Abstract
An adhesive composition comprising a mixture of water based polymer in latex form and a material generally referred to as a thickening agent is disclosed for removably adhering a product to a substrate, for example a carpet with an attached backing to a flooring substrate. The adhesive may be applied as a layer to the carpet backing, dried and subsequently activated with water to adhere the carpet to the floor. After drying, the adhesive layer may be reactivated with water to permit the carpet to be removed from the floor. The adhesive layer when dried on the surface of a latex foam backed carpet provides a non-tacky surface which additionally increases the abrasion resistance of the latex foam backing thereby reducing damage to the backing during normal storage and handling.
