UZIN NC 888 is a fast drying highly versatile smoothing compound for repair, filling and patching. It can be used on wide range of substrates to repair subfloor imperfections prior to installation of most flooring products. UZIN NC 888 has very fine aggregates enabling it to be applied by trowel from a true feather edge up to 1” (25 mm) depth in a single application. It has superior bonding properties to plywood, concrete, ceramic tile, terrazzo, and old non-water soluble adhesive residues including properly prepared cutback adhesive residues without the use of a primer*. It is quick drying cement which allows for most floor coverings to be installed within 15 minutes on absorbent substrates. UZIN NC 888 is an ideal material for covering / smoothing minor imperfections, holes, trowel marks, skim coating and ramping. For interior use only.
The subfloor must be structurally sound, solid, dry, free from active cracks, clean and free of all contaminants such as grease, oil, paint, wax, curing and sealing compounds that would impair adhesion. Test the substrate in accordance with applicable standards relative to moisture content. Any weakly bonded or soft surface material such as loose adhesive residues, leveling compounds, floor coverings or coatings must be removed by shot blasting, abrading, grinding or wet scraping. Thoroughly vacuum off all loose material or dust. Caution: Do not sand or grind adhesive residue, as harmful dust may result. Inhalation of asbestos dust may cause asbestosis or other serious bodily harm. Refer to the Resilient Floor Covering Institute’s publication “Recommended Work Practices for Removal of Resilient Floor Coverings” for instructions. UZIN NC 888 is suitable for use over a wide range of subfloors, generally without the use of a primer.
