Whether for industry or for domestic dwellings, paint coatings provide both protection and decoration to all types of surfaces. In domestic dwellings, floors are usually covered with carpet, this is hardly practical in industry where floors are liable to be subject to splash and spillage of process liquids, moving machinery trolleys, trucks and fork lifts which can and do deposit dirt, dust, soil and grease to be ingrained into the surface. With acidic solutions, chemical attack will expose aggregates. In areas requiring high standards of hygiene, cleanliness and appearance, a suitable paint coating enables the floor to be maintained in a clean condition. In the sugar industry, dry sugar has negligible effect on concrete but juices at various stages of concentration, and molasses are sometimes spilled. These are broken down to lactic and acetic acids which attack concrete.
