Any recommendations for a paver sealer need to know condition and situation of your the patio.

The condition is good. It was installed a couple of years ago. I am looking for a clear sealer that will help keep them from getting dirty and stop growth (fungus, etc.). The only thing I can find at the box stores was Thompsons all purpose sealer. What type of stores would sell sealer?

Top of the line Prosoco penetrating sealer - $$$
Very good quality Miracle 511. - $$

No sealer will keep fungus growing if the area is the perfect storm of light and moisture - but the sealer will make cleaning the fungus off easier .

Buy anything but Thompson's. :-P
