Construction technology: Before construction, carefully clean up the oil stains, loose objects and other pollutants on the surface and cracks of building bricks; And ensure that the tile surface and tile joints are dry and waterless, so as to avoid colloid whitening or whitening after construction; During construction, a glue gun must be used, the cap of the American porcelain bottle must be unscrewed and put into the glue gun, and at the same time, glue must be applied until AB component is discharged; Install the matching glue nozzle, press the glue gun to hit the glue 40cm in front of the glue outlet on the waste paper, and observe the color of the glue until there is no color difference and the glue outlet does not spread. At this time, start to glue evenly for the gap; After gluing, use a professional seam-pressing steel ball (to be purchased separately) to forcibly pull from one end to the other along the brick seam, and keep the stress uniform; In summer, at room temperature for about 8 hours, use a knife or shovel to clean the residual substances on the surface of ceramic tiles that are not completely solidified; When the temperature is low in winter, it is necessary to extend the cleaning time; If it is necessary to keep the sealant on the same level as the surface of the tile after curing, you can stick masking paper on both sides of the tile, stick it and smooth it along the gap with a scraper, let it stand for 5- 10 minutes, and tear off the masking paper.
