Hold tight, and welcome to today’s video. My name’s James. Today, we’re gonna look at the murky, misty, dark world of sealing up shower trays. How to seal ’round tray, and how to seal up.
Now luckily we’ve got an old job here where we’re ripping out the old silicone and all that. So we’re gonna show you quickly how to do that. I’m not going to use the traditional, old removal tools because frankly, I think they’re useless. I most prefer to use my little scalpel and a couple of other little bits I always take with me and my silicone removing tools box. Anyway, I hope you love today’s video. You got any problems you all want to know, then let us know in the comment section below and as ever, share this video. Remember everyone, hold tight.
If we look closely at the current silicone situation in the shower, you can see it’s been in for a while. So you have a quick learn, now what I’m gonna do firstly is remove the old silicone. I’ll just show you how to do that and I’ll warm out the shower and then I’ll get on to do it all by myself quickly. You don’t want to watch me do all of that, so let’s have a closer look.
So I’ve got quite a few little tools that I use. I mean, I love using my little window scalpel. That’s brilliant, you can really shove that into the gaps and try and get stuff out and like that. I even use my floor board jammy. These are actually used mainly to get the nails out of floorboards when you go to put them up. Because it’s got this angled flange on there, I often like to work along with that. That’s great because it doesn’t leave scratch marks. Or even use some type of small ruler. The thing is, I don’t tend to use the special tools
that come with it ’cause I’ve just found, over the years, that I can get a better finish using the tools I’ve got here. So first up, I will use these tools to actually remove any of the main parts of silicone on here. Try and get the silicone off the tallows and off the bottom of the shower tray. And obviously, all out the corners as well. Just get everything removed, and then once we’ve got all our silicone out of the way, I’ll use a little bit of CT1’s Multisolve. Which is quite good, that can get rid of any residue parts of silicone. And then give that a good rub down with a bit of paper towel.
So there’s loads of different silicone removers you can use, but they’re only really used for after you remove the main body of silicone. I find that loosens up the little bits that left. So once you’ve got a fairly clean park, I often recommend you come here with a small hoover. Hoover out all the bits of silicone you’ve got ’cause they might get in the way when it comes to putting the new silicone on. And once you’ve done that, you’re ready to add your new silicone base. So let’s do that now.
Alright, so now we’ve pulled out all the old silicone. We can get our silicone gun and run our new beam nice and lightly just along here, like so. Then, I just chose my profile I’ve got here. And I’m gonna use a nice, thick, 10 mil profile on this, that’d be lovely on this. Then you run that along there like that. But we don’t use our fingers because if we use our fingers, you get bacteria into this and it will actually allow it to mould earlier on in its lifetime. So, we just have this here, nice roll of blue roll, and go along it just like this. Beautiful. Carry on doing that all ’round the shower tray bottom and up the sides. Making sure that you do a nice, neat bead and making sure that you clean up regularly kinda every six inches as you go along.
As soon as you’re done, try and back out of the shower tray without touching any of your silicone and leave it for 24 hours to set. Alright then, so there we go, all done. As you can see, that video hopefully helped you out when it came to cutting out your old silicone, getting all cleaned out and everything, giving you an idea of some sorts of tools you need. As you can probably see there, the window scraper is, by far, the best tool for getting old silicone off.
If you cut the top, then cut the bottom, then pull once cutting the top again, that will come out as easy as you like.
