Great stuff. Great strength.
By Stan from Ann Arbor, Michigan

I have used this to bond sheet steel to sheet steel. It is awesome. I'll use it to bond the panel anchor strips to my Jaguar XKE bonnet. My test strips (after 3 years) are as solid as ever. The Sika 252 is forgiving and easy to work with. It holds paint really well (automotive). Use a high-leverage caulk gun (yes they cost more, but you will thank yourself) and you will have no problems dispensing the Sika.

Bottom Line Yes, I would recommend to a friend

Works well. Hard to use.
By Solar man from California

The product holds well but is hard to squeeze by hand through a caulking gun. So I found it difficult to lay a good bead.

Bottom Line Yes, I would recommend to a friend

I would buy it if I needed it.
By Chuck from Moss Landing, California

Verified Purchase

Used this to attach two Renogy Cable Entry Housings to a vertical surface. Company suggested it as the only way to attach the housings. They are firmly attached. I used about 10 milliliters of the adhesive. It would be nice if Sikaflex offered a much smaller quantity.

Bottom Line Yes, I would recommend to a friend

Rubber roof surface application Answer
By Freelance from Indian Wells, CA

In a word: PROBABLY would work in rubber roof app. Make sure both surfaces to be bonded are clean and dry. This step is often over looked, and is critical. The solar panel supports we bonded to a wood shake roof were later removed to relocate the panels and were done without damaging the supports or the roof. Held up in temperatures on roof of over 130F and high winds of gusts to 50 mph

Bottom Line Yes, I would recommend to a friend
