Hello, I was wondering what's the best product to protect your wall from humidity.

I don't know actual products, but a de-humidifier will take away humidity. We have one running in our basement all summer.

Please answer below - are you talking about moisture from the earth surrounding your foundation getting in, or do you mean moisture getting in and out of above ground walls?
The steps are very different for each.
tickle, studies have shown that a dehumidifier in a basement is actually drawing moisture through the walls. Concrete is quite porous. (Of course the best solution can get pretty expensive.)

We don't have exposed concrete walls; have a moisture barrier, small basement, dehumidifier works perfectly for my purpose.

OK tick sorry, mine is exposed (and damp).

I do agree though that with an older home such as yours and exposed, it wouldn't make any different what you had down there. It would sill be damp, right. My house was built in the 40s but basement was renovated after a burst water heater and they did a good job of taking off all old panelling and replaced everything.

What are you looking for exactly? What sort of area do you live in, what wall (exterior, interior) are you talking about? Are you asking about insulation, drywall, paint, etc. etc. Do you have an existing problem with humidity, mold etc, or are you renovating and looking for the best products on the market in order to prevent issues in the future?

We need more info.

My house is built into a slope with the lower level 3 sides of concrete on a slab (no basement per se). It's only 45 years old, but the driveway was built on the slope aimed 200' right at the house, so rain runs right at the house. Then to make it worse, there's a big area of ferns and groundcover that sits low, so water collects there too, before soaking under the driveway 10' and into the foundation.

Anyway, sorry to preempt OP's question.

Please, let's try to keep this pertinent to the OP's question. We really don't have enough info to give advice, and discussing our own situations, our own homes, that's not going to help.

Let's allow the OP to come back, give us more info, and then we can respond appropriately based on facts, not assumptions, and not our own situations.

To the OP, please see my previous post, provide the info I've asked for, then we can go from there. Until then, no one can give valid info as we really have no idea what you're dealing with, or what you're looking for exactly.

Thank you.

Live in Florida where we have cement outside walls and very high humidity. My AC draws the moisture out of the house just fine. Please answer the above questions with more information. Do you have special needs? Regards, Tom
