G654 sesame black stone is widely used as a decorative stone, mainly used for paving interior walls and floors. Sesame black stone is prone to spit yellowing after a long time after paving due to its high iron content, forming yellow spots on the surface. So, how to prevent G654 sesame black stone macula? Next, let's take a look with the editor of FABULOUS Group.
1. Use inferior curing agents as little as possible;
2, try to avoid using high-alkali cement or inferior adhesives for installation and construction;
3. Pay attention to maintenance at ordinary times, and clean up the dirty juice in time.
4. Try to use marble with fewer cracks and low clay content;
5. Try to use stone with lower sensitive elements;
6. It is recommended that all stones be protected on six sides before installation; before installation, protection should be carried out to prevent moisture from entering the slate, so as to avoid oxidation reaction of iron-containing minerals with moisture and oxygen in the air to cause rust yellow. Before installing the stone, use an oily protective agent such as SINO-1250; after 24 hours, apply the stone sealant SINO-1600 evenly on the bottom surface and 4 sides (except the surface) of the stone; sprinkle it when the bottom surface sealant is not completely dry A layer of fine sand to enhance the bonding force between cement and stone; finally dry, keep the stone from contact with water molecules within 24 hours. The bottom sealant forms a tough and transparent protective film on the back of the stone, which effectively protects the occurrence of stone diseases such as white bloom, yellow spitting, rust spots, and macula.
7. Try to avoid using straw rope, cardboard, wood and other materials to protect, pack or transport stone.
8. When using marble with more cracks and high clay content or granite with iron content and high sensitive element content, it is recommended to use high-quality protective agents for six-sided protection before installation;
