Ridge vent effectivenes and sealant


Hi:

We're thinking of having Foster 40-20 sealant applied inside our attic. The area is ventilated by a ridge vent and soffit vents. Should the ridge vent/soffit vents be taped over to protect them from getting sprayed over with sealant? If they are sprayed, will it impact their effectiveness?

Thanks,
JDL

What is Foster 40-20 sealant?

Is this a closed cell SPF insulation to be sprayed on the interior surfaces of your attic?

Foster 40-20 is a antimicrobial fungicidal sealant, a "polyacrylate copolymer emulsion." I'm thinking of having it sprayed over the joists and the underside of the sheathing in the attic, and I'm wondering if I need to cover up the ridge vent and the soffit vents, to prevent them from losing effectiveness.

Thanks!

Well, then it also sounds like you must be doing this for Mold Remediation and Prevention.

I do not know how thick of a mill coverage this products applies in, but it does have specific installer safety concerns and specialty handling and application procedures.

Check out this link:

Since this must be an elastomeric coating like product, it would make sense that any surface area in direct contact with its application technique would become coated as well.

I would suggest that you take a width of plastic visqueen and tape it below the Ridge Vent Slot Cut-Out, so that when the application of the material is dry, you would be able to peel the tape and the visqeen away from the interior attic structure.

I also would suggest contacting the Foster Company for direct and more specific instructions on that technique though, since this seems to be a mold remediation effort and I would not want you to jeopordize your environmant by not having this application cover all affected areas.

I briefly read the linked document, which also stated that it could be brushed on, so for those areas the tape was previously covering, you should consider that for the final end result.
