Here's the situation ... Posted by RS [Email] ![]() ![]() ![]() In Reply to: Re: OT: What's a good water-based wood sealant?, Dean, Fri, 9 Jan 2004 15:13:22 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I have the good fortune (?) to live in GA. We have a substantial vapor barrier on the ground in the crawl space. The soil is the lousy red clay that has some water-conducting fractures. Obviously, winter isn't the problem time of year.
Condensation is the problem during the summer, on both the A/C ducts and on the joists because of the temperature at which my wife wants to keep the house. I can deal everything but the uncontrolled temperature variable - that's something that is unchangable.
Crawl space is vented for combustion air. As an engineer, I know this makes things complicated.
Since termites and other insects which might nest in materials like fiberglass insulation are a problem here, I'm hesitant to install that, even though I know it's the best option for moisture control.
The reason that I'm asking now is that winter is the driest time of year and I want to keep the wood as dry as possible when sealing it. there's a window of about a month and a half in which it's not too humid to do the kind of work I want to.
Sealants which leave a waxy coating or soak the wood with a solvent aren't what I'm looking for from a fire-control standpoint.
I'm thinking that something on the order of spar varnish might be the least of the evils for this situation, considering all of the variables.
I may just give up and put a layer of conrete over the vapor barrier.
Georgia construction practices SUCK, big time. I will never, EVER buy a house with a crawl space again.
