Creating rounded edge where garage floor meets stem wall before epoxy.

[Arkive]

I prefer a rounded edge for ease of cleaning and preventing crevices for liquids and dust to hide. Attached images shows the profile I'm after if there's any confusion. While I'd like to go with the simplest/cheapest option, my big concern is ensuring an epoxy coat will properly bond after installation as I will be carrying the epoxy up the stem wall. Thanks in advance.

So are you planning on creating this radius with an epoxy?

I had to do this once. I bought a cheap straight edged trowel ( https://www.homedepot.com/p/Bon-Too...7b&gclid=CPOwuNasuuMCFVDZDQodqUQFTg&gclsrc=ds ) and ground the radius I wanted into one corner . With a 6" drywall knife I laid a row of thinset into the corner, then pulled my trowel along the floor and wall, creating the desired cove detail. As the thinset starts to set up you can go back with a damp sponge and clean / dress it perfectly.

Vdrsnk, my goal was to avoid wasting epoxy on this chore.

Toolfool, this is exactly the right answer. Thank you.

Hi
This is what we refer to as a 'cove' and we carry Cove Mortar and curved Cove Trowels to make them. These are used and often required in commercial kitchens and labs and operating rooms. Also sometimes specified in public restrooms. The purpose of the coves is to allow for easy cleaning and no bacteria building in a hard-to-clean 90 degree angle vs a curve. Usually not ever needed for residential work unless you want it.

Cove Mortar is specially formulated to make coves and is an epoxy/aggregate blend. No liquid alone will do what you want.

You would apply duct tape about 4" above the floor for a clean edge, then mix up the mortar and apply to floor edge/wall, make the cove with the Cove Tool, remove the tape, let that cure, and then do the floor onto the lower part of the cove. It's not easy work for a novice and does require a bit of technique and training to get them 'right'.
