Dicor Roof Sealant. Do I need to use the Part 1 Cleaner?

Use the cleaner IMHO

Cleaner. Same when using Eternabond tape.

Use the cleaner. Do it once, do it right.

OK..good enough for me. I'll order the cleaner today. Thanks

Another question.... watching video on the Dicor cleaning/application system, it suggests wrapping the RV in plastic prior to applying the cleaner.
Is this really necessary?
This plastic wrapping is the reason I haven't done the Dicor system before.

Thanks

Can you be a little more specific in what you are actually sealing? Vents, seams, entire roof? I would have told you that denatured alcohol is what I clean my rubber roof with before sealing. As for outside edges near the siding, I use some green painters tape.

I want to clean and apply a roll on sealant/coating to the entire roof.

Hello. I need to seal my TT roof. I never used the Dicor cleaner in the past. Just Dawn detergent and water.

The "Dicor System" calls for the part 1 cleaner so the sealant will work correctly, etc..

Should I actually use this, or can I just give it a good cleaning with some detergent and water?
Thanks

I used this product last spring with great success. First, it is imperative to use the cleaner as it also acts as an activator for the sealer. Second, I wrapped the entire trailer with the very thin plastic sheeting as Dicor says the activator/cleaner can stain the sides of the unit. Don't forget to take off the AC shroud, reefer shroud and anything else you don't want the sealer on. After cleaning the roof I removed the plastic immediately. I went around all of the openings with a brush at least twice. Finally rolled the entire roof 3 times with the proper amount of time between coats. Also went around the edge of the roof where I couldn't roll with a brush 2 or 3 times. Took an entire day with almost no help after putting the plastic on. Roof looked great then and still does after ~16 months in the AZ sun. Don't try to cheat, do it once, do it right and move on to something else.

Thanks for all the replies. I'll get the materials and plan for a day.

no, Lap sealant is so sticky and gooey that as long as there is no obvious dirt, or a layer of skum it will stick. if you are happy with your soap and water cleaning job then you most likely have cleaned it good enough. I have never prepped a surface with special cleaners, maybe rubbing alcohol, but usually just car wash soap or just windex and it always seals.
