Water - Wet mopping or excessive water causes wood grain to raise and the wood to expand, crack,splinter and possibly, in extreme cases, to discolour or mildew.
Oil Soaps - Do not use Pledge, Future, Mop & Go and Brite or other household polishes. Such products will harm the long-term performance of your floor.
Ammonia Cleaners - Do not use any ammonia based cleaners because they will dull or damage the floor.
High Heel Shoes - Heels that have lost their protective caps or shoes with any sharp exposed nail or stone will exert up to 8,000 lb per square inch of pressure on a floor. Thats enough to damage any floor.
Sunlight - Exposure to the sun and its UV rays can cause wood floors to fade, change colour or experience surface checking and even cause colour changes if finished with a protective polyurethene.
Squeaks on recently installed floors, chances are there was an error with the installation allowing movement in the subfloor or flooring. There could be many causes, improper subfloor material, incorrect construction of the joists allowing the floor to move. The wrong fastener schedual either too few or too many can cause a loose floor. Applying the wrong type or amount of adhesive could cause the same problem. If the subfloor was not level when flooring was installed, there could be high or low spots in the flooring, which could also cause the noise.
Depending on the severity of the squeaks, you may be able to fix the problem spots by fastening the loose boards from below through the subfloor or on the surface by applying facenails, screws or plugs. If the squeak is prevalent throughout, a complete tearout and possible subfloor repair is the only solution. The best way to prevent a squeaky floor is to make sure that the subfloor is flat within 6mm over a 2.5 m. Also check the weak spots in the subfloor.
