Weicon Aqua-Flex Underwater Sealant and Adhesive is a special type of adhesive designed specifically for wet or moist surfaces. In fact, it can even be used underwater. Aqua-Flex can be used as either and adhesive or sealant and remains permanently elastic after curing. It also has good UV and weathering resistance which allows it to be used indoors or outdoors.

Weicon Aqua-Flex Underwater Sealant and Adhesive is 100% silicone-free and contains no solvents, halogens or isocyanate. It withstands attack from fresh and salt water (and other media) and bonds well to a range of wet or damp surfaces including metals, many plastics, ceramic, wood, glass, stone, aluminium and stainless steel. Weicon Aqua-Flex has also been certified by ISEGA as an adhesive for use in food technologies.

Will this stick to sandstone?

Yes. Weicon Aqua-Flex bonds very well to sandstone and other forms or masonry, concrete, bricks and porous surfaces.

Can I use this outdoors?

Definitely. Weicon Aqua-Flex has excellent resistance to UV and very good ageing stability so it will not go brittle or loose it’s adhesive strength.

Is this a silicone?

No. Weicon Aqua-Flex is an MS polymer based elastic adhesive. It contains no silicone, isocyanate, halogens or solvents and will not attack sensitive surfaces the way some silicones (particularly acetic cure) can.
