Lol Alex is Dap

You Might be taking about quad max? Quad is sticky but nowhere near as messy as quad max

Quad max has a lot of plasticizers in it. They will migrate out and the sealant becomes brittle. Also if you took it too thin the sun will destroy it

Maybe as the one visible drain shows signs of moisture but not this amount of water. I also discovered this window well this morning that is directly across from the leaky floor picture

Update: guessing this window well I opened up is the problem picture

All depends where you are using it. Silicone in kitchen and bathroom. For exterior applications a polyurethane caulk will allow expansion and contraction and resit UV breakdown.

Pulling up floor to look for the sump pump? If so, no need and just look for the discharge pipe. I’d be very surprised if they put flooring over a sump pump pit.

+1 for Quad. Frustrating to install due to stickiness (wear disposable gloves) but seals so gooooood.

I think this likely true. There is one drain that is visible elsewhere in the basement, and I found a very small amount of dampness near it. I will just have to look harder for the sump pump. My guess is that this drain is likely closer to the sump pump and thus overflowing more. Does that make sense? Trying to decide where to start pulling up floor to keep it to the smallest amount possible.

If you do this, make sure you insulate both the delivery and return pipes to reduce the amount of heat loss on water returning to the water heater to be reheated. Also install a pump with a adjustable timer so that water is not being recirculated at unnecessary times

Silicone is often a problem because it sticks to silicone better than anything else. Over time movement will cause silicone to peel off of one side of any joint and stubbornly stick to the other side and be a p i t a to remove. Quad is much better. Quad is a version of polyurethane sealant or PL. These sealants are difficult to apply and messy and they never really cure so they sort of stay gummy but they have really good performance as sealers

Siliconized latex or. Siliconized acrylic is a very different thing. Paintable. Water clean up. Stays flexible better than regular latex

Good old regular latex caulk my brand is white lightning is still a very good option for anything that's going to be painted over. It holds paint well and it's very inexpensive and easy to apply

There's also butyl rubber mostly used on metal like gutters and copolymer sealant like lexel. Very messy very difficult to apply but can provide really good performance for the right application

Hold up, Quad Max cracked?

OSI Quad Max is my Frank's Red Hot. I put that shit on everything.

Use Alex not DAP

I used a few different types bought in different batches applied at different times - caulked the whole house! All were well reviewed on Amazon. Strange

Maybe the product was bad. I live in US northeast, so we get a lot of expansion and contraction also. The point of the caulking is it’s supposed to be flexible. I think that you had a bad batch of caulking or something.

My mistake was assuming a normap handheld (but still hammer) drill would be sufficient for the job I suppose, thanks

We live in the uk so wet winters fairly hot summers so I get that stuff moves but was surprised how much it has cracked

Bit easier to search then. Unless the ceilings are finished.

There is a product called Quad. You can get it at big box stores. It isn’t very paintable. But you can groom it better than silicone. I would also recommend phenosil. My experience has been the clear caulking and silicone tend to yellow over time. But cracking after 2 yrs? That’s weird.

Silicone where you don't care about matching the color perfectly, want a great seal. Caulk and paint everywhere else.

Most silicone isn't paintable, so you wouldn't want to use it in areas that would get painted at any point. If you're looking at exterior products, polyurethane caulk is a good option as well.

Most caulks will do that if not painted. The siliconized stuff less so.

Buy why would you go through that trouble unless you don’t know concrete and only know framing? I see no benefit. It’s not cheaper, nor quicker, nor easier. I suppose if you have physical issues lifting heavy durock and mortar bags, you might prefer working with lighter wood, or possibly you know a way to cheap out on it, but to me it’s not sensible. What I believe is the case, is that a framer wants the opportunity to flaunt their skills, having only a hammer and seeing all problems as nails.
