Should there be a waiting period before applying aluminum coating to modified bitumen and if so how long?
yes 90 days so it cures 1st
I say 90 days of 50+ weather to let the surface oils migrate out and prevent disbondment, but some manufacturers say you can coat it immediately.
If you’re using granulated, then it is always too soon to aluminum coat it.
my old boss would always insist on 60 days,but i checked w/my supplier and they say it should be 90 days
be safe do what the mfg says.
but ive coated em the same day, two days later,
two weeks later , two months later, two years.
call em like i seees em
