Aqua-Flex - An Adhesive Sealant That Works Underwater

Author: Kurt harding   Date Posted:10 December 2016 

One of the applications we hear all the time is the need for an Adhesive Sealant that is able to work on wet areas. It makes sense when you think about it. Just the other day we had someone who had a leak on their patio guttering somewhere. Trouble is, the leak was only obvious when it rained and when it was raining you couldn’t seal it because you couldn’t get it dry.

For such situations, we would like to introduce Aqua-Flex Underwater Adhesive Sealant

As this video demonstrates, Aqua-Flex has no problems being applied and sticking to wet surfaces. In fact, it will even cure underwater.

Though it is relatively new to Australia, Aqua-Flex Underwater Adhesive Sealant has been used around the world for many years and is manufactured by a company in Germany called Weicon. We have this adhesive in stock now in 3 colours (white, black and grey) and, like all our products, can ship anywhere in the country. As the video hints at, you don’t need any special equipment to work with Aqua-Flex, a standard caulking gun will do the job.

This high quality adhesive sealant creates strong bonds and can be used indoors or outdoors thanks to its excellent UV resistance. It is not a silicone and contains zero solvents. It’s also really versatile and bonds well to metals, ceramics, wood, glass, stone and most plastics.

Because of this versatility and its ability to be used in wet or damp areas, the list of potential applications for Aqua-Flex is rather long. Just some of them are listed below…

Inside Sailboat Floor of Engine Room

Will Aquaflex adhere to wood to create a bond? We installed a bronze plate on the bottom of our boat while dry docked this winter. 4 screws hold it to a wood plate on the floor of our engine room. The hull, of course, is between the 2 plates. 3M 5200 was applied in all 4 screw holes according to the bronze plate manufacturer's instructions. Now that the boat is in the water, we have a small leak. We're thinking of filling the gaps between the wood plate and the floor of the boat with Aquaflex as that surface is now wet and the 3M 5200 can only be used on clean, dry surfaces. Is this a good application of your product?

Hi Mary, Thanks for contacting us. I think the aqua-flex would work pretty well in this application. Only thing I'd mention is that it will need to be exposed to air to cure so if the gaps are quite deep it might be best to apply it in sections (i.e. apply about an inch, let it cure, then apply more). If they're not too deep a single application should be fine. The wetness won't be an issue for this adhesive as it'll definitely handle wet surfaces and can even be applied underwater. Hope this helps. If you do have any further questions please don't hesitate to let us know.
