Effective roof and chimney waterproofing requires proper surface preparation, including removing loose or damaged materials and cleaning the surface, followed by applying waterproof cement with fiber reinforcement in multiple layers to create a durable, watertight seal that prevents water infiltration and structural damage.

Big Progress on the Talasnal House!Added:
No wonder it's leaking state.
Well, it's no it's no wonder this has been leaking.
This is barely stuck and it's got it's down behind it. It's full of ants. It's not really doing anything comes off in big chunks.
It's um completely useless.
See how many ants there are?
Millions.
I'm going up my leg. This is just not even really stuck.
Look at the state of it. Just coming off in big chunks.
Wonder so much water's getting in there.
Hello and welcome back to Portugal Muse in central Portugal. We are back at the Talis Nal House today repairing some damage from the storms in February. Uh the main things we're hoping to get completed today is the chimney and the roof, making sure that they're watertight, that there's no leaks coming into the house and causing damage. And then the other big job that we're hoping to get finished today is another leak.
So there was water coming in from the public footpath and it was coming into that second bedroom and causing damage to the wooden mezzanine. Um so we're hoping to get both those jobs finished today. So, it's quite exciting and I hope you enjoy the progress.
>> Right. So, you know what to do and carry on with this.
Get all of that off. When you've done that, I'll come along with a mini grinder with a cut brush on it. Wire cut brush. Clean this off. If you can give it all a good sweep down, get rid of all the rubbish. Go all the way to the bottom. You won't have any problem cuz it's really soft and it's really easy.
It's not really [music] doing anything.
We've cleaned it up. We'll put one small fillet in to fill this gap up with the waterproof cement. Let that go off a bit and then put proper fillet along there.
I don't think it's worth keeping these bits of slate to put in it cuz I I think they're allowing water to get into the cement. Fill it. Let's >> have a look at one >> like that.
>> Cuz it was for decoration, wasn't it?
>> It's for decoration, but I think it's allowing it to expand.
>> Yeah, the water's getting in around them and allowing it to break.
>> And I'm what I'm going to do is put a fiber in as well to stop it cracking.
>> And the swimming pool waterproofer.
>> So that's not supposed to come off in one piece like that.
>> Oh god, no. That's supposed to be properly stuck on here.
>> Cuz that's >> that's useless. Look how soft that is.
It's completely useless.
>> So that won't have had any um like waterproofing in it either.
>> No, that's not waterproof at all. It's not stuck at all.
>> Maybe this was.
>> No, >> that's just a bit of um stuff painted over it.
>> Okay. So, if I just remove it >> and then we need to get it as clean as possible.
And then what I'll do, I'll dampen it as I'm going to allow it to bond properly.
And I'll put some cement with fiber and waterproof.
do a thin one first just to fill in all the holes so you can work it right in and then we'll put like a bigger one going over the top.
>> That's the way we're going to have to do it.
>> Okay.
>> All right. Are you all right carrying on with this?
>> Yep.
>> Okay.
[snorts] >> [sighs] >> seems right.
>> Safe. What are you attaching it to?
>> Sky hanging it up like that.
>> You got it like this.
>> Yeah. Your mate up there. He'll hold on to the other end.
>> Just tie it on the scaffold on the chimney.
>> It's only to stop you hitting the floor.
Chimney. Yeah.
>> Don't matter if you fall as long as you don't hit the floor.
>> Chimney.
>> It might fall over. I'm more thinking more of a scaffold.
>> Right. It's a long rope. We'll see what I can do.
>> Anyway, >> you look like you're going to go skydiving.
Hey, [snorts] how's it going? [sighs] >> I'm really sweating.
>> Don't need to wearing black. I think >> I look slightly slimmer in black. So, you don't need to look slimmer.
Anyway, >> yeah, >> I think I figured out what's going on with the different layers here, right?
>> Um, there's the big bit that comes off like on its own pretty much. And then they they've used something else, >> which is like a purpley color.
>> So, that's attached to like the shish stones. So, I'm really delicately and carefully trying to take that off [snorts] >> because that needs to come off for the new stuff to adhere. Right.
>> That's all cracked and loose.
>> Yeah. So, that's what I'm doing. That's why it's taking so long. I bet you were thinking, why is it taking us so long?
>> I thought that would take ages to get all that off.
>> I haven't finished.
>> I'm just having a break.
>> This is really hot and everything's burning your hands to touch.
>> [snorts] [gasps] >> Hy. Ah, [sighs] I didn't bring a brush up. I really need a brush.
>> Yeah, >> that blue one.
>> Yeah, any of them. I think there's a couple down there.
>> I had fine.
>> Yeah. All right.
No, not from there. Can you You might have to bring it up. Um, >> if I go into the bedroom window, >> I'll come down the ladder. Can you give me my blue hammer as well? Bluehandled hammer out the bucket. I'll come halfway down the ladder and take it.
