ARDEX SD-F FEATHER FINISH
Self-Drying, Cement-Based Finishing Underlayment

ARDEX SD-F Feather Finish provides a smooth, permanent finish to a variety of substrates prior to the installation of today’s demanding floor coverings such as sheet vinyl and VCT. Feather Finish allows the installation of most types of floor covering in as little as 15 minutes over concrete, wood, ceramic and quarry tile – all without the need for priming or the use of a latex additive.

ARDEX SD-F Feather Finish mixes with water only to a creamy, smooth consistency for easy application. Engineered around a self-drying, Portland cement-based matrix, all of the mix water is chemically combined within the product itself. Using this unique technology, flooring installation problems associated with disbonding, crumbling, mildew and staining are eliminated, thus preserving the floor manufacturer’s full product warranty.

RANGE OF APPLICATION
Use ARDEX SD-F Feather Finish to smooth ridges, fill in cracks, gouges, and joints, and for skimcoating to a true featheredge over all types of interior concrete, masonry, wood, cementitious terrazzo, and quarry and ceramic tile.

ARDEX SD-F can also be used over properly prepared residues of cutback and other non-water soluble adhesives on certain applications. The residue on the substrate must be inert to the new adhesive being installed and the floor covering must not be susceptible to adhesive migration. If these two conditions are not met, install the ARDEX K-15 + E-25 Underlayment System using the recommendations of the Resilient Floor Covering Institute available from the ARDEX Technical Service Department.

To use ARDEX SD-F Feather Finish as an embossing filler, the use of ARDEX P-82 Ultra Prime is required.

ARDEX SD-P INSTANT PATCH
Self-Drying, Fast-Setting, Concrete Underlayment Patch

SELF-DRYING TECHNOLOGY: ARDEX SD-P InstantPatch is a Portland cement-based, self-drying, fast-setting, trowelable patch for smoothing and repairing concrete floors, ramps, 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 obtained readily. The finished surface hardens rapidly permitting the installation of most common floor coverings to proceed immediately. No additional drying time is required. 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. It was developed to reduce curing time on pressed-for-time jobs.
