Few projects in life are as satisfying as restoring an older home to its original glory. But if your restoration involves the removal of old linoleum, the project quickly becomes extremely challenging. Taking up old linoleum and removing the adhesive is a huge job, but there are steps you can take to make it a little easier. The age of the linoleum and the type of adhesive can certainly make your job more difficult. Some people simply lay the new floor over the old linoleum, while others dig in with tools and plenty of elbow grease to get the job done.
To start with, it's unlikely that you'll be able to just remove the linoleum and adhesive all at once. What's under the linoleum can be part of the problem, especially if it's wood. Concrete floors can withstand a lot more in the way of rough treatment, including the type of scraper you use. Most people will use paint scrapers, although scrapers with a razor blade are usually more efficient. Be ready to break some blades it if the adhesive is hard, and you're working on concrete.
Don't try to remove everything at once. Instead, try cutting the linoleum into strips or sections, and peeling them away. You should be able to remove most of the surface layer and a good portion of the linoleum backing. Using this method also makes it a lot easier to get at the underlying adhesive.
When the top layer is removed and you're down to bits of adhesive, it's time to get scraping. There are a few options to clean away the old glue. According to consumer reviews, Krud Kutter and other chemical solvents can make the job easier. If you decide to use any of these products, make sure that you read the instructions carefully. Be sure to wear gloves and a ventilation mask. Work one small area at a time before moving on to the next.
Other home repairers report success with using nothing more advanced than boiling or very hot water. The water can be poured directly on the backing and adhesive, a small area at a time, left to soak, and then scraped up. Alternatively, you can fold an old towel and lay it on top of a section of adhesive, pour boiling water over it, let it set, remove and then scrape.
Direct heat is a great way to soften old linoleum adhesive. Find an inconspicuous area of flooring, and use a hair dryer and putty knife to scrape away the glue. On hardwood floors, you must push the scraper in the same direction as the natural grain of the wood, or you'll be left with a damaged floor. Keep a durable pan nearby to hold the scrapings, and be sure that it won't melt or burn if it comes in contact with the heat source or hot materials.
A heat gun can be a great tool in removing old linoleum adhesive. You'll need to be careful not to scorch or char the wood. It's also important to know that this method can cause softened adhesive or mastic to creep into any of the natural crevices and the cracks between floorboards. Work a very small area, with a constantly moving heat source. Scrape as quickly as possible for best results.
It's almost impossible to remove every bit of old adhesive from a hardwood floor, and excessive scraping will most certainly damage the wood. Remove as much as the adhesive as you can by using these methods, and then clean the floors. Take a look and consider your nest step. A light sanding may be in order, or you can try scrubbing the remaining residue away with rags and solvent. Turpentine and mineral spirits can get the job done. If you're planning to lay a new covering over your cleaned wood floor, do yourself a big favor and remember to seal the wood before applying the new adhesive.
