Easy to use and works

Worked great on my 3000 grit polished concrete countertops.

Surprised it did not have a spritzer with it. I know it didn't have one in the picture but II thought it was just a mistake. The product went on easy enough and time will tell how effective it is.

I used this sealer for my DIY councrete countertop. It will slightly darken the surface from the untreated color. To give you an idea of the finished color, it’s about halfway between the untreated color and when it’s soaked with water.It has good water repellent properties however water sitting will be absorbed over time, you should clean spills ASAP, this product is not miracle, it only buys you time.I put 8 coats and let dry at least 2h between each. I used a small foam roller to apply and it worked quite well. Keep it wet for 5 minutes and wipe excess with dry cloth. Follow directions and don’t let product dry or sit on the surface.If using on concrete, you better finish it with beeswax for additional protection.

This is the best granite sealer I've ever used. Gets into the pores of the granite as well as little nicks and scratches in the granite so that, when you run your fingers over it, it feels perfectly smooth with no indication that there were ever any nicks.
