Hi bw2
I’m sure not an expert, but Dicor does state that the adhesive must be water based or it will react to the EPDM membrane. They told me directly that being water based the flash off process [curing] works properly only because the chemicals are absorbed by the new substrate [new plywood]. The 901b/a adhesive will not join 2 pieces of EPDM together successfully. That being the case…what adhesive could a person use ?

Roof Membrane Replacement - AC

Hi Everyone
Today I completed installation of all the devices on the roof, including both AC’s & Sat Dish. I still have to reinstall the gutter extrusions which will then ty down the membrane along the sides & of course, then I have to apply “self-leveling caulking” along all seams & fasteners.
I decided to do some maintenance on both AC’s before I installed them. This included, chemically cleaning both evaporators & both condensers. On the 15K rear unit you can see evaporator plenum insulation which deteriorated & was picked up in the airstream & collected in a few areas of the condenser, along with cottonwood fluff, & lots of dirt ! Both units cleaned up well, I also replaced foam gasketing used to separate conditioned air from unconditioned air, I also reglued several foam gaskets which the glue had dried out & allowed the foam to fall to the bottom of the units, resulting in air bypass. I purchased the foam seal mounting kits from Camco & found that they have made improvements, in particular the foam blocks which maintain clearance between the compressor mounting bolts & the roof as I mentioned in my first couple of posts.
Tomorrow I will wire up the AC’s & a “fantastic fan” that I installed in the bathroom in place of the original skeleton motor unit.
