Bamboo Wood Bath Sinks Care Installation and Maintance
Wood and bamboo sinks have gotten quite popular in the last few years. The sinks are wood and do have a clear coat on them which does need to be reapplied. How often depends on your project, your use, how often the wood / sink stays wet, how often water is added to the bowl, etc.
The drain installation is extremely important that it is installed perfectly flush and level and that no water remains in the sink after use. Water on wood contact is not wanted. We recommend after you buy a new sink and before installing, you add a thin layer of cleaar silicone in the drain area and allow it to dry overnight before installing. This will add one more layer of protection.
You will from time to time need to reapply clear coat protection. This may require the sink to be uninstalled so that every surface can be covered. You can generally use a polyeurothane satin finish to reseal your sink. When applying the product the sink should first be completely clean and lint free. Any blemishes or marks removed. If you have any wood decay from waiting to long to do this process, sand the sink down in that area and sand lighting the entire sink surface with a very fine grit sandpaper. Make sure any black wood rot is removed and the area is smooth. Remove all wood shavings or dust from this process.
The clear coat can be applied a few ways but a lambs wool applicator like you would use on a hardwood floor will work the best for smooth finish. THIN coats best. Better to add a few very thin coats than one thick one. You will be happier with the finish. If you do it and you don't like the finish sand it and do it again.
The reason I suggested satin finish is the sink will not be so shiney after it is done and satin is more forgiving with any blemishes in the finish.
Take extra care to give extra sealer to the drain area, including the bottom of the sink. Protect the wood, cover it in sealer.
