Whenever you are trying to finish bamboo plywood you will find that there are several things that you should keep in mind. Bamboo can be difficult to finish because of the nature of the wood. However, once you know the proper ways to finish it, you will find that the bamboo will be beautiful and last for a long time to come.
Step 1 – Mineral Oil
If you are planning on using this bamboo to prepare food on, then you will find that a mineral oil will help to protect it. It is a good idea to use the mineral oil regardless because it will help to protect your bamboo from warping, cracking and drying. It is important that you use a mineral oil and not a vegetable oil sealant. Any sealant that is vegetable oil based will eventually turn rancid and will contaminate anything that comes into contact with it, especially food.
Step 2 – Apply Sealant
You will need to get enough mineral oil poured onto the surface so that it will completely coat it when you begin to spread it around. Get out your sandpaper and make sure to go against the grain as you rub it in. If you use a lot of cleaners on your bamboo, then you will need to apply the mineral oil weekly to make sure that the bamboo is completely protected. Every time that the area is cleaned, a small amount of the mineral oil will evaporate.
Step 3 – Beeswax
Beeswax is also a nice sealant that will protect your bamboo. It is also food-safe in case your bamboo is used as a countertop in your kitchen. You will be able to find beeswax in multiple different formulas. The two most popular types are oil blended and as a paste. Make sure that you thoroughly read the instructions on how you apply it before you pour any on your bamboo surface. If you are applying the paste application, make sure that you follow the grain of the wood whenever apply it. You will need to apply this once a month.
Step 4 – Finishes
If you are not planning on preparing any food on the bamboo surface, then you will be able to use a wood varnish or a commercial finish. You will be able to find the finishes in both oil and water based solutions. Just about any type of liquid that comes into contact with your bamboo will be repelled with these finishes. It will also seal in the necessary moisture that is in the wood.
Step 5 – Apply Finish
In order to apply the finish you will need to brush a coat on while following the grain of the wood. Once the first coat has dried you will be able to buff it down so that the next coat will be able to stick. You will need to do this a few more times; make sure that you allow the coat to dry and buff it out in between coats.
