The tile installation system provides a system for installing an architectural covering material to a substrate surface utilizing a plurality of release sheets where each release sheet has a top side surface and a bottom side surface. A plurality of discrete adhesive substrate portions are positioned on the top side surface of the release sheet, wherein the top side surface of the release sheet has a stronger bonding affinity with the plurality of adhesive substrate portions than the bottom side surface.

Mortarless tile installation system and method for installing tiles

The installation system and method for installing an architectural covering material to a substrate surface utilizes an adhesive mat having layers of adhesive and release layers arranged to allow the covering material to be initially positioned, and later repositioned to be permanently set. The adhesive mat includes a planar carrier member, one or more adhesive layers on at least one planar side of the planar carrier member, and at least one release layer of material removably covering the one or more adhesive layers. In one form, the adhesive mat includes a carrier sheet, first and second adhesive layers on opposing planar sides of the carrier sheet, and first and second release layers of material removably covering the two adhesive layers.

Methods and compositions involving the use of nitrogen-containing coordinated metal compounds for stabilizing chromium VI reducing metal cations. Exemplary uses include processes for making cement, and exemplary compositions include cement additives, concrete admixtures, as well as hydratable cement and cementitous compositions.

Coordinated metal compounds for reducing chromium

Exemplary compositions and methods for reducing hexavalent chromium in cementitious compositions involve the use of a liquid additive composition, comprising stannous chloride. Along with the stannous chloride may be used at least one co-additive comprising an antioxidant, oxygen scavenger, or mixture thereof, and/or at least one agent comprising a cement grinding aid, cement quality improver, or mixture thereof.

Cement composition having chromium reducer

A chromium VI reducing composition comprising particles of solid material selected from the group consisting of iron (II) sulfate and tin sulfate, the particles being substantially uniformly dispersed within a liquid carrier. Methods for modifying hydratable cementitious materials using the chromium reducing composition are also disclosed and provide advantages over dry powder or dissolved forms of sulfate compositions when used in cement manufacturing.
