And if you watch a couple of videos on caulking it will give you some tips on how to get it straight and even. The back of an old toothbrush handle works very well if you want to tool it after your line.

Yeah in this case the rigid metal pipe from the dryer goes directly into the wall and meets the exterior vent

Okay I see. It's on been on the shelf around a week and it's only slightly bowed atm.

Will flipping the shelf not weaken it?

At the home center, you’ll find dryer vents generally come with a (approximately ) foot long metal 4 inch round duct that attaches to the vent. You pass that through the wall, screw the vent to the exterior of the house, and foil tape the part poking into your laundry room to your dryer duct (which can be flexible ducting as long as it’s not inside a wall.

Yes.

The more moist your environment is; the thicker shelves needed.

Some woodtypes can be better at it, the not bending, like oak.

But it really depends on where you live. Your climate. Humidity.

Ventilation is your best friend In this case.

I have a bookshelf that does the same thing. What I can do is take all the books off and flip the shelves over. I do it every year or two.

But yes, it will.continue to get worse. That's the problem with the cheap materials they use.

I guess the wrong tile in the wrong location. Perhaps this is what unglazed terracotta tile is meant for. I’ve seen people install that stuff inside and I never understood why. So the tile is cool because of it’s contact with the slab, I suppose if you had installed under floor heating you could turn it on to help prevent condensation.

Why's that?

Here's my wip on a very similar set up, with both shoe and caulk. I would skip the caulk and just use shoe next time

Oh well there's your problem. If it is screens then no. You would need windows to stop that much humidity coming in. A humidifier can't keep up with all of outside being humid and open windows.

Yeah, my thought was that they aren't getting a close fit between the wood and the tile because of the texture.

Denatured alcohol

recently tried with replacement looked close but wasn't the same. Now it leans one way a bit. Probably will replace soon.

I'd use 80 and go raw dog on it.

Most vents that I have seen come with an optional tube. This tube is designed to fit around the outside of an existing metal tube.

You might have to cut the vent tube shorter, depending on how close the end of the rigid pipe is to the outside wall.

This Alex really let me down on my last project, it has been cracking like hell. Had great luck in the past but wouldn't risk it again

Will a dehumidifier work with all screens? Would it help if we put up curtains as well?

I can see that working very well!

I’d rent a flooring sander and go to town. Can’t be more than $100 for a day rental

If you build a simple stand to support the weight of the knives, you can then use silicon to attach it to the tile, avoid the grout joints, to keep it from leaning forward.

Dehumidifier for that room? It isn't the tiles fault that you live somewhere with high ambient humidity.

This is the correct way to do it.

You are 100% correct. 1/4 round molding is the way to go. Less maintenance and looks good.

I had the same issue, bought the Fluidmaster 555CRP8 Universal PerforMAX 5 Minute Toilet Flush Valve Repair Kit 2 In. From Amazon and it fixed it
