies again if this is a silly question and thanks again everyone

if you don't have any threaded bar, only bolts, cut the head of a bolt off and make that be the end you push into the resin

Or just buy some threaded bar; it's very cheap and likely supplied by the same place you get the resin

You don't have to fix things with the (often naff) fixings that are shipped with the thing

Decide how deep you want your hole to be by gauging how much of the threaded bar you want sticking out, and put some electrical tape or sharpie mark around the drill bit you make the hole with.
Make the hole as close to the centre of any bricks you drill. To clear dust out of the hole blow down a drinks straw inserted into the hole and a rag wrapped around the straw (but not so tightly against the wall that it forms a seal; you want dusty air to escape but not into your face).
Shut your eyes before you blow. slide the straw out as you blow. When using the resin don't fill the hole to the brim with it as it will splurge out when you put the bolt in. If you get it wrong (too little) you can add more resin
If using threaded bar you cut yourself consider using cap nuts to hide any sharp cut ends or cut the bar accurately so any sharp cut ends do not protrude from nut.

Re different types of bolt resin.

I've always bought the cheapest that will fit a standard mastic gun.
The styrene free hardly smells.
Some set faster than others.
Basically all the same stuff so whatever

As for cracking bricks, I've only done it when bolting into a hole too close to the edge on the end of a wall, and the hole was rather tight. I don't do that any more, and use the adhesive method to avoid expansive forces in such a position.

If the screw is horizontal, and the load is vertical, there is no pull-out force so you do not need to tighten with enormous strength.

Robin has it right, but I'd add, push the nozzle right to the end of the hole and withdraw it as you inject,so there is no air bubble trapped behind a plug of the resin.

Hi robinbanks, Wayners, JohnD

Thank you very much for your replies, feel more confident with it now.

Thanks again
