Yep - I'm back with more questions.
So I bought some really cheap 4" resin diamond dry polishing pads, and the saying "you get what you pay for" is true. I did manage to polish 10 linear feet with them, but now the higher grit pads are completely bare. I need to bite the bullet and buy some better pads, but on average how long do the more expensive pads last? Is it worth spending the money?

The pads can start getting pretty expensive. I have found that if I just make sure to buy enough of the Velcro sand paper pads ($.49-$1.24 each) they work ok.
You can get dry or wet polishing diamond resin pads for around $14-16 each. They last a little longer.
If you are not in the Bix I would stay with the cheap pads.

Jerry - thanks for the answer!
I got ahold of a guy here in town that does some stone work, and he said that he would loan me his set of diamond pads so that I can get this job done with (we have VIP company coming into town on Sunday). Talk about lucking out!

Back to the original question - how long do the more expensive pads last? Any guesstimates on linear feet?

That would depend on the material/hardness of the stone you're polishing.

If you're polishing a soft marble,you can probably use ALPHA pads,which are used dry. They cost about 5-6 bucks a pad...and come in course,medium,fine.
They fit on a 4.5" disc/side grinder,and have an arbor adapter,if need be. I use a Makita with those.

In the last 3 weeks,I've polished like 120 lf of granite,with the wet pads/velcro.....and still have a ton of meat on my pads.

Sounds pretty cheap for pads.... i pay 20$ - 30$ for each pad. One thing
to extend the life of your pads is to ride the surface you are polishing evenly
with the pad. Tilting pads will wear the edges faster. Ive never heard of
wearing out a set on 10 lineal feet. Master Wholesale.com (http://www.masterwholesale.com/) has a selection of pads. Theres a #
on the website as well so you can call em up and ask about the pads if you
buy from them. I use a local company but i dont think they have a website.
Good luck

Thanks everyone for the responses!

Hamilton - I am beyond embarrased to admit that I bought them off ebay for $48 + shipping (a set that went from 50 grit to ). They did work, but they certainly wore out quickly. :o

Whoops - forgot to reply to Autoplay;

It's all granite (tiles).
The type I am working on right now is Volga Blue...... I think I am going to re-name it Spalling Blue.

It is beautiful though.

The stone guy I talked to today told me what kind of pads he uses, and I swear he called them Gen-X, but I can't find anything online about them.

'course I don't listen to what people tell me.....

NVC

Hi Lisa,

I use Gen-X pads and I get 'em from Braxton & Bragg 1-800-575-. A set of 9 runs about $299.00 & singles/replacements run $35.00/ea (no affiliation with 'em whatsoever)
They can be used either wet or dry. Running them dry at rpm.

Running them too fast will burn them up, so they must be used with a variable speed grinder that can be slowed down to the proper rpm. Maybe this is what happened on the e-bay set?

hope this helped,

Mark

Hi Mark;

I used the cheapo pads with a variable speed grinder, and never ran them over rpms. I think they were just poorly (cheaply) made.

Oh well - they were a good introduction into how to polish edges!

I'll be interested to see the difference between those pads and the Gen-X ones.

If you were to bite the bullet & invest in a set of Alpha pads you wouldn't be needing to rename that Volga Blue. I had no chipping issue when I made my kitchen out of this stone. The Alphas polished up the edges every bit as nice as the face, perhaps even better. I probably polished over 100 lin ft, some of it radiused, of 3cm thick Volga, and did not notice any wear on the pads.

These are WET pads. To my knowledge all Alpha's diamond pads are for wet use only, unless they cme up with something new recently.

Alpha does make a dry pad...for spit shining marble. Works good on the softer/lighter marbles. They cost about 5-6 dollars per pad. The come in 3 grits....Course/medium/fine. I'll look in my garage later on tonight,and try to get a pic. Ahhh I didn't read completely lol.....as you said DIAMOND/wet. You're probably right.

The Alpha dry pads I have,are made from some compressed stuff{whatever it is lol} and are strickly for DRY use only. If you try to use em wet.....the pad material will bloat and disinigrate.

housefire

Thank you all for your replies - I am going to go pick up the Gen-X pads as soon as my husband gets back from scuba diving. I will let you know how they work out!
I still have an 8 foot vanity to do, and two smaller ones, and then my kitchen counters that will be about 20 lf, so I will probably look into getting some better pads so I don't have to borrow someone else's.
I had better have finished pitchers to post by Sunday, or I will be in biiiig trouble! :)

Levi the Tile Guy

I like the gen-x pads a lot. One word of advice try to do your polishing wet if you can, it saves the pads, and I think turns out nicer

Autoplay

Here's a few pics of what I use.

The wet/diamond pads are made by Pearl. The Pearl 1's I have range in grit from 50 to ,and a buff pad{which I never use} With those,I also have a and a grit pads which aren't made by Pearl,and I forget who/what brand they are. I use a Makita vari speed,with the standard velcro head.

