1. ZAR® Deck & Siding Semi-Transparent Stain
ZAR® Semi Transparent Deck Stain & Siding | Various Colors
Best for: Homeowners who want a natural look that enhances the wood grain while providing UV protection and water resistance.
This traditional oil-based semi-transparent stain penetrates deep into the wood, enriching the natural tones while protecting against the elements. It allows the wood’s grain and texture to show through, creating a rich, warm, durable, and beautiful finish.
Use it when:
- You’re working with new or bare wood, especially cedar, redwood, or pressure-treated pine.
- You want a warm, stained look that highlights the wood’s character.
- Your deck or siding gets partial sun exposure and you’re okay with reapplying every 2 – 3 years for upkeep.
Pro tip: Ideal for vertical surfaces like siding or fencing but can also be used on decks for a traditional, timeless finish.
2. ZAR® Deck & Siding Solid Color Coating
ZAR® Deck & Siding Solid Color Coating
Best for: Maximum protection with bold, uniform color. It completely hides the wood grain.
This product is designed for tougher jobs and older wood. It provides a thick, protective barrier against harsh weather, UV rays, and foot traffic. Perfect for revitalizing aged decks or siding with a fresh, vibrant look.
Use it when:
- Your wood is weathered, uneven in tone, or previously painted/stained.
- You want a longer-lasting, opaque finish that resists fading and peeling.
- The surface is heavily exposed to sunlight and moisture.
Pro tip: This product offers the highest durability — perfect for older decks or high-traffic areas. It can be tinted to a wide range of custom colors.
3. ZAR® Deck & Siding Clear Waterproof Wood Sealer
ZAR® Deck & Siding Clear Waterproof Wood Sealer
Best for: Preserving a natural, untreated wood appearance while offering water repellency.
This clear sealer is ideal when you want the wood to speak for itself. It doesn’t darken or enhance the wood — it simply seals it against water intrusion.
Use it when:
- You love the raw look of natural wood and want to keep it as is.
- Your surface need minimal UV protection (e.g., shaded porches or fences).
- You’re okay with annual reapplication for the best performance.
Pro tip: Not a stain — it won’t alter or enhance color. Use it on newer wood for a clean, minimalist aesthetic.
4. ZAR® NuDeck® Wood & Concrete Resurfacer
ZAR® NuDECK®: Wood & Concrete Water Based Restorative Coating
Best for: Extending the life of worn wood or concrete surfaces with a textured, slip-resistant finish.
NuDeck® is the heavy-duty solution for surfaces that are splintered, cracked, or peeling. It fills in small cracks and provides a solid, durable coating that withstands foot traffic, UV rays, and moisture. It’s also suitable for concrete patios or walkways.
Use it when:
- You’re dealing with splintered or deteriorating deck boards that aren’t ready to be replaced.
- You need to rejuvenate old concrete or heavily worn surfaces.
- You want a slip-resistant, durable finish for added safety.
Pro tip: Apply with a textured roller for best results. This is not a stain or sealer — it’s a resurfacing solution that builds a new protective layer.
