Deck coat application

I applied this product to our cottage deck on Friday and Saturday. The primer is like water and very messy to work with. The 5 gal pail of top coat was very thick and hard on the bottom of the pail,would not mix properly and ended up waiting acouple of inches on the bottom. With the amount of deck coat that I purchased I was hoping to get a 5th coat on, but didn't because I was short liquid from the big pail. The deck coat applied nice and looks good. Al

Seam tape

Easy to apply and put on, seems to work awesome!!! Pretty pricey and I didn't have enough even with the big roll to do my roof on a 22 foot rv camper. To be fair I didn't have a lot of seams on my tape but still. I just needed a couple more feet so that was bothersome and it was too late for me to try and order more. Time will tell if holds up but so far it's great and I'm really happy and dry.
