Q: Do you offer "Aluminum Oxide Finishes" on your flooring? A: Yes, in addition to our exclusive “Anti-Scratch” and “Anti-Abrasive” coatings, we also offer the very hard Aluminum Oxide finishes on some of our product line. That can better protect your floor from normal wear and tear. Because of that we are able to offer 25 years of finish wear warranty* for our products. Eventually the floor will need to be screened and re-coated, or sanded and re-finished. With Aluminum Oxide and our exclusive “Anti-Scratch” and “Anti-Abrasive” coatings, the time between your next sanding will be greatly extended and this will save you money. Q: Does my floor change color? A: Like fine wine, all wood will “age” (darken) over time. The special UV cured finishes we use are hard and durable but it IS sensitive to UV Rays. Prolong exposure to sunlight will slightly discolor the floor. Q: What type of cleaner should I use on my floor? A: Cleaning your floor is easy. Any type of good urethane finish wood cleaner is acceptable from your local Home Improvement Centers. Never use any wax or cleaner that must be mixed with water such as oil soap, lemon oil, sprays, and liquid wax as this will damage the coatings and result in the loss of warranty. Please follow the manufacturer’s instructions. Q: What should NOT be used on pre-finished floors? A: Water, wax, furniture polish and any other cleaner with wax in it. Q: What do you mean by Glue down and Nailed down? A: Glue down and nailed down are methods used to install wood flooring. Glue down is the act of using flooring adhesive to glue the flooring to the sub-floor, used mainly for installations over concrete slabs. Only engineered materials can be glued down. Engineered floor also can be staple down or both glued and nailed to wood sub floors. All of our solid materials require the floor to be nailed down to the sub-floor using flooring nails (not staples). Q: What type of finish does "Ark" Flooring have? A: Ark floors finish consists of seven (7) layers of high-grade Acrylic Urethane. Our exclusive “Anti-Scratch” and “Anti-Abrasive” Coating protects the planks from normal abrasion and minor scratches.
