To keep your retracting tape measure working smoothly wipe the metal blade with a small dab of car wax, then wipe with a clean cloth. This will help protect the blade's finish and keep it retracting smoothly.
When purchasing carpeting, you should buy the best-quality carpet you can afford, coupled with the highest quality padding. In fact, the padding that goes between the carpeting and the subflooring is as important as the choice of carpeting itself. Padding provides softness and support, cuts down on noise and insulates the floor. Often referred to as “underlay” or “cushion,” padding thickness depends on the pile of the carpet above it. Padding should be no thicker than 7/16 inch, even for a very deep pile carpet. Too much cushion can actually void a manufacturer’s warranty; so, take the time to find the padding that is right for your new carpet.
