or i think sika bond is the one i actually got from B&Q

it cures in contact with moisture from the air, is that correct?
will it cure if its applied to something very wet?

my garage roof leaks very badly the felt is lifting, and over the years its had all sorts of crap thrown at it to try and hold it back a bit long. the roof will be replaced this year.

question is, if i sweep back any puddles, get it as dry as i can today, and squish most of a tube down, wil it cure enough to stop my car getting wet?

obviously the wood underneath is wet, but i'll stick a dehumidifyer inside to help, and i gess the rest will dry over time (its been leaking on and off for years) the wood will be replaced when the felt is done. its got a big dip (more like a step) in it where the puddle forms, so that needs sorted too

whats the thoughts?

blake this stuff works well and cures in wet conditions, - TEC7


TEC 7 linky

im sure it cures better in water as i once tried to keep an open tube fresh by putting it in a bucket full...

cheers Davy, where would i get it from though? ideally i need to do it today. its the 'warmest' (sort of lol) day we've had in ages. its about my best shot

Craig, thats not cool, but a good sign for me! so it still cured even when fully submerged? hmm, should work then. i've got nothing to lose after all... lol

Hi, heres what i did to stop my chassis getting wet
when i started building my chassis the condensation on the sheet roof dripped all over my shiny new metal so a quick locost fix was needed imediately so i used some left over some plastic membrane from B&Q and stretched it between the relevent joists and using wooden blocks (left over from chassis building) screwed it to the joists it catches the water and chassis stays dry
I know its a real bodge but it worked and was free
Ray

cheers ray, but i really need to stop the water getting in, rather than catching if after it has. its rain water, rather than condensation

heres the puddle that causes it

Description
you can see a past attempt to pour fastglas resin over middle of it, which worked for about 2 years, but has lifted now

you don't want to see what inside is like

hmm, doesn't look promising.. lol

B&Q did (hopefully still do) something like 'bitumen roofing tar' in a tube.

It sorted out the leak on my old dears garage roof, but going by the picture yours is a bit more serious

Didn't cost that much either iirc.

EDIT: spelling

i got impatient and didn't let the felt dry off... tried pushing the sika in the gaps and it just stuck to my gloves... oops

heres inside

if you can get it dry you can get pourable bitumen in a tub and stick a piece of felt on top if you cant get it dry then another thing is a tarp held down with bricks itll stop the direct rain but not the water from run off may help to dry out so you can do a temp fix as above or you need a roofers torch to carefully dry it once youve swept away the puddle
Ray

i think this sikabond will hold out most of it. we tried that paint on bitumen a few years back. it just peeled off you can see the remains of it in the first photo lol

Otherwise try


6 quid a pop and harmful to everything so must be good

Otherwise

£15



and a big 'old paintbrush

Personally I'd use the gunk in a tube until summer then strip it and do it properly. Although some people sneer at anything other than heat-gun bitumen you can get self-adhesive bitumen rolls now which are blooming good.

yeah, its only got to last a few more months til the good weathers here, or maybe a lot sooner if it doesn't get any better...

i mean fibreglassing the whole roof when its replaced. doing away with all the felt etc

flexacryl (or something) is a paint on sealant, but has fibres in it and lasts really well. NOTHING like the bitumen stuff, but about £20 for 2 1/2 litres. Good value though in my experience.....
