Checking out the new Dicor Butyl Rubber Sealant

In this video I compare the original butyl/putty tape application to a new product on the market – Dicor Butyl Rubber Sealant. I share my initial thoughts and the pros and cons of this new product.

P.S. Before you ask, no – that isn’t me on the tube! It’s actually “Rudy, the Dicor Products Answer Man.” (Well, he’s actually busy actor/model Gary Dellmo.)

Dicor Butyl Rubber Sealant

  • Can be used on skylights, vents, windows, and termination rails.
  • Adheres to TPO, EPDM, PVC, glass, metals, aluminum, concrete, wood and some plastics.
  • Boasts a mess-free easy application and is UV resistant.
  • Cures to a putty-like consistency.
  • Creates an airtight, strong seal that resists degradation.

Below is a list of the products we used during the repairs in this video:

My only concern with this new product is the one I have with all caulks; once you use them, that’s it. Next time you try to use them the nozzle has caked up with dry sealant no matter what you’ve done to cap it off. My roll of butyl tape is always ready.

We had a bedroom window ‘fixed’ by a mobile repair guy. It was leaking like a seive when it rained – in Houston. The repair guy removed the window and used some sort of ‘goop’ out of a tube like this video to seal the window when he replaced it. I was surprised to see he didn’t use the usual roll of sealing tape for the job. Next time we had serious rain, the window still leaked only not as bad. We were no longer in Houston so we couldn’t contact the original tech. We contacted our favorite tech at home and he came over and fixed the window with a roll of the familiar tape. No problems since. For windows, I don’t think you can beat the old standby.

From what I gathered, this is used mainly for the roof and self-leveling is for lateral application. The repair guy probably used a different product when he repaired your window. As a footnote, I always ask for their business card or request an invoice for practical reasons.

We’ve used this repairman several times and he’s always done great work. I questioned him on his sealing choice and he said this stuff was far superior to the usual ‘tape’. I took his word for it. In this case, he was wrong. While this was a ‘points off’ incident, his previous good work still makes him our go-to repair guy – just not for windows . . .
