If not, what would be the righy solution?** A: Not sure what the depth of your hole is or where it is. That size would have to be done in stages if just using this and it takes a few days to dry. Wire mesh - available on Amazon might be easier in combination with this? **Q: How thick is this sealant i.e. how small can I cut the nozzle hole to? I have a fiddly job and need to add a length of tube** A: It isn’t that thick so you can cut the tube quite small. Takes longer but you can always increase the size. **Q: Does this contain rat Poison?** A: No. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, stays soft *by I***S on 23 June 2026* This works well.
