Sodium Silicate 40% - Water Glass (1 Gallon)

Works! Will order again.

good item

While it works as instructed the down side is due to its liquid state, if you concrete crack is too deep you would find out running out the product.

This has been use as a wood sealant and fire retardant for centuries. NO one will find it the big box stores because its pennies per use. check it out you won't believe what it can do.

Pick your concrete at home indispensable product...

Appears to be PQ's N grade sodium silicate or an equivalent offset repackaged in gallon containers. Great for lab scale work.

Great Product

Still testing on wood. Works great as a box and label sealer.
