Massaranduba Deck Maintenance Guide
Everything you need to clean, protect, and maintain Massaranduba (Brazilian Redwood) decking — weathering behavior, oil frequency, cleaning, color restoration, and species-specific care tips.
Janka Hardness
3,190 lbf
Lifespan
40–60+ years
Density
Very high (67 lbs/ft³)
Oil Frequency
Once per year
How Massaranduba Decking Weathers
Natural Color
Deep reddish-brown to burgundy
Weathered Color
Dark gray
Weathering Speed
Slow to moderate — similar to Ipe. Massaranduba's density helps it resist UV change, though its deep red color shifts noticeably.
Color Change Detail
Massaranduba fades from deep reddish-brown to a darker gray than most species. The red undertones gradually mute but remain slightly visible even after years of weathering.
Cleaning a Massaranduba Deck
Massaranduba cleans similarly to Ipe — its density keeps dirt on the surface. A standard deck cleaner and soft brush work well.
Recommended Cleaning Steps
Clear furniture and debris. Sweep thoroughly.
Apply a tropical hardwood cleaner (DeckWise Hardwood Deck Cleaner, Messmers Deck Cleaner, or Penofin Pro-Tech Cleaner).
Scrub with a soft-bristled brush in circular motions. Focus on trouble spots.
Rinse thoroughly with a garden hose. Allow to dry completely before any treatment.
For stubborn stains, use Savogran TSP Eco Cleaner. Avoid household bleach on Massaranduba.
How Often to Oil Massaranduba Decking
Oil Frequency
Once per year. Massaranduba holds its oil well due to density, and annual treatment is sufficient in most climates.
Oil Absorption for Massaranduba
Slow — like Ipe, Massaranduba's high density means oil absorption is slow. Thin coats and prompt excess removal are critical.
Recommended UV Oils for Massaranduba

Massaranduba Tannin Bleeding & Runoff
Tannin Level
Moderate to high initially. Massaranduba can produce reddish tannin runoff that's quite visible on light surfaces during the first months.
Red tannin from Massaranduba is among the most visible of tropical hardwoods. Pre-sealing or a drip barrier is recommended above light surfaces.
Restoring Weathered Massaranduba
Restoration reveals Massaranduba's stunning burgundy color. Sand with 60–80 grit and apply oil immediately. The restored color is among the most dramatic of any tropical hardwood.
Massaranduba Maintenance Tips
Massaranduba's red tannins are highly visible — protect adjacent light surfaces during the first 3 months.
Thin oil coats only — its density rivals Ipe and won't absorb heavy applications.
The restored color after sanding is stunning — burgundy tones return dramatically.
End-seal all cuts to prevent checking (same requirement as Ipe).
Annual oiling preserves the rich reddish tone that distinguishes Massaranduba from other species.
Common Massaranduba Maintenance Mistakes
Ignoring tannin bleed potential — Massaranduba's red runoff is very visible on concrete.
Over-applying oil — same as Ipe, thick coats create a sticky surface.
Expecting the red color to persist without UV protection — it fades to dark gray like all untreated hardwoods.
Pressure Washing Massaranduba
We do not recommend pressure washing Massaranduba unless absolutely necessary and you have experience. Keep pressure below 1200 psi, use a wide spray pattern, and never hold in one spot.

Massaranduba Maintenance FAQ
Common questions about maintaining Massaranduba decking.
Once per year. Massaranduba holds its oil well due to density, and annual treatment is sufficient in most climates.
Massaranduba naturally transitions from Deep reddish-brown to burgundy to Dark gray when left untreated. Slow to moderate — similar to Ipe. Massaranduba's density helps it resist UV change, though its deep red color shifts noticeably. This is purely cosmetic — the wood remains structurally sound for 40–60+ years.
Massaranduba cleans similarly to Ipe — its density keeps dirt on the surface. A standard deck cleaner and soft brush work well. Use a tropical hardwood-approved cleaner such as DeckWise Hardwood Deck Cleaner or Messmers Deck Cleaner. Avoid harsh chemicals and keep pressure washing below 1200 psi if needed.
Restoration reveals Massaranduba's stunning burgundy color. Sand with 60–80 grit and apply oil immediately. The restored color is among the most dramatic of any tropical hardwood.
Sealing is optional but recommended. Massaranduba won't rot or decay without sealing, but UV oil or sealer preserves the deep reddish-brown to burgundy color. Without treatment, Massaranduba weathers to dark gray.
Moderate to high initially. Massaranduba can produce reddish tannin runoff that's quite visible on light surfaces during the first months.. Red tannin from Massaranduba is among the most visible of tropical hardwoods. Pre-sealing or a drip barrier is recommended above light surfaces.
Use oil-based penetrating sealers designed for tropical hardwoods: Messmers UV Plus for Hardwood, Ipe Oil by DeckWise, or Penofin Exotic Hardwood Formula. Avoid film-forming finishes (polyurethane, lacquer) — they peel on dense tropical hardwoods.
