Surface sealers soft stone

[Charles Kibby <chzmo@xxxxxxxxxxxxx>]

I was going to avoid this thread because there is no easy
answer or miracle cure, but I couldn't let it be. I've got
over 15 years experience in the restoration of historic
masonry structures and I've used everything from
alkoxy-silanes to beeswax.  In the course of that experience
I can testify that there is no long term solution to your
problem.

ALL sealers/consolodants/water repellants/protectants will
ultimately fail within 7-12 years, regardless of "UV
Resistance" or any other claim, real or spurious. All stones
weather, some faster than others, and to expect stasis in
this regard is to be eventually disappointed. If you are
serious about conserving a stone as soft as alabaster, then
keep it out of the rain and weather.

Having said this, you may still want to research the subject
of consolodation and water repllancy - check out the website
of ProSoCo - one of the largest manufacturers and
distributors of stone cleaning and restoration products in
the U.S.

I hope I didn't put a damper on your project. Good Luck
