Sealant ooze

[Emmit]

Morning all,

Wonder if anyone can comment on the enclosed photo's.

When we picked up our van last December, the seals around the vehicle were immaculate but, over the Spring a white 'gunk' oozed out.
It is sticky and unsightly and remains sticky to the touch regardless of the length of time exposed.

I removed it about thrre weeks ago but, as can be seen in the attached, they are reappearing.

Suggestions please.

We've got the same on our 2020 van. Except ours is mostly black ooze.

we have similar decided to live with it

We too have a Burstner, same colour. Ours is 5 years old and still oozing, especially in hot weather. They use non setting sealant. I think the lager oozes could be carefully removed, as for the rest live with it.

I had similar on my old coachbuilt around main skylight. It really doesn't set and can dribble very very slowly so worth tidying up ..

But surely if you keep removing the excess there will come a time when there is no sealant left in the joint to do the job? I’m really surprised to hear of this to this extent, 5 years!

Yeah. Our Carado oozes black sealant that never sets and is a bugger to get off. I guess its an excess and when its cool some will be drawn back in so be careful about removing too much

Its the modern way it seems

Same for us too.

If it's coming out for years maybe the joint is emptying down from the top.

Reminds me of glass that is hundreds of years old, I read it's thicker at the bottom because it never fully sets.. Don't know whether I believe that mind

Best not to. That's an urban myth. Before float glass was invented, they used to spin out discs of blown glass and then cut them into squares. The glass closer to the centre is thicker than the glass at the edges, so the glass squares have a variable thickness and were always installed with the thickest part pointing downwards. The centre bullseye where the blowing was done from wasn't wasted and was often used in the centre pane of cottage windows as a point of interest, or sometimes even used throughout a window, as it was the cheapest pane and expensive houses would have refused them.

We always get a tiny bit around the windows on the Hymers we have had but I've never seen it as bad as in your photos, I would say that is excessive.
