I used this to add protection to an old concrete stoop that has a lot of aggregate exposed. It's 4' wide and has about 4 steps including an upper and lower landing. After thoroughly cleaning the dirt and plant matter from the concrete. I applied this the following day using a standard nap roller from the dollar store. My first time ever doing this type of work. I may have applied it too thick because it was very puddled all over. I tried to sop excess up with the roller after second coat with mediocre success. Needless to say this dried very well overnight. No shine. I checked on it after a day of long hard rain and the surface still looked great. It was easy to blow fallen plant matter and leaves off leaving no stains on the concrete. Hoping this will also help protect from salt in winter. I used a little more than half gallon but I did overapply the product. Forgot to get before pics but huge improvement. Water beads on the surface now.
