$26 per tube?????!!!!

Yep, Canadian pricing.

Kerdi-fix alternative?

I found the following post on the John Bridge site ...

" Kerdi Fix is "Silyl-modified polymer" or SMP

According to the Schlueter Shower guide where it says:

Adhesive/Sealant
Any protrusions through the KERDI
membrane must be treated with Schluter®
-KERDI-BAND and Schluter®-KERDI-FIX, or
equivalent sealant, to ensure a fully
waterproof assembly.

Basic raw material Silyl-modified polymer (SMP)

So, a search in Google shopping turned up a Bostic marine product (10 oz) based upon Silyl Modified Polymer (SMP) Technology that looks similar on sale for $6.91.... Bostik Marine 940 FS

So, would it be wrong to use such a thing? How does one define "Equivalent" The posted properties of the sealants look pretty identical (at least shear strength, although the material is not specified...)"

What would be wrong with using another manufacturers product? Warranty issues?

Yeah, I would say Warranty would be the biggest issue. Plus, who knows what will happen to the foam core using some other brand. It may do something odd like melt it, or crystallize the edges or something else that may open up and leave a gap.

I have just stumbled onto the Kerdi board product and I am intrigued. I use the Kerdi membrane now, but would love to save the labor by using the board. Does anyone know of a supplier of that product in the SE U.S.?

It's supposed to be released in April, as soon as they get all the approval certifications.

Any dealer who sells Schluter products can order the material if they don't stock it.

Thanks! I have several dealers here that supply Schluter products, so I will alert them to let me know when the board is out.

Harry where did you buy ther Kerdi board? I tried Tile Master in Aurora and they still don't have it yet. Anyone know where and when it will be available in the Toronto area? Thanks. FYI Bostik 940FS is available on Amazon.com for about $120 for a case of 12 tubes.

I would look into the Bostik's 70-03A sealant, the similarities are pretty shocking !

Brenda,

Thank you for wasting our time with that link. Can you find something useful to do with your life?
