The rounded profile removes the square corner where dirt builds up, and the smooth, non-porous surface is easy to clean. A peel and stick cove base stays on the wall with the adhesive on its back. So, 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.

What Holds a Peel and Stick Cove Base in Place?
A peel and stick cove base comes with adhesive already on its back. On site, the installer removes the liner and presses the base against the wall. From then on, the adhesive is what holds it there.
In contrast, the CoR Skirt is screwed or riveted to the wall, or bonded with adhesive: installer’s choice.
How Do You Replace a Peel and Stick Cove Base?
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. Then, corner pieces, joints and end caps press or snap into place.
Tools: tape measure, level, drill and a cutting tool. These instructions are general installation advice: the installer chooses the method that suits the job.
Why Does the Wall-Floor Juncture Matter?
Square corners can trap dirt and water, and that is where bacteria can grow. A rounded profile leaves fewer of those spots and makes them easier to wash out.
FDA Food Code §6-201.13 requires floor and wall junctures to be coved and closed to no larger than 1 mm (1/32 inch) where floors are not cleaned by water flushing, and coved and sealed where they are. Check requirements with your local health department.

What Else Does the CoR Skirt Offer?
To begin with, when the CoR Skirt is screwed or riveted, the fasteners sit behind a snap-on cover strip: no exposed screw heads to collect dirt.
In rooms built with insulated panels, for example, the CoR Channel works as the base track. The CoR Skirt snaps into it.
In addition, the CoR Skirt comes in two lines. CoRound Basic for cost-sensitive projects; CoRound Seal adds corner pieces and end caps with flexible lips.
What Happens at the Floor?
At the floor, flexible co-extruded lips press against the wall and the floor and follow small surface irregularities, closing the juncture.
Also, 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.
What Happens at the 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.
Why Choose a Rigid PVC Cove Base From Panelmart?
- No sealant line required along the wall: one less step on site and, as a result, one less cost that can recur.
- Pre-formed corners, no silicone-filled field cuts: joints, 90° inside and outside corners, and end caps.
- No resin or cement to cure: there is nothing to mix, trowel, weld or cure.
- One system for the whole room: base track, sanitary base or heavy-duty curb, cove base for wall and ceiling junctions, pre-formed corners, end caps and corner guards, all made to fit together.
