i've heard rumors that it's just repackaged grout, does anyone here know for sure? i'd hate to pay 75 bucks for 11 dollars worth of grout if that's the case.

I heard it was a mixture of hydraulic cement and grout with some sort of resin as a binder .all I know the stuff is better than plaster of paris or fibreglass resin( we used the resin and it would soften from the heat of the engine and flow in the passages and the plaster would disintegrate from the hot water )

Part of Randys cake mix?

I don't think Randy would part with anything that has to do with cake .

More like my Exwifes pancake mix otherwise known as manhole cover mix .

A good friend of mine owns HardBlok..It's a pretty high tech, lab/field tested product.
We used a ton in our day.
good stuff..worth the $$'s.

I've used it for six years never a problem

Take a tip from a retired Boiler Operator - use refractory cement. It'll stand a lot more heat than an automobile engine will produce and cure high pressure water leaks too. Over the years I've dragged home a good many bags of it for local racers. Just don't mix it too thin and make sure you vibrate the block with a palm sander or air chisel when you're pouring it.

pre-Hard Blok...we did that.
Hard Blok is Bitchin' !
Excellent product.
worth the little that it costs
