    I use this sealer a good bit on different concrete jobs and I’m always happy with the results. It does take a long time to roll it on but worth it.

    U-Seal Concrete Sealer

    This Sealer is the absolute best in my opinion. I've been doing stone, tile and concrete for 30y years now and i've been through many many sealers. This product is easy to apply, give a great finish which still enhances the concrete look while creating a superior barrier to just about anything. Its worth the money and shipping (and I'm in Alaska) if you want to set it and forget it. I will not use anything else at this point. Fishtone has been a great company to work with for all my concrete needs. Super fast turn around on orders and great customer service. Thanks Guys\Gals! Nordic Construction.

    concrete sealer

    Very good seal layering, I have used others that went on too thick and then peeled because of that. This went on lightly, easily, and appropriately thin to allow coating without being too much and a future problem.
