  • Mold and mildew resistant; self-drying, trowelable topping for fast-track finishing or resurfacing of interior concrete, terrazzo and ceramic, quarry and porcelain tile; Can be used to create a burnish-polished surface on indoor concrete; Can be used as pinhole filler for polished concrete and ARDEX Polished Concrete Systems (APCS) applications

  • For filling pop-outs and spalls up to 2” (5 cm) in diameter and 1/2” (12 mm) deep, use 3.5 parts powder to 1 part water by volume. Total L78thickness should not exceed 1/16”

  • ARDEX SD-M must be sealed with an appropriate film forming sealer or be burnish-polished in as little as 24 - 72 hours

  • Recommended Tools: ARDEX T-2 Ring Mixing Paddle, mixing bucket, margin trowel, steel trowel and a 1/2” heavy-duty drill (12 mm, min. 650 rpm)

  • INSTALLATION GUIDELINES: For one 10 lb (4.5 kg) bag of ARDEX SD-M, use 2 quarts (1.9 liters) of clean water. Pour the water in the mixing container first, and then add the ARDEX SD-M. For best results, mix with an ARDEX T-2 Ring Mixing Paddle and a 1/2” heavy-duty drill (12 mm, min 650 rpm). Mechanical mixing will produce a creamier, smoother consistency without the need for additional water. DO NOT OVERWATER! Additional water will weaken the compound and lower its strength. To mix smaller quantities by hand, use 2.5 parts powder to 1 part water by volume for the scratch and finish coat. For filling pop-outs and spalls up to 2” (5 cm) in diameter and 1/2” (12 mm) deep, use 3.5 parts powder to 1 part water by volume. Use a margin trowel and mix vigorously for 2 - 3 minutes. Just prior to application on the substrate, the mixture should be stirred again to ensure a creamy, smooth, lump-free consistency. The pot life of ARDEX SD-M is approximately 30 - 40 minutes at 70°F (21°C). If surface skinning occurs within this time, remix before using. Do not add more water. After mixing, apply a scratch coat of the mix to the substrate with the flat side of a steel trowel to obtain a solid mechanical bond. Apply sufficient pressure to fill all defects and to feather the product onto the subfloor surface. It is necessary to have a minimum of two coats of ARDEX SD-M with a total finished thickness of approximately 20 mils (500 microns, about the thickness of a standard business card). Use the least amount possible to attain the desired smoothness. The scratch coat, or base coat, should be applied to pre-smooth the surface, and the finish coat may be applied as soon as the trowel will not damage the base coat. A third application of ARDEX SD-M is optional depending on the desired finish and texture. This application is used primarily to achieve a very smooth, troweled finish. Total thickness should not exceed 1/16” (1.5 mm). ARDEX SD-M must be sealed with an appropriate film forming sealer or be burnish-polished in as little as 24 - 72 hours
