Glue-down Installation: Trowel Size

I’m getting ready to install my Engineered wood in the basement. It’ll be glued down over concrete. What size trowel should I use for the glue? Mike, Plattsburg NY

You should always follow the glue manufacturer's recommendation. The recommended glues for Mirage flooring require a #9 v-notch 3/16" x 5/32" trowel.
