[TheForge] Hydraulic Cements etc

[Ralph Sproul]

        Hi Don, Thanks for this suggestion on product to try.

    Does this material in the tube have a  consistency that would hold
something horizontal? or is it to fluid right out of the tube(after mixing)?
If it is similar to clear silicoln caulking in consistency - that might work
fairly well in horizontal holes.

    I've used the Rockite in horizontal holes and used plasticene modeling
clay to make a sort of vertical dam/funnel to pour into.  The problem with
that is you have to do one hole at a time, as keeping track of the hardening
rate is mandatory to rough out the surface just as it's setting, as you
never get a smooth face pour with a funnel like clay cover.  The oil in the
clay allows it to stay seperate of the Rockite, and the clay adheres
(somewhat) to the rock/granite/masonry.  A prop pole or stick is needed if
the hole is large and the clay is weighty and tends to fall right off.

    I used to have some of that ram wool......which was a lead steel wool
like substance.....but ran out of it.  Does anyone know of a source for
that?  It used to work well in horizontal positions.

Ralph
