Review: It works well and is worth every penny - This stuff really works well. I did a couple of coats an still had a bunch left over. It really does help to lock in the foam. It dried very fast. I would 100% buy again but I won't have to because I still have a bunch. Great deal. Great heat retention. Easy to apply. Really toughens the foam, and it comes in a big bottle!

all good thanks

### ⭐⭐⭐⭐⭐ Easy to use and gets the job done
*by D***I on 24 April 2023*

I was able to apply most of it with a handheld trigger sprayer, although after a while it became more difficult to spray down the kaowool. For some reason the solution wasn't shooting out of the nozzle as it was at first. The trigger sprayer was still able to work with plain water so no doubt it was whatever is suspended in the collodiial solution that might have affected the sprayer. The solution gave the kaowool a somewhat solid surface. It's actually more like crusted toast. The rest of it is still a bit springy, but the refractory wool isn't intended to act as any kind of structure. Most important is that the surface isn't fluffy and loose.
