沙雕被称为“速朽艺术”，它在一定的时间内自然消解，犹如一座古代城堡在悠远的岁月中不断风化，直到废墟，最后返归自然。所以从本体上讲，沙雕不存在刻意保存、收藏等问题，但是由于沙雕的商业因素，人们还是最大可能地延长每组沙雕的寿命，这也就不可避免地出现保存和修补的问题。 Sand sculpture is called "art" fails, it in a certain period of time, nature is like an ancient castle weathering, continuously in the long years until the debris, base shop nature at last. So tell from the ontology, sand sculpture does not exist the problem such as storage, collection, deliberately but due to the sand sculpture business factors, people still can prolong the life of each group of sand sculpture, it is inevitable to preserve and repair the problem. 每件作品完成后的喷胶是沙雕保存的关键，所以喷胶时应注意以下几点： Every piece of spray is the key to the preservation of the sand, so you should pay attention to the following points: 1、在喷胶前，应首先用喷雾器把整个沙堆全部喷湿，以便胶水迅速和均匀地渗入。 First, spray the whole sand with a sprayer in the first place, so that the glue will seep in quickly and evenly. 2、喷胶要均匀、仔细、充分，不可错过任何一个细节，以免一小点漏喷而迅速扩大风化面积，出现漏沙现象，直至损坏。 2, spray glue wants even, carefully and fully, don't miss any details, so as not to spray a little leakage and rapidly expanding weathering area, sand leakage phenomenon, until the damage. 3、把喷胶用的胶水以1：4左右的比例和水勾兑，并盛于专业大型喷雾器，即可喷胶。 Spray the glue with a ratio of about 1:4 to the water and fill it with a professional large sprayer. 4、如遇天气变化较多，可在天晴时适当多喷几次，以增加牢固度。 If the weather changes more, can spray several times in the weather, in order to increase the strength.
