What is Epoxy?
Unlike many other adhesives and fillers that require drying time, epoxies require two parts that, when mixed, begin a chemical reaction that causes the liquid or putty to harden. The amount of time you have to work with the two part epoxy resin before it sets up is determined by the chemistry of the hardener. For tiny jobs, you can choose one-minute epoxy, but in general, epoxy that takes longer to set also forms a stronger bond, not to mention giving you more working time.
Repair Chipped Furniture
When it would be difficult or impossible to replace missing veneer or chipped furniture parts with real wood, epoxy putty makes a great substitute. Two-part putty in a Tootsie Roll shape is convenient to use and makes a strong repair. Just slice off a section and knead the chunk until the two parts are blended and the color is consistent. Then form the putty into approximately the right shape and press it into the damaged area. Use a wet putty knife to smooth and shape the putty. When the epoxy has hardened to about the consistency of bar soap, carve or scrape off most of the excess. When it hardens completely, you can sand it just like wood.
