Use with caution

Amazing stuff 👏 however when travelling make sure this is in a secure place. I purchased this and placed on the back of my car seat (god know why), after breaking because drivers in Hull like to test their breaks regularly whilst driving 40mph, the can hit the back seat and of course yes you guessed it ppffttttttsshhhhh the expanding foam had decided to settle between both my seat and passage seat. This marshmallow type substance was not going anywhere until it had dried. 24hours later I had 2 of my very own bespoke booster car seats. Needless to say i could not use them as they sadly would not have passed safety laws. The other tin however is keeping my house really warm and fixing the shoddy workmanship conducted by Hull City Council. I would purchase again if I needed to.

Worked fine

Used this for filling gap where, last year, wasps made a nest in the loft. Worked ok, but oh very messy. Glad I used all the proper precautions.

This fills the gap

Had some sizeable gaps to fill - had not used this product before. Easy to use and did the job. Very happy.

False advertising

Works, expanding to 40 times the size of the can is an absolute lie, more like 4 or 5 times

Does the job but difficult to stop is spilling out

Blocked up the holes in the floor and haven’t seen any more slugs since! Good! But, when using there is a lot of excess foam which seeps into the nozzle. Make sure you have some kitchen role and thoroughly squeeze it out otherwise it gets everywhere!

Fills gaps, make sure you where gloves. Gets messy
