pic1, custy is concerned about moss returning, is there anything that can be done to prevent or delay this, also what chems and methods are best for cleaning and sealing. indian flagging.

pic 2 not sure these will look any diff after cleaning but again, chems and methods including resealing.

thanks in advance.

Hi Derek,
Ive had good results on Indian Stone using a fairly high Alkaline solution. Its always a messy job doing a patio, dont forget to take direction of drainage into account. A good stone sealer from B&Q should keep the Moss away. Cant remember the name but that's what I used on some Granite blocks on my garden about 8 years back - no moss or anything grows on them, they are still clean as a whistle.
The Travertine floor tiles, again use a good Alkaline stone cleaning solution (DON'T use an Acidic) and rinse off with plain water. As for sealing, I use a water based Flurocarbon from Alltec. The natural holes in Travertine will always look darker.
Dave.

cheers dave.
i'll check out b n q tomoz.

Derek,

I'd use a hard floor spinner on the patio, but if it's sandstone I'd work up slowly on the pressure in case it's softened up over the years.

On the trav I'd use a decent alkali cleaner, but wouldn't use high pressure as you can blow grout/resin out of the holes in the trav (if it's filled), so a normal slow rotary is best.

Seal both with Aquamix Sealers Choice Gold - 10 to 15 years protection, and water based so no horrible solvents wafting around.

No acids on either of them, stay away from the dark side.

Very good reply. 

[derek west]

cheers for that chris

only rotary ive got is the rx20 with hard brush, anygood? or should i invest and if so what would you suggest.

thanks

[Cathedral Floorcare]

I've not got an RX20, but I have seen one in action and I reckon you'd be fine with that as I seem to recall it works well at low psi - down around 400psi the travertine should be ok (test first of course). As for rotaries, invest £150 in a second hand one from A3 Machines, you'll make the money back in a couple of hours! I spent a load of money importing a Hybrid Turbo from the USA 18 months ago, and I reckon I've used it 5 times. The Victor is always first off the van.

Think about hard floors like you think about carpets - it's all the same really. The only difference is recognising the materials, and most customers can't wait to tell you if they've got a particular type of stone. Once you know that it's easy. And they don't shrink. 

edit; Forgot to say - the RX20 brushes come in different grades don't they? You'd need to check that it isn't too hard for either floor, or you could scratch them.

Hi Derek just got in been working all day on 320sqm of nonslip tiling chemicals used as follows

CLEENOL POLISH STRIPPER ALKLINE PH 13
SELDON STRONG ARM ALSO GOOD TASKI FLOOR CLEANER NOT BAD ALL CHEMS ALKLINE WITH HIGH PH

DILUTE APPLY WITH MOP WAIT 10 MINS ALLOW IT TO GET TO WORK
ROTARY FLOOR BUFFER/POLISHER MINE IS ONLY 150RPM BUT DOES THE JOB
FITTED WITH SCRUB BRUSH HAVE ALSO USED BLACK OR GREEN PADS

NOW EXTRACT OR MOP UP THE MESS
NEXT I USE FIB FAB RINSE PROCHEM TO BRING THE PH DOWN TO 7 OR JUST BELOW WHITE VINEGAR ALSO WORKS WELL.  DRY MOP WHEN DRY APPLY THE SEALER

MAKE SURE YOU GET THE PH DOWN AFTER USING THE HIGH PH ALKLINE CLEANER QUICK PH TEST AFTER RINSE OR THE SEALER COULD REACT JOB DONE

[derek west]

acid rinse!

no acid rince!

aaaaaaaaahhhhhhhhhhhh.

heres what am gonna do.

test a tile with speed stripper, spray on, hand brush scrub, wipe off to see results. if okay

seal skirting and units. spray on stripper, allow to dwell then scrub with rotary or sebo (with downward pressure)
rinse off at 400 psi with sx12 using water only.

leave to dry over night then return and apply aqua mix gold choice, allthough i'm not sure how to apply it just yet but the supplier should tell me or the instructions on the tub

tadaaaaaaaaaaaaaaaaaaaaaa

what ya reckon?

[sherco]

Derek that sounds a good plan. I would use Aqua mix Heavy duty tile & grout cleaner myself. To Apply the sealer i use a Harris paint pad, most diy places sell them. Any problems give me a ring, numbers on my web site.

[Steve. Taylor]

Derek acid or no acid get the ph down before sealing or it goes silvery grey used this method for 11 years  have yet to have a problem. are you feeling lucky punk go for it

sherco
i'll put it in me phone on speed dial just in case, pootin me pants on this one. but i did on me first carpet so newt new.

steve i'll get me litmus out, oooo errrrr misses.

i'll do a test just in case but i think the sx will flush it out plus the stripper i'm using says no need to rinse. back of the net.

[sherco]

Just remember No acid cleaner on Natural stone, also be very carful using coloured scrub pads on natural stone as the can stain the stone edges, fine for ceramics, porc etc. Also stone needs to be completely dry if using a solvent sealer...

[Cathedral Floorcare]

You'll be fine Derek, your planned process sounds fine. I'm with Sherco on the Aquamix stuff too, can't beat it. And using products made by the same manufacturer reduces any risk of them not working in tandem with each other.  

If you can't get Harris paint pads the B & Q own brand ones are pretty good too, and get a small paint tray to hold the sealer.

I've had good results with Viper Venom.

[Dave_Lee]

Second that, Viper Venom is as good as it's name.
