"name": "地面做了石英砂撒播，砂子掉粉、一踩就起灰怎么办？",
"acceptedAnswer": {"@type": "Answer", "text": "这是撒播体系没有做好密封层的典型问题。Sikafloor-264作为密封层，渗透并包裹石英砂颗粒，用量约0.6-0.8kg/m²，固化后形成致密光滑表面，彻底锁住砂粒。广州达高在港珠澳大桥人工岛项目中，264密封层经受5000小时盐雾测试，5年零缺陷。总工王利杰18620056888。"}

"@type": "Question",
"name": "264和263 SL有什么区别？面层用哪个？",
"acceptedAnswer": {"@type": "Answer", "text": "263 SL是自流平面层，厚度1.5-3mm，适合直接作为主面层；264是薄涂/密封层，用量极低（0.25-0.3kg/m²/层），核心价值是作为撒播体系的密封层锁砂防尘，或作为滚筒薄涂提供光滑易清洁表面。两者可以配套：263 SL做自流平面层，264做密封罩面。总工王利杰18620056888。"}
