I am trying to finish our floors while my husband is away for the next couple of months and need some advice. I have radiant hot water tubing under the 3/4 plywood flooring. I planned to use the pink paper - but after reading some of the sites, I wonder if that is correct, would it block the heat is there something better out there? BUT, I am more worried that when I nail the 3/4 hardwood floors, I will pierce the tubing. I plan to rent one of those nailers- so any and all suggestions would be appreciated. Thanks in advance.
