RE: Bellawood Premium Underlayment /Michael Kort, Lumber Liquidators.

Dear Mr. Williams:

Per your request, Bostiks Technical Service Department has preformed a bond test with Bostik DuraGripT Hardwood Flooring Adhesive with the Bellawood Premium Underlayment submitted for evaluation, the following are our findings.

The adhesive was applied to cement board with a 3/16" x 5/32" v-notched trowel, the Bellawood Premium Underlayment was then laid into the wet adhesive and rolled to insure maximum contact, adhesive transfer to the bottom of the underlayment. After 7 and 14 days of curing, attempting to pry the underlayment off of the cement board, the underlayment separated with the bottom half well adhered to the adhesive and cement board.

Based on our findings, Bostik, Inc. is pleased to recommend all of our moisture cured wood flooring adhesives with the Bellawood Premium Underlayment. A 3/16 x 5/32 v-notched trowel is recommended to insure adequate coverage to the underlayment and approved substrates.

Please follow Bostik, Inc. most recent published data for proper installation methods.

If you have any further questions, please feel free to contact me directly at 951-296-6148, or you may email me at .
