The rounded profile removes the square corner where dirt builds up, and the smooth, non-porous surface is easy to clean. Installers usually glue a rubber cove base to the wall, so it depends on the adhesive behind it. This guide looks at replacing it with rigid PVC. On the job site, the CoRound™ system offers three things. No sealant line required along the wall. Pre-formed corners, no silicone-filled field cuts. No resin or cement to cure.

How Does a Rubber Cove Base Stay on the Wall?
A rubber cove base usually comes in rolls or in lengths. On site, the installer spreads cove base adhesive on its back. Then they press the base against the wall, and the adhesive holds it there.
In contrast, the CoR Skirt is screwed or riveted to the wall, or bonded with adhesive: installer’s choice. In other words, the installer can use adhesive on the CoR Skirt, but does not have to.
How Is a Rigid PVC Sanitary Base Made?
CoRound profiles are precision-extruded from rigid PVC, with flexible co-extruded lips on the cove base and the sanitary base. So the body is rigid, while the lips are flexible.
At the floor, flexible co-extruded lips press against the wall and the floor and follow small surface irregularities, closing the juncture.
How Does a Rigid PVC Cove Base Handle Corners?
Straight lengths meet at a joint piece, columns take pre-formed outside corners, and each run stops at an end cap at the door: no miter cuts to fill with silicone.
For example, at the floor, the CoR Skirt S of the CoRound Seal line has these pre-formed pieces:
- 3-way internal corner: where two CoR Skirt runs and the vertical CoR 4 meet.
- 2-way internal corner: for two CoR Skirt runs, where there is no vertical cove base.
- 2-way external corner: for columns and outside wall corners.
- Joint: for two CoR Skirt lengths in a straight run.
- End caps, right and left: where a run stops, for example at a door.
What Does “No Sealant Line Required Along the Wall” Mean?
On ribbed panels, a metal base usually needs a bead of sealant along the wall: a second step, and exposed sealant can turn dark and attract dirt over time, leaving a dark line between a white wall and a white base. With CoRound, no sealant line is required along the wall.
Moreover, on standard cold storage panels with mesa or wide-rib profiles, the flexible lip follows the ribs. As a result, the flexible lip minimizes gaps along the wall, with no sealant line required.
How Do You Replace a Rubber Cove Base With the CoR Skirt?
In general, the installer removes the old base first. Then they check the wall behind it before installing the new profiles.
After that, the straight lengths go on the wall. Finally, corner pieces, joints and end caps press or snap into place.
CoRound installs on insulated panels, FRP-covered walls, tile, masonry and drywall. Tools: tape measure, level, drill and a cutting tool. These instructions are general installation advice: the installer chooses the method that suits the job.
Which CoRound Line Fits Your Project?
The CoR Skirt comes in two lines. CoRound Basic for cost-sensitive projects; CoRound Seal adds corner pieces and end caps with flexible lips.
The CoR Skirt S comes in Pure White 9010 and Sand White 9002. The CoR Skirt B also comes in Stainless Steel Gray 9023. Then compare the CoRound Seal System and the CoRound Basic System in our shop.

Frequently Asked Questions
Do you need silicone when you install CoRound?
Silicone is optional: not required for installation. However, for the CoR Skirt, in wet areas, installers can add a thin bead of neutral silicone to help keep water from getting behind the profile.
Do you need a separate flooring crew when you install CoRound?
The panel crew can install the profiles: no separate flooring or welding crew to schedule.
Can I see the profiles before I order?
Yes. Free samples are available on request: email [email protected] and list the profiles you need.
