Stop Grouting Your Shower Perimeter Joints - Enough is Enough

DO NOT let your contractor just grout your shower perimeter joints. It’s TCNA standard to use a flexible 100% silicone sealant at those perimeter joints. Also need to leave a sufficient expansion at those areas for thermal cycling.

Thank you! My tile supplier mentioned this too.

Love this video ! Thank you for the idea of doing it first before the grout

Glad it was helpful!

It should be grout first then silicone sealant on top right?

[@Californiaflooring]

No, 💯 silicone only

[@rica.7370]

The video says silicone first then grout on top. Now that's really strange!

[@Californiaflooring]

@@rica.7370 Negative, I do not say grout on top. Listen to it again.

I like the idea of doing movement joints first so you don’t accidentally get grout in there. I wonder why ANSI specifies grout before silicone?
When should the sealant be applied?
ANSI A108.02 - 4.4.5 states, “Install sealant after tilework and grout are dry. Follow sealant manufacturer’s recommendations.”

@@nonamuss9991 you can do it that way also, you have to remove the backer rod when the grout is fresh, and install new backer rod before before you apply silicone.

naw. come back in 6 months and you'll see mold growing all over your caulk joints.

Nah knucklehead, it’s 100% silicone, not acrylic or cementitious grout. Also you need to understand TCNA and NTCA
