How to Maintain and Care Cumaru Wood?
Maintenance and care are essential to maintain the beauty and durability of wood over time. Here are some steps and tips for maintaining and caring for Cumaru wood:
Regular Cleaning
Dirt, dust and debris can build up on the wood and affect the natural color and grain. So clean or vacuum regularly.
To clean the surface, use a damp mop or cloth with a mild, pH-neutral wood floor cleaner. Avoid using excessive water, as excess moisture can damage wood floors.
Finishing and Sealing
Finishing and sealing are essential for outdoor furniture because wood can discolor when exposed to inclement weather or moisture. Sealing creates a protective layer on the wood surface so that outside elements do not damage the wood.
Avoid Harsh Cleaners
Avoid using harsh chemicals, abrasive cleaners, or wax-based products on kumquat wood floors, as they can damage the finish and the wood. To make homemade wood floor cleaner, combine 1/2 cup distilled white vinegar with a gallon of warm water or use Bona Hardwood Floor Cleaner Spray.
Maintain Relative Humidity
Maintain proper indoor humidity levels to prevent excessive wood expansion or contraction. Ideally, keep the humidity level between 30% and 50%. Using a hygrometer is the easiest way to measure the humidity in your home.
Prevent Sunlight Damage
Cumaru wood can discolor or lose its natural color over time when exposed to direct sunlight for a long time. Use blinds, curtains or UV-blocking window film to protect your wood floors from prolonged sunlight exposure.
Periodic Refinishing
Over time, Cumaru wood floors may show signs of wear, including scratches and dullness. In this case, to restore the floor’s appearance, refinish it again periodically (refinish every seven to ten years.).
Refinishing usually involves sanding the surface to remove the old finish and then applying a new finish or sealer. A professional should do this process.
