When using the seam an agent construction, why bubbles and discoloration occurs

In the use of beautiful seam an agent to do beautiful seam construction process will encounter the following problems: the bubbles and becomes angry, don't worry about these problems. Let us first to get to know the reason for these problems. The construction of why bubble? 1, ceramic tile gap with ash, not clean. When the seam construction, must use the vacuum cleaner to clean ceramic tile aperture, prevent dust pollution, can appear otherwise beautify the seam surface uneven situation. 2, ceramic tile base processing is bad, gap within the water vapor. In front of the sewing construction, therefore, must keep dry and ceramic tile aperture, otherwise there will be a great sewing fade. At the same time, with the evaporation of water vapor, will produce bubbles. 3, ceramic tile narrow clearance, construction speed is fast. Beautiful seam construction suspended or sizing too fast, beautiful seam an agent did not enter inside crack, and in the surface layer, causes the bottom gas. When the joint is pressure in the back, the inside of the gas can't discharge, bubbles which leads to the joint. 4, the thickness of the seam an agent is too thin. In the construction process of joint, adhesive is too thin, can't make the air inside the crack is compact, easy in the construction of joint produce bubbles. 5, beauty of seam an agent was of poor quality. Due to the poor quality of seam an agent production process, in the process of production of colloidal inclusions of gas, cause air bubbles appeared in the process of construction. The cause of the seam an agent fade? 1, before the construction or construction process, ceramic tile cracks should not be too much water or steam. Because when the seam an agent contact with water, it will cause a chemical reaction, thus affect the color of the seam. 2, if ceramic tile gap or continuous rain, damp, seam an agent that can cause color change.
