Rutland High Temperature Adhesive, USA-Made 128 Oz Sodium Silicate 40% Solution, 2000F Heat Rated, Water Glass Cement Floor Sealer Against Oils, 1 Gallon

Products great but sometimes it is shipped incorrectly and leaks a little, lucky it was wrapped in plastic but not 100% sealed off, So it did get on some of the products it shipped with, fortunately the other products had been in sealed bags and I could just rinse them off.

Great product, always works well and is consistent. Used to get at Home Depot but my local store no longer carries it. This showed up with no protection in the box other that a bag around the jug which was leaking badly. 5 stars because the product is great, wish I could give another score for packaging.

I use this product to adhere rocks to blocks of wood so I can run the rocks through a lapidary saw. I cut a flat face on one edge of the rock, then "glue" it using water glass to a piece of 2x4, and the 2x4 can then be held securely in the saw's vice. I've glued up fairly large rocks this way, and they have held well. These are cut on oil saws, and the oil doesn't interact with the water glass. When done, I toss the end piece with board into a bucket of water, and in a few days it will dissolve the sodium silicate so the board pops right off.

this product was just what I expected and worked well for what I used it for which was cement for making a small forge. the packing was horrible though basically it was a gallon container of liquid put in a box that was about twice as big as it so was really loosely shipped in the box. It ended up leaking some really didn't lose much product but kind of made a mess inside of the box and on the outside of the package.

Love it

I use this diluted to seal cement candle vessels. Works great, and zero wax seepage so far.

Works as advertised.

Used it once. Seems to have sealed my leaking head gasket. Product isn’t packaged well at all. Not sure who’s fault that is.

Excellent quality and price for Sodium Silicate. I use this for my foundry, as a binder for insulation and refractory hot face. Little known fact, a 1-2% TSP (trisodium phosphate) addition will increase the mechanical strength of sodium silicate by 20-40%. I dissolved 400g TSP into a 2L bottle, and a tablespoon of this solution is added to 200mL of sodium silicate before adding any aggregate; my bricks and plinths are much stronger. Don't get ripped off paying inordinate amounts for tiny volumes (pint, 1/2 pint) for sodium silicate when a gallon of this is ideal and of such value it can't be beat. If you're looking for potassium silicate, look for gardening products as a soil additive.

Great heat barrier when mixing with volcano ash

I purchased this product to build a DIY forge. Used it to bind the foundry lining, the product is a perfect thickness, mix’s well. Great value for the money, A gallon goes a long way. I actually bought a second bottle so I can do future projects.

Works as well as expected. Can also.be used for multiple purposes including cleaning.

It’s thick and does the job almost too well
