Roof Strap Whats The Best Method To Do A Reseal ?

Recommended Posts

I am wondering whats the best method to take these alloy strips off that makes the join to the rear of the caravan, after looking at the rear corner its a few inches inside rear corner i am getting damp readings just above the join so i was wondering if anyone as done this job by removing and replacing the alloy strip . .

 

my question

what will i need to complete this job successfully i mean its only a alloy strip with what looks like mastic about 20 screws holding it in place with some kind of mastic on which looks quite wide .

 

would it be best to use a

Sikaflex sealant theirs a few types of this stuff and its about £10 each or should I use the stuff that comes on a roll .

 

any suggestions or help would be great .

Remove all the screws, carefully prise the roof strap away from the van, clean ALL the old mastic off both strap and van.

 

Use Soudall Fixall and put a good bead along the strap so that when screwed down the mastic will squeeze out along the edges. DO NOT scrimp on mastic.

 

Refix strap with stainless steel screws and cover each screw head with mastic.

 

Make sure you have a really good seal at the ends and over the join of the back panel to roof .

 

Carefully tool the excess mastic along the edges to give a smooth finish.

That is NOT a good item to use on a caravan.

 

Use the correct items.

 

Soudall Fixall is better and easier to finish than Sikaflex .

Looks can be deceptive!!!!

 

For a start it only comes in 3 colours, grey, anthracite and black.

That will not look very good on a white caravan !!!

 

Secondly it stays sticky,so collects all kinds of road dust, grit, leaves, etc . ..looks great, ,NOT.

I had a workshop do mine, I thought £90 was quite reasonable. You've got to be really careful to prep the surfaces correctly out will look ok but still let water seap in after a short time, as it was quite a critical repair I thought it was better off in the hands of the professionals.

Please take Brecons advice, he's in the trade and knows what he's talking about. If the other stuff was better it would be in use by the trade, because it's not, what does that tell you?

Take the good advice, not adverts claims. ........Peter

Soudal Fixall is super stuff. It will do what you want it to. I would apply a blob to each screw as you refit the strap so that the sealant seals the screw in to prevent ingress of water + as others have said apply some to head of screw and smooth over. It also contains a fungicide so no mould growth on the sealant. Do have a look at the You Tube videos for this product - sold it to me and I have used it for a couple of years now with great success.

It is a caravan product Brecon. ...widely used on European caravans & motorhomes & is far superior, easier to use & more expensive than soudal products.

. ...it's also supplied in many different colours & formulations for different interior & exterior applications.
