Spa and hot tub covers are made of marine vinyl and will begin to desiccate (dry out) after one season of summer sun and winter weather. Conditioners will keep the vinyl from drying out, but only pigmented finish will act as a durable sunscreen. Cracks and tears need to be addressed promptly before the entire cover loses structural integrity or becomes cost-prohibitive to repair.
This picture from 2004 shows our anti-UV conditioning stain applied to Rebecca’s spa cover.
Twelve years later the cover was water-logged. Rebecca found a used cover and swapped the foam inserts. The vinyl on the used cover was years younger, but Rebecca’s, despite years of blistering Southern California sun and torrential rainstorms, was in better condition thanks to a one-time application of 3-4 coats of Rub ’n Restore®. Thus, we can guarantee that our finishes will double or triple the life of marine vinyl on hot tub covers. Colors containing white (titanium oxide) act as an especially potent sunscreen.
Our Ivory, Beige, Taupe, Camel, Walnut, Slate, Ash, Storm Blue, Midnight Blue, Forest, and Rust colors were all modeled after common marine vinyl colors used to make spa covers. Use a glaze (mix of equal parts color and Clear Prep+Finish™) as a primer or first coat. This will disperse better on weathered vinyl and ultimately cost less than using color alone. Here’s how to estimate quantity needed.
All this said, Rub ‘n Restore® cannot reverse damage (i.e. waterproof a leaky cover), nor is it a void filler. The sun-rotted marine vinyl pictured above benefited from four coats of our anti-UV finish, but anything worse requires a proper vinyl repair putty like our Soft Filler. This, however, is cost prohibitive for large areas of degradation.
Vinyl with extensive cracking, scaliness or flaking is best resurfaced with Liquid Rubber® RV Roof Coating. We used it on both the hot tub cover pictured above and a sun-rotted yurt roof with great success, thanks in part to knowledgeable tech support from the company itself. Currently it is only available in white. It can be tinted with universal colorant and diluted with water. Rub ‘n Restore® leather and vinyl colors can be used on top of Liquid Rubber® to achieve the desired color.
If and when you spring for a new spa cover, be sure to protect it with Rub ‘n Restore® before the second summer comes ’round. You’ll only have to deal with eventual water-logging, not disintegrating vinyl. We’ve even had customers use it on vinyl siding!
