Silicone based sealants


#1

I have a flat roof. I use Henry wet patch to do the patch work, but want to roll on something to really give it a nice protective coat. Is it ok to use the silicone based sealants and still later patch with the Henry wet patch. I am going to home depot where I have a credit card with them, so I will buy it there.

Once you convert to silicone you are married to it. Still patchable but once coated you need to patch with a silicon based product. If you are coating over black or fresh patching it is recommended by most silicone manafactures I have worked with with to prime it first to prevent the asphalt based products from bleeding into the silicone.
