  • - Featheredge finish

DESCRIPTION

Bostik Webcrete 95 is a fast-setting, polymer-modified, Portland cement patch for interior use on floors and walls. This product may be used to skim coat or featheredge finish up to 1/2" deep in one application. Floor covering can be installed after just one hour from application. Bostik Webcrete 95 is used to patch and smooth floors prior to the installation of engineered hardwood, solid wood, laminate, ceramic tile, carpet, and resilient flooring. It can be used over properly prepared concrete; cementitious backer board; structurally sound exterior grade plywood (interior/dry use only); existing, well bonded vinyl/VCT or ceramic tile; and cutback adhesive residue (dry only). When mixed with Bostik 425TM Multi-purpose Acrylic Latex Admixture instead of water, not only is the performance and flexibility improved, but Bostik Webcrete 95 can also be used as an embossing leveler.

DIRECTIONS FOR USE

Read and understand technical and safety data sheets completely before beginning installation. Follow industry standards and recommendations for subfloor moisture content, design, layout and application. Refer to www.bostik-us.com for the most recent product information and safety data sheet prior to installation.

SURFACE PREPARATION

Surfaces must be structurally sound, clean and free of dust, dirt, paint, soap film, adhesive residue, grease, curing compounds and other foreign material that could inhibit bonding. For best results, material and surface should be at or above 45F (7C). Note: It is the user's responsibility to determine the condition and suitability of all surfaces before application.

MIXING

Add 25 lb. of Bostik Webcrete 95 to 3 quarts of clean, cool, potable water or Bostik 425TM Multi-Purpose Acrylic Latex Admixture. DO NOT OVERWATER. Do not mix more material than can be used in 10 to 15 minutes. The material may be remixed; do not re-temper by adding liquid. The pot life of the material is dramatically affected by jobsite conditions, the powder/liquid mix ratio, and temperature of the jobsite and materials (i.e. cold materials, jobsite, and mixing water will extend the pot life).

APPLICATION

With the trowel held at a 45 angle, work patch into surface filling all broken areas, depressions and cracks in the substrate.

Application over plywood: Please refer to the proper flooring industry and APA standards for plywood subfloor installation and preparation. Clean and rough-sand the plywood. Due to the limitations of plywood as a substrate, it is not intended for use in exterior, wet interior, or applications subject to heavy/commercial traffic.

Application over existing cutback adhesive residue: Cutback adhesive must be dry. Thoroughly scrape the cutback adhesive residue from the floor to remove any loose pieces of material prior to installing Bostik Webcrete 95.

Application as an embossing leveler or installation over existing VCT/vinyl: Bostik Webcrete 95 must be mixed with Bostik 425TM Multi-Purpose Acrylic-Latex Admixture when used as an embossing leveler. Vinyl/VCT must be clean and well bonded to the substrate. Remove any loose pieces of vinyl/VCT flooring. Roughen new or smooth surfaces, or flooring with urethane wear layers.

Do not apply over cushion-backed or perimeter bonded sheet vinyl. The installation must be thoroughly rinsed and dried. Use the flat side of a trowel held at a 45 angle to spread a thin layer of Bostik Webcrete 95 over the embossed floor covering. An embossing leveler need only be thick enough to fill in the depressions of the floor covering. Make sure coverage is smooth and uniform; avoid over-troweling. A second application may be required on deeply embossed floors. Do not apply over cushion backed or perimeter bonded sheet vinyl.

CAUTION: Some flooring and cutback adhesive may contain asbestos. Follow all Federal, state and local guidelines for proper removal. Refer to the Resilient Floor Covering Institute's "Recommended Work Practices for the Removal of Resilient Floor Coverings."

Application over existing ceramic tile: Ensure that the ceramic tile is clean and well bonded to the substrate. Mechanical abrasion with a Carborundum disk is required, followed by a clean water wash. The installation must be thoroughly rinsed and dry prior to applying Bostik Webcrete 95.

CLEAN UP

Wash tools immediately with water.

CURING

Do not allow traffic over floor for 1 hour.

LIMITATIONS

  • The use of solvent-based flooring adhesive over Bostik Webcrete 95 is not recommended.
  • For areas larger than 4 ft2 with a consistent 1/2" depression, the use of a Bostik Self-Leveling Underlayment is recommended.
  • This product is not designed as a wear surface; an appropriate floor covering must be installed before it is open to normal traffic.
  • Cutback adhesive must be fully removed prior to installing solid wood flooring.
  • When installing hardwood flooring, a 3 to 4 hour drying time of Bostik Webcrete 95 may be required.
