Everbuild Everflex AC50 Contract Acoustic Sealant and Adhesive, White, 380 ml

I had some hesitation because other reviewers said it didn't fit in a culking gun - they do in fact fit in a normal size skeleton/caulking gun. Someone else mentioned not getting nozzles, i got 3 nozzles with 3 tubes as expected. The sealant itself was easy to use when sealing round insulated plasterboard. I also used it as frame sealant around the window/plasterboard joints and round sill. Tooled off and cured really nicely. Between this sealant and insulated plasterboard the room is warmer and a little quieter. Will use again

A good item which did the job just what I expected.

Nice and fluid to use not too thick like others I have used

So I bought this with little expectations, as the gap around my window was minor so didn't expect much of a change.. after using it, it has changed the room. Quieter, warmer and sticks just like caulk, easy to use and can be painted over- worth every penny. Really good stuff!

Bought for sound and heat insulation around double glazed windows in central London. It seems to have worked really well and hopefully performance will continue to be good.You will have to use a normal sized caulking gun for this, and cut a hole atleast 5mm big as this is thick sealant and other people have reported the bases coming undone (didn't happen to me). Takes a while to dry which gives you a bit of time for smartening up and sorting out mistakes. This comes out a nice brilliant white and matched well with the colour of my windows.Highly recommended

This doesn't fit the standard size gun so be aware of that. I had to cut mine down to fit in my caulking gun.It adhered well and was easy to spread and fill the edges of the area I'm trying to reduce excess sound.It doesn't last very long and the nozzles it comes with seem to "waste" a large amount of filler in the tube.

Not as great as its states, settling time is too long in winter. I have applied day before and its still not set

Excellent product, does the job
