many tiles are either powdering or flaking

Hi,
The original owner of my home (I'm the third) installed slate tiles outside on a base of concrete, I believe. I'm not sure what kind of slate it is, but it's dark grey with some brownish hues.  Anyway, the slate doesn't seem to be weathering well in some areas.  On the covered front porch, many tiles are either powdering or flaking (with thin, brittle layers washing away with just a simple hose spraying). In the back where it's sunnier, some of the tiles are doing the same thing, though to a lesser extent.  In a few places, the tiles seem to be doing fine.  We're in a Southern California coastal valley where it gets both very hot (95ish for a month or so) and very cool and damp (when the ocean fog rolls in).  A few years ago, we had someone spray the slate with a water-based sealant, but that didn't seem to do much, and I'm sure it's long since worn away.  I see lots of conflicting info about sealing or treating slate.  Is there anything we can do to both protect our slate and, potentially, make it look a little more lusterous ("wet") without spending a bunch of money?  I appreciate any expert advice you can offer.  Thanks.

Is slate in general hard to upkeep?

I saw the perfect color of tile that I have been looking for on ebay.  It is called African Gold Slate Tile.  Can you give some advice on this type of product?  Is slate in general hard to upkeep?

The panels have grease stains from food

I bought a dining room set that has blue slate panels in it. The panels have grease stains from food.  I was advised to remove the stains with soapy water containing
detergent with a degreaser. That made the spot worse. It is now dark in that area and is worse than before. How can I get the slate cleaned

problem Im facing is getting a professional finish

Hi there
I wonder if you can help
I have recently installed a natural slate tile floor in our bathroom, I am pretty competant when it comes to cutting and laying the tiles so in general I am pleased with the job, however the problem I am now faced with is getting a professional finish. The tiles lack polish even after using tile cleaner and sealer and the black grout has now gone very pale, these 2 issues give a very poor finish to a job which was a lot of hard work.
Any advice to get a permanent finish would be much appreciated.
I look forward to hearing from you.
Regards

Cementing slate paviors

Hi
I have a large garden patio which was paved in fabulous Welsh slate two
summers ago. I'm very pleased with it but the upstands, that run around the
edge keep coming away from the concrete of the patio. I have tried to effect
a repair with the Nicobond exterior tile adhesive (the tilers used this
stuff) but now all the upstands have 'peeled' off. Can you recommend a good
cement for a permanent solution?

black honed slate countertop

 
This is a question for an expert regarding problems with slate countertops.
I would be eternally grateful if one of your panelists could advise me how to remove lemon/lime stains from my black honed slate countertop..............I have tried using the fine screen mesh, warm water and dishwashing liquid methods which reduced the stains slightly, however I am hoping that there is a more successful method........PLEASE advise.........

granite patio table top

I and my wife recently purchased a round 44" patio table with a granite top.  It is Garden Treasures Classics product from the Java line.  The table top appears to be granite "tiles" grouted into a mosaic of concentric circles.  We have purchased a good quality PVC cover primarily to keep it free of outdoor debris.  What kind of treatment and/or maintenance does this type of table top require?
Thanks,

Wine stains

Help! Have spilled red wine onto what looks like a sandstone fireplace. I
know that's not much to go on, but it's all i really know about the stone,
apart from the fact that it is sandy coloured and red wine stains it! It is
my parent's fireplace, and dad will be pretty grumpy about it tomorrow.. not
suprisingly. I have tried supermarket stain removals that we have.. but was
hoping that you could let me know of any other product or tecnique of stain
removal that could help.

Thanks for your help, from a worried sarah

How can stones be cleaned of lichen growth?

We live in Colorado on 6 acres with lots of local sandstone. My wife has the
idea to collect this stone and arrange with a local stonemason to lay a
stone floor and build fireplace out of this local rock.  This seems very
labor intensive.  Do you think we can find someone to do it.  How is
sandstone for interior use, especially a floor.  Will it show stains, can it
be adequately sealed?  Are airborne silicates a concern?  How can stones be
cleaned of lichen growth?

sealant that will protect stone in chlorine pool

 I am trying to educate myself on ways to clean and hopefully seal (if not possible, at least slow down) the efflorescence at the waterline of our pool.  The coping and waterline tile is sandstone and within 2 years has developed a distinct and unsightly white line.  The advise I have received so far is if power washing with acid doesn't do the trick (and it hasn't) that glass bead pressure blasting in the only thing that will remove it.  Is there any sealant that will protect the stone in a chlorine pool?

