(1) The silicone sealant
has stable quality and long-lasting effect, unlike the acrylic system. As a result, they are extremely cost-effective, especially when used in kitchens and bathrooms. Silicone sealants cannot be used as adhesives, which are generally more rigid.
Most silicone sealants are not painted. If you want to paint, choose hybrid sealant or acrylic sealant. It is recommended to apply a coating to the surface before applying the silicone sealant. Before sealing, the surface of the substrate is treated: the area of ? the substrate in contact with the sealant must be kept clean and dry, free from dust, dirt, rust, grease and other contaminants. Non-porous substrates must be cleaned with a clean, white, lint-free cloth and solvent. As soon as the residual solvent evaporates, wipe it off with a clean, dry cloth as soon as possible. Before sizing, cut the tube mouth, then attach the nozzle and cut the mouth to the desired size. The sealant can be applied in a punctiform or layered form and needs to be exposed to moisture from the air to cure. When applying the glue, make sure that the depth of the sealant is not greater than the width. If the gap between the two substrates is large, inserting the strip is required to improve the performance of the sealant. The sealant is smoothed with a suitable tool to make the surface more aesthetically pleasing and at the same time, the sealant is pressed into the joint surface to help eliminate cavitation or voids in the bond layer. Please pay attention to that you must use a straight line to apply the beauty gel, and you can't pause in the middle, because people who don't usually glue often, once they stop, then the glue interface will be unnatural. If you don't know the beauty glue is straight, it is necessary to stick the masking glue on both sides, and then peel off the masking glue after the surface of the cosmetic gel is dry. How to remove the cured sealant?
Use a sharp blade to scrape off the cured sealant.
The sealant is a fluid or extruded material that fills a closed joint and can rely on embedded drying, temperature changes, solvent evaporation, chemical cross-linking material stability and bonds, and progressively puts the solid glue, viscoelastic behavior Or elastic sealing material molding. Sealant method for outdoor use: First, seal the door frame or window frame gap, and choose a good quality sealant. If the hose is filled with sealant, use the cut nozzle part as the sealant sleeve and turn it upside down. The mouth acts as a seal. Then, apply the sealant to the gap. If the original mortar or putty appears to fall off, it should be shoveled off as soon as possible, and the gap should be cleaned first, then filled with sealant
. Then, when there is a small crack between the door frame or the window frame, but the putty is still intact, first use the tip of the knife to scrape the fallen dust, and then squeeze the silicone glue into the dry gap, a sticky, tough good sealant. Then, when the gap of the wall is deep, the sealant of the hose can be coated in a few guns to squeeze the sealant out of the depth, and the filling sealant should be slightly higher than the filling surface. Then you can smooth it with a wet finger. For shallower gaps, use a strip of frankincense adhesive, first remove the adhesive sealing tape, and then directly press the sealant into the sewing room. Then, when sealing other parts of the outdoor, when there is a hole in the sewage pipe on the outer wall, first put a new type of foam expansion filler into the pressure tank, and then spray the nozzle to the hole deep into the hole until the empty courtyard is filled with foam. After the foam has set, the surface is smoothed with a serrated kitchen knife. Finally, if the repaired Victorian hospital is wet, use a hot air gun to remove the paint and then seal it with a sealant. When using hot air, use a hot air to fill the surface slightly to prevent the glass from cracking or the paint is damaged.
