PREPARATION AND APPLICATION
|
|
SURFACE PREPARATION - All supporting surfaces shall be structurally sound, solid, free of movement and well bonded. Ensure underlying surface is free of excess moisture and clean of any contaminants such as dirt, wax, oil, paint, curing compounds, sealers, solvent, oil products or any gypsum materials or foreign matter that may interfere with a proper bond. When a proper bond is questionable, perform a test patch in an inconspicuous area. DO NOT PROCEED if dissatisfied with bond and contact DEPENDABLE’s Technical Services.
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 by performing a mat test with a rubber-backed mat or plastic sheet taped to the surface. To correct moisture problems, see DEPENDABLE’s moisture protection products.
Wood Floors
Ensure wood floors are free of movement and excessive moisture. Fasten any loose boards. Stripwood floors should be covered with underlayment grade quality 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 other “raw” spots with an appropriate brush coat or DEPENDABLE WHITE LATEX LIQUID. This will keep the moisture in SKIMCRETE XL 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 ACRYLIC EMBOSSING ADDITIVE. Allow to nearly dry and become tacky.
Vinyl Floors
Existing resilient floors shall be single layer, fully adhered and well bonded. Thoroughly clean all foreign matter such as dirt, grease, oil, wax or any other contaminates which may inhibit bond. While floor is wet, use a cleaning pad and remove any remaining wax or dirt, while scuffing the surface. Rinse thoroughly with clean water and allow to dry.
Adhesive Residue
Using mechanical means, remove loose, brittle or thick/heavy accumulations to a 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 SKIMCRETE XL.

|
MIXING
|
|
Add about 3 parts SKIMCRETE XL into 1 part cool, clean water. 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 15-20 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. Over vinyl floors or when ACRYLIC EMBOSSING ADDITIVE is used as a primer, it must be used as the additive in place of water.
|
|
APPLICATION
|
|
Using a smooth flat trowel, force SKIMCRETE XL into joints, cracks, holes and deeper fills bearing down on the trowel. Smooth the surface to a thin covering over the prepared substrate. Build any thicker fills or transitions to 5/8" thick. Deeper fills may be achieved with multiple lifts. Always allow prior lift to dry completely. When dry, sand or
scrape smooth for a perfect finish.
Vinyl Floors – When using SKIMCRETE XL as an embossing leveler, mix approximately 3 parts SKIMCRETE XL into 1 part ACRYLIC EMBOSSING ADDITIVE. Mix to a lump free trowelable mix. Apply using a flat smooth steel trowel drawing material across the pattern to be filled at angles to the pattern to ensure an even and complete
fill. Allow to dry completely, at least two (2) hours before covering.
Metal Floors – To assure no chemical reaction and a good bond, performing a test patch is recommended.
