FeathercreteFEATHERCRETE® is an ultra fine textured, latex modified cement based patch. FEATHERCRETE® may be used to skim or fill most substrates without priming or the use of additives. FEATHERCRETE® is creamy and smooth spreading to provide a superior finish for the installation of most any floor covering, including sheet vinyl.

  • Easy mixing 2 to 1 ratio – just add water
  • Fast drying – install finished flooring in as little as 15 minutes
  • Compatible with most adhesives and flooring systems

  • 10 lb. (4.5 kg) double wall bag

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 0a 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 efflorescence and excess moisture. To check moisture test with a calcium chloride test (ASTM F1869-09) or the Relative humidity RH (insitu probe) test (ASTM F2170-09) to meet the requirements of the final finished floor. To correct moisture problems, including lack of proper under slab vapor barrier, see DEPENDABLE’s CUTDOWN II or VAPORSEAL HM.

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 WHITE LATEX LIQUID®. This will keep the moisture in FEATHERCRETE® or the adhesive from being drawn into the board, to 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 FEATHERCRETE®.

Metal Floors

Remove any rust or contaminants. Wash and allow to dry completely. Prime metal and mix FEATHERCRETE® 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 require abrading and/or priming the surface with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE. ACRYLIC EMBOSSING ADDITIVE must be added to the powdered product to in- crease 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. If adhesive interaction and migration is a concern, prime residue with DEPENDABLE ACRYLIC EMBOSSING ADDITIVE and allow to become nearly dry and tacky. Mix the Acrylic Embossing Additive full strength with the powder. Caution: Cutback adhesive may contain asbestos. Contact state or local authorities for proper removal and disposal procedures.

MIXING

After preparing the surface, use a clean mixing container. Add approximately 2 parts FEATHERCRETE® to 1 part cool clean water. Mix thoroughly to a lump-free trowelable consistency. To assure bonding over resilient (vinyl), adhesive residue, ceramic or metal floors or when a primer is required, mix ACRYLIC EMBOSSING ADDITIVE in place of water. Mixture will remain workable for 20 minutes. Do not mix more than you can place within 20 minutes. Do not attempt to extend pot life by later adding water. Avoid floor mixing. Always use clean containers and mixing implements, as leftover residue can accelerate set and/or reduce pot life of new mix. Mechanical mixing is recommended.

APPLICATION

Using a smooth flat trowel, force FEATHERCRETE® 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 1/2” 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 — 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. Material should remain workable for 15 minutes.

Metal Floors — Apply FEATHERCRETE® over the prepared surface. To assure no chemical reaction and a good bond, performing a test patch is recommended. If dissatisfied with bond, contact DEPENDABLE Technical Assistance

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 50ºF within 72 hours of installation
• Over presswood, particle board, masonite, chipboard, OSB, single layer stripwood floors, underlayment board not of APA underlayment (exterior) grade or similar dimensionally unstable materials susceptible to movement or swelling.
• Deeper than 1/2” in a single layer
• Over gypsum based patches or underlayment material without priming, due to chemical reaction.

WARNING

CAUSES SKIN IRRITATION. INJURIOUS TO EYES.

Contains standard portland cement and silica. Do not breathe dust. Dust can cause delayed lung injury (Silicosis). Use in a well ventilated area or wear a properly fitted NIOSH/MSHA approved respirator. Avoid eye contact. In case of eye contact, flush with water a minimum of 15 minutes. Consult a physician immediately. Avoid prolonged contact with skin. Wash thoroughly after handling.
