Description: URAS/SIGA is a full surface textile re-enforced double sided self stick roll flooring adhesive. It is VOC free, free of odors, carcinogens, out-gassing and is totally safe for people. The adhesive is acrylic based, plasticizer resistant, contains no formaldehydes and has unrestricted waste disposal. URAS/SIGA has a lower adhesive strength to the old flooring and a high strength adhesion to the new flooring. Installations (i.e. carpet tile over access floors, trenches, or old carpet) are releasable (some restrictions may apply).

Applications: Sub-floors - URAS/SIGA may be installed only over dry (<3.0 lb/1000 sft.) structurally sound firm dust and oil-free surfaces, such as concrete, VAT, vinyl composition tile, homogeneous vinyl sheet or tile, poured epoxy, ceramic, stone or terrazzo. It may be used over steel or HPL covered access floors. It may be used over wood and parquet, plywood and laminates only if these sub-floors are free of acrylic finishes and are not directly installed over on-grade or below-grade concrete without an air space between the concrete and the wood products due to possible moisture conditions. Not recommended for use over gypsum patches. Not suitable for outdoor installations. URAS/SIGA may be used to adhere carpet with jute, Action Bac®, SBR foam back, Unibond and carpet tile with glass fiber reinforced vinyl backings or bituminous backings. It is also used to install solid vinyl sheet or tile.

Unsuitable New Flooring: Dimensionally non-stable flooring products, rubber sheet or tile, vinyl composition tile (dusty back), wood or laminate floors, cork, cocos are not suitable. Certain recycled rubber flooring has limited suitability. Recycled EPDM based rubber is not suitable.

Advantages of Installation with URAS/SIGA Dry Adhesive: Save the dust, debris, expense of disposal of old flooring and re-prepping of old sub-floors necessitated by tear out. Dry adhesive has no open time. It can be laid directly over old floors. Vinyl may be heat welded immediately. Installations may be subjected to rolling loads and heavy traffic without waiting.

 

General Installation: Roll out URAS/SIGA perpendicular to new flooring. Overlap and double cut seams. Unroll new vinyl, seam seal as per manufacturer's specifications. Roll and put into service.