I found 1 of the Alpha dry polishing pads that I use,and with it in the pic,is the thin backing plate,that comes with it when you buy a box of ten,or ask the sales-lady politely/grin......which attaches to a standard side grinder. I use a Makita. Color red is course,Blue is medium,green is fine. I only found 1 in my garage,I think the others are buried in my toolbox lol{I don't use the Alpha dry pads very often}

I just got back. He loaned me a whole bunch of Talon brand dry pads, and a bunch of Dryflex dry pads. He also gave me about a six inch thick stack of Alpha sandpaper discs of various grits that are velcro backed.
Pretty nice, huh?
I compared the Talon & Dryflex pads to my el cheapo ones, and..... well, there was no comparison.
You never know - I just might get this done by Sunday! :shake:

Kewl Lissa,

He loaned this all to you?!?!? A complete stranger?!?!?!

Tell you what, would you be insulted if I asked you to post a few pictures of YOURSELF alongside those promised photos of your beautiful granite?

Ive never taken notes on specific feet but my dry pads usually last a year or so.
seems the lower grits wear out faster. keep in mind i only do granite once in
a while, several times per year. maybe 100-150 lineal feet? Ive got a couple
pads - that are a couple years old.

These are Alpha PVA pads, for dry use on marble. I'm fairly sure the have either silicon carbide or aluminum oxide abrasive imbedded into them.
You can read a technical description on them on this page:

If it's not too much to ask,can you wear a 2 piece bathing suit.....and have someone take your picture,while you're laying out on top of your new counter? ;)

Hope everything turns out well for you!

NVC

What Rich said Lissa :D

Rich,

That 2 piece suit might fly in Florida, but here in CA it won't be up to code or pass inspection, and the inspector will say 'take 'em off'. (including some seismic tests) :D

Mark

housefire

I'll be happy to wear a two piece for ya. It will be a pair of jeans & a t-shirt. ;)

NVC

That's actually my favorite kind,<shrug> but the wife would kill me, or do some'n horrible to me in my sleep, if I requested such a pic. ;)

So go get to bull-nose'n :D

Little tip on the b.n.: Hit it with the 80 grit first (or a diamond coarse wheel) and put a 45 degree chamfer on the edge (knock the top corner off) The width of this strip determines the size of the bullnose. Try to keep the width of this strip continuous, to avoid ripples when you sight down the edge.

hope this helps,

Mark

Apparently I uncorked some pent-up sexual harassment there.... little did I know what I was starting. :rolleyes:

JRTX

Geesch...was so deep into the banter about Lissa and how she got some guy to loan her a bunch of pads....that I almost missed NVC's comment on using a guide strip.

Regarding the guide strip....are you using this to control the depth of a profiler when used on a 4 1/2 inch grinder?

Hmmmm...no pics yet....guess the job ain't finished yet.... :shrug:

This is a question that a lot of readers and other detailing enthusiasts new to machine polishing ask quite a bit.  Having the correct amount of polish on the pad is very important because it ensures you get the results you&#;re after without using too much or wasting time on non-necessary polishing.  Due to the many pad and polish combinations out there, all the different machines, as well as different goals from a polishing job, it&#;s really all but impossible to give the &#;right&#; answer for every scenario.

That said, my focus here is to give a sort of general guide on applying polish to pads.  I almost exclusively use the Flex XC VRG polisher with 5.5&#; Lake Country Pads.  One important factor to consider is whether you&#;re using a polish with diminishing or non-diminishing abrasives.  As you&#;ll see below, I prefer to use a lot less polish on the pad when using diminishing abrasives because those polishes typically have longer work times and you&#;re better off using a proper amount per section of paint.

First off, here&#;s a few photos to explain my process when using Meguiar&#;s D300 Correction Compound with a 5.5&#; Lake Country Orange Pad.  The following process is also used with other polishes utilizing non-diminishing abrasives, such as Meguiar&#;s Ultra-Cut Compound M105 and Meguiar&#;s Ultra Finishing Polish M205.  I like to first prime the pad well over the entire surface area.

I do this by pouring out some polish in a circular pattern over the entire pad&#;

Then I spread that polish out with my finger to completely prime the pad&#;

Once that&#;s done, I&#;ll apply small amounts of polish to certain areas I may have missed the first time around&#;

Now my pad is ready to polish a section of the paint.  Once I&#;m done polishing that section and using a brush over the pad to get rid of dust and residue (for more info on cleaning pads please refer to my article Pad Cleaning During and After Polishing), I apply some more polish to do the next section.  Following the first priming of the pad, I typically apply the following amount or less&#;

As much as it&#;s important to apply proper amounts of polish to the pad during a polishing job, it&#;s just as important to know when to call it quits with one pad and start with a fresh one.  I also go over that in more detail in my above mentioned article, but in short, pads get saturated with polish and paint residue, so after a certain point they don&#;t work nearly as well as they should.  Thus, it&#;s necessary to replace them as often as the job calls for it.

For diminishing abrasive polishes, such as Menzerna Micro Polish SF (PO85RD), it&#;s necessary to use a lot less polish and no priming is required.  For these polishes, I use the following amount of polish&#;

I use this much polish on the pad whether it&#;s the first polish application to a fresh pad or second, third, etc.  Regardless of the type of polish though, the pad will get too saturated over a few sections, so it will require replacement with a new, clean pad.

That said, I do encourage others to use this as only a general guide, while experimenting with both more and less polish.  It has happened plenty of times where a helper of mine, with only 2-3 months polishing experience vs my 5-6 years&#; worth, finds a better polish amount to use and/or technique with the machine that results in slightly better results.

I hope this is a helpful guide for many readers out there and thanks to all for reading!
