Ceramic tile must be set in a mortar bed. For ceramic tile applied with an adhesive, the edges of the sub-floor must be supported by means of tongue-and groove panel edges or blocking. In either case, underlay is recommended. Plywood or OSB sheets at least 6 mm (1⁄4 in.) thick commonly serve as underlay and particleboard may also be used. Ensure that the particleboard is approved for use with the finished flooring material by checking the manufacturer’s installation instructions. Attach the underlay to the subfloor with annular grooved nails spaced not more than 150 mm (6 in.) apart along the edges and at 200 mm (8 in.) centres in both directions over the rest of the panel. Use nails at least 19-mm (3⁄4 in.) long for 6 mm (1⁄4 in.) sheets and at least 22 mm (7⁄8 in.) long for 7.9 mm (5⁄16 in.) sheets. Staples or screws may also be used. Fill joints between the underlay and any surface defects with non-shrinking filler compound that will bond to the underlay. Sand the filler smooth after it has set.
WOOD STRIP FLOORING Wood-finish flooring is widely used in living and dining rooms, bedrooms and hallways. Hardwoods such as birch, maple, beech and oak are used in a variety of widths and thicknesses as strip flooring. Vertical-grain softwoods such as fir or
hemlock are sometimes used. The flooring may be stained and finished after installation or it may be factory finished. Wood-strip flooring, which is manufactured in various widths and thicknesses, comes in several grades and is bundled in random lengths. Strip flooring looks best when laid lengthwise in a rectangular room. The tongue-and-groove strips are profiled on the back to control cupping and checking. The top face is slightly wider than the bottom so that when the strips are driven together the upper edges touch, but the lower edges are slightly apart. A tight fit is necessary to avoid squeaks. Wood strip flooring should not be brought into a house until the concrete in basements has cured (shed moisture) and the gypsum board finishing has been completed so that the house humidity level has moderated. The flooring should be kept in a warm, dry place until it is installed. If installed with a high moisture content, it will be prone to shrinkage as it dries and may develop openings between the joints. Various types of nails, including annular and spiral-grooved types, are used to attach the flooring. Minimum nail lengths and nail spacing are listed in Table 42 (p. 309). Staples applied with manual and pneumatic tools are also used. Many installers use a mallet-driven nailing tool that drives the nail in the proper location, at the correct angle, and sets the head to the proper depth.
