Key Features to Consider When Shopping

When selecting an Olympic Wood Sealer, focus on coverage area, surface compatibility, and application method. All three products offer clear finishes to preserve wood grain, but they differ in concentration and intended use:

  • Multi-Surface Compatibility: The Waterguard Multi-Surface and Stain Smartguard handle wood, concrete, and masonry, perfect for mixed-material projects.
  • Concentrated Formulas: Smartguard's 15oz bottle expands to cover more area, ideal for spot treatments or smaller jobs.
  • Exterior Durability: WaterGuard Exterior excels on bare or weathered wood, repelling water for up to 6 years on decks.
  • Easy Application: All apply with brush, roller, or sprayer; no primer needed on most surfaces.

Look for mildew resistance and UV protection to extend wood life in harsh climates. These features make Olympic a go-to within Paint, Wall Treatments & Supplies.
