Oil teak or let it go gray?

Both fine. Oiling maintains color but requires maintenance. Gray is maintenance-free and harmless.

Finishing teak is optional but preserves its warm honey-gold color rather than allowing it to weather to silver-gray.

Ring-porous with medium pores.

Wood Characteristics

Straight, sometimes wavy grain with slightly coarse texture. Ring-porous with medium pores. 1070 Janka. Golden honey-brown with darker streaks. Moderate tannin but very high natural oil and rubber content.

Recommended Finishes

Teak oil (specifically formulated); tung oil for natural matte; marine-grade spar varnish for boats; hardwax oil for indoor teak furniture.

Preparation Steps

Sand with 120-180 grit. Wipe with acetone or lacquer thinner to remove excess oils. Allow solvent to evaporate 30 min. For weathered teak, use two-part cleaner before refinishing.

Application Steps

1. Clean with acetone. 2. Apply teak oil with cloth or brush. 3. Soak 15-20 min. 4. Wipe off all excess. 5. Dry 24 hours. 6. Apply 2-3 coats with 320 grit sanding between. 7. Marine varnish: 6-8 thin coats, sanding between.

Maintenance Schedule

Teak oil: reapply every 3-4 months outdoors, 6-12 months indoors. Marine varnish: recoat annually. Unfinished: clean with teak cleaner annually.

Common Mistakes

Varnish too thick on boats causes bubbling; not removing surface oil before finishing; generic deck oil instead of teak-specific products; over-oiling creates sticky dirt-attracting surface.

Interior vs Exterior

Interior: Beautiful furniture and countertops. Hardwax oil or tung oil brings out golden warmth. Exterior: Ultimate outdoor wood. Oil to maintain color or leave natural for silver patina. Both valid.
