In the home decoration materials, there is no more grounding than sealant. Look at the toilet, pool table, window, glass, metal and other corner positions, all need the help of sealant.
Next let's take a look at the sealant construction. Simply speaking, when using the sealant, just use the extrusion gun to squeeze the gel into the gap to be filled, and it can be solidified in a day under normal room temperature, forming a watertight sealing effect.
Sealant construction process
Preparation of construction materials and tools
Manual or pneumatic glue gun; scraper, masking paper, wallpaper knife, cleaning blade; gloves, wipes, etc.
Grass-roots treatment
Gap cleaning, paste masking paper
The gap of base material shall be cleaned; the old and residual glue shall be removed, and the surrounding of the gap shall be clean and dry without oil, water and dust. Paste masking paper on both sides of the gluing part.
Glue gun installed
Cutting rubber head, cutting rubber pipe and installing rubber pipe
The nozzle diameter shall be less than the gap width, so that the nozzle is one-half deep into the interface. Make the gap rubber full and full without material shortage.
Glue construction
Single direction continuous and uniform glue injection to prevent cavity or blister.
Pressure joint treatment
Screeding and caulking. After the glue injection, press the glue in one direction with a scraper to remove bubbles, repair the glue surface into a flat or curved surface, and remove the masking paper after finishing the decoration.
Material maintenance
The sealant shall be cleaned and maintained after construction, and it can be solidified in one day generally.
Key points for construction
(1) Before use, the sealant shall be kept within the warranty period. After the rubber nozzle is cut, please use it within half an hour. If the glue at the outlet of the glue nozzle becomes hard, it can be used after cleaning the solidified glue. (2) The sealant before curing shall avoid contact with eyes and skin. In case of contact with skin, first scrub with soap water or alcohol, then rinse with water. In case of contact with eyes, wash with plenty of water first, and seek medical treatment immediately if necessary. (3) The construction environment temperature is 5 ℃ ~ 40 ℃, and the relative humidity is 40% ~ 80%. If the air is too dry or the temperature is low, the curing speed will be slowed down. The temperature of substrate and ambient air shall not be lower than 5 ℃,
(4) The surface of the constructed silicone base material should not be applied with glue. If the glue is to be applied, it is necessary to thoroughly clean or cut and polish the polluted base layer with alcohol and other solvents. (5) Silicone sealant will release a small amount of odor during curing, and the working environment should be well ventilated.
Due to the different sealing requirements of different base materials, sealant is also extremely exquisite in material, process and performance. According to the sealing requirements and use scenarios of different base materials, different sealants should be purchased. Before purchase, you must see the instructions clearly~
