@spotiche5- Since painting a pool deck is a time-consuming, strenuous job that has to last, I would not recommend buying a bargain priced pain to do the work. After all, you will want to feel like your project is worth the effort when you are finished.
Keep in mind that not only is this not a task that you will want to repeat each year, but the paint must withstand the elements. Wind, rain, hail, sun, and snow all take their toll on even the best exterior paints. In addition, there will be a lot of wear and tear on your pool deck form all the people that enjoy it each season. These reasons are why you need to pick a top quality deck paint for your pool deck paint job.
