In my opinion, doing decks for well over 20 years: The short answer is no. Deckover, Deckcorrect, Deckrestore have many performance pitfalls. I’ll list them. Coating is too thick – If deck floor-boards are too close together these products will effectively close the gap between boards heightening the chances of trapping moisture causing wood-rot in the near future. Decks that are low to the ground, and  decks having an under-deck system will trap moisture causing deck floorboard rot, joist rot or a combination of both. Thick coatings might look good at first, but will more than likely peel. When they peel they become a nightmare to fix, sometimes requiring a floor replacement (very expensive), or having to sand off completely (expensive). Coatings like these mask rot until it is too late: Since these products are thick they don’t allow homeowners to see that wood is starting to rot until the damage is done. Costly – Product covers only 150 square foot per gallon requiring two coats. It is expensive- prohibitively so. My advice to someone who thinks their deck is in rough shape is to give a professional deck restoration company like ourselves a chance to refurbish their deck: Cleaning, sanding, sealing, or  use a solid color stain (2 coats) a quality solid color deck stain like Cabot solid stain, Flood-pro solid stain, or porch and patio stain like Benjamin Moore’s Porch & patio will not cause issues like these gimmicky quick-fix products do.
