Ghostshield: Polyaspartic 745 (Countertop)

When I applied the 745 there are some spots where it is not very smooth. Can I do a light sand and put a second coat on?

Yes

Does this yellow over white paint?

This should not be used over paint.  This adheres directly to the concrete

Can this go over painted granite counter? If not can it be tinted with mica powder?

We do not reccomend using this over a painted surface.

Will this work on exterior concrete countertops?

This is recommended for indoor use only

I have a product called Shiretone countertops that were installed years ago. Their polyurethane finished that come with the Shirestone countertops is now dulling. I was wondering if this prouct could be installed direction over that to bring back it's shine.

I would suggest removing the existing finish to prevent possible issues with the polyaspartic adhering. It is to go directly on to concrete.

Can I use this on painted Formica countertops to give them gloss and protection?

It's made to bond to concrete, but you can get a sample and try it out!

Can I resurface with this sealer over polyaspartic polyura itself? What chemical will remove the old polyaspartic polyura?

This can be used to recoat over existing polyaspartic if it is clean. Xylene should soften the existing coating for removal if you wish to go that route

Do you have a concrete countertop sealer that provides a wet look when it is dry?

The 745 will give you the highest gloss

I painted graphics on my concrete counter tops. Will this product cause the underlying paint to lift?

You shouldnt have any issues with the polyaspartic lifting the paint, however, with all instance, not knowing what type of paint, the condition of the surface, we reccomend testing a small area first.

I used ghostshield 745 on my concrete bar top and it turned out great, my question is what should I use to polish it?(to remove fingerprints and such). Thanks

You shouldnt need to polish the 745 as it is a chemical reisistant, durable coating.  It can be cleaned with any household cleaner to remove finger prints etc.

Can color be added, such as a marbling effect? If yes, what is used?

No, there is not a color option for the Polyaspartic.  You can check out the Urethane 645 which has color options.

Will this work on my epoxy countertops in my kitchen?

If you have epoxy, I would suggest a urethane stealer vs polyaspartic.  Ghostshield: Urethane 645

When is sealer applied? We are finishing our countertops today and wondered how long we needed to wait before sealing?

You would want to wait until the concrete is cured to apply the sealer.  Roughly 8 days.

Will this darken the concrete? Also do you have to put something else on the concrete before applying such as a primer?

This product may make the concrete appear slightly darker, just due to the nature of a high gloss finish, but wont look like the concrete is wet.
