Metal Building Sweating

Sealing new metal shed to slab

I have a new metal garage that meets the slab but is not sealed to it causing water to leak into the garage when it rains heavy. It isn't a lot of water but I would prefer no water at all. What can I use to seal the slab to the building?

Post a picture.
I'll make a few guesses.
The shed is smaller then the slab so the slab is sticking out past the shed forming a flat area for water to lay and get in.

Slab is even or at least close to grade.

There is no area dig out around the slab with stone in it for drainage.

Little late now to go back and "fix" it, about the best you could have done to slow down the leaking was put silicone under the bottom plates before the shed was built. Not a great way but it would have helped some.

I had a metal building installed last year and it has no insulation. The only time I am really getting any sweating is during the winter months. It is a pretty good amount during that time. How should I get rid of the moisture? Insulate or ventilate? If I insulate, what type of insulation should I use. I do work out in the garage during the winter and was planning on adding a stove or propane heater. Thanks for your help?

Got a picture?
Venting would make a big difference and would need to be done if you insulated anyway.
Propane heat puts out a lot of moisture, make sure if you do go with propane it's a direct vent.
Is this on a slab? No form insulation or vapor barrier added under the pore?

If you don't have any insulation and/or vapor control, the building will sweat if you heat it.

How much use are you going to get out of it and how much of an issue is the sweating.

Depending on the size and scope of the building, that is going to be an expense of some undertaking.

tucker -

Without a location on your profile, it is difficult to give a specific answer.

I think you are seeing condensation that happens when warm moist air rises and hits a cool surface (your uninsulated tin roof with zero insulating properties) and runs down or drips on everything. Get rid of the moisture (just about impossible for that type of building and use) by sealing every possible joint and totally venting every heat source to the outside. If you have a climate with humidity, just opening a door for a few minutes will destroy a previous efforts without some effective insulation on the bottom of the roof panels.

Moisture in metal building

I have a 25'W X 50'L metal building on a concrete pad that has a moisture problem. It is just steel tubing with metal sheets screwed on to it. I am wanting to fix my moisture problem. What would be the best way to do it? Insulate it? Install some fans to ventilate it?
