Product ID: TDS-451
VersaBond® Lite offers all the performance of Versabond®-LFT with maximized creaminess and the benefits of a true lightweight mortar. This high bond strength formula is 30% lighter than a traditional mortar, resulting in a product that is easier to trowel and move around the jobsite. Designed for a wide variety of interior and exterior floor and wall installations, Versabond® Lite is excellent for setting large and heavy tile or stone. VersaBond® Lite will not sag on walls and offers nonslump performance for floor installations. Capable of LHT thin-set applications up to 3/4″ (19 mm) thick on horizontal surfaces after beat-in. Formulated with CustomLite® Technology, a 35 lb. (15.9 kg) bag covers the same area as a 50 lb. (22.7 kg) bag of traditional mortar. Contributing to LEED® certification, VersaBondLite® contains up to 16.5% recycled content by weight and 2.5% recycled content by volume. Exceeds ANSI A118.4HET, and A118.11 without the need for additives.

*IMPORTANT NOTE: Custom Building Products does not recommend the use of a 1/2" x 1/2" x 1/2" (13 x 13 x 13 mm) Square-Notched trowel as the ½” spacing between each square notch has been shown to make it more difficult to bed tiles and achieve proper mortar coverage. CUSTOM recommends the use of a trowel design that promotes mortar ridge collapse such as either a deeper, slanted, U-notch, V-notch, or ridged large format trowel when applying thicker amounts of mortar to accommodate tile warpage and back pattern recesses. Applying mortar using a 3/4" × 9/16" × 3/8" (19mm × 14mm × 9.5 mm) U- Notch at a 300 angle provides better coverage between the tile and the substrate and the same coverage area as a ½” notched trowel.
Regardless of the trowel used, mortar coverage between the substrate and tile underside is required to be ≥80% for dry areas and ≥95% for wet areas and exteriors with all tile edges properly supported with mortar and in a minimum of 3/32” (2.38 mm) and a maximum of ¾” (19mm) continuous thickness. Note: Larger tiles, tiles with deep underside patterns and ungauged natural stone tiles may require larger notch sizes and may need to be flat back-troweled (formerly back buttered) or notched-back troweled to achieve proper coverage and mortar support. To meet warranty requirements, CUSTOM recommends testing to confirm adequate bonding mortar coverage.
When back troweling, consider the tile’s underside pattern and depth to estimate thickness and usage to add to your estimate. For achieving proper mortar coverage see the following video: Trowel & Error. (Also available in Spanish and Russian.)
