Abstract
A peelable protective composite for flooring is made of an open mesh fabric embedded in a polymeric film having a tensile strength of at least 5 megapascals, an elongation of more than 1,000 percent, and adhesive strength of no more than about one megapascal. The protective composite can also be used to enhance curing of freshly poured concrete.
Claims16
A method for applying an adherent but peelable protective composite on a flooring surface which comprises the steps of
- placing a liquid permeable, open mesh fabric contiguous with the flooring surface;
- thereafter applying to said web a water-based, film-forming liquid in an amount sufficient to pass through the web, wet the flooring surface, surround the web, and form a liquid layer in contact with the flooring surface;
- and
- solidifying the liquid layer by drying to form a film;
- wherein the film-forming liquid is a polymerizable resin dispersion in water having a viscosity in the range of about 16,000 cP to about 20,000 cP at 20 degrees C. and a solids content of at least 30 percent by weight.
A peelable protective composite comprising an open mesh fabric embedded in a polymeric film having a thickness of at least 100 microns and a tensile strength of at least 5 megapascals.
A method for enhanced curing of a concrete slab having a polished surface which comprises the steps of
- placing a liquid permeable, open mesh fabric on the polished surface;
- thereafter applying to said web a water-based, film-forming liquid in an amount sufficient to pass through the web, wet the polished surface, surround the web, and form a liquid layer in contact with the polished surface;
- and
- solidifying the liquid layer by drying to form a film;
- wherein the film-forming liquid is a polymerizable resin dispersion in water having a viscosity in the range of about 16,000 cP to about 20,000 cP at 20 degrees C. and a solids content of at least 30 percent by weight.
