Greetings all. In late summer we replaced some old dark paneling in a room in basement.
I'll admit, I went with a low cost/cheap lite color panel. The old stuff, 50 years! was not in awful shape a very little bit of de laminating neededcleaning.
So we got busy with other stuff and about a month ago discovered a good deal of fuzzy stuff as far as 18" above the floor. Too, the new stuff barely held
the very thin fasteners which were pulling thru the paneling.
So....a dehumidifier is in the cards and after pulling the paneling I am thinking a painting of a sealer and maybe even a vapor barrier first. Oh...cement block walls, concrete floor and little air circ. it only has one foot square vent in the block.
FWIW our painter is suggesting another coating on the wall before anything else
Suggestions? --174.225.xxx.xx |

That paneling is a buffet for mold. Get rid of it. Drylok the block wall and install dens armor or densglass if you can find it. --70.44.xxx.xx |

Solid insulation board on the walls will not absorb moisture where the wall is no longer a cooler surface that will have moisture. Fiberglass insulation on walls will have mold where solid insulation board at least 2" thick along sealing all the joints with insulation tape will keep the wall closer to room temperature. Installing a sump then sump pump will drain off water from the foundation. Insulation over time will keep out mildew along with reduce the amount of heat required as a bare concrete wall will act like heat sink. --147.194.xxx.xx |

Concrete block is pretty porous and lets all sorts of moisture in. Drylock is a good paint to seal it better. You can also get it tinted if you wanted to just leave painted walls. But certainly do not use any materials that can absorb moisture, it is just a recipe for mold in a basement. --108.4.xxx.xxx |

When doing that Drylock, make sure you have that place very well ventilated. Even with proper ventilation, you are going to get stoned. --24.101.xxx.xx |

You need to start at the ROOT CAUSE of the issue. Where is the water coming from? Check the grading of the yard, should slope 1/4" per foot away from the house for the first 10'...or 2.5" total 10' away. CHeck gutters/downspouts...are they clogged? Leaking? Do you have proper extensions that take the water at least 5' from the house? No matter what you do in the basement, if there is ground water issues outside it will not fix the problem.
Also, buy a humidistat and take daily readings of humidity in the basement BEFORE you start running the dehumidifier, then do it again with the dehumidifier running, chart the results.
The REAL fix may be a membrane on the outside of the wall, underground...but that would be very expensive. --99.92.xxx.xxx |

I was really surprised at how bad the crappy panels acted…..but after all they are carboard with a printed design, or something quite like it.
Thanks to All. NE will look for densarmor/densglass.....is it hard to install?
Robert: thanks for the detailed reply. that route might the fastest and best for me. Also will add an R factor that be very useful overall.
Linda J: I sometimes follow recipes to get the best of me.
RayinPA: Yeah...I dod another side of the basement with Drylock....in Summer thaks ful for the breeze!
Hoosier: you did hit the nail squarely. We had a week or two of heavy downpour not long after the paneling went in. Too, Outside work was in progress and the downspouts failed. [so did I!]
Too, the grading needs attention, not alot as I have had the grading under control for many years, but got bit in the Adz this time 'round.
Again many thanks. --74.105.xxx.xxx |

Frank [NJ], Denshield, Densglass Gold & Densglass Purple are all a special type of drywall that is used primarily in commercial construction. It holds up well to moisture & is installed similar to regular drywall panels. If you Google them you'll find lots of info. In my area it's mainly sold thru commercial drywall suppliers like Kamco or Robert Knapp. --71.174.xxx.xx |

I like the Behr masonry paint better than Drylock. Much easier to apply, and the moisture level in our basement dropped significantly after we painted the walls.
Thinking outside the box...we just installed FRPs on the lower half of a basement's walls. Waterproof forever, super easy to clean, and never need to be painted. --104.230.xxx.xx |

Only 2 acceptable ways to do a basement wall
They are readily found on line
Either use rigid foam or stand new wall off the cement wall to allow it to breath
