    Would this duct seal be suitable to seal around a mains electricity cable which is underground in a duct? If not do you do something similar or can you recommend something? Answer:
    If the application is in an area where freezing/thawing can occur in the ground or is exposed directly to soil then a silicone or polyurethane sealant would be better suited for the application.

    Could I use this product to seal a 2cm conduit in a water feature. We have a cable running through, for a fountain which is allowing water to pass. Thanks Answer:
    31-605 Duct Seal is to seal ducting or conduit against moisture, dust and gas, but is not intended to be immersed directly in water. However, if the application will not be in the water, it should be OK as long as it will not be exposed the freezing/thawing. For these applications silcone or polyurethane sealants would be more suitable.

    How much of the duct seal would be required to seal a 150mm duct with two cables installed? Answer:
    You would need 14.7lbs of duct seal for every 231 cubic inches of space to be filled. A round duct (150mm in diameter) filled with 2" (50.8mm) of duct seal, would require about 3.5lbs of duct seal at an estimate. You should plan on 5lbs of duct seal to be sure.

    Could this putty be used the same as ballistic putty, which is used for a pellet trap for air rifle targets? From what I’ve been told it is exactly the same. Thank you. Answer:
    We have not done any testing to affirm this, but we do know of other customers using this for that purpose (ballistic putty for pellet guns). It actually does make sense, but again, we don’t have any test data to affirm this, regarding the stopping ability of the putty.
