It was time to seal my concrete again. I had probably 4 gallons of a 5 gallon drum left over from the last sealing. So I used it and a 4 inch brush. I worked on it 3 different days before I ran out of sealer. Then I found out that they no longer sell the type sealer that I had. Several days of phone calls and a new 5 gallon bucket to finish the job. Whew am I happy that is over, it is one thing to paint a cement wall but entirely different to paint the ground. I think I am experiencing reverse evolution. I may never stand straight again.
