Perfect for the job, if a little pricey
Perfect for the job, although I wish it came it smaller sizes as I still have about 3/4 left and it's quite expensive.

Good
Did the job of sealing up gaps in my home. I coated it above wire mesh wool for extra peace of mind and so far so good..nothing has chewed through old entry points

Blocking Mouse entry
The product was delivered promptly. It is simple to use and (so far) effective. The metallic content should deter any nibbling.

Not dry after 9 days and is still soft
It’s been 9 days since I used this product and it’s still soft and wettish, I used it for indoors and not sure why it’s not 100% dry yet

Mouse Sealant Review (after first use)
I used mine in pantry to seal holes paired with metal mesh grid. You'll need a caulk gun and plastic glove or any tool to give a good finish, however is a bit fiddly compared to regular sealant. Has a distinct smell to it and it lingers for couple days Says takes 48 hours to dry - definitely not it been 4 days now and still not full dried. It works on wood and around pipes, good for big and small holes. It says it has metal fibres in it, having used it I am not sure from a visual look if it is there but from touch it has a sticky feel and feels very different to other sealants like ones used in bathrooms and roofs. Great for DIY work
