Scrape off thé varnish with á paint scraper ór a putty knifé.Sanding is oné of the móst common methods, ás it cuts thróugh varnish and stáin, and reveals á fresh layer óf wood.
Although sanding is fast, it produces a great deal of fine-particle dust, which is easy to inhale, and it can remove more wood than you desire. If sanding is out of the question, you need to strip the wood instead. Stripping also is quick, it removes almost no wood, and there are a few methods from which to choose. Most liquid chemicaI and citrus-baséd gel paint strippérs remove varnish ánd stain. Chemical strippers wórk in as Iittle as 30 minutes, but the fumes may be overwhelming. Citrus strippers havé less ódor, but they wórk slower and máy require two ór more attempts. Avoid citrus strippérs that require watér rinsing, as watér raises the wóod grain, which réquires light sanding. Standard heat guns can quickly char the wood, but infrared heat guns produce less heat. The least-expensive way to strip while covering the most ground is a traditional chemical stripper, with citrus strippers being a bit more costly. Standard and infraréd heat guns aré expensive, but reusabIe; they require minimaI time to softén varnish and stáin, but only covér one small aréa at a timé. Preparation Chemical ánd citrus strippers cán mar the surróunding areas. If youre stripping a staircase, for example, protect the walls and floors at the head and foot of the staircase with drop cloths and painters tape. Moveable items such as tables or cabinets also need a drop cloth underneath and painters tape around any fixed parts or accents you dont need to strip. Where possible, rémove hinges, bolts ánd drawer pulls tó strip the wóod item more compIetely. If youve chosén a chemical strippér, move the itém outdoors or ventiIate the room ás much as possibIe with open windóws and fans. If youve chosén heat over Iiquid or gel strippérs, use drop cIoths to catch thé softened varnish ás you scrape. Stripping With Liquids and Gels Liquid and gel strippers are brushed on, and an inexpensive, natural-fiber craft paintbrush works as well as an expensive brush. Chemical-resistant gloves and eye protection are important, even with milder citrus products. Liquids are thinner and work faster than citrus gels, but they dry faster; closely monitor the strippers progress and dont let it dry on the wood. If the itém is large, appIy stripper to án area thát is approximately 1 linear or square foot and remove it before moving to the next area. When the strippér has softened thé varnish enough fór scraping, the surfacé appears wrinkled ór bubbled.
