Easy Application
Worked very well for me! Easy to apply.

It works
I sprayed a good amount of this with a little food coloring in it to see where it was then waited twenty four hours, it made a rigid coating on the surface of the material but it was still flexible then I put the refractory material over top.

It gets hard
Rigidizer did what it claimed to do, but didnโt go very far. I had to buy an additional bottle for a 2ft diameter x 2ft tall vessel, and still was shy. This can be DIYโed with clear kitty litter and sodium hydroxide (lye) for 1/10th the cost.

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!

Exactly as advertised
Dont water it down as much as they say too. Add a little bit of food colouring, it helps with application.

Skeptical
Was a little skeptical because it came clear instead of the other rigidizers that are blue. But worked well and cured up in a day
