Im preparing to demold my countertops and I am trying to decide on a sealer so I can decide on how high of a grit to polish my tops with. I'm between surecrete xs327 and nanocoat tk6. I'd like something with a high gloss. Everything I'm reading says to polish to about 1500 grit but I don't want to polish so high that these sealers dont adhere. Any advice is appreciated.
Thank you.

Sealer choice can evoke a lot of emotion in this industry.  there isn't a bullet proof sealer.

I personally would recommend U-Seal as it has been showing the best results with the fewest call backs.  It has similar end resulting performance compared to the XS-327 but it applies  much easier and re-coat time is much faster as it doesn't require humidity to cure.  It comes in a matte/satin finish but you can easily get a gloss finish by only allowing the sealer to induct for 10 minutes (not the 30 minutes the instructions say).  

If your going with the U-Seal or the TK6 you should polish no higher than 400grit.  Going higher will not help with the shine/gloss of the concrete as the sealer will dictate that.

Here is a ling to U-Seal where you can also find a good application video... http://www.concretecountertopsupply.com/Item/U-Seal_Concrete_Counte...

I'll look into this. Thanks again for all your help.

If you read the Tech Data sheets for the XS-327 and the TK6 sealer they both suggest that you polish only up to 400 grit.

Having used the gloss in the XS-327 and TK6 neither really give "high" gloss. To achieve a higher gloss with these sealers you can use diamond infused dry burnishing pad once the sealer is fully cured. This will bring out more of a shine/reflection in the surface. 

Thanks. Can you recommend anything that will give a high gloss? I just want to make sure I have my sealer chosen before I polish so I know how high to go.

Thanks. I guess if I used something like that I'd have to go to a different sealer. Just another question and for the sake of not making another thread. I used Cheng pro formula in charcoal to cast my tops. I haven't seen them yet but should I decide that I want a deeper black can I stain prior to sealing?
I had reached out to surecrete about their xs327. They got back to me and said that after sealing I can continue up to a 1500 grit and the bring back the shine by buffing and waxing. Would I do this with the wet polisher? Seems to be a hassle to go this route. I'll be doing my wet polishing outdoors then I'll bring them inside and wait the recommended time before sealing. I'd hate to then bring them outside to wet polish once again after sealing.
If this is glossy enough, this is Trinic's SB Sealer. It takes practice to get it on (wiping on thin coats with a microfiber cloth without wipe lines). But there are no other steps besides polishing it to a mirror shine if you'd like.

Hi Jon,

U-Seal is both gloss and low gloss.  It all depends on the time you allow to induct.  After mixing parts A&B you will need to allow the sealer to induct.  If you only wait 10 minutes you will get a glossy surface and if you wait 30 minutes you will get a low gloss finish.  You can also buff U-Seal with Polyblue polising pads to bring up shine.

Based on your suggestion I think I'm going to try the useal. Being a beginner I like that it's easier to apply than xs327. A couple questions. I currently have the countertops in my garage where I've just finished polishing to 400 grit. I'd like to continue wet polishing after sealing but my weather has been mid sixties during the day and low 40s at night. Garage is unheated and uninsulated. Is that too cold for application? It so I will seal them indoors but I don't want to have to bring them back out to resume polishing. In that case will I get as good results by dry burnishing indoors? Also what should I clean the concrete with?

Why are you wet polishing after sealing?...there is no need to do that.

I would suggest sealing in 60 degrees or higher.  Anything colder may delay the cure
