Hard Floor Care – Maintenance of Natural Stone Floors

Hard Floor Care – Maintenance of Natural Stone Floors Immediately after laying, it is advisable to remove any grout or cement bedding material which may have appeared on the surface of the stone. This can best be carried out by hand using a damp cloth. If, however, the grout or cement has dried hard, it can be removed from those stones that resist acid (for example granite, sandstone, quartzite and slate) with a solution of hydrochloric acid diluted in the proportion of 1 part acid to 4 parts water. A small area should be treated at a time, removing the cement with mops as soon as loosened. It is important that this operation be carried out as quickly as possible because acid will attack the cement between the stone slabs. After cleaning, the floor should be rinsed very thoroughly, several times, to ensure that no acid remains. It is advisable to use an old mop and have the acid solution in a plastic rather than in a metal bucket. Operators should wear rubber gloves and goggles (if required). The maintenance of a stone floor mostly depends on two main factors, namely the type of stone and the porous cement or grout between the stones. While stone itself is relatively easy to maintain, it must re recognized that porous cement or grout can be affected by acids and many other chemicals. Acids and strong alkaline detergents should, therefore, be avoided. Harsh abrasive materials can damage the cement or grout and may even scratch soft stone. If an abrasive is required for any purpose, a test should first be carried out on a small area in an out-of-the-way place to ensure that it is suitable for the task. Consider carefully the proper janitorial equipment to be used on stone floors. Some stones are stained by oil and grease, resulting in a dark unsightly discoloration. Oily type sweeping compounds and oily dust mop dressings should, therefore, be avoided. If stone has become discolored with oil, it can be removed with detergent crystals, as described in the article dealing with concrete. A poultice of whiting and white spirit can also be used, if required. Steel wool should not be used on stone floors because of the possibility of fragments becoming detached and subsequently rusting. Synthetic floor machine pads are preferred. Sealing Natural Stone Floors: In most situations, it should not be necessary to seal natural stone floors. However, it is recognized that in some circumstances a seal may be desirable to protect the cement or grout and occasionally to add gloss to the surface. If the floor is subject to heavy traffic, it may require resurfacing rather often. On these occasions, a water-based, acrylic type of seal that is water-white in color and non-yellowing should be selected. On occasions a water emulsion floor finish or wax may be used to either improve the appearance or to assist in providing a non-slip surface. Daily Cleaning Of Natural Stone Floors: Natural stone floors should normally be dry swept to remove loose dust and dirt. This procedure can be followed by mopping with a solution of neutral detergent in water. The floor should then be rinsed and allowed to dry following the use of regular neutral detergent. The cleaning equipment is the same that is used on resilient tile floors.   Search For Cleaning Supplies And Cleaning Products On Our Online Store
