This is very common, we deal with it several times a week.
In short, AFM Safecoat (safecoat.com) offers several products that help to
seal in offgassing. Can¹t guarantee success, but we have an extremely high
success rate, even with chemically sensitive (MCS syndrome) clients. A
reasonable approach is to seal in surfaces as best as possible, then see if
you can isolate remaining offgassing culprits to seal again. Don¹t
necessarily need to sand the surfaces down to unfinished unless they are oil
based. Last step is to replacewhich is a follow-up conversation we have on
appropriate replacements depending on the space, use, functionality,
durability, and personal design preferences. In any case, there¹s almost
always a healthy and green solution. Summary rundown:
* for the carpets, can first try to seal with Safecoat¹s carpet trifecta:
shampoo, then Carpet Seal to seal the underside, then the Lockout to seal in
the carpet fibers (and provide stain protection).
* for cabinets and similar finished surfaces: coat with Safecoat Hard Seal,
which is a gloss sealer specifically to seal in offgassing, or coat with
Safecoat Acrylacq, which is a very nice furniture and trim finish that also
seals in offgassing. Probably 2 coats. Satin or gloss options. If existing
surface is glossy or a laminate, sand a little to break the skin first then
clean to give some grab to adhere to.
* for floors: coat with Safecoat Polyureseal, a very nice, durable
floor/wood finish that also seals in. if over an oil based finish probably
need to strip first (or at least scribe it) b/c oil and water don¹t mix.
* painted walls: repaint with Safecoat paints. Flat, pearl, eggshell, and
semigloss sheens. Can most likely match the same color that¹s already there,
and it¹s great paint plus it will also seal in the offgassing. May need to
first prime with a coat of Safecoat Transitional Primer.
