1. What do you guys put under the compactor when you guys are compacting the pavers? I'm reading that you guys purchase or have the option of putting a rubber mat under the compactor and run it over the pavers so it has a less chance of scuffing? This seems like a [pretty good idea to me, but what kind of rubber mat are we talking about here? What several other options are available to this ? 2. What do you guys use to seal the pavers and when would you use it? Would you use the sealant right after you install the pavers? I heard that if you do, you will be sealing in the efflorence, should you wait 6 months before you go back and seal it?
