Take into account the trade-offs in effectiveness, security, and velocity when choosing a stripper. Learn the labels on all of the merchandise you employ very fastidiously.
**Scrapers and brushes** are used with chemical strippers. A great high quality scraper is significant to take away the softened **polyurethane**. Select scrapers with replaceable blades for ease of use. A plastic scraper is ideal for gently getting below the coating. For making use of the stripper, a brush with pure bristles is usually really helpful.
**Sandpaper and metal wool** are important for smoothing the wooden and making ready it for refinishing. Sandpaper grit choice is important. For preliminary sanding after stripping, begin with a rough grit (round 80-120 grit) to take away any remaining traces of **polyurethane** and stage the floor. Progress by finer grits (150, 180, and 220 or increased) to realize a easy end. Metal wool can be utilized for remaining sprucing and eradicating imperfections.
**Cleansing cloths** are essential for eradicating the dissolved **polyurethane** and chemical residue. Microfiber cloths work properly, however any clear, lint-free material will do.
**Solvents and Cleaners** are used to scrub the wooden and guarantee all traces of the **polyurethane** have been eliminated. Denatured alcohol is usually used after stripping, however mineral spirits could also be extra applicable relying on the stripper.
Strategies for Eradicating Polyurethane: Selecting the Proper Method
There are a number of strategies for **eradicating polyurethane**, every with its benefits and downsides. One of the best technique depends upon the kind of **polyurethane**, the scale of the mission, and your preferences.
**Chemical Stripping:** This technique includes making use of a chemical stripper to the floor, permitting it to melt the **polyurethane**, after which scraping the end away.
