Works as advertised.
Works as stated in the description. I did a double saturation and it really firmed up the insulation very nicely. I would recommend this size for more than one small project and to maintain the rigidness of my original forge after several uses.

Arrived Quickly, Easy to Apply
I used it to render some old mineral insulation change from being dried out and crumbling to much harder and solid feeling. Make sure that you wear protective gloves because the silicate will severely dry out skin and irritate like the container says,.. much like cement does.It was very satisfying to see the covering set up firmly within 12 to 24 hours. (It sets faster if it is heated,. which of course a furnace does do. ;-) )

Worked very well and was easy to apply.
I bought this to spray the inside of new smelter I cleaned out an old eyeglass cleaner bottle and used it to apply the product. The product worked fantastic and was dry within a day.

It gets hard
Rigidizer did what it claimed to do, but didn’t 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 DIY’ed with clear kitty litter and sodium hydroxide (lye) for 1/10th the cost.

Hardened the Kaowool like a charm. With plenty left over for a side project
It worked like it was supposed to. Harding the Kaowool before i put on the refractory cement. Plenty in the bottle! Just stayed it on let the puddles seep down. Then the sides and top! Well see how it work's going full blast soon!
