APF Makes Cove Base Installation Easier, More Seamless with
by Ray Gutoski - Sales Representative for Southern California
When you think about flooring projects, most clients spend the bulk of their time focusing on the functionality, design and aesthetics of their actual flooring. Yet, 90% of all floor coating projects have an integral cove base designed into the specification or requested by the end user.
These coves can be designed to specific heights, thicknesses and radiuses, depending on the working environment and cleaning procedures. An integral cove base is typical when installing thin mil, decorative quartz and flake, trowel mortar and urethane cement systems, and is usually sealed with the same material used to coat the floor, creating a seamless and sanitary transition.
To accomplish this most effectively and easily, APF has reformulated its Epoxy 400 Thixotropic material, which can now be used as a cove base gel. This allows the contractor greater flexibility with a simple solution for cove base estimating and installation.
In addition to giving the contractor more flexibility, the Epoxy 400 Thixotropic Cove Gel eliminates job site mixing of multiple components, and the simple mix ratio all but eliminates any job site confusion and associated mixing errors. Because of its simplicity, the formula is easy to estimate. And when it comes to application, the formulation provides an excellent vertical surface primer, creating a consistent solution, which provides a tight seal eliminating multiple grout and/or finish coats.
About Epoxy 400 Thixotropic Cove Base Gel
The Epoxy 400 Thixotropic material is packaged in 1.5- and 15-gallon kits. Each 1.5-gallon kit mixes with 100 pounds of trowel sand or 100 pounds of decorative quartz to create one full kit of cove base material. It is common to split the resin in half to accommodate the 50-pound bags of sand, which are typically sold.
How to Install the Cove Base
As a starting point, contractors should mix the Epoxy 400 Thixotropic resin with a Jiffy Impeller Paddle Mixer for 2 minutes. After the resin is mixed, it should be used as a primer. Then coat the vertical and horizontal surfaces that need cove.
Afterward, mix in the required amount of cove sand with same mixer per the specific instructions. The cove mortar should be applied using a rectangle trowel and finished with a radius trowel designed to meet the height and radius requirements for your project. If needed, a Trowel-Ez formula can be used to help smooth out the mortar when in place.
Following the application, the area should be allowed to cure, after which it’s possible to hand stone where necessary.
