Abstract
A seam cleaning paste, cream or liquid is disclosed, which comprises a hydrocarbon solvent and a finely divided inorganic powder. Treatment of the area near the seams of various types of floor coverings, especially highly stain resistant and soil resistant floor coverings, does not significantly change the appearance of the floor nor its resistance to soiling or staining. Yet it results in much improved adhesion of certain seam coaters subsequently applied to bridge the seam and prevent dirt from lodging therein. These creams do not exaggerate bubble formation in subsequently applied seam coaters and in fact, preferred embodiments help prevent such bubbles from forming.
