Purple Heart wood is one of the most striking and distinctive exotic hardwoods used for decking. Known for its deep purple and burgundy tones, it delivers unmatched visual impact—but it also requires the right care to maintain its color and durability.
When Woodrich Brand was invited to clean and protect several Purple Heart wood decks in South Carolina, we had the opportunity to demonstrate what truly makes the best finish for Purple Heart wood. The difference between properly protected boards and those exposed to the elements was immediate and dramatic.
Newly installed boards displayed vibrant violet hues, while decks exposed to prolonged sunlight had already faded into a gray-brown tone due to oxidation—a natural process when Purple Heart wood is left unprotected.
Cleaning Purple Heart Wood Decking
Proper preparation is essential when working with dense exotic hardwoods. To achieve the best finish for Purple Heart wood, the surface must be clean, open, and ready to accept stain evenly.
For this project, we used Woodrich Brand EFC-38 Wood Cleaner, specifically designed to remove oxidation and surface contaminants without damaging hardwood fibers.
Cleaning Process
- Applied the cleaner evenly using a pump-up sprayer
- Rinsed thoroughly with a high-volume, low-pressure pressure washer
- Lightly buffed the surface to remove minor furring and smooth the grain
The result was a clean, refreshed Purple Heart surface with open grain, ready for staining.
Staining Purple Heart Wood Decks
Choosing the right stain is critical. Because Purple Heart is a dense exotic hardwood, surface-level stains often fail to penetrate properly and can mask the wood’s natural beauty.
For this project, we selected Woodrich Brand Hardwood Wiping Stain in Warm Honey Gold, a penetrating oil-based stain designed specifically for hardwoods.
This finish enhances Purple Heart’s natural tones while providing long-term protection against moisture and UV exposure—key factors in preventing premature graying.
Application Method
- Applied the stain with a pump-up sprayer
- Padded and hand-wiped the excess to ensure even absorption
- Allowed the stain to penetrate fully into the dense wood fibers
The final result was rich, conditioned Purple Heart wood that retained its vibrant character far longer than untreated boards.
A side-by-side comparison between unstained Purple Heart wood and wood treated with Hardwood Wiping Stain clearly shows the difference in warmth, depth, and long-term preservation.

A hardwood-specific wiping stain with deep penetration and UV protection works best. These stains absorb into dense wood fibers and provide longer-lasting color and protection.
How often should Purple Heart wood be maintained?
Maintenance intervals depend on exposure, but penetrating hardwood stains typically require reapplication less frequently than surface coatings and do not require stripping.
