Why is hot better than cold?
-
That's a very sweeping statement that is not true in all circumstances.
It depends on the surface being cleaned, the level of soiling and the type of soiling you are removing.
On some, it will make no difference whatsoever if it is hot or cold, on others hot will just make the job easier and quicker and on yet others cold simply won't do the job.
In fact on some, hot would be a fatal mistake to make!!!

would hot be ok on granite and concrete driveways for removing oil and grease
-
Not sure about a granite driveway (man that must be expensive) but if the surface can stand steam, then hot would certainly have more of an effect on oil than cold water no matter what the surface, however you may need some chemical to shift the oil successfully if it is old or very dirty oil.

Is the granite, sealed or unsealed, polished or unpolished ?

Hi
The granite is cut bricks and about 10000m2 (like cobbles but flat bricks) and about 2000m2 of sandstone.
I am at a bit of a loss!
If i was to use my machine it would take me 100 days +
I only have 40days. (get two machines I hear readers say)
I was looking at a Demon rotrary attachment (£735)> I dont know?
Are there any other machines out there?
Maybe something that pressure washes and extracts?

Do you really mean you have 10000m2 or do you mean 10000 square metres?
By my reckoning, one man should be able to do 10000 square metres in 15-20 days maximum, but to do 10000m2 (100,000,000 square metres - yes one hundred million!!!) well put it this way you, your kids and probably your grandkids would never have to worry about work again!
I imagine it is the former figure which, unless my calculations are out (which if they are, please tell me) is very acheivable by one operator like I say, in 4 weeks or less.

whats the difference
10000 square metres is the same as 10000m2, or is it not?
you've confused me now andy
-
BIG difference... huge!!!
10 metres squared (10m2) is 100 square metres (10m by 10m)
10 square metres is 1m by 10m.
Price difference example - £2 per square metre to do 10m2 - £200... to do 10 squarer metres - £20
If the customer has given you the measurements then make sure you go and measure it yourself to price it right.

Andy, sorry you really p me off with this! We all and you know exactly what he means, it's sq metres. I thought the idea of this forum was to help and not pick at every statement posters make!
Anyway back to real life, I can do at least 600 metres (sq metres Andy) a day easily with my fsc single manned.
-
To be honest, I don't care if I p you off, if this guy prices this wrong then it could close his business.
I would rather make sure that he is not dropped in it from a great height and risk p-ing you off than not say anything and see another honest hard worker trying to scrape a living go down the swanny because someone like you assumed all the i's were dotted and t's were crossed.
Sorry to sound defensive but I alsmost made this very mistake early on and thanks to a colleague pointing out my mistake, I was saved from certain failure.
I was not intending to sound patronising, I simply want to make sure this job isn;t his last.
Thank you

thanks guys
100 meters long *100 meters wide 10000 square meters.
I just remeasured the area on google earth and got 12500 square meters
I figure to buy a 21" Mosmatic Professional Series
Stainless Rotary Cleaner With Vacuum Recovery and I also figure that it will take 25 days if the stats for the mosmatic are right.
Next step. To price it up!

Nice one.
Good luck

Sam,
Do you have a photo you could send me of the granite?, are you sure this is granite, as stated before that is an expensive driveway. Granite usually comes in slabs not small brick/cobble size's but maybe it is.
-
Sam, I'm with you on this. You obviously mean 10000m2 is 10000 square metres as would most people, but andy seems to write 10000m2 and mean that you square the 10000 metres. I have never heard of it done like that before but I'm not saying he is wrong. Anyway hope you get the job and earn sh*@ loads of money for doing it ;D

I can send a pic.
As it stands today. Owners say granite (rough cut pavers)...I disagreeociates say granite crush > adhesive (concrete).
loads of oil.
loads of moss.
little rust.
how do i get your email addy

roger got it i will send a pick tomorrow

Just to clarify
metres squared is not the same as square metres...
10 metres squared (written mathematically 10m2) is 100 square metres... ie 10 metres by 10 metres
10 square metres is 10 square metres, ie - 10 metres by 1 metre
square metres has never been written m2 as it is something completely different... O'level maths stuff this...
If you try doing the same calculation with cubic metres measured against metres cubed and it actually becomes clearer.
I did not bring this up to get into a deep discussion but to make sure that sam1975 didn't get stung.
Sorry if I have caused any confusion.

I think andy was right to double check the measurements, I have in the past been very close to making this mistake (It would of been a disaster), if some one had offered me the tip at that time it would of saved me alot of hassle.
As always its important to double check the information customers give us because even if we know what were doing it doesnt mean they do.

Well every day's a school day. I didn't know that. Thanks for putting me right.
I always thought m2 meant sqaure metres.
Mike
-
this is an excellent point, me not good at maths so i did not realise either! ;)
-
Can I chip in my two penn'orth.
100m2 is 100 square metres. 10m x 10m.
If it was 100m x 100m it would be expressed as :
(100m)2. Not use of brackets to isolate the factor.
100 x 100 is indeed 10,000.
-
good point.
-
thanks for that eric, I'm not quite as daft as i was begginning to think i was
-
ou don;t have to take my word for it, this is the explanaition as given by a doctor of mathematics...
"If this is a mile:
+---+
then this is a "one mile square," a square one mile on each side whose
area is called one square mile:
+---+
| |
+---+
and this is ten square miles:
+---+---+---+---+---+---+---+---+---+---+
| | | | | | | | | | |
+---+---+---+---+---+---+---+---+---+---+
But "ten miles square" (or "ten miles squared") means we make a square
ten miles on a side:
+---+---+---+---+---+---+---+---+---+---+
| | | | | | | | | | |
+---+---+---+---+---+---+---+---+---+---+
| | | | | | | | | | |
+---+---+---+---+---+---+---+---+---+---+

+---+---+---+---+---+---+---+---+---+---+

+---+---+---+---+---+---+---+---+---+---+

+---+---+---+---+---+---+---+---+---+---+

+---+---+---+---+---+---+---+---+---+---+
| | | | | | | | | | |
+---+---+---+---+---+---+---+---+---+---+
| | | | | | | | | | |
+---+---+---+---+---+---+---+---+---+---+
If you count, or think a bit, you'll see that 10 miles square is
actually 100 square miles, ten times as much as 10 square miles."
It all depends on whether you say miles square(d) or square miles.
-
So how much is ten cubic miles
;
-
10 cubic miles is 10 cubic miles.
10 miles cubed (10 x 10 x 10) is 1000 cubic miles
:)

what about 100 miles squared? im getting confused now. ???

You would probably need to sub it ;)
