A composite floor covering comprising a rubbery backing strip or layer in intimate contact with the floor, ceramic tiles placed over the backing layer and flexible grouting between the tiles.

Resilient ceramic tile flooring

This invention relates to improved hydraulic cement mortar compositions which have the advantages of dry-set mortars and which have superior compressive strength as well as bond strength to both vitreous and non-vitreous tile.

Mortar compositions and method of making same

Novel aqueous non-hydraulic mortar compositions are disclosed comprising a film-forming, water-dispersible, room temperature cross-linkable polymer and a water-insoluble filler. Setting and grouting of ceramic tile by these compositions are also disclosed.

Mortar compositions

Portland cement mortar compositions containing sand and a cellulos ether are modified with certain clay, certain long-chain organic compounds, or mixtures thereof.

Sag-resistant dry-set mortar composition

A cementious composition is provided which comprises 25 to 100% Portland cement and from 0.001 to 0.25% of certain long-chain organic polymers having a Flocculation Index of less than 0.5. A dry-set grout composition may be prepared using the composition or a sag-resistant dry-set mortar compound may be prepared using the composition.

Cementious composition for use in preparing pointing compounds or mortar

Method of grouting using specific mortar composition

A new and improved grouting composition for impervious tile is provided which comprises not less than 50 per cent by weight of an inert filler aggregate which shall be graded with not more than 10 per cent passing a number 140 sieve and none retained on a number 6 sieve and an AFS Grain Fineness Number less than 100, but greater than 30; a water-resistant polymer emulsion having a solids content of at least 40 per cent and providing 7 to 15 per cent by weight of polymeric solids; volatile components from 5 to 15 per cent by weight and 10 to 35 per cent by weight of fine fillers which shall have an average particle size less than 140 mesh. In addition, a method for grouting impervious tiles employing such composition is also provided.
