You should consider taking a look at whether you prefer a finish that is applied on the job-site, or a flooring product that is finished at the factory.
If you choose acrylic impregnated flooring, you need not consider these options, because acrylic impregnated flooring is always finished at the factory, however, they can be refinished like any other hardwood flooring.
A job-site finish is one that is applied at the place of the installation. There are several different types of finishes available and, when you choose a job-site finish, they are probably all available to you. Most ( but not all ) solid wood products are unfinished, and some laminated/engineered products are available unfinished.
Choosing the type of finish to be applied to your floor on-site gives you the choice of what type of shine you prefer, as well as the effect the color of the product will have on your floor. A wide range of stains/colors are available for use on a floor that will be finished on-site, giving you unlimited possibilities for customizing your floor’s color. However, sanding and finishing on-site does create dust and noise from the equipment, and there is a drying time during which you will not be able to use that particular room.
A prefinished floor is one on which the finish is applied at the factory. Most ( but not all ) engineered products are prefinished, and today many more solid products are available pre-finished than ever before.
Several finish options are available in prefinished products, including ultraviolet cured urethane, water-based urethane, moisture-cured urethane and seal and wax. You should consult your wood flooring professional as to which finishes are available on the product of your choice.
Prefinished flooring eliminates the dust and noise factors involved in the job-site finishing process, however, your finish and stain options are more limited.
