hi all i'm really new to this. i dont know what is a good ratio to mix
to get a good cement texture. i will be getting my supplies from home
depot. i'm trying to make a waterwall and pond for my back yard. i
have been reading around this newsgroup and some guy said you have to
seal the concrete with some kinda seal . this is what he said. "If I
remember my old cement pond making days correctly, when the
cement has apparently 'cured' you can brush a solution of water and
sodium silicate over all surfaces, when that soaks in and dries it
seals all surfaces considerably" what is sodium silicate?? i tried
asking the guy at home depot and he looks at me funny . go figure. any
help will be great.....

newbie ponder

I used 3:1 sand to cement and added liquid frostguard (sort of a red
liquid stuff - febeze in england). Allow to cure for at least a week before
sealing, longer if you can. I used a pot of sealant, then undercoat
then top coat all from the same manufacturer of pond paints. Given that
it should last 30 years, the cost was negligible at about 30 ukp.

Sodium silicate is Na4O4Si and is excellent for preserving pickled eggs,
are you sure thats what you used?
