Making good a wall following aerial cable entry

[KarenCC]

Hello all

I had a new TV aerial run through an external wall to my kitchen. However, the external brick work was damaged slightly during the work - a small amount of brick fell away near the hole. Also, the 'finish' is not that great - just a (small) hole and cable coming through. The company said they normally go through the skirting board these days so they didn't have any proper aerial socket boxes etc.

I have three questions if anyone can advise please?

a) Is there a recommended glue for sticking the exterior brick work back on or is it better to just use some sort of filler to patch it up? (the piece of brick is about 2 inches wide by 1/2 inch deep - is intact and painted)

b) I'm looking at putting some sort of cover/skirt around the entry/exit holes for the cable, just to smarten it up a bit. I've been looking at this sort of thing: https://www.screwfix.com/p/labgear-whit ... pack/33725 - my questions are - is it best to have these on the inside and outside of the wall? And does anybody know of any that can be added without having take the end of the aerial to thread it through, please? I'd thought of using a Stanley knife to cut it down one side and snap it on but the plastic looks a little hard for that.

c) Once I've done all of this - I do need to repaint the back wall as it is looking a bit scuffed up. Before doing so, I'd like to apply some sort of damp protection around an external tap/gutter (there are no obvious signs of damp on the inside of the kitchen but I've noticed the wall is getting black patches on the outside near the gutter/taps, where there isn't much sun). My question here is - is there something I can use ON TOP of the existing paint work, before painting over it, to protect water damage... I've looked up various 'Ronseal' products but am a bit confused by which would be most suitable.

Many thanks for any pointers if someone has done this before - it would save me time botching the job and having to restart...

Kindest as always.

I'm not too sure on C) but for
A) to be honest gluing a piece if brick back on is not likely, I'd use an exterior cable entry cover such as
https://www.screwfix.com/p/labgear-bric ... pack/58284 to tidy the area and cover the blown brickwork.
if the coax runs down the wall, Idealy you want a bit of slack in the cable so it loops down and back up into the entry hole, this will prevent rain water tracking down the coax and into the entry hole (when the water gets to the bottom of the loop it will drip off and not climb up the cable.)

B) those covers are internal covers (though I guess can be used externally, but I've not come across any that are split and ideally will have had the coax ran through them before the coax was terminated with a plug that connects to an appliance.

In (A) I would use an epoxy resin glue to stick the broken brick piece back. Like thihttps://www.screwfix.com/p/araldite-2-part-epox ... 5ml/2457hs

In (B) Would these work https://www.diy.com/departments/qty-2-w ... 859_BQ.prd

In (C) Stabilising solution is a primer/sealer with the added quality of binding to chalking or friable surfaces and making them less water-absorbent. It is highly penetrative, meaning it will help fill up any holes in porous surfaces, allowing you to apply a paint system without any issues. You can get it in various volumes to suit your job.

B should be https://www.screwfix.com/p/araldite-2-p ... 15ml/2457h

Hello DWD

Just revisiting this bit of your advice...re treating a wall to resist damp...

What is the brand of stabilising solution please? I've attached a photo of the wall I would like to put it on... before I repaint.

Kind regards

as an aside
If your cable doesn't have a down loop to shed water then 2.3mm thick string looped round with a small knot or 3-5mm tail to shed the drips

virtually anything will work providing its say at least 6mm from the entry and at least 45 degrees sloping away from the wall

Thank you for that advice.... I'll try it. I've found something for the inside though unfortunately the tv guy didn't put the cable at a 45 degree angle. But I can probably feed some cable through...

This Sandtex one is a well known make https://www.toolstation.com/search?q=st ... g+solution that should seal it for your masonary paint over. I suggest using Sandtex see https://www.sandtexpaints.com/uk/masonry-paint/ but shop around.
