We need to make some repairs to our pool and would love some suggestion on the best products to use to: (1) Fill the expansion joint - we used Deck o Seal last time, but I'm a bit older now so squeezing that bottle gets tough; (2) Fix some areas of broken or cracked brick coping; (3) resetting several tiles; and (4) filling in at the top of the tile line where the old grout has eroded a bit over the years. Thanks.
