Ok guys, just got a where weird one. My client is ordering glass for a shower build and the manufacturer specifically recommends not using urethane grout in conjunction with translucent glass in a wet area. Opaque glass is fine.

Someone wanna splain it to me Lucy cause that maka no sense to me.

Oceanside doesn't recommend it because water getting trapped behind the tile and not able to escape due to the waterproof nature of urethane, will alter the look of the transparent/translucent tiles.

So in order to use translucent glass I'm forced into cement grout (that they want you to use their $60 sealer). Interesting.

I'm familiar with their recommendations....

I'm trying to make sense of it. If the grout is water proof and glass doesn't absorb water - how's the water going to get behind it in the first place? I mean we're talking about 1x1 glass here.

Oceanside has probably seen enough failed jobs due to sloppy grouting that it won't recommend the newer grouts. But if you carefully pack the joints, I see no reason urethane can't be used.

I use Fusion Pro for grouting. It can be used over mudbed without a sealer according to Customs spec sheet. But, I usually use a some type of membrane anyway.

I can't imagine why they specify not using urethane. It has the same porosity as epoxy. So if olzo's theory (which sounds good to me) is correct, they should also not recommend epoxy too.

I think it's simply grout racism. Call Sharpton.

They don't even have epoxy listed as an option.
