I have the correct Dicor products, both cleaner and UV protectant, which will be applied soon. I was just giving the roof a pre-clean cleandown first and became a little alarmed at how slippery the EPDM gets when wet. After I nearly went off the edge the second time, I decided that there must be a safe way to do this.T1 Terry wrote: ↑Mon Oct 08, 2018 2:17 pmDid you apply the new seal coat after cleaning it David? The amount of white powder that comes off from the rubber membrane oxidising ya gotta wonder just how long it would last constantly exposed to the harsh Aust sun. Probably not an issue in the USA or Europe, but we got tough sunlight over 'ersupersparky wrote: ↑Thu Oct 04, 2018 5:17 pm I have spent most of the afternoon cleaning the roof on the Winny. EPDM rubber I think the covering is called. That was the most fun I have had for ages. That stuff is really slippery when it gets wet. A couple of times I thought I was going over the edge.
Does anyone have a tip for how to safely tie-off while working on the roof. It would be easy if there was something higher than the Winny to secure to, but I don't think the shrubs in the garden will support much weight.
I've cleaned the spots where I had to reseal stuff on Vik's roof, but I'll leave the rest for Vik to do, just in case I wash right through the air bubbles and create a water leak
They actually have a patch repair kit on evil bay that works quite well. I poured a heap of the Dicor self levelling stuff under the patch we had to do on Cathy Ashton's roof. The original solar installer had used some sort of glue that reacted badly with the rubber roof when they screwed down the junction box. I added the Dicor in an attempt to seal the holes they had made with the self tapping screws and to get the rubber around the patch area to attach back to the roof. Took a few days to harden up under the patch, but the end result was very good.

I want to get this done before summer as by the looks of it, the roof has never been properly cleaned or re-treated before.
I have a safety harness and all the right gear except for a suitable tie-off point. I know that some of the bigger dealers and repairers have a platform type gantry that they bring alongside the bigger rigs, but I have no access to anything that high.
I'm thinking about sucking up to the boss and seeing IF i could bring it in to work one weekend and work on it under the big carport. At least then I would be able to secure myself to something higher than the level I would be working on.
Another dumb Winnebago question. How do you work out where there is anything substantial under the EPDM, it all feels the same. I know there is a wooden frame under the sheeting , but don't know how to guess where to mount more solar framework. The stud finder gives the same result everywhere I check.
