Would appreciate any suggestions as to the "best" adhesive to use to
fasten a piece of wood to the concrete foundation. Indoors usage.
Just the regular Devcon epoxy as sold in the hardware store, or are there
much better ones available these days ?
Gorilla glue ?
Or some, what I think are termed, Structual Adhesives ?
If so, Brand and Type, please, as I'm really not familiar with these types
at all ?
I would strongly suggest some kind of mechanical fastener. Any wood
attached to the foundation should be pressure treated, and the
chemicals used to treat the lumber will resist the action of the

Agree with the pressure treated problem/warning. The green treated
wood does not fare well with epoxy in my experience. However, I do
have set of cellar steps in a so-so environment that were assembled
from 'the other stuff', whatever that is, which are still sound a
decade later. So I guess the best plan would to be use a dry type
treated lumber and epoxy for maximum adhesion. Tapcons or RedHeads
sure wouldn't hurt.
Guess it depends on what the wood is being glued to the cement for and
what is the impact if it should fail at some point in time. PL
construction adhesive has a lot of holding power to where you often have
to destroy things to break the bond once it cures.
Another really good brand of adhesives is Sika.
and click on FIND A SIKA PRODUCT then Products by Application. One of the
categories is Multi-Purpose Structural Adhesives which you specifically
meantioned. I've seen some Sika products at HD.
In 1963 I put two coats of Lepages Contact Cement on both the sole plate of
the wall and along the line where I wanted to attach the wall. After all
this time and countless encounters with water, the sole plate is still
anchored firmly to the concrete floor.
I have not tried these types of glue, due to the cost and short shelf
life. However it claims to be waterproof and foams up to fill cracks,
if that is important. But, I have found the tradiitonal waterproof
wood glues (Titebond or Elmers) to hold up well over 15 years. The
problem with PT wood is that it is usually very wet when purchased,
and if dried it may twist, wane, cup, split and bow if not properly
weighed down or clamped. Most glues need a little preparation work,
ie, a clean dry surface.
Per instructions with the gorilla glue, you moisten the area to be
glued prior to applying the adhesive (apparently what causes the
foaming) so a dry surface is not what you want. And while the glue
itself may possibly be waterproof, the adhesion to the wood is very
poor IMO. I believe Titebond & Elmers to be far superior to Gorilla
and a lot less expensive.
