1、基层要求：对于起砂地面进行清扫，无浮灰，保持干燥（可允许潮湿，但不得有明水）；   裂缝及缺损部位应用工程师灌浆系列及A3高强修补料修补后，统一用A5混凝土硬化剂   进行硬化处理。
1. Basic requirements: Clean sand-raising ground without floating ash, keep dry (moisture is allowed, but no clear water); apply engineer grouting series and A3 high-strength repair material to repair cracks and defects, and then use A5 concrete hardener to harden.
2、增硬处理：直接喷洒1#料，保证基层充分浸润吸收，随时补充被吸收的1#料，保持浸润状态，使   整个地面完全浸透；   随时将低洼处多余的1#料扫至已吸收处，应保证2小时内基层充分吸收1号料，且不应   有余料堆积；   起砂严重的地面可连续三天重复喷洒1#料一遍。
2. Hardening treatment: direct spraying of 1# material to ensure full infiltration and absorption of the grass-roots, replenishing absorbed 1# material at any time, keeping the infiltration state, so that the whole ground is completely soaked; sweeping the excess 1# material at any time to the absorbed place in the low-lying place, should ensure that the grass-roots absorb 1# material fully within 2 hours, and there should be no accumulation of excess material; and the ground with serious sand can be repeatedly sprayed 1 Once again.
3．耐磨处理：1#料施工至少48小时后采用2#料直接涂刷于经过增硬处理的地面，一遍即可，应均匀   饱满，不需养护，7天后可正常使用。
3. Wear-resistant treatment: 1. After construction for at least 48 hours, 2 # material is directly applied to the ground after hardening treatment, once, it should be even and full, without maintenance, and can be used normally after 7 days.
