For exterior wood, the right finish depends on where it will be used and how much grain should show. Sherwin-Williams groups stain choices from clear through semi-transparent to solid: clear shows more grain but offers the least UV protection, while solid color stain hides grain and leaves texture visible. Match the exact finish to a deck, siding or fence, then follow its preparation and maintenance directions.
Choose an exterior finish by surface, existing coating and the amount of wood grain you want to see. A vertical siding product, fence coating and deck finish can have different approved uses even when the colors look similar.
Compare the finish by opacity
| Finish | Appearance and buyer check |
|---|---|
| Clear or toner | Shows most natural grain and color. Sherwin-Williams’ deck guide says clear stain provides the least UV protection; review the exact label and renewal instructions. |
| Semi-transparent | Leaves grain visible under added color. Confirm approval for the wood species and the specific deck or siding surface. |
| Solid color stain | Hides grain while leaving wood texture visible. Compare it with paint for the desired opaque look and check the approved surface list. |
| Exterior paint | Provides a more uniform, opaque color. Match primer, topcoat, substrate and exposure to the paint maker’s system instructions. |
Sherwin-Williams describes these stain opacities in its deck-planning guide and staining FAQs. Product lines differ, so use the exact finish documentation for the project.
Match the coating to the surface
- Deck boards: Select a finish marked for horizontal walking surfaces. Check foot-traffic use, cleaning steps, drying conditions, coat count and maintenance in the chosen product sheet.
- Siding and trim: Compare the finish with the wood condition and the existing coating. A semi-transparent stain keeps more grain visible; solid stain and paint give a more uniform color.
- Fences: Consider whether you want the grain to remain visible and whether the chosen finish is approved for the fence’s species and existing treatment.
The wood itself can decide the project. Sherwin-Williams says severely soft or cracked, cupped wood may need replacement before staining. Include any repair, cleaning and coating removal in the written scope, and test the finish on a small area before buying material for the whole surface.
Compare bids and product instructions
Ask each contractor to identify the exact coating, primer where required, surface preparation, number of coats, drying conditions and care directions. State whether the surface is bare, previously stained, painted or composite. Follow the current manufacturer’s instructions for that exact product and substrate.
For the deck surface underneath the finish, compare composite, PVC and wood decking. For a nearby wood boundary project, see wood, vinyl and aluminum fences. Use the remodeling contractor checklist to compare preparation and labor in itemized bids.

Common questions
Is deck stain better than exterior paint?
It depends on the surface and finish you want. Choose a coating whose label approves it for the exact wood and exposure, then compare preparation and maintenance instructions.
Which stain shows the wood grain?
Clear and semi-transparent stains show more grain than solid color stain. Exact appearance and protection vary by product, so review the product sheet and sample on the same wood.
Can I stain over a painted deck?
The existing coating affects preparation and compatibility. Identify the paint, review the stain maker's removal and surface-preparation instructions, and include the work in the project quote.
Can I use siding paint on deck boards?
Use a finish specifically approved for the deck's walking surface. Exterior paints and stains have different approved uses, and product instructions set the right preparation and application.
