There is nothing between the sheets on the block. I have never had a problem with the sheet below getting damaged from water on the top sheet.
As mentioned you will see that there is a little space where the sheets are not sealed and that is where you would insert the knife blade and then slide it all the way arount the sheet. I have found that if I just start it part way and just pull the paper off sometimes I have damaged my paiting.
I have never put tape over the edge but I could see that if you used a LOT of water that would prevent bleed.
Pads are a great way have paper ready to go and you can always find them on sale someplace.
Good Luck
