Rated 5 out of 5 by Perfect for the job Bought this product to help insulate my garage filled all the gaps very well where i had put up boarding .I was amazed by how much the foam expand,s only takes about 30 mins to dry then can be painted or sanded . A very good product but just take care how much you use at a time as it is very messy to have to clean up overspill . 06 May 2016
Rated 1 out of 5 by Overpriced and poor quality Cost considerably more than the equivalent product from builder's merchant and the very flimsy nozzle snapped almost as soon as I used it. End result was having to get the foam out by pressing a nail into the top of the can. NOT what you want when you are sitting on the roof! 13 April 2016
Rated 1 out of 5 by Rubbish This by far the worst product of this type that I have come across. The foam valve and trigger look the same as other manufacturers but the dispensing rate is so slow that the valve soon clogs up. That apart, the worst aspect is the very poor quality foam. On curing, it quickly becomes obvious that this is a very low density foam and so cannot be relied upon for a strong durable bond and the foam cannot easily be finished (e.g. smoothed/sanded). If all you want to do is fill a simple to get at hole/gap and you are not concerned about the finish then this may do the trick for you. Otherwise, buy Unibond. 24 June 2013
Rated 4 out of 5 by "Sticky stuff" The foam worked as expected. I used the foam to fill in gaps in my floor board. You don't need to much to fill in any gaps. Pull hard on the trigger to fill a bigger hole. I replaced a disc of plasterboard back in the ceiling and used polyfilla expanding foam to hold it in place, this it did very well. Problem when you get the Foam on your hands it took days to get off. I know that you are supposed to use the gloves but these tore and I could not get this stuff of my hands.I was told by friends do not wet your hands it makes it worse, I have been told there is a substance used for spraying on car electrics and lubricating nuts and bolts. This is supposed to be good at removing the sticky foam. 16 January 2013
