Suar wood is a striking tropical hardwood known for its dramatic grain, warm colour contrast and natural character. It is widely used for statement dining tables, live edge tables, coffee tables, shelves, benches, worktops, decorative panels and handcrafted furniture. Each slab has its own pattern, often with a darker heartwood centre and lighter outer sapwood, which makes suar timber a popular choice for people who want furniture with a unique, natural look.
Although suar wood is dense and durable, it still needs protection. Like all natural timber, it can absorb moisture, stain, fade, crack or become dull when exposed to everyday use, sunlight, spills or outdoor weather. Without the right treatment, a beautiful suar table can become marked by coffee, wine, grease, rainwater, UV exposure or dirt.

What is suar wood?
Suar wood, also known as Albizia saman, saman wood or rain tree wood, is a tropical hardwood commonly sourced from fast growing rain trees in regions such as Southeast Asia and parts of South America. It is especially popular for large single slab tables because the tree can produce wide boards with beautiful natural grain patterns.
Suar wood is known for:
- A warm brown to golden tone
- Strong contrast between heartwood and sapwood
- Distinctive grain movement
- Good density and strength
- A natural live edge appearance
- Suitability for large dining tables and coffee tables
- A handcrafted, organic look
- A smooth finish when properly prepared
Because of its appearance, suar wood is often used in high impact furniture pieces. A suar dining table can become the focal point of a room, while a live edge suar slab gives interiors a natural and premium feel.
However, suar remains a natural material. It reacts to moisture, sunlight, heat, spills and changes in humidity. That is why protection is essential. Want to learn more? Read our in-depth guide about how to make wood waterproof and water resistant.
Why suar wood needs treatment
Suar wood is durable, but it is not maintenance free. Its open grain and natural fibres can absorb liquids and dirt if the surface is left untreated. This is especially important for tables, where the surface is regularly exposed to food, drinks, heat, grease and cleaning products.
Untreated suar wood can suffer from:
- Staining from wine, coffee, oil and food
- Water rings and moisture marks
- Surface dullness
- Dirt trapped in the grain
- Greying from UV exposure
- Cracking or movement from humidity changes
- Mould risk in damp environments
- Weathering when used outdoors
- Loss of natural depth and colour
Treating suar wood helps preserve the rich colour and visible grain while improving resistance to everyday wear. A good protective coating also makes cleaning easier, because liquids and dirt are less likely to penetrate the timber.

Which suar wood materials can be treated?
NC Nano Wood Cleaner and NC Nano Coating for Wood can be used on many suitable suar wood and hardwood surfaces, provided the timber is clean, dry and suitable for treatment.
Common applications include:
- Suar dining tables
- Suar coffee tables
- Suar live edge slabs
- Suar desks and worktops
- Suar benches
- Suar shelving
- Suar decorative panels
- Indoor suar furniture
- Outdoor suar tables, where suitable
- Rain tree wood furniture
- Tropical hardwood furniture
- Similar hardwoods such as teak, acacia, oak and mahogany
Always test first on a small hidden area, especially if the wood has previously been oiled, waxed, varnished, stained, painted or treated with another finish.
Suar wood treatment for indoor use
Indoor suar wood is usually protected from rain, but it still faces daily risks. Dining tables and coffee tables are exposed to spills, fingerprints, grease, hot drinks, cleaning products and sunlight through windows.
For indoor suar wood, NC Nano Coating for Wood helps protect against:
- Coffee and tea stains
- Wine and juice spills
- Food grease and oil marks
- Water rings from glasses
- Dirt and hand marks
- UV related fading near windows
- Everyday surface contamination
Before coating, clean the surface with NC Nano Wood Cleaner. This ensures that grease, dust and old residues do not interfere with the protection. Once the timber is dry, apply NC Nano Coating for Wood evenly and allow it to cure fully before regular use.
The result is a protected surface that remains natural looking, tactile and easy to clean.
