How to Select Diamond Resin Pads for Concrete

Choosing the right resin diamond pad plays an essential role in effectively polishing concrete. If the contractor chooses the wrong pad it can result in a costly mistake.

If you&#;re trying to decide what kind of pad you need, you should consider a few factors before making your purchasing such as the bond of the pad, the grit of the pad, wet vs dry pads, and of course pricing.

Let&#;s take a look at these below.

Why use diamonds?

Diamonds are one of the hardest substances on earth, making them ideal for grinding extremely hard surfaces such as concrete.

Synthetic diamonds are most commonly used due to the ease of which they can be sorted and graded. This results in more control of the shape and hardness of the diamond. A diamond like this gets more consistent results in grinding and polishing.

Explaining the bond of the pad

The bond serves a couple purposes. Its primary function is to hold the diamond grit in place for the crystal to cut, grind, and shape the concrete. The pad also needs to wear appropriately in order to expose new, unused crystals to the surface.

The pads work by keeping the sharpest diamond grit on the surface to achieve the desired result. As a general rule the following guide will help you achieve the best results when using a resin:

Hard Bond: best for soft concrete
Medium Bond: best for medium concrete
Soft Bond: best for hard concrete
Extra soft bond: best for very hard concrete

Wet Vs Dry Pads

Often you need to watch for whether the resin pad is designed for a wet or dry surface.

When it comes to choosing wet vs dry it is often a preference of the contractor; there are many advantages and disadvantages to both. The main difference between the two is the amount of dust control. With wet pads you will create a slurry paste, and with dry pads you will create a lot of airborne dust.

With either choice you will need a cleanup process to deal with the slurry or dust.

What to expect when comparing price

As you research what diamond resin pads you should buy, you will come across a wide range of pricing. There are a few reasons for this but one of the common reasons are the type of resin pads.

There are two types of resins for polishing: hybrid and polishing pads.

Hybrid resin pads are often used as a transitional pad between a metal and a polishing pad. At 6-8 mms, they are usually a bit thicker. Quality hybrid pads should last between 5,000 &#; 10,000 square feet.

Polishing resin pads have more of a plastic appearance. They are thinner than hybrids, and are typically 2-4 mms thick. Polishing resin pads should last between 10,000 &#; 15,000 square feet.

Overall, the price you will pay depends on the quality of your diamond pads. With less expensive pads you may only get 5,000-10,000 square feet rather than 10,000 &#; 15,000 square feet. The diamonds might not stay in the bond, making the pad useless.

A safe bet for anyone looking for a good quality diamond pad are some of the top brands in the industry such as Husqvarna, Lavina, Truloc, Stonecrete, STI, CPS, and many more. We carry a variety of these brands, so be sure to check them out.

Dry polishing pads with longevity? [Archive]

View Full Version : Dry polishing pads with longevity?

housefire

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,

Free diamond pads, can't beat that with a stick. Might oughta bring 'em back with a box of cold beer, he sounds like a nice guy. :D

have fun polishin' and wear a dust-mask

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.

housefire

You guys crack me up!!
Yeah - I'll post pics of the finished product, and you will see that looks had nothing to do with the loan! :)
I live in a small town - we don't have strangers here!

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:
