Hydraulic cement coatings and method of forming and applying the coatings

Abstract

Dry mixes for hydraulic cement coatings for masonry, plastic insulating and dry wall substrates includes selective mineral aggregates, water reducer, and fine ceramic fibers, in various proportions for the different substrates. The ceramic fibers expand in the water of the applied coating and are trapped within the small recesses in the substrates. The ceramic fibers include different micron sizes in the range of 20 to 40 for masonry about 120 microns for plastic insulating substrates particularly foam plastic substrates. The fibers expand in the wet coating applied to substrates and remain in that state to bond to the substrates.
