Ghostshield: Lithi-Tek 4500 Concrete Sealer/Densifier

4500 and 8510

I applied the 4500 one week ago and the 8510 in two coats today, wet on wet. since i was covering a rock water fall into a spa with a basin above the water fall, the process was very tedious and had to be done with a brush. Both were very easy to use and the seller provided great guidance on application. I will turn the water fall on this Saturday. JIM