I'd appreciate any help I can get!!
Thank You.

sealing sandstone

We have moved into a home with a backyard of Arizona sandstone.  It includes a salt water pool.  There are a few stones by the pool deck that are always peeling.  My concern is, if I apply a sealer it will only make the peeling in deeper layers.  Any suggestions on Product or application?  Cost is a factor.  There is over 
1500 sq ft of flagstone.  Thank you, Diane, Arizona

'dry-look' or a high-gloss 'wet-look'

hello,
I've perused thru your website, and at least now feel somewhat qualified to ask the right questions regarding sealing my new patio.  I live in Texas and just had an Arizona Buff sandstone patio installed.  To me, the question of whether or not to seal is not the issue.  What I'm concerned about is whether or not going with a wet-look sealer is appropriate.  I personally like the wet-look, since it brings out the various reds & tans embedded in the stone. 
I have been told that my two choices for sealers are a 'dry-look' or a high-gloss 'wet-look'.  One supplier advised me that going with a wet-look seal will cause the surface to be too slippery when it's wet, and a dry sealer would be safer.  (wouldn't a sealed patio be slippery if it was wet anyway?)  In addition the product he was selling (Prime-A Pell 200), would only last a year on sandstone, since it's a relatively soft rock.  Is there a wet-look / color enhancer product out there for sandstone that will last a reasonable amount of time...and won't become a hazard if it gets wet?
thx,
Brad

I'm learning a lot from you professionals

I'm learning a lot from you professionals. Thank you
for your knowledge.
I will need to stabilize and/or replace some "Moinkopi
Sandstone" in Holbrook Arizona on an old building.  Is
there any organization I could get in touch with that
could teach me what I need to know, or that could help
me with any testing that I would need to do?  I would
really appreciate any information you could give me.

Dear Sir/Madam,
What can you paint on a sandstone statue to protect it from the weather if you want to put it in your garden?

sealing sandstone

I help maintain a resort/spa that has a lovely hot springs facility on the
ocean. The floors are all sandstone - exposed daily to rain, showers, hot
springs water and anything else that hundreds of people every day bring.
It is not sealed and is in good shape, however the bathrooms are
developing a problem because any urine that misses the toilet is soaked up
by the stone and they are becoming very smelly.  We're going to try
cleaning the stone with bleach and/or a natural enzyme product intended
for pet stains to see how that goes, but we would love to seal the floor
to help prevent this from being a consistent problem.  I have done some
online research and there seems to be much debate about sealing sandstone.
 Maybe wax is the answer for us? Or just regular linseed oil applications?
 I don't want to use anything that can contribute to a more rapid
deterioration of the stone.

Thanks for your help,
Lisa

what sealer should I use: or should I use any ?

The entire surround of my house is in sandstone - need I say more !!!  I find the best way to clean it is with a karcher water blaster and it works excellent BUT, there is always a BUT isn't there ? what sealer should I use: or should I use any ? should I just continue using the karcher water blaster abut 3 times per year - it takes about 4 days to do all !!! I am concerend that the sandsone may detiorate with constant use of the water blaster but I do like that rugged look when it has been cleaned instead of the "oh so clean and unatural look"
Many thanks for any suggestions.
cheers

salt have a significant affect on the sand stone

Hi -
I have recently purchased my first home, a 1920's brick in Shaker Hts, OH - everything I've ever thought I wanted in a home, and more (I'm sure!!).  The front entry way has sandstone steps and landing, and during the winter months I put salt (the cheap stuff in a bag) on the steps and walkway to deter ice accumulation (trying to protect the mail person).  Does the salt have a significant affect on the sand stone or is it a natural occurance (errosion) that I am seeing now. I do see what appears to be sand, and I've noticed that there is now a gap between the threshold of the front door and the sandstone landing.  It looks as if there were some type of masonry caulking in place before. 
Any clues you can provide will surely be appreciated.
