I am installing a new entry door for my shop and the floor is a concrete
slab. What sort of caulk or sealing method would be best to seal between the
door sill and the concrete floor?
One fellow I met mentioned some sort of asphalt based sealant. Another
person mentioned putting a 1/2 inch of pressure treated lumber between the
door sill and the concrete floor.
I am not concerned about clearances for carpeting as this is for a workshop.
I just don't want air or water seeping in under the sill.
What is the best way to deal with something like this?
If you check the installation instructions for your new door it should
recemmend silicone and the best method to apply it. Just remember to lift
the door over the caulk and drop it in place rather than slide it in across
the caulk or you'll have a big mess. --dave
my standard procedure is to place a large bead of caulk under the
threshold when i put the door in (after i've made sure it fits, etc.
since it is protected from UV, what caulk you use isn't that important,
though the best is probably something like NP1 or Sikaflex or something

If you want it to last, I'd avoid silicone, asphalt or any of the other
My choice would be a marine adhesive such as SikaFlex 291 or even a
polysulfide caulk like BoatLife.
Find a local marine chandlery such as West Marine.
Even Home Depot will have 3M 5200.
