High-traffic outdoor areas: For surfaces subject to frequent foot traffic and direct exposure to the elements-such as deck flooring or wooden walkways-a full recoating is required once a year before summer begins; any localized wear observed during routine use should be touched up promptly.
Vertical outdoor surfaces: For areas less exposed to rain runoff and lower-intensity sunlight-such as fences or exterior wall cladding-a complete maintenance treatment every 1.5 to 2 years is sufficient.
Humid indoor areas: For features like bathroom accents or sauna components, inspect and perform maintenance every 1 to 1.5 years; reapply the coating immediately if the surface loses its water-repellent properties.
Simple test method: Place a drop of water on the wood surface; if the droplet quickly soaks in and spreads, the protective layer has failed, and maintenance should be scheduled immediately.
