Herculine in cold weather

Is it ok to apply herculiner in cold weather? Im going to do my tub this december in NC. I had a buddy tell me he did it in cold weather and his bubbled up and peeled everywhere and he said he sanded. Does anyone know what was the cause he did wrong ect?

I would refer to the product data sheet but it sounds like he applied it below the minimum temp or the humidity wasnt right and it never cured. (Drying and curing are different things)

I couldn't find a product data sheet online but herculiner website says it can be applied down to 32°F but it didn't denote if that was ambient temp or substrate temp. Also no mention to humidity other than low humidity requires extended cure time.

Cold weather causes all coatings to cure slower. The fact that your friends job bubbled and peeled was prob not a result of cold temps but of inadequate surface prep (not scuffing enough and maybe not cleaning well after scuffing)

I would not push anything to be applied as low as mid to upper 30's. You really need to be upper 40's at least to avoid curing issues. Low humidity and low temps when applying moisture cure type coatings like Herc could cause it to not cure fully and stay that way.

Do yourself a favor and try to get a heated space to work or wait till spring. Avoid using any heaters with a flame if you going to work with Herc which has flammable solvents

Any 2k component system needs atleast 55 degrees to work properly. Under 55 the components dont cross-link, while it may seem dried it is not under the surface.

I'd wait till the spring time. Then you have no worries and can work on it in the nice weather while watching the ladies walk by.

When I did my TJ it was about 45-47 degrees. In the 7 years I had it, it never peeled once or anything. But I was very strict on the preparation.
