Dicor Sealant question for TPO roofing
After searching for 30 mins on various threads and not finding the answer, here is my question. I know from my search and checking that my Alpine has a TPO roof. I am desiring to install the Ultra Breeze vent cover over my Fantastic fan. It requires removal of 4 screws to mount. The entire frame is covered in sealant and cannot simply remove sealant just around screw holes as you need to remove applicable amount to allow bracket to seat down so the screw will set. My question is Dicor makes an Ultra Sealant for TPO roofing and has a 2nd part which is a primer to make conditions for adherence better. My thoughts are this is probably good for an entire roof vent replacement. But for such a small area about 1.5 x 1.5 inches, would it really be necessary to use primer or can I just use the sealant. I know the EPDM and TPO are somewhat similar and reg lap sealant does not require the primer.. Just seeing if anyone else has encountered this on their TPO roof. Buddy of mine used the regular Dicor sealant for EPDM on his and had no leaks. I believe in following directives and if the ultra sealant is for TPO than that is what I will use..just not sure on this primer issue.. Thanks!!!!
