Skimcrete-XLSKIMCRETE® XL is a fast drying, fast cover, latex modified, blended cement patch. This trowelable product is adhesive friendly, having the lowest alkalinity of blended cement patches to meet or exceed requirements of adhesive manufacturers. It is fast drying yet it has an extra long pot life, extending your opportunities, not delaying your finish. SKIMCRETE® XL is easy to work with on virtually any interior surface.

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. Floor must be free of ef orescence and excess moisture. To correct moisture problems, including lack of proper under slab vapor barrier, 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 of DEPENDABLE LATEX. 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.

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 AREA to nearly dry and become tacky before covering with SKIMCRETE® XL.

Metal Floors

Remove any rust or contaminants. 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. New wear layers being sold can be difficult to bond to. While some wear layers may be bonded to with just a thorough cleaning, others may re- quire abrading and/or priming the surface with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE™. ACRYLIC EMBOSSING ADDITIVE™ must be added to the powdered product to increase bonding characteristics. The installer is advised to always perform a test patch area over resilient goods to assure acceptable bond.

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.


Mix SKIMCRETE XL with cool clean water or DEPENDABLE latex additives for every 10 lbs use 1.5 quarts or 4 quarts for every 25 lbs. Use clean contain- ers 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 approximately 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 oor. Use felt, scrap vinyl or mixing bucket. Over vinyl oors or whenever a primer is necessary use ACRYLIC EMBOSSING ADDITIVE must be used in place of water.


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 & Metal Floors — When using SKIMCRETE® XL as an embossing leveler, mix approximately 2.5-3 parts SKIMCRETE® XL into 1 part ACRYLIC EMBOSSING ADDITIVE. Mix to a lump free trowelable mix. Apply using a at smooth steel trowel drawing material across the pattern to be filled at angles to the pattern to ensure an even and complete ll. Allow to dry completely, at least two (2) hours before covering.

LIMITATIONS – Do not use…

• Where hydrostatic pressure (water) exists or moisture emissions exceed level permitted for installing floor covering.

• Where surface or ambient temperature falls to or below 50°F within 72 hours of installation

• Over presswood, particle board, masonite, chipboard, OSB, underlayment board not of APA Underlayment (exterior) grade or similar dimensionally unstable materials susceptible to movement or swelling.

• Over gypsum based patches or underlayment material due to chemical reaction.

• Single layer stripwood floors.
