Masterseal NP1 sealant FAIL
Just wanted to post this so that anyone considering this in the future will know.
I was sealing all rivets and seams from the inside.
I was out of Trempro 635 and did not want to wait for the mail.
So I check out Lowes...….
BASF Masterseal NP1
also known as Sonolastic NP-1
used for acoustic damping
Interior and exterior
meets VOC requirements in all 50 states
used 12 tubes.
The problem. While it works , the smell is way to strong and filled the barn. 5 days later, it was still to strong in the airstream.
I did not notice this while I was putting it on.
Decided not to wait any longer. It had "hardened" enough to peal 95% of if off the walls. Leaving behind residue.
Smelled much better the next day. and the next. Just a hint left.
Ordered and resealed with Trempro 635. NO smell at all, at least to me.
So much for not wanting to wait for the mail. I will not make that mistake again.
