Bamboo Flooring Tips
Many builders interested in building sustainable homes are choosing bamboo as a flooring option. Bamboo flooring has grown in popularity because it’s better for the environment. It’s extremely durable, and looks great in homes.
Bamboo is not a wood at all. It actually is labeled as a grass. It’s popular as a building material because it is very hard, strong, and dimensionally stable. It’s environmentally friendly because it matures in three to seven years, regenerates without the need for replanting, and requires minimal fertilization and pesticides. Larger species of bamboo have been used in construction for thousands of years. In today’s modern Asian cities it’s common to see a large buildings being constructed using bamboo scaffolding.
In the making of bamboo flooring, the hollow round shoots are sliced into strips, which are then boiled to remove the starch. The strips are dried and then laminated into solid boards. The bamboo is then treated with a preservative, either before and/or after it is laminated. Most manufacturers offer both a light, natural-color flooring and a darker, amber variety. This amber color is achieved by pressure steaming the bamboo, which darkens it by carbonization.
All the products are laminated using urea-formaldehyde (UF) adhesive. Be sure to check to see which manufacturers offer products with a low level of adhesive, as UF resin tends to off-gas formaldehyde after production The amount of resin in a laminated bamboo product is much less than in a particle-board-type product.
Nearly all bamboo flooring sold in North America is produced in the southern Chinese province of Hunan in an area known as “The Bamboo Sea” for its extensive bamboo forests.
You can use conventional installation techniques to install bamboo flooring, following the manufacturer’s instructions, and using the recommended adhesive or fasteners.
Here are some helpful installation tips:
Checking the sub-flooring to make sure it’s clean and free of defects and debris. Make sure concrete floors are fully dry and sufficiently cured before installation.
Leave the laminate flooring out 24 to 48 hours before installation so that it can acclimate.
Make sure a continuous vapor retarder is in place before installing the flooring. The installer should overlap the vapor retarder sheets, and seal the joints with adhesive tape.
Use 1/4″ shims or spacers between the planks and the wall to provide an expansion/contraction joint. Spacing the flooring away from the walls allows the finished flooring and the sub-flooring below it to expand and contract without warping or buckling. Spacers should go in about every 12″ and at every joint between planks. Base molding will hide the gap.
For the best appearance, lay the planks parallel to the longest wall.
Stagger the joints. Make sure the joints aren’t lined up row-to-row which will weaken the floor.
With each strip, tap a rubber mallet or hammer against the scrap piece to knock the new strip into position and eliminate the appearance of a seam where the pieces interlock. Continue the process throughout the room. Be sure to finish off the floor by removing the spacers when the floor is complete.
