摘要： A marble and brick surface restoring composition comprising a mixture of trisodium phosphate, talc and sugar, which is prepared by dissolving the trisodium phosphate in boiling water to which is added the talc and sugar to form a paste. The paste is applied to the surface to be restored by a suitable applicator such as a brush or trowel; the coated surface is covered with a thin plastic sheet and the coating is allowed to set. The composition is removed from the restored surface by a squeegee and the surface is rinsed with water or steam.When restoring detailed surfaces, such as headstones, cheese cloth is first wrapped around the surface and the paste is sprayed thereon to form a poultice which is covered with a thin plastic sheet. After setting, the poultice is peeled from the surface and the restored surface is rinsed with water or steam.
摘要翻译：一种大理石和砖表面恢复组合物，其包含磷酸三钠，滑石和糖的混合物，其通过将磷酸三钠溶解在沸水中而添加滑石和糖形成糊料而制备。将糊剂通过合适的施用器如刷子或抹子施加到待恢复的表面上; 涂覆的表面被薄的塑料片覆盖，并且允许涂层固化。通过刮板将组合物从恢复的表面上除去，并用水或蒸汽冲洗表面。当恢复诸如墓石的详细表面时，首先将乳酪布缠绕在表面上，并且将糊剂喷在其上以形成用薄塑料片覆盖的泥敷剂。放置后，将泥敷剂从表面剥离，并用水或蒸汽冲洗恢复的表面。
