Help with shed door threshold...

[psychob0b1977]

Hi all,

I built a large shed last summer, and I used a 5 foot wide out swinging double metal door that I had aquired for free as the shed door.

The problem I am running into now, is that the doors have a gap at the bottom that allows snow, rain, wind, dust, and critters easy access. the simple solution seems to be that I need a threshold under the doors. The problem, its that the shed is built on an asphalt pad. I'm at a loss for how to attach a threshold to the asphalt surface. If it was literally any other surface, I could screw it down and caulk under it to stop water seepage. But screws don't work well in asphalt and I'm not comfortable using only caulking to secure it. Any advise would be awesome.

Thanks Bob

How about a rubber sweep on the door instead?

psycho, you have not been descriptive enough in your dialogue. More info is needed to how the weather is getting in, be in wind driven, slope issues, standing water, or other.

the specifics will have your question answered for the right application.

Epoxy gel is good for this.

The snow, dust, and leaves get in by being wind driven. the rain gets in because of a few reasons, mostly from splashing on the doors and just dripping down the door and soaking the floor near the door. Some of the rain gets in from wind driven rain.

The solution I came up with is to use a threshold to seal the bottom edge of the door. Because the door swings out, I can use the type of threshold that its mounted just inside of the door with a rubber gasket that seals to the bottom 1/2" of the door.

That type should stop all of my issues, but I'm not sure how to attach it to the floor. I thought about using some sort of adhesive, but I am not sure what type to use that would be strong enough in all temperatures, and be water tight.

Exterior grade Liquid Nails will do it if it has a flat bottom. If not, put down a wood strip and screw into that.

without knowing the specifics...........

rebar driven through a treated 2x4 through the asphalt should solve most of your problem. can add cut shingles as well (between board and asphalt) to adhere and give better protection from seepage and will add it backstop for door as well.

If you have a slope issue, trench drain.........

If you have standing water, port to the low side..........

gutters over shed door will help divert excess water away from shed.........

snow, move further south or shovel.........


some ideas??

It doesn't have any slope or standing water issues. the door is approximately 4-6" above the ground level.

I think I'm going to try the exterior liquid nails, and glue down a threshold and see what happens.

In a situation like this a picture is worth a thousand words. I don't think LN by itself is gonna hold it but that or some silicone to act as a sealant and either some redhead screws or a few shots from a 22 caliber nail gun and it'll be there for the duration.

In addition to the const. adhesive, use a lag bolt/shield like they do with speed bumps in parking lots.

or maybe these.

Pictures would really help. What I envision it a shed built on an asphalt driveway.

How do you have it framed? How much of a gap is there under the doors? You may not even have room for a threshold.

Can you post a pic? If so, then solutions will come forth.

Get an aluminum threshold, cut it to length, and glue it down with a liberal application of block wall and cap adhesive. It comes in tubes for the caulking gun, and is available at most DIY stores or places that sell landscaping block..

Hi,
I have two options here:
https://www.garagedoorstuff.com/product/garage-door-weather-seal-threshold-bottom-seal/

https://www.garagedoorstuff.com/pro...-aluminum-weather-seal-threshold-bottom-seal/

Both can be glued down, the suggestion of exterior Liquid Nails is a good one, also, Loctite PL375 will work, that is what we use.

Thanks
Frank

''It doesn't have any slope or standing water issues. the door is approximately 4-6" above the ground level.''

Is that a typo ? 4'' to 6'' above the ground ????
