[RE-wrenches] clear sealant recommendations

[Will White]

We’ve use Geocel 2300 for years now with good results.  They’ve also come out with a new product specifically for solar:  http://www.geocelusa.com/product/all-constructionbuilding-products/s2-solar-panel-sealant-detail.html

I’m not sure what the technical differences are but I know it comes in a plastic tube instead of the paper one so that helps prevent them from blowing out when they get a little damp.

Thanks,
Will

Subject: [RE-wrenches] clear sealant recommendations

Hi Wrenches,

For the most part we are using Chemlink M1 sealant for to seal our rooftop penetrations. It hasn’t let us down yet.

M1 is a available in several opaque colors and grey is the most common. Sometimes we want a good quality clear sealant to put around conduit fittings, where our conduit enters buildings, etc. We used Geocell 2300 in the past and I don’t have anything bad to say to it but our current supplier doesn’t carry Geocell products. More recently we’ve tried Chemlink Clear sealant but I’ve already seen signs that it doesn’t hold up well in the elements – it seems to peel off the surface it was installed on and turn brown relatively fast.

Does anyone have a good multipurpose clear sealant that they like?

Best,

August
