Dicor on roof

[rdickinson]

The GPS puck for the Sat system needs replacing and the holes thru the roof where it plus some other cables enter the unit are covered with a puddle of what looks like Dicor self leveling compound.

 

Maybe one of those saws they use to remove casts from one of many breaks I've encountered. They cut the cast but have never cut my skin.

 

The roof is rubber.

 

What is the best and safest way to deal with this?

 

I figure to use the existing cable taped to pull the new one thru, depending on how big the hole is. If not big enough a snake or coathanger.

 

Thanks.

I went at a large patch on my rubber roof with a hooked blade linoleum knife and a putty knife. When I used steady pressure that seemed to work best. I took the bulk of the buildup off, and exposed clean compound, plus any voids or cracks.

Then I went over it with fresh compound hoping the new stuff would adhere to the old stuff.

A heat gun would speed up the process I think.

What Sculptor said is the way I generally do it. Use a heat gun and a stiff plastic putty knife. Or if you are careful, a painters scraping tool. The heat is the key. Don't burn up the roof, though.

An alternative to the Dicor would be 3M 5200. 5200 is more UV stable and doesn't break down as easy. But it is "Permanent". There are different versions, Slow cure, Fast cure, etc.

I have used a cordless multi tool with great success.