Suar wood treatment for outdoor use
Suar wood can be used outdoors in certain applications, but it needs extra protection. Outdoor timber is exposed to rain, damp air, UV rays, frost, temperature changes, algae and garden dirt. Without protection, suar wood can fade, grey, crack or absorb moisture.
For outdoor use, NC Nano Coating for Wood helps create a water repellent surface while allowing the timber to remain breathable. This is important because wood must be able to release internal moisture rather than trapping it beneath a sealed film.
Outdoor protection helps reduce:
- Rainwater absorption
- Greying from UV exposure
- Dirt build up
- Algae and mould conditions
- Weather related staining
- Cracking and surface movement
- Premature ageing
For outdoor suar furniture, always clean first with NC Nano Wood Cleaner, allow the wood to dry thoroughly and apply NC Nano Coating for Wood to all exposed surfaces where possible, including edges and end grain.
How to treat suar wood with nano coating
Treating suar wood is straightforward when the surface is properly prepared.
Follow this process:
-
Remove loose dust and debris
Use a soft cloth or brush to remove surface dust, crumbs and dirt. -
Clean with NC Nano Wood Cleaner
Apply NC Nano Wood Cleaner to remove grease, stains, dirt and old contamination. -
Allow the wood to dry fully
Do not apply coating to damp timber. The surface must be completely dry. -
Lightly smooth rough areas if needed
If the surface feels rough, lightly sand and remove all sanding dust before coating. -
Apply NC Nano Coating for Wood
Use a suitable applicator such as a cloth, brush, roller or low pressure sprayer, depending on the surface and product instructions. -
Work evenly with the grain
Apply a consistent layer across the table top, edges and live edge details. -
Remove excess product if required
Avoid leaving pools or uneven areas on the surface. -
Allow the coating to cure
Keep the wood away from moisture, spills and heavy use while the coating sets.
After treatment, water should bead more easily on the surface instead of soaking into the timber.
How nano coating works on suar wood
Nano coating protects wood differently from many traditional finishes. Instead of creating a thick surface film, NC Nano Coating for Wood forms a fine protective treatment that helps repel water and dirt while allowing the wood to breathe.
This makes it ideal for suar wood because it protects without covering the natural grain.
Main benefits include:
- Transparent protection
- Water repellent performance
- Reduced dirt adhesion
- Protection against staining
- Breathable finish
- No heavy gloss layer
- Preserves the natural texture
- Easier maintenance
- Suitable for indoor and outdoor use where appropriate
For suar wood, this is especially useful because the timber’s appearance is one of its main advantages. The coating helps protect the furniture while allowing the natural colour contrast and grain pattern to remain visible.
Suar wood coating versus oil, wax or varnish
Suar wood is often treated with oil, wax or varnish, but each option has limitations.
- Oil can deepen the colour and make the grain look richer. However, it usually needs regular reapplication and may not provide strong resistance against water marks, wine stains or outdoor moisture.
- Wax can give a soft and natural feel, but it is not ideal for high use tables or outdoor furniture. It can mark easily and may offer limited water resistance.
- Varnish creates a hard surface film. It can protect against spills, but it may look glossy, crack over time or hide some of the natural texture of the wood.
- NC Nano Coating for Wood offers a modern alternative. It provides transparent, breathable and water repellent protection without creating a heavy artificial layer. This makes it a strong choice for suar tables, live edge slabs and natural hardwood furniture.
Cleaning and maintaining suar wood
Even with a protective coating, good maintenance is important. Regular care helps keep suar wood looking clean, rich and natural.
Maintenance tips include:
- Wipe spills quickly
- Use coasters under glasses and mugs
- Use placemats for hot plates and serving dishes
- Clean with a soft damp cloth
- Avoid abrasive pads and steel wool
- Avoid harsh household chemicals
- Keep outdoor furniture ventilated
- Use breathable covers outdoors when needed
- Check water repellency periodically
- Reapply NC Nano Coating for Wood when water no longer beads well
For deeper cleaning, use NC Nano Wood Cleaner before refreshing the coating.
