Bostik Fast Patch 102™ 25lbs is a fast-setting latex-fortified Portland cement patch for interior use. 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 Fast Patch 102 is extremely flexible and resilient for use 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 Hydroment 425 Multi-purpose Acrylic Latex Admixture™ instead of water, not only is the performance and flexibility improved, but Fast Patch 102 can also be used as an emboss leveler.

Surface preparations


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 45°F.


Mixing Instructions


Add 25 lbs of Fast Patch 102 to 3 3⁄4 quarts of clean, cool, potable water or Hydroment 425 Multi-Purpose Acrylic Latex Admixture. DO NOT OVER WATER. Do not mix more material than can be used in 10 to 15 minutes. Thematerial may be re-mixed; 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).
