My daughter says she found a deal for tongue and groove teak hardwood flooring. I notice that the entire lot is 12 inch pieces. Flooring (Bruce) I have installed before has contained pieces of varying lengths. It would be glued. Is it a problem installing teak flooring with all 12" pieces?

Small pieces with 12 inch length may be glued down. An ashlar pattern with the next row started with a half piece with any leftovers to be used for the starter board in the next row, or just random. Teak sands and finishes nicely. I recommend a light brown stain so the floor keeps it's color longer.

I don't thank you enough Pete

Thank you. I really appreciate it. Can you advise me on what glue you would recommend for teak flooring?

There are specific qualities for many of the glues for hardwood flooring. Sound transfer, sub-floor moisture resistance, fast stick, high build peaks from the trowel are some . I like a single component moisture curing glue like Bostick Best. It works great over all substrates and wood flooring materials. If you are gluing to concrete there are glues that can handle moisture from slab to a certain extent. an important prerequisite is having your sub-floor flat so the wood has good contact. Shorter lengths like 12 inches can conform better to an irregular surface, but more rough sanding will be necessary. The recommendation is to get the sub-floor to within an eighth inch with an 6 foot straight-edge and within a quarter inch with a ten foot straight-edge. Sand or grind the high spots first if necessary.

Thank you. And one last question: I've always used a nailer to put down hardwood flooring in my home. In this case, with it being glued, with standard underlayment in a ranch home with a full finished basement (I am installing the teak on the main floor), is it necessary to lay a barrier down first, like the 15# felt paper? It would seem that glued flooring would need to be adhered to the underlayment/floor and not tar paper. Thanks in advance.

There are glues that include a moisture barrier. Call the hearest wood floor distributor or ask a hardwood floor contractor. I prefer to glue directly to the sub-floor.

You could do a Herringbone pattern maybe ?

Herringbone looks doable for a non-professional. I'm resisting my daughter's ideas for "designs"; I know my limits! Thanks for the advice.
