RE: Lumber Liquidators Morning Star and Supreme Bamboo

Dear Mr. Middleton,

Thank you for your interest in Bostik Hardwood products. The following Lumber Liquidator products were evaluated with Bostik adhesives.

Morning Star Bamboo
Thickness: 5/8"

Supreme Bamboo
Thickness: 5/8"

The above bamboo products were evaluated with Vapor-LockTM, Best®, and EFA+. The adhesives were evaluated for trowel-ability, coverage and adhesion to the wood. The materials were ranked on these attributes. Since all were acceptable, they were ranked "Better" and "Best".

Vapor-LockTM can be used as an adhesive and a moisture barrier. To utilize Vapor-LockTM in this manor, it should be applied with the recommend trowel. This trowel will allow 100% transfer of material and a uniform layer of material. This is critical to obtain the moisture barrier properties.
