Teak Outdoor Furniture: How to Buy It and Care for It

Why teak works by the sea

Teak (Tectona grandis) is a tropical hardwood rich in natural oils and resins. They make the wood resistant to water, rot and insects, keep it stable as humidity changes, and leave it smooth rather than splintery after years outside. That is why teak was used on ship decks long before it reached the patio, and why it suits a terrace that gets salt spray.

Teak does not need a finish to survive outdoors; a finish only changes how it looks. The furniture maker Westminster Teak puts it plainly: natural teak will last a lifetime untreated and weathered, and a finish is entirely a matter of preference.

Grade A, B, C: what the labels mean

Almost every teak seller talks about grades, and most describe them roughly like this:

• Grade A: heartwood from the center of a mature trunk – dense, oily, an even golden brown with tight grain.
• Grade B: outer heartwood – lighter and less even in color, with less oil.
• Grade C: sapwood from the outside of the trunk – pale, patchy and low in oil, so it weathers and wears faster.

The catch: as far as we could find, these letters are not a formal, standardized grade. On the retailer pages we read, “Grade A” appears as a product label without a definition, and none of them named a standard or an independent body that assigns it. One seller's A can be another's B. Treat the letter as a description, not a guarantee, and ask the questions that matter:

• Is every part solid heartwood – legs and slats included?
• Where does the wood come from, and is it certified (FSC, for example) or plantation-grown with a named source?
• Was it kiln-dried? Properly dried wood moves and cracks less.
• Do the photos show the grain and color on every part? Pale streaks and white patches are sapwood.

Plantation or reclaimed teak?

Most new teak furniture is made from plantation teak, grown in managed forests in the tropics – Indonesia is a well-known source. Look for a certification you can check, such as FSC, and for a seller who says where the wood comes from. Young, fast-grown trees contain more sapwood and less of the dense, oily heartwood, which is one reason quality varies.

Reclaimed teak comes from old buildings, boats and furniture. It is often old wood with plenty of character – nail holes, saw marks, varied color – and it gives timber a second life. The trade-off is consistency: pieces differ, so check that the wood is solid and properly joined rather than patched together.

Construction: joinery, thickness, stainless-steel hardware

• Joints: look for mortise-and-tenon joints, glued and pinned with teak dowels, at the main load points. Screws alone loosen over time.
• Thickness: legs, rails and slats should look substantial rather than skinny; thin parts warp and break first.
• Hardware: stainless steel or brass only. Plated steel rusts in salt air and leaves dark stains on the wood.
• Finish: surfaces sanded smooth, slats evenly spaced so water runs off, no gaps at the joints.
• Weight: dense teak is heavy. A chair that feels light for its size may be sapwood – or a different wood.

Golden or silver: sealing vs. letting it weather

New teak is honey-colored. Outside, sun and rain gradually turn the surface a soft silver gray. This patina is only skin-deep – the wood underneath is unchanged – and many people prefer the weathered look by the sea.

Westminster Teak, which sells Golden Care products, says the water-based protector keeps teak's original color up to four times longer than untreated wood and lasts about six months to two years outdoors, depending on exposure. On a dining table, Golden Care's Teak Shield goes on top as a water-based barrier against food and drink stains. Don't seal teak that has already turned gray or that was oiled: clean it back first, then protect it.

Care: cleaning, sealing and winter storage

1. Clean once a year

   Wash with mild soap, water and a soft brush, working with the grain. For gray or blotchy teak, use a teak cleaner: Golden Care's goes on wet wood, sits for about three minutes, is scrubbed with the grain and rinsed off. Wear gloves and eye protection, and cover the ground underneath.

2. Sand if needed

   If the cleaned surface feels rough, sand lightly by hand and remove all the dust.

3. Let it dry completely

   Sealing damp wood traps moisture. New teak should weather for a week or two, or be cleaned, before the first coat of protector.

4. Seal, if you want it golden

   Shake and stir the protector well, test it on a hidden spot and apply thin, even coats, with a second coat once the first has dried.

5. Cover or store for winter

   Teak can stay out, but it stays cleaner under a breathable cover or in a dry shed. Avoid wrapping it in plastic sheeting, which traps condensation.

Teak vs. acacia, eucalyptus and recycled plastic

If you want the look of teak without the care, teak-colored recycled plastic is the practical choice – our Adirondack chair guide has examples. On a tight budget, acacia gives the warm wood look as long as you oil it and bring it in for winter.

Where to buy teak outdoor furniture

Larger teak pieces and dining sets are mostly sold by specialist teak retailers and furniture stores rather than on Amazon. Specialists tend to state origin, drying and construction in more detail and can supply replacement parts – put the questions from the grade section to them before you order. Amazon is useful for care products such as cleaners and protectors.

Plan the space before you buy: a teak dining set wants room for the chairs to slide back and, by the Mediterranean, a little shade. Our coastal patio ideas help with the layout, and once the table is set, try whole fish, Andalusian espeto style. More pieces are in the coastal furniture section, and the modern coastal style guide shows how teak fits indoors too.