[snorts] >> Am I going to the bedroom or here?
>> Bedroom. Okay, it's >> just I've tied myself on and it's literally just tied myself on just now.
That is the problem with not having a another carabiner. It's such a bull undoing and doing up. Thank you.
>> [snorts] [snorts] >> Mhm.
Mhm.
>> [snorts] [sighs] [snorts] [snorts] >> Yeah.
That went quite well.
Paper wasps, my mortal enemy.
Right.
So, we're felted all the way around the chimney now. back gutter up the side on the end of the um the corrugated sheeting that's under the unders and overs.
Um now I'm going to put some cement around there, some waterproof cement with some fibers in uh just around the chimney.
Nice little fillet and then tile it back in.
>> Am I taking it far enough?
>> Yeah.
>> Yeah.
>> Yeah.
>> And then obviously The bedroom finishes here >> and there. You can see the really bad bits, can't you?
>> So, there's a light skim of it just here.
>> I wouldn't worry about that.
>> But would that be going in the woods or not? Really?
>> There's no sign of it.
>> No, >> just stop here. Yeah.
And we just got to give it a good clean up.
He's probably going to turn left and go out that hole.
Oh, no. There he goes.
So, all I'm doing now is just giving this a really good clean up. So, uh it gives a good key for the cement which [snorts] is a mix of um sand and cement waterproofer that you use for making swimming pool cement and fibers that will stop it cracking. [snorts] Um do it in two layers. first one just to fill in all the holes and cracks and then uh tomorrow we'll give it like make a proper cement fill it here that will be waterproof and well bonded to the wall. But I need to get all the moss and all the old dirt and everything off first.
Right.
>> [laughter] [snorts] >> How you getting on?
Well, as you know, I was I put another um layer on the top to protect the first layer. So, the first layer is the one that's really going to seal it against the wall. And then this is on the top just to build it out a bit, give it a bit more protection. I wasn't going to put these pieces of slate in because on the last one, that's where it was breaking up around the edges of the slates. But, as this is more decorative, I think it looks a bit nicer with the pieces of slate put back in. But, I really need this cement to be going off a bit quicker. We're at the end of the day almost. Um, it's still really soft and I still need to finish it and smooth it and I need to get it done because we got thunderstorms forecast for tomorrow on Saturday. I'll try my best and see and see if I can get it finished.
I finished um sealing around the chimney, replacing the broken tiles behind it. Um, I'll show you what I've been what I've been doing.
So, as I told you before, these are unders and overs. Um, well, just the overs on top of uh terracotta colored corrugated sheeting. So, without removing that sheeting, which would have meant taking all of this whole section of roof off. Um, you know, there was no way of replacing the metal flashing around the chimney, which was um which was no good. So what I've done, I've used flat roofing felt torch to torch on flat roofing felt over the top of that up both sides and behind in the back gutter and in the gap at the end where there where the sheeting finished short of the end. And then I've tried to um color it with some roofing paint over the top and I've replaced all of the broken tiles around the chimney and there's new cement at the sides.
It's really difficult to waterproof these uh shist chimneys because, you know, the water can get in these little gaps and then run down the back of it. But I've gone in as far as I can with a pointing at the bottom and at the sides.
So, I'm pretty confident that'll be waterproof now.
And I've replaced the broken tiles along the rest of the roof. These stones and bits of slate that are on the roof, what they're there for is to prevent wind lift lifting the tiles up. The bottom course is bedded on cement.
Then they're just held on hooks. They just sit there on their own weight.
Normally when it's when you have the unders as well, they fit together better. But when you're doing it like this, you need hooks to hold the the line of tiles in place. And then these big lumps of heavy slate on the top. Um, they're there to stop the wind lifting the tiles up, but it'll be all good now.
No more water dripping through the house.
What a view. It's really hot day again today.
Well, we managed to get done what we wanted to get done today, which was to finish fixing the leaks on the roof and to finish fixing the leak where the path meets the side of the house cuz all the water was coming in through the wall there. We were up against it a bit on time because we're waiting for the cement to go off uh so that we could, you know, we could finish it. Um, we've just about managed to get it done. It's just about managed to set enough. Uh, we're right at the end of the day now.
So, I'm glad we've got that done. It's very important to get all the leaks fixed before you move on to doing any other work because, you know, you need to we need to be fixing the damage and we don't want more damage to be caused if we get any big raintorms which seem to come out of the blue. Um, so now we can get on with sanding back the floorboards inside. um retreating those, replacing anything that's rotten, and then we can start making the place look pretty, ready for guests in the summer.
So, uh there's quite a lot to do still, but the important stuff has all been done now. So, thanks for watching. Um hope you've enjoyed this video, and if you have, then please subscribe, uh like, comment, share with your friends, hit the notification bell so you don't miss any videos, and see you again soon.
Okay, bye.
