	CEMENTITIOUS UNDERLAYMENT
	Copyright 2005 - 2011 ARCAT, Inc. - All rights reserved
	** NOTE TO SPECIFIER ** Maxxon Corporation; cementitious underlayment. . This section is based on the products of Maxxon Corporation, which is located at: 920 Hamel Rd. P. O. Box 253 Hamel, MN 55340-9539 Tel: (800) 356-7887 Fax: (763) 478-2431 info@level-right.com www.level-right.com Level-Right underlayments are ideal for thin-topping applications over concrete. They provide a smooth, level new surface that dries fast and allows for placement of floor goods soon after application. Product advantages include the following: Use for new construction or renovation. Level entire floors or transition areas, featheredge to deep fill. Resurface old or damaged concrete floors. Water resistant. Cap cracked, lightweight concrete. Use above, on or below grade. Fill "duck ponds" in concrete floors. No troweling is required. Provide a temporary wear surface in as little as two to four hours after application. Experienced, authorized applicators are available worldwide. Exceeds standards set by leading floor goods manufacturers. Use in any continuous pumping machine. The concrete subfloor must be structurally sound and able to withstand live and dead loads with maximum deflection of L/360. Concrete moisture or vapor transmission must be eliminated prior to installation of products specified herein. Products specified herein are for interior use only. Maxxon underlayments are not a vapor barrier. The general contractor, architect, specifier, or building owner shall test below grade, on grade, or elevated slabs for MVER (ASTM F1869-09) or RH (ASTM F2170). If the MVER or RH of the concrete substrate exceeds the floor covering manufacturer's respective requirements for the finished flooring system, the concrete should be treated with a damp proof membrane (such as Maxxon DPM) before installing a Maxxon underlayment.
