Products : Surface Prep : Cement Backerboards : WonderBoard® Lite Backerboard
A 20% lighter fiberglass mesh-reinforced cement backerboard for residential and commercial tile, stone, slate and thin-brick applications. High-flexural strength, along with moisture resistance, makes WonderBoard® Lite ideal for both interior and exterior substrate applications. WonderBoard Lite meets the performance standards of ANSI A118.9.
American National Standards Institute (ANSI) ANSI A108.11, A118.9, A108.5 and A118.4 American National Standards for the Installation of Ceramic Tile ASTM International (ASTM) ASTM C1325

This product, when cut, drilled or abraded, produces dust containing free silica, which may cause cancer or delayed lung injury (silicosis) if inhaled. Work outdoors, in a well-ventilated area, or use mechanical ventilation. Wear safety glasses and a dust mask; in very dusty areas or where airborne dust exceeds PEL, wear a NIOSH/MSHA approved respirator. This product contains one or more chemicals known to the State of California to cause cancer.
For the subfloor, securely glue and fasten minimum 5/8" (16 mm) exterior grade plywood or OSB panels (PRP-108) to the floor joists. Floor joists should be spaced a maximum of 16" (40 cm) o.c.; a 3/4" (19 mm) Exterior Grade Plywood or OSB subfloor with I-joists spaced a maximum of 19.2" (48 cm) o.c. is also acceptable. When setting dimensional stone larger than 12" x 12" (30 x 30 cm), a 3/4" (19 mm) non-deflecting subfloor is required. All plywood or OSB subfloor sheets must be gapped 1/8" (3 mm). Use 1" (2.5 cm) bond-breaker tape over gaps in the subfloor to prevent gaps from filling with thin-set. Using a 1/4" (6 mm) square-notch trowel, apply a setting bed of polymer-modified mortar to the subfloor. Immediately laminate the WonderBoard® Lite to the subfloor, leaving a 1/8" - 3/16" (3-5 mm) space between the boards at all joints and corners. Stagger joints so they do not line up with underlying substrate joints. While the setting bed mortar is still workable, fasten WonderBoard® Lite every 4"- 6" (10-15 cm) o.c. throughout the board field and around all edges. Around the perimeter of each board, locate fasteners within 1/2"-1" (1.3-2.5 cm) of the edge. Fill all joints with polymer-modified mortar. On all joints and corners, prefill the gap with bonding material; then embed 2" (5 cm) mesh tape and smooth material over the joint and corner.
Walls and Ceilings
For wall framing, edges parallel to framing should be continuously supported (typical sleeper studs should be used). Framing for a tub surround or prefabricated shower pan should be plumb and square. Provisions for the sheet membrane pan liner must be made to ensure proper backerboard installation at the interface of the tub or pan flange. For ceiling framing, the complete ceiling assembly allowable deflection due to dead load should not exceed 1/360 of the span. Framing members in the walls and ceiling should not exceed 16" (40 cm) o.c. The weight applied to the walls and ceiling frame, including insulation, backerboard, bonding material and facing material, should not exceed 15 lb/ft (73 kg/M). Backerboard edges parallel to the framing should be continuously supported. Provide additional blocking, when necessary, to permit proper backerboard attachment and reduce deflection between the joists. Leaving a 1/8" 3/16" (3-5 mm) space at all joints and corners, install the WonderBoard® Lite panels. Stagger board joints with those of adjacent rows. Fasten the backerboard every 6" (15 cm) along the joist or rafter. It is recommended that blocking be installed between the joists to support the ends of the backerboard. On all joints and corners, prefill the gap with bonding material, and then embed 2" (5 cm) mesh tape and smooth the material over the joint and corner.
A moisture barrier must be installed to protect the wall cavity for wet area installations. Nail or staple 15 lb roofing felt or 4 mil polyethylene sheeting to the studs. Precut WonderBoard® Lite panels and make any necessary cutouts. Install WonderBoard® Lite, leaving a 1/8"-3/16" (3-5 mm) space at all joints and corners. Stagger board joints with those of adjacent rows. Fasten backerboards every 8" (20.3 cm) o.c. along studs. At all joints and corners, prefill gaps with polymer-modified mortar, then embed 2" (5 cm) alkali-resistant fiberglass mesh tape and smooth material over joint and corner. Any shelf, ledge or horizontal surface subjected to water exposure must have a slight downward slope for water runoff. These areas also require proper waterproofing. Apply RedGard® according to directions.
For installation of tile, natural stone or a similar material, comply with ANSI A108 standard specifications. Install according to installation instructions for the corresponding mortar data sheets.
Properly installed product requires no special maintenance.
