The pictures above are of a deck I refurbished this past summer and was one of best works of the summer. At the beginning, the deck was in really bad shape and needed a lot of work done to make it a good looking, functional deck. I ended up stripping the wood back down to its original wood polish so i can pretty much start with a clean slate product. After that, I sanded the whole deck, from railings to floor to siding. That took me about two days worth of work. After every piece of wood was sanded and prepped, I started staining the railing with a brush and then moved to the outside of the deck. I rolled stained the flooring of the deck just like you would a wall in a house. This creates an evenly amount of stain to be distributed among the whole floor giving it the same look from one end to the other. After the stain sat for about a day and dried completely, I sprayed a layer of sealant on top of the stain to protect it from wearing out too soon and allowing it to last longer without fading. A lot of people don't do this when redoing their deck because you don't really have to, but I prefer it because it allows the product to have outstanding quality and with outstanding quality comes a happy customer.
This deck only took me about a week to finish and I really love the color and the final product I made. The customer was extremely happy and ended up inviting me to a cookout she had the following week to show to it off to her friends and family.
This is something that I really like to do and I have been able to succeed in doing so, however, people don't want their decks to be redone all year round so its a seasonal job.
I also refurbished a few garage floors over the summer as well but I don't have any pictures to promote and show that aspect of what I can do.
