What sealant required removing Vision Plus aerial?

[Ingwe]

Finally getting round to removing the Vision Plus aerial. Have never used and planned to remove it and use the hole for fitting a wifi aerial and router. Have now decided that we manage well enough with the signal on our iphones and tethering to Firestick for TV viewing.

Removing the aerial pole will also free up some space in the wardrobe within which the Vision plus amplifier and pole are situated. We will keep power supply for the Vision Plus in case we change our minds about the wifi aerial. But the pole, a nuisance, will go.

I have a Vision Plus plastic blanking plate that is large enough to cover the hole and surrounds when the aerial and pole are removed. I’m anxious to avoid the hole leaking. I intend to remove all parts of the aerial on the roof, carefully scrape off the dried sealant etc and finally clean the whole area with white spirit or isopropyl alcohol.

Then I’m unsure of the best sealant to use to fix in place and water-proof the blanking plate. Also, the blanking plate has screw holes and I’m wondering whether I should screw the blanking plate in place (if the screws fit the old holes) or just fix the plate with adhesive/sealant and no screws. If new holes are required, I’d rather not screw the plate down. But if the existing holes work then it might be prudent to screw the blanking plate down and then seal everything.
Can I just use simple old sealant from B&Q (other stores are available) or is there a particular sealant/adhesive O should use.

Any other tips or suggestions most welcome. I realise I am an old fart and the job is a simple one for most of you but advice and reassurance always a comfort.

One of the Sika range such as 522 if they still do it or something similar, not from B &Q though.

Will have to check what sealant I used - it was a Sika something or other - will confirm which - but I did something similar to my PVC which had a very little used VisionPlus aerial. I used a solar inlet box to bring in a much smaller magnetic aerial and a shotgun cable from a 4G antenna. Biggest challenge was the gland for the shotgun cable and I ended up 3D printing something in TPU which is flexible. There was screw holes in my VP plate on the roof but nothing to match with them on my solar box so when I used the Sika I sat the toolbox on top of the van roof for 24hrs to hold everything until it had set. I speced the SIKA for the solar panel and had researched the correct type for that. I used what was left over for the solarbox - not being worried that there was going to be much physical forces exerted on it from the wind etc.

I fed the cables for the solar in on the other side(shortest route to battery and because the solar box was too wide for the ribs on the roof and because I'm pedantic I 3D printed an insert for the space between the ribs so that I could get better placement of the solar inlet on the roof and any pooling of water would have no effect. Please excuse my messy work with the Sika - it will win no prizes!!

I used Sika 522, as I already had it in for the reversing camera and solar panel mounting jobs. I decided it would be easiest to simply fit a flat plastic plate over the existing flat mounting plate - neat, and a good surface for adhesion etc. I may also route other cables through this in the future - TBC!

Have used Sikkaflex 291i for just about everything that needed sealing on the boat over the years both above and below the waterline.
Never had a failure. It's the Marine grade of their sealant/adhesives so heavy duty.

I took out an aircon unit that left a 400x400 hole and stuck some Ali sheet over it with this and have stuck everything else down using it before on my panels and skylights… lots of people on here use it…. Comes in white and black..

And quite a bit cheaper too!

Preparation is the key literally! No matter what product you use, adhesion to both sides of the mating surfaces is essential. An aerial through roof fixing will not be under the same pressure or stresses as a through hull fixing. A failure in a roof fixing means a drip of water, failure in a through hull fixing over time could result in a sinking!
So the vast majority of modern sealants will be fine but follow their preparation information to the letter.

My favorite too & 292i for heavy things.
But for this job a bit OTT as only fixing a plastic blanking plate.

As you are sticking plastic make sure its compatible not all Stka's so check the spec. I think CT1 would be good you can get it from Toolstagion.
