Buying Guide

  1. Moisture Content and Stability — Kiln drying reduces moisture, minimizing warping and cupping. Look for boards explicitly labeled kiln dried for outdoor use to improve stability over time.
  2. Species and Finish — Teak offers natural oil resistance and premium looks but can be heavier and costlier. Maple and Ash provide strength with lighter tones. Black Limba adds creative variety but may require schedule-driven finishing choices.
  3. Dimensional Accuracy — Consider how actual thickness and width align with your project plans. Some boards are nominal and may be slightly thinner than listed.
  4. Board Lengths — Longer boards reduce seam lines and improve surface continuity but may be harder to handle. Choose lengths based on deck span and layout.
  5. — Determine if you need pre-surfaced (S2S) boards or if you will plane and sand yourself. S2S boards save time but still require exposure to finish for outdoor use.
  6. — For outdoor decks, ensure you select boards compatible with your fasteners and joists, and plan for sealing or oiling per species recommendations.
  7. Budget and Aesthetics — Teak offers premium aesthetics and durability but at a higher cost. Hard Maple and Ash provide solid performance with more affordable options.

Frequently Asked Questions

What does kiln dried mean for decking boards?
Kiln drying reduces moisture content, increasing dimensional stability and reducing the chance of warping after installation.
Are teak boards suitable for outdoor use?
Yes. Teak natural oils and dense grain make it highly resistant to moisture and decay, ideal for outdoor decks with a premium look.
Should I choose thicker boards for a stronger deck?
Thicker boards can offer added strength and fewer flex points, but installation methods and joist spacing must be adjusted accordingly.
What is S2S in lumber terms?
Sur faced-2-sides; both faces are surfaced smooth, reducing prep time for final finishing.
Is it better to buy longer boards?
Longer boards reduce visible seams, but they require more handling and precise cutting. Match lengths to deck layout.
Can I mix different species on the same deck?
Yes, but consider color, grain, and hardness differences. Plan toppers or borders to accommodate transitions.
