A few years ago there was a discussion of resilient base. The opinions varied, but overall seemed to favor field-formed corners. Absent from the discussion was any comment on the material used. My understanding has always been that rubber is best, vinyl worst, and vinyl/rubber composition in between. We'd like to use rubber, but with vinyl being cheaper, that's what we use. (Aren't we supposed to be concerned about life cycle cost?)

This article appears to be a thorough evaluation of the pros and cons of each type. It states, "When properly formed and fitted by the installer on the job, however, outside corners are acceptable and it is not necessary to specify preformed or pre-molded corners" But, for types TPR and TV, "forming corners often results in visible white stress lines or discoloration in the material."

What type resilient base do you specify? Do you specify factory- or field-formed corners? If you have used two or more types of base, or two or more types of corners, how do they compare for appearance and performance? Be sure to indicate the combinations of type and corners used.

Our interior designers preferred to use rubber and to use pre-formed corners for both inside and outside corners. I never got to see the results, but since the designers did, and continued to request the same thing, I can only assume the results were satisfactory.

Sheldon,

I select Type TS, 100 percent vulcanized rubber.

Roppe, Burke, Nora, Allstate, and Flexco manufacture Thermoset Vulcanized Rubber

For outside corners:
Score back of base material with grooving tool, at all outside corners; maintain minimum leg length 18 inches where wall length permits. Mount base so that scored groove is accurately aligned with corner, and with base tightly adhered to wall at both sides of corner, with no visible gaps at top of base. Where cove base is formed around outside corners, stretch toe of cove for smooth transition around corner, with toe in uniform contact with the finish flooring.

For inside corners:
Miter or cope inside corners for accurate fit.

Rubber, as opposed to vinyl, as I was told vinyl tends to shrink more than rubber.
Field-formed corners, as I was told preformed corners COULD be different dye lot and thus more possibility of color mismatch.

My firm has a well informed and very astute interiors department and their consensus echoes what Mr. Yancey and 'guest' have written. We tend to take advantage of the full range of colors offered by the manufacturers and certainly want to avoid mis-matches. For our healthcare projects the superior performance of the rubber product is worth the extra cost.

For many years, rubber was the product of choice for most of my clients. Recently I have begun to see more selection of vinyl base. Some designers like it because it is more glossy (which I think will scuff easier--get your portfolio pictures early).
