Janka Hardness: Higher numbers = harder wood, more dent resistant

Understanding Janka Hardness

What it measures: Force (pounds) required to embed a 0.444" steel ball halfway into wood

Hardness Scale Reference:

  • <500: Very soft - dents/scratches easily (Cedar, Pine)
  • 500-900: Soft to medium - suitable for furniture (Cherry, Walnut)
  • 900-1500: Hard - good for flooring, heavy use (Oak, Maple, Ash)
  • 1500+: Very hard - excellent for high-traffic flooring (Hickory, Brazilian Cherry)

Application Guide:

  • Flooring: 1000+ recommended for durability
  • Furniture/Cabinets: 500-1200 range works well
  • Cutting boards: 900-1500 (hard enough, not too hard on knives)
  • Outdoor projects: Rot resistance matters more than hardness
Grain Porosity & Finishing Implications

Open-Grain Woods

Examples: Red Oak, Ash, Walnut

Characteristics: Large, visible pores

Finishing:

  • Use grain filler for smooth, glassy finish
  • Accepts stain very well
  • May require more finish coats to fill pores
  • Oil finishes soak in deeply

Closed-Grain (Tight-Grain) Woods

Examples: Maple, Cherry, White Oak

Characteristics: Small, tight pores

Finishing:

  • Naturally smooth surface
  • Difficult to stain evenly (especially Maple - use gel stain)
  • Clear finishes work beautifully
  • Requires less finish material
Optimal Finish Types by Wood

Oil Finish (Tung, Linseed, Danish Oil)

Best For: Walnut, Cherry, Teak, outdoor furniture

Pros: Easy application, enhances natural color, repairable

Cons: Less protective, requires reapplication

Gel Stain + Polyurethane

Best For: Maple, Pine, blotch-prone woods

Pros: Even color, highly protective topcoat

Cons: Can obscure grain slightly

Water-Based Stain + Poly

Best For: Oak, Ash (open-grain woods)

Pros: Penetrates well, low odor, fast drying

Cons: Raises grain, requires sanding between coats

Oil-Based Stain + Poly

Best For: Most hardwoods, traditional look

Pros: Deep color, long open time for blending

Cons: Slow drying, strong odor, yellows over time

Paint (Primer + Topcoat)

Best For: Pine, Poplar, MDF, utilitarian projects

Pros: Hides imperfections, unlimited color options

Cons: Completely obscures wood grain

Natural/No Finish

Best For: Cedar, Redwood outdoor projects

Pros: Zero maintenance initially, weathers beautifully

Cons: Will gray over time, no stain protection

Natural Rot Resistance

Excellent (Heartwood):

  • Cedar (Western Red, Eastern White)
  • Redwood
  • Cypress
  • White Oak (heartwood)
  • Teak (imported, expensive)
  • Ipe (tropical hardwood)

Moderate:

  • Douglas Fir
  • Southern Yellow Pine (pressure-treated exceeds this)
  • Cherry

Low (Not Outdoor Suitable):

  • Maple
  • Red Oak
  • Ash
  • Birch
  • Eastern White Pine

Note: "Heartwood" (inner, darker wood) is more rot-resistant than "sapwood" (outer, lighter wood). For outdoor projects, select heartwood or use pressure-treated lumber.

Wood Selection by Application

Flooring

Best: Red Oak, White Oak, Hard Maple, Hickory (Janka 1000+)

Why: Hardness resists dents, takes heavy traffic

Furniture (Fine)

Best: Walnut, Cherry, Maple, White Oak

Why: Beautiful grain, stable, workable

Cabinets

Best: Oak, Maple, Cherry, Birch

Why: Stable, accepts finishes well, affordable

Outdoor Decking

Best: Cedar, Redwood, Pressure-Treated Pine, Ipe

Why: Rot resistance, weather durability

Trim/Molding (Paint-Grade)

Best: Pine, Poplar, MDF

Why: Inexpensive, smooth surface, stable

Butcher Block/Cutting Boards

Best: Hard Maple, Cherry, Walnut

Why: Food-safe, hard but not too hard on knives

Framing/Construction

Best: Douglas Fir, Southern Yellow Pine, Spruce

Why: Strong, affordable, readily available

Common Finishing Mistakes by Wood Type

❌ Staining Maple without gel stain or conditioner

Result: Blotchy, uneven finish


❌ Using water-based finish on Cherry without UV protection

Result: Fades/changes color more than oil-based


❌ Not filling grain on Oak before gloss finish

Result: Pores visible, not smooth/glassy


❌ Using indoor-only finish on Cedar outdoors

Result: Finish fails, wood still weathers (use exterior oil or leave natural)

Additional Information

About This Wood Species Guide

This comprehensive wood species performance and finish guide helps woodworkers, furniture makers, and DIYers select the right wood for their projects and apply the best finish for each species. Understanding the characteristics of different woods - from hardness and grain pattern to rot resistance and finishing properties - is essential for achieving professional results.

The Janka hardness scale provides a standardized measure of wood density and dent resistance, helping you choose appropriate species for flooring, furniture, cutting boards, and other applications. Grain porosity affects how wood accepts stain and finish, with open-grain woods like oak requiring different techniques than closed-grain species like maple.

Whether you're building fine furniture from walnut, installing oak flooring, or constructing an outdoor deck from cedar, this guide provides the information you need to select the right wood and finish it properly for long-lasting, beautiful results.

Why Use This Wood Species Reference Guide?

Choosing the right wood and finish ensures your projects look beautiful and perform well for years. This guide helps you make informed decisions for any woodworking application.

  • Compare Janka hardness ratings to select wood appropriate for your application
  • Understand grain porosity and its impact on staining and finishing
  • Choose naturally rot-resistant species for outdoor projects
  • Select the optimal finish type for each wood species
  • Avoid common finishing mistakes that ruin project appearance
  • Match wood characteristics to specific applications like flooring, furniture, or decking
