he first time I unrolled a sheet of flexible veneer I couldn't believe how thin it was. Unlike veneer I've used in the past, it could be bent and rolled without cracking. But the best thing I like about flexible veneer is you don't need to invest a lot of time and money to get professional-looking results. All you really need is - a sharp knife and some contact cement. why use it? For many projects, flexible veneer can be a low cost alternative to solid hardwood or hardwood plywood. You can cover a project with a fancy wood (such as birds-eye maple) at a fraction of the cost it would take to build it out of solid wood. what is it? Unlike standard veneer that's usually V2811 to V40" thick, flexible veneer is cut much thinner — about half as thin. Because it's so thin, flexible ve neer requires a special backing to keep the thin layer of wood from splitting and breaking up. THREE TYPES There are three types of flexible veneer available: paper-backed, pressure sensitive adhesive, and foil-backed, see Drawings below. paper-backed. The most common (and least expensive) type of Unlike veneer I've used in the past, flexible veneer can he bent and rolled without cracking. flexible veneer is paper-backed veneer. As the name implies, paper-backed veneer has a layer of brown paper glued to the back. Because it's so easy to work with, it's my first choice for most veneering projects. psa. Pressure sensitive adhesive (PSA) veneer is commonly referred to as peel and stick veneer. The only difference between it and paper-backed veneer is it has a thin layer of adhesive on the back. The adhesive is protected by wax paper until it's time to be used. Then you just peel off the paper and press the veneer in place. Although there's no glue mess to clean up with PSA veneer, there is one drawback. I've found that the veneer has a tendency to come unglued over time. - foil-backed. Although foil-backed veneer looks just like paper-backed veneer, there is a big difference. Instead of a single backing, there are two layers of paper with a layer of foil sandwiched between them. The foil prevents a lacquer-based finish from dissolving the adhesive. Unfortunately, foil-backed veneer is expensive. And, if the edges are exposed, the foil is noticeable. So I only use it when the edges will be hidden. Or when I know I'm going to finish the project with a lacquer-based finish. Flexible Veneer Paper-hacked. The most common PSA.
