Sealants
Sealants
(OP)
Hi,
I have a problem trying to seal a 3mm gap between steelwork with a material that will keep out water - specifically rain water. The material will be at ambient but it may have to be applied in very damp/wet conditions and set to form a flexible membrane.
I am not a specialist in adhesives but I am looking into silicon sealants and caulking compounds and would be grateful if anyone has any suggestions about a suitable material and types of hand/auto applicators and any specialist tubing that can be added to reach those difficult areas!
Thanks
PJ

RE: Sealants
If you are forced to apply in wet conditions, look at urethane based sealants that REQUIRE the presence of moisture to cure.
RE: Sealants
If there wasn't a requirement for flexibility you could use an underwater epoxy.

It's very strong, will grip and cure on a wet surface, and will stay flexible in extreme conditions.
