Glue EPDM rubber to roof tile

[erkka]

anyone have good tips on glue or sealant that can handle EPDM rubber against concrete tiles?

Bonding Adhesive is used to attach EPDM rubber sheet to, for example, wood, metal, or concrete

When I google bonding adhesive, it says that it is poor at handling heat and weather exposure. Since I will be attaching it to roof tiles, it is perhaps quite critical that it withstands both high and low temperatures as well as rain, snow, and other conditions.

Sounds strange if Waterlife recommends it for ponds are outdoors year-round...for many years...but it's probably true if that's what it says.

I would have used roof adhesive, that is, bitumen-based, thinking for roofing felt, etc., it must be as tight as possible, so you should prime the concrete.

Yes, a bit strange indeed. It was on this page I read:

Now, this is not really my field, so I'm groping in the dark a bit, but I find it difficult to find a suitable product.

ok! do you think it adheres to rubber? maybe it's easier to just go for trial and error

Is it a product like this you are thinking of:

It is not trial and error. Bitumen and EPDM are compatible and are joined on most tar paper roofs. Google Resitrix, and you will see that they can even be combined into a mat to get the bitumen paper's advantages and EPDM's UV protection. (kind of)

The one you linked probably works, but I'm not entirely sure what differentiates it from what is called roof adhesive that I had in mind, but I can guess that the joint is a bit more viscous and possibly fiber-reinforced to prevent cracking.

Thanks for the response!

What do you think about Icopal's Roof Adhesive?

Probably good but completely unreasonably expensive.

Surely good but completely unreasonably expensive.

Forgot to follow up, but I went with Byggmax asfaltsklister. Seems to work fine. Thanks for the previous answers.
