Q: I saw a product at a big box store that says it will restore the shine to my floor; I just have to clean the floor and mop it on. Can I do that instead of getting my floors recoated?
There are various products on the market that promise to make your floor look like new without having to actually sand or recoat the floor. These products are usually an extremely thin finish that you can apply yourself. The first thing with such products is to make sure they will be compatible with the finish on the floor and won't contaminate your floor for future recoating. If you know the manufacturer of your finish or your floor (in the case of a factory-finished floor), ask them before using the product.
Second, be aware of typical pitfalls when using a product such as this. You must clean your floor extremely well before applying the product; if you don't, you'll be adhering dirt and debris right into the floor. Also, be aware that, because the product is so thin, it wears off quickly and often unevenly. So, no, products like these aren't anything like the results you would get from having your floor professionally recoated.
