While these finishes are marketed to the consumer to withstand almost anything, contractors are left with the challenge of trying to abrade them for recoats. This isn’t impossible, as many believe, but there are special techniques and equipment that can make the daunting task a little easier.Many factory-finished hardwood floor manufacturers are touting warranties that last longer than the Ice Age. It’s important that the home owner understand that these are “wear-through” warranties and not “look-bad” warranties. It’s true that today’s finishes are tougher than ever, but they are not impervious. The floors are abrasion-resistant, not abrasion-proof. Traffic patterns and other wear marks can still appear in the finish. The floors also can be susceptible to moisture and stains. This means that many customers will want to have their floors recoated during the warranty period. The problem is that part of the manufacturer’s warranty will be invalidated once the floor is refinished. The best bet is to contact the manufacturer and get the warranty specifics before you do any work on the floor. If the customer still wants the floor recoated, be sure she understands that the warranty will probably be null and void once your abrasive or finish touches the floor.December 31, 2000Previous PagePage 3 of 3Top StoriesRetailThriving Through Innovation: See the Winners of the 2025 WFB Outstanding Retailer AwardsFrom reimagined showrooms and mobile studios to thoughtful mentorship, employee empowerment and social media marketing, these WFB Outstanding Retailers are proving that personalized service is key to long-term success.TechniquesUseful Advice When Dealing With Pine FlooringContractingHow I Do These Jobs: Refinishing DecksNewsRecognizing Wood Floor Contractors: Enter the 2025 Ultimate Wood Floor Guy/Gal ContestSponsor Content3 Things to Do in Uncertain Financial Times
