求翻译：3、使用时将的防水剂原液用水稀释以原液∶水＝1∶18~20的比例，稀释成3％或是更低的浓度。如需要使用高于3％的浓度必须先进行实验验证，使用浓度高会导致在防水表面形成白色残留物。涂刷后使被处理表面自然晾干，表面未干前再涂刷第二遍。如使用在石材、瓷砖表面防护处理，施工后5～10min用软布抹去多余的液体，不沾水养护至少24h。是什么意思？

3, the waterproofing agent used to dilute the liquid water to liquid: water ratio = 1:18 to 20, diluted to 3% or less concentration. If you need to use more than 3% of the concentration must be carried out experimental verification, the use of high concentrations of lead in surface water white resid

3, when used in the original liquid should be diluted with water-proofing agent to original liquid: water = 1:18 ~ 20 dilution ratio of 60% to 3% or less concentration. Where there is a need to use more than 3 per cent of the concentration must first make an experimental verification will result in

3rd, when use the water-repellent original fluid water used will dilute by the original fluid : The water =1∶18~20 proportion, dilutes 3% perhaps a lower density.If needs to use is higher than 3% density to have to carry on the experiment to confirm first, the use density high can cause in the water

3, use waterproof agent when liquid water to liquid: water ratio of =1:18~20, 3% or lower concentration of diluted. Need concentration required to conduct experiments used over 3% using high concentration could result in waterproof surface white residue. Brushing after is processed naturally on the
