Fixing through tiles.
A fixing into a plastered brick wall through tiles.
Most of the fixings went well - wall plugs pushed through the tiles into the brick. But one obviously hit the soft old mortar, and won't tighten. Anything that could be squirted through the hole to give a decent fixing? Or any other ideas? I'm already at the limit of the longest screws I can find in that diameter. -- *Yes, I am an agent of Satan, but my duties are largely ceremonial Dave Plowman London SW To e-mail, change noise into sound. |

It depends a bit on whether you have a blind hole or whether you have gone into a void of any significant size. Polyester resin is one of the classic "fixes" for this sort of problem, but perhaps a bit expensive for just the one, and a small hole. Also, how strong does the fixing have to be? If probing suggests you have a reasonably small blind hole, it's just that the plastic plug is spinning, then one strategy would be to inject a surplus of epoxy glue, then push in the plug and wait for it all to set. Make sure the plug is all the way through the tile. If the void is larger but still fillable could you inject in mixed up car body filler to fill it completely? Forget the wall plug, just drill a pilot hole and let the screw grip on the filler. |

My worry about simply filling the void is that the load will be taken by the tile - unless it bonds well to the brick. As the plaster ain't up to taking much load. If the plaster is anything like mine (10mm+ thick) and a sandy type mix squirt some 50:50 water:PVA mix into the hole and let it dry. Then do a filler of your choice. This will stabilise the plaster around the hole and make it less likely to crumble. As has been mentioned before there are different types of wall plugs and if you have been using the standard brown/red/blue/yellow type then a different type of plug may work better if the inside of the hole has been stabilised with PVA. These days I prefer this type https://www.toolstation.com/fischer-...ce-plug/p98292 The kind of rigid tube you need to go down the hole is the kind found on (disposable) pump action soap dispensers that you may have in your bathroom, wash-room, or next to the kitchen sink. The tube should just pull out of the pump head. Choose a soap dispenser with a fairly thick soap as the tube is likely to have a larger inside bore.One I'm just to put in the recycle sack is 5mm inside diameter and not bendy. https://tinyurl.com/y5yb85nj Ive just tried the fit with two ink refill type syringes that I have. It is a loose fit on a 30ml syringe and too small to fit over the outlet of a 100ml syringe. Just a random thought: with a suitable tube you could fill it with a substance of your choice and use the back end of a suitably sized drill bit as the plunger to push out the contents -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

If you have a large syringe a two part epoxy would do it. I should warm it a bit first so it's runny, and be prepared to squirt in a lot more than you'd think. As preparation you could drill through the hole slightly diagonally to make a bigger cavity. You could enlarge the hole through the tile with a little round file if necessary. Put gaffer tape over the hole to keep the resin in. Bill |

Anything that could be squirted through the hole to give a decent fixing? Or any other ideas? I'm already at the limit of the longest screws I can find in that diameter. My solution to this type of problem would be to first remove the plug, then get a syringe (without needle - the type used for filling ink cartridges) and force clean water into the hole. Mix some filler and after again wetting down the inside of the hole force the filler into the hole using the back end of the drill bit to pack it to the back of the hole. If you don't wet the hole sufficiently the water in the filler will be immediately sucked out by the dry brickwork and become somewhat ineffective. Either allow the filler to dry and re-drill for the plug or whilst still wet re-drill very slowly by hand to the exact depth of the plug and insert the plug. Allow everything to dry before inserting the screw. A sloppy gritty sand cement mix often works better than a smooth filler. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

How strong a fixing do you need? If it's a relatively light load, you may get away with one of those grey universal plugs which you can use in either brick or plasterboard. If it's a good fit in the tile (don't push it right through) the tile may be able to support the load. -- Cheers, Roger ____________ Please reply to Newsgroup.

Apply some grease to the thread of 'your longest screw', then mix some Plastic Padding car body filler and quickly before it sets and using a syringe, squirt it deeply into the hole. Push it in as full as you can get it, then put the screw in, but not all the way. Later, once it has set, you can tighten the greased screw. |
