Isn't sodium silicate what you get when you dissolve glass in lye?

Speaking of sodium silicate. The stuff is getting 
harder and harder to get for a reasonable price, at 
least around here. It's a "Hazmat" and needs all kinds 
of special packaging, handling, tracking, etc. so the 
cost is high enough you have to special order it.

Yesterday or the day before I was watching a a home 
renovation show and they were sealing a concrete slab. 
I don't recall the product name but it was sodium 
silicate in a 5gl. bucket and supposedly available at 
your local concrete supplier, building supply, etc. 
hopefully without hazmat hassles.

I haven't checked it out but thought it worth passing 
along right about now.

Fortunately we don't have fleas here but I could sure 
do without the butt sniffing.
