PREPARATION AND APPLICATION
|
|
| Surface Preparation - All supporting surfaces shall be structurally sound, solid, free of movement and well bonded. Make sure underlying surface is free of moisture and clean of any contaminants such as dirt, solvent, wax, paint, sealers, adhesive, chemical residue, oil products, or any other foreign matter that interferes with bond. In any application where adhesion is in doubt, perform a test patch in an inconspicuous area. Do not proceed if dissatisfied with bond and contact Technical Assistance. |
| Concrete Floors Remove all foreign matter by mechanical means. Floors must be free of efflorescence and excess moisture. To check moisture, test with a calcium chloride test kit (ASTM F1869), or relative humidity (insitu probe) test (ASTM F2170). To correct moisture problems, see DEPENDABLE’s moisture protection products. |
| Wood Floors Ensure wood floors are free of excessive moisture and well supported. Fasten any loose boards. Stripwood floors should be covered with underlayment board. |
| Underlayment Board Joints To avoid peaking, do not butt sheets tightly. Leave a space the thickness of a matchbook cover (approx. 1/32") between sheets. The installer may wish to seal the joints, hammer-indents and any other “raw” spots with an appropriate “brush coat” or DEPENDABLE WHITE LATEX LIQUID. This will keep the moisture in SKIMCOAT and/or the adhesive from being drawn into the board, which may cause swelling and/or delamination. |
| Metal Floors Remove any rust or contaminates. Wash and allow to dry completely. Prime with DEPENDABLE LATEX LIQUID. Allow to nearly dry and become tacky. |
| Vinyl Floors SKIMCOAT will work well over one layer of well adhered, full spread non-cushioned vinyl floor without a urethane wear layer. (For vinyl of cushioned construction or with urethane wear layer, DEPENDABLE SKIMCRETE XL® with ACRYLIC EMBOSSING ADDITIVE makes an excellent embossing system). Thoroughly clean the surface of any foreign materials and wax buildup. WHILE THE FLOOR IS WET, lightly rough the surface with a cleaning pad to remove any remaining wax or dirt and scuff the surface. Rinse and dry surface. |
| Adhesive Residue Using mechanical means, remove loose, brittle or thick/heavy accumulations to a minimal well-bonded residue. Sweep or vacuum area. Prime residue with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE and allow to become nearly dry and tacky. Caution: Cutback adhesive may contain asbestos. Contact state or local authorities for proper removal and disposal procedures. |
Existing Ceramic Tile, Quarry Tile, etc. (Not Vinyl - VCT & VAT) must be well bonded. The surface must be clean and free of waxes and contaminants that might inhibit bonding. For best bond, prime with Acrylic Embossing Additive. Once primed, allow AEA to nearly dry and become tacky before covering with SKIMCOAT.

Mixing
|
|
| Add about 2 1/2 parts SKIMCOAT into 1 part cool, clean liquid. Use clean containers and mixing implements, as leftover residue can accelerate set and/or reduce pot life of new mix. Mix thoroughly to a lump-free trowelable consistency. Mixture will remain workable for 10-15 minutes. Mix only what can be used in that time. Do not attempt to extend pot life by later adding water. Do not mix directly on floor. Use felt, scrap vinyl or mixing bucket. When using as embossing leveler or otherwise with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE, mix 2 parts powder into 1 part liquid. ACRYLIC EMBOSSING ADDITIVE will extend working and drying time of SKIMCOAT. |
NOTE: DEPENDABLE WHITE LATEX LIQUID and ACRYLIC EMBOSSING ADDITIVE, used at full strength, contain mildewcides and other protections specifically formulated for SKIMCOAT and are highly recommended for use in most applications. Use of water or latex not containing the protective qualities of DEPENDABLE WHITE LATEX LIQUID or ACRYLIC EMBOSSING ADDITIVE as an admixture for SKIMCOAT will void warranties, whether express or implied, for stain and mildew resistance, moisture resistance, adhesion and under vinyl sheet goods.

|
Application
|
|
| Using a notchless trowel, force SKIMCOAT into joints, cracks, voids and deeper fills bearing down on the trowel, then smooth a thin covering over the prepared substrate and build any thicker fills or transitions to over 1 inch thick. Allow the SKIMCOAT to dry thoroughly before going over the surface with a second application if needed. When dry, scrape or sand smooth for a perfect finish. |
| Vinyl Floors - Apply SKIMCOAT mixed with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE, using a flat steel trowel. Draw the SKIMCOAT material across the pattern to be filled at angles to the pattern to ensure an even and complete fill. |
| Metal Floors - For best bond and flexibility, apply SKIMCOAT mixed with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE over a surface primed with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE. Good bond and flexural strength can also be achieved by mixing SKIMCOAT with DEPENDABLE WHITE LATEX LIQUID and applying over a surface primed with DEPENDABLE WHITE LATEX LIQUID. |
Setting Marble, Sills, Grouting Tile - Use a mortar mix (about 3 parts SKIMCOAT to 1 part liquid). When applying SKIMCOAT as a grout, use rubber float trowel. Wipe all excess clean before it sets.
