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

Great sealant

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

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.

Does exactly the job it was intended to do. Tube is actually longer that standard tube but it should fit any standard gun fine.

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!

Now my windows are quiet and less drafty

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

seems to have done the job well, and is effective to seal the gaps around some sound insulated plasterboards. But if you cut the nozzle too little the pressure seems to be too much for the base of the container and it fails (I had left approximately 2mm opening). Decent amount of sealant oozed out of the bottom and had to be applied directly with a knife. On the second container I had slightly larger gaps to fill so I cut the nozzle a bit wider (about 4mm opening) and it was fine.
