Which Silkaflex is best

Post by NORGIL on Fri Aug 19, 2016 5:18 pm

I need to seal around the trim strip between the monocoque luton and the cab roof of my Clubman, does anyone know which of the Silkaflex range would be the best to use ? It needs to be black. 

Surprisingly, I put Silkaflex into the site search and got no results !

512 is usually suggested for motorhomes and caravans.

Don't take my word for it though! smile!

That may be because the actual product is called Sikaflex - made by Sika AG.

IIRC at this point Dutto used to pop up and point to a page on Sika's website which gave a good summary of their products, but I think it moved and I don't know where it went...

I've just ordered some Sikaflex 512 from EBay Caravanworks £10.90 delivered to reseat our cycle carrier.

If you search for "Sikaflex" you get a few results.allthumbz

Thanks to those who corrected my error. Now I can search for it properly it seems that I am limited by colour. It seems that 512 is white and 221 is Black. Since I need the sealer to be black that somewhat narrows my choice.

You can get 521 in black which is a caravan, motorhome adhesive/sealent.

True Mike, and it doesn't show up so much as the white one on hands, ears, noses, trouser zips, what's inside the zip blushes  - and all the other places the damned stuff gets as if by magic.

Never known anything like it, and it's all but impossible to get off too! oh_blast!

Hope it did not seal your trouser zip up, Dave, that could have led you to a desperate situation!lol4

There's no black on ebay, checked the Sika website and it only lists 512 as white.

Cheers Mike. I was looking at 512 yours is 521. Very confusing and I'm still not sure which is best.  All I need it for is to form a waterproof seal around the trim strip it will not be taking any weight but does need to have a good degree of flex.

What I have gleaned from other posts that both 512 and 521 are both recommended for motorhomes/caravans for sealing and adhesive with 521 having the stronger adhesive properties. How they differ technically is above my head! But 521 is the only one of the two which is available in black.

And of course other makes might be just as suitable!!

I've just ordered several Sikaflex 221 tubes this week. Hoping that it is going to be suitable for renewing the gutter joint to my GRP hi top.
Very confusing to know what to use for the best.

Go on, go on, tell me Norman.........have you cut off the trim strip to repair the joint ? (and possibly re-spray that tiny strip)   Whistle1
If you have....how did it go ???
Thinking I may need to do this at some point in the future.... confused3    not looking forward to it though, as it doesn't look at all easy.   scratch head
Is there another option ?   think_smiley_46

Hi Logburner.

No I am afraid I lack the confidence to tackle the removal of the strip. I spoke to Mark at AS a while ago and he said there is no way short of cutting it off, so I am leaving it well alone (for now ). I have developed a water leak into the cab from somewhere at roof level, it drips down from behind the headlining onto the dash. It could be the windscreen rubber but that looks intact and in good condition. Without stripping out all the headlining which looks like it would be a nightmare I cant see where the water is coming in. There is some rusting and slight bubbling of the paint on the cab roof just under the black strip, I think there may be a pinhole (or worse) under the strip so the plan is to coat the area with rust inhibitor and seal all around the trim strip with Sikaflex which will prevent any water ingress. If that fails, then I will have to go the way of stripping the headlining etc maybe cutting the strip. 

Thanks to everyone for the Sikaflex posts.

Hi Norman,
Have I got this correct, your going to seal all along the strip, the gap between the coachbuilt bodywork and the joining strip that runs  around the top of the windscreen, with the reasoning that if the water cannot go there, it can't leak ?   scratch head
Seems a logical solution, more's the pity it wasn't built like that to start with.........would have saved a lot of hassle later on in its life.   hugegrins  (I'm assuming that this Sikaflex is somewhat flexible, as the name infers ? )

I had a tube of 221 delivered yesterday, and it has pictures of lorries and caravans which appear to indicate it's perfect for your sort of job.

It's polyurethane - so get it right first time!!! Once cured it's there forever, if not longer! timer

logburner, spot on, that's the idea. The strip needs to be sealed along the top, sides and bottom which should them make it totally water proof. 

Gromit's observation that once applied it's there for ever and a day is why I am seeking advice regarding exactly which product to use from the range.

Phone their technical helpline Norman.

When I was building cars using Sikaflex to hold them together (literally!!!) they were very helpful, and gave me loads of technical information.

I even understood some of it.

Dave smile!

P.S. If you can get at it, cheese wire is the best way to remove sikaflex. It still isn't easy, but with care you can shave off most of the residue left after cutting through with the wire.

Cheers Dave, I will give them a ring tomorrow.  The cheese wire is a 'grate' idea Grommit. Hopefully once I apply the Sikaflex I won't have to remove it though.

I know Dave, its a nightmare to get off of anything !  I have some  Car rear-light polyurethane sealant that has a dreadful smell that takes weeks to disperse. It got all over everything by the time I'd finished the job rolleyes
Good to hear that the 221 is good for the job. I got 2x 300ml tubes for a fiver which is a bit of a bargain. They have 9 months lifetime left
