Red Balau Deck Protection, Restoration and Maintenance

By Bill Christou, 06/11/17

Red Balau is a truly difficult wood species to pin down. It is sold under names such as Nova Batu, Lightning Brand Mahogany, ExoDek Mahogany, Mangaris and Red Balau. The actual species name is called Red Balau and belongs in the Shorea Spp. Family.

Red Balau exhibits a color, hardness, durability, and grain which is considered similar to Mahogany and is a common reason why so many home owners choose the specie for use in their outdoor living projects.

Just as other species used for decking require specific steps to keep them protected and looking stellar, so does Red Balau. If you have experienced unwanted changes in the appearance of your Red Balau deck or if you have invested the time and effort into installing a new deck, in today's blog post we will try to provide you with answers on how to properly care for and protect your investment.

Restoration Techniques for Existing Decks

As with countless other species used outdoors for decking, Red Balau requires some periodic maintenance to keep the boards well-protected and in their original state.

We understand that many homeowners have made large investments in creating their ideal outdoor living spaces. Unfortunately many homeowners have not been fully informed on what it takes to keep their investment impeccable and are truly disappointed and surprised when they witness changes occurring to their decks. Many times maintenance has been overlooked and the original look slips away over time as exposure to the elements begins to make its effects felt.

Fortunately for most homeowners an amazing attribute of this durable wood is that it can be brought back to a brand new state through time tested quality restoration techniques which can be easily carried out by the average homeowner.

Step 1 - Clean Debris off Deck Surface

The first step in Red Balau deck refinishing process consist of sweeping any loose leaves and dirt off the surface. This way we are not forcing debris into the surface pores during our next steps.

Step 2 - Power Wash

It should be noted that light pressure washing followed by re-application of oil finish will gradually darken the hardwood decking.
If you desire to bring the finish as close as possible back to original color, then a deeper pressure washing is required. For deep pressure washing, a maximum pressure of 2500 psi should be used at a distance of no less than 4” in order to avoid tearing the wood fibers.

Step 3 (optional) - Touch Sanding

Sanding with a conventional hardwood flooring sander will also bring the material back to its original unfinished color. Sand paper grits as low as 80 grit can be used on hardwood decking. It’s important to select a sander with flexible backer so that the sandpaper can follow the contour of individual boards. Higher grits such as 150-200 will wear out extremely quickly and get gummed up with oil and dirt. We recommend starting with 80 grit and only dropping lower if the deck hasn’t seen any maintenance for several years.
It is also possible to use a random orbital sander, running the handheld sander down the length of each board. This is certainly a tedious process so we strongly recommend you have knee pads and Advil at the ready. Last we checked, you could rent a floor sander from Home Depot for about the same price as a decent handheld random orbital.
Once you have sanded the deck, removing dust from the surface grain is key. Ideally another light pressure wash should do the trick and will also eliminate any remaining contaminants such as mold and algae. After this process your lumber will look as it did when you originally installed it. Your deck is now ready to be sealed with an appropriate oil base blend to protect and maintain the deck boards close to their original condition.

Step 4 - Reapplication of Weatherizing / Protective Coating

The final step of your Red Balau deck refinishing process is application of the weatherizing or protective coating. There are a slew of products on the market that claim to protect and keep the look of your deck.

There are many things to consider when choosing a product, the most important of which is to keep in mind what the wood will look like and how easily it can be maintained in the future. The best products are penetrating sealers. We stay away from water based and film forming finishes as they look unnatural and our experience has shown that they are not easily maintainable and can become slippery when wet.

We recommend homeowners coat their Red Balau decks with a penetrating oil finish. Our experience is that oil-based finishes reach deeper into the pores of the wood's cellular structure to add protection while enhancing the grain. When applying the actual oil finish, it’s critical not to let the oil puddle up. We find it most effective to roll it on, not too heavy, and then back roll it within 2-3 minutes. Too much oil on top of the boards will not offer additional protection since it will not soak into the wood; and, too much oil will show footprints for weeks after finishing.

The coating will naturally and gradually dissipate over time. Microclimate in your area will determine when periodic maintenance is again needed, however the advantage of oil based finishes are that they can be reapplied easily.
