What is a Stubbi Cove Roller?

Stubbi – Over-engineered, endorsed, worlds first, cove fillet embedding tool for professional flooring installers

If your hearing the the words ‘Stubbi’ or ‘Cove roller’ getting thrown around a lot lately, there’s a good reason for that!

Commercial vinyl layers are seeing mass improvements in the quality of craftsmanship using the Stubbi flooring tools professional range.

The Stubbi® is a innovative tool designed to assist in the art that we in the trade know in as ‘cove forming’.

Specifically designed for the commercial flooring industry of Australia, this adaptable roller has been built with the harshness of its environment in mind. It has been over-engineered to go the distance and is proving to become an essential part of the kit for vinyl installers around the world.

Over-Engineered with the harshness of the Australian climate and the brutality of the flooring world job site in mind

The innovative design supersedes conventional hand rollers is this field due to the dual radius profiled head, smoothly carried on its axis by twin ball bearings, making it a worlds first for lateral pressure contact during cove forming.

If we look at Australian Standards for resilient floor coverings, they state that “coved floor coverings shall be fully supported by a solid backing”.

By adhering to this method we actually remove the liability of movement completely between the connecting components, driving the cove fillet deeply into the juncture, embedding it firmly as manufacturers recommend, fully supporting the vinyl at its weakest point, the curvature of the skirting riser.

This also ensures that full contact adhesion of the sheet material and the cove fillet will occur using the pre and post rolling process, removing any liability of movement that causes weakness in the perimeters.

Vinyl flooring coving failure, allows debris, fluids, and bacteria affect the adhesion of the sheet material

A simple 3-step process eliminates cove failures.

1. Pre Roll – Stubbi Rolling of coving strip into adhesive at wall / floor juncture

2. Installation – Stubbi Rolling of vinyl sheet product firmly onto cove former strip at base level

3. Post Roll – Stubbi Finishing rolling of installed vinyl product neatly into curvature and wall risers

After cnc digital Precision machining of the components, each Stubbi Roller is rigorously assembled by hand, one unit at a time.

‘Patent Pending’

Innovation and design

We are also reminded that the preferred method of installation is of external corner butterfly joints and welded seams ‘up off’ the floor surface.

This also creates stress in the vinyl due to its resilience and can leave installers facing air pockets and undulations in the coved perimeters, which will later go on to lead to product failure.

Now, with the aid of the Stubbi® we can achieve a full contact bond around all perimeters reducing the need to add heat to the sheet material during the installation.
