Could this be the answer to leaks?

I imagine all of us have seen the adverts to prevent senitive teeth. It suggests that the toothpaste penetrates the micro holes in yhe teeth enamel and seals them off thus stopping the cold tingle.

Imagine this on a large scale. If there was a sealer that would penetrate the minute gaps which allow water ingress and causes capillary action and leaks/damp caravan.

Well I think there might already be a product out there which will do the job.

Some while ago I had a leaking shower which was proving impossible to stop. That is until my plumber pal came along and recommended a penetrating grout sealer. This is what it actually does and I have lifted the text from a website.

"Penetrating Sealers: Penetrating sealers soak into the microscopic voids of the grout. Typically made of silicone or latex solids suspended in a water or mineral spirits base, after application, the base evaporates, leaving the solid material within the grout. The material fills pores and capillaries close to the grout surface and in so doing, reduces the absorption of potentially staining compounds."

The product recommended is Aquamix.

After nearly a year now my shower has never leaked and recent inspection under the tray it is as dry as a bone.

My thoughts are that the shower has similar sealing around the tray to a caravan roof. Is constantly bombarded with HOT water and is probably under more severe conditions than a caravan roof. The dealer also offers the additional mould inhibitor as a bonus.

So when the weather improves and I can get to clean the van I'm going to bite the bullet and give the roof joints a coat of sealer.

By the way I have a Bailey Ranger 470/4 which seems to be the worst but so far no leaks and it's out of warranty.

Fingers crossed.

Hi Michael

Interesting!

I didn't realise that "any" hole/aperture in the van was a potential leak point. I had assumed it was the roof only.

yes there is a word for it that escapes me at the moment,where any hole left by a screw can suck water into itself depending on the conditions of the day.ie warm or cold outside.

I know what you mean.

This was the problem with my shower. There were no visible signs of a leak and silicon sealant proved ineffective. The water that was coming through was quite incredible, it seemed that once water found a passage then it was actually siphoning itself through.

I imagine the sealer takes advantage of this phenomenon.

I think the word (or phrase)is Capilliary action. Its the process where liquids are drawn into very small holes or gaps.

The sealant idea sounds a good one, but is is going to be flexible and resistant to the destructive effects of UV?
