It covers about 350 square feet per gallon, which is typical for siding treatments.

Applying Vinyl Renu is straightforward: after cleaning and drying the siding, you simply brush or spray it on. Since it’s clear and doesn’t require sanding or priming, the process is less messy and time-consuming than repainting.

Compatibility is broad — it works on vinyl, metal, Hardie siding, doors, and even outdoor furniture. However, it’s not recommended for white siding since it doesn’t enhance color there.
