Ardex SD-P Self-Drying, Fast Setting Concrete Underlayment​​​​​​

Use for interior floors only ARDEX SD-P® is a Portland cement-based, self-drying, fast setting, trowelable patch for smoothing and repairing concrete floors, ramps, and stairways, as well as non-porous substrates such as terrazzo, ceramic and quarry tile, prior to the installation of floor covering. When installed over standard absorbent concrete, no priming is required. Over non-porous substrates, the use of ARDEX P 82™ ULTRA PRIME ensures a permanent repair.

ARDEX SD-P sets quickly so that a smooth, steel-troweled surface can be readily obtained. Using advanced Portland cement chemistry with a self-drying matrix, ARDEX SD-P is ideal for patching and reaches a compressive strength of 4200 psi. The finished surface hardens rapidly, permitting the installation of most common floor coverings to proceed immediately – no additional drying time is  required. It was developed to reduce curing time on pressed-for-time jobs.

• Portland cement-based
• Provides a smooth surface prior to floor covering installation
• Mixes with water only – no primer required over concrete, no latex additive necessary
• Easy to mix and apply
