Concrete Driveway Sealer Video

i have approx. 5500 sq. ft. of concrete. its about 1 yr old. a sealer was put on it after it was poured, but the surface seems to absorb water. i am considering using a penetrating sealer on it but i am concerned about the original sealer. do i need to make sure the old sealer is off? if so how do i remove it? i have a 2500 psi pressurer washer, will that do the trick? i need your advise. also can you recommend a good sealer? i've seen some that say you only have to apply it 1 time and never again, is this true?
I NEED YOUR ADVISE!!! THANKS, JOHN

Without knowing what sealer was used the first time, it is impossible to be certain about removal. It is my feeling that if water is easily flowing down into the slab, the sealer is not doing its job and a penetrating sealer will be able to flow down into the slab and get the job done!

There are a few different penetrating sealers out there, and after a lot of research I believe the silicate reactive sealers are going to protect better than any other type. They are waterborne, colorless, penetrate deep into the slab and fill the pores completely while allowing the concrete to breathe. Salt, water and ice will no longer be a problem at the surface or deep inside.
