Vinyl liners need not be resurfaced. In essence, they are thick plastic bags housed in a structure below the ground. However, most liners need to replace after a period of five to 9 years.
Of all these coatings, paint is the easiest and least expensive, but it also has the shortest lifespan—2-3 years for acrylic paint, 7-10 for epoxy, and somewhere in between the two for rubberized latex paint. Definitely DIY territory.
An aboveground pool is approximately $10 to repair (DIY tool) and about $1,700 in total replacement. For an average cost of $20 to patch an above-ground pool (DIY kit), and $5,000 to have it resurfaced if it hasn't been severely damaged, an inground swimming pool will cost you an average of $20. This cost can vary depending on which type of pool you have.
