We're going to remodel our basement; it was really hideous. There's
basic paneling, but the real killer was this old orange and brown
honeycomb carpeting that's been breeding mold for 30 years.
I'd been given a sales pitch by a company called Basement Solutions
of NE. They have a concrete sealant that is supposed to penetrate a
couple/several inches into the concrete and help cut down humidity and
radon. I was hoping to get that done before I install all the new stuff.
A couple of questions:
1) anyone every had any experience with these guys (or their product)?
Positive or negative testimonials? I know the type of sealants that I
can get at Home Depot are entirely topical and don't really work that
well applied to the interior.
2) What's the best way to get up the carpet glue from the cement? I was
thinking of using a wire brush after I scrape off all I can.
NEVER put a barrier between the inside wall. Also, NEVER screw, bolt or
otherwise attach anything directly to the concrete floor or walls. If you
plan on not putting up walls then sealent on the cement may be ok, but don't
seal the walls and then put an interior wall up after that. Also, sealent
on the walls will never be a perment solution - IMHO....
Do you actually have mosture coming through the walls/floor or simply high
humidity? If it is the later get yourself a dehumidifier and a hygrometer
and see if you can get it under control that way. Also keep any basement
windows/doors to the otside closed at all times. When you let in warmer,
mosture laden air it will condense on the cooler surfaces in the basement.

Sounds like the product they are hyping is "radon seal". Do a web
search for more info. There's a LOT of silly hype out there
(especially about radon), so be skeptical (especially be skeptical of
the manufacturer's web site). I have never been able to find any
reports about this product from independent laboratories.
Securely tape a 12"x12" square of aluminum foil to your concrete
basement wall. Leave it there for 48 hours, then remove it and inspect
the side that was facing the concrete. If it is dry, don't waste your
money on the sealant.
If you DO decide to go ahead and spend the money for this, it is
CRITICAL that the surface be prepared properly first, or you are
wasting your money. All efflorescence must first be removed thoroughly
with an acid wash. This can be a nasty job, so there's incentive for
contractors not to do a thorough job of it. If you do it yourself,
please invest in appropriate respiratory protection, especially if
there's no ventilation in your basement.
