Sodium Silicate 40% - Water Glass (1 Gallon)

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...

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.

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

Works! Will order again.

Great Product

I shall start with my concrete landing and then move to the sidewalk to increase hardness of the concrete.

I have used water glass for head gasket repair for years , this works perfectly for the application
