Clear sealer
A clear or lightly tinted water repellent preserves the natural look but provides limited UV protection. It may suit newer attractive wood when frequent maintenance is acceptable.
Semi-transparent stain
Semi-transparent stain adds color and UV protection while keeping some grain visible. It needs evenly prepared, absorbent wood; leftover film or patchy weathering can create uneven color.
Solid-color stain
Solid stain hides more variation and is often used on older or previously coated decks. It forms more of a film, so peeling edges and trapped moisture must be addressed.
Dry wood matters
After Indiana rain or washing, shaded boards can remain damp below the surface. Moisture should be checked before application rather than judged by appearance alone.
Maintenance expectations
Horizontal boards weather faster than vertical rails and fences. Sun, standing water, snow, shade, and foot traffic shorten service life, especially where end grain and board gaps stay wet.
