Two weeks ago, We had Sealection 500 sprayed in wall cavities and under roof decking (metal roof) for our new home build. The smell seemed minor by 2 days after, then the ingition barrier – Blazelok IB4 was sprayed on entire roof deck. One week later, the smell is as bad a the day they sprayed the Blazelok IB4. Cure rate is 2-3 hrs so something seems wrong.
The chemical smell burns your eyes and nose, I can taste a metallic taste on my tongue and get dizzy after entering the home if any windows are closed.
In fact, the smell is strong enough and sweet enough that prior to entering the house, it hits you outside.
The only time the smell is tolerable is when every single window is open, but when shut up a bit, the smell returns at full tilt.
We have requested that our General contractor to withhold sheetrock since we worry the offgassing will be shunted and worse that the smell will be absorbed into the sheetrock.
I have called Demilec and asked for a tech rep to come out and test our product, but am only being routed to their Sales rep.
