To sausage or trowel?

[edge10]

Hi,

Just after some advice - we are installing solid hardwood timber floors (130mm X 19mm) over concrete. I have had some tradies in to quote on installing the floors and all of them have said the method wil be to use builders plastic first, then ply, then glue. Some of them suggest trowelling the glue while others have said no you should sausage it on? Which is best and which product should they be using?

PS: House is 50 years old so moisture content shld be low.

Thanks,

G'day Edge10,

As a chippie, I can happily say that the information you are getting about the plastic/ply is spot on. Its the only way to lay floors onto a slab. I have seen some direct stuck and generally it spells disaster. I am assuming you are secret nailing?

With the installation notes given by the timber flooring suppliers, their warranty is generally only ever valid if the glue is troweled on rather than sausaged. We usually use a 4mm trowel and have never had a call back to a job. It is a little harder on the knees, and the apprentice usually ends up with glue from fingertips to elbows, but it does give a great result.

Hope this is what your after.
