It is not difficult to apply sealant like a professional. With the help of professional guidance, you can do many things yourself. Meticulous preparation, high-quality materials and the use of the right tools will help you.
1.Before applying sealant, clean the joint with an acetone-based cleaner to remove all grease and other dirt. Pour the cleaner on a clean cloth and thoroughly clean the joint and the surface. To protect your skin, it is recommended to wear gloves when working. If the joint is deep, you can insert a foam stick, which will make the sealant used in the subsequent process more secure and reduce the possibility of cracks.
2.In addition, the sealant should only adhere to the two sides of the joint surface, so that all movements can be absorbed as flexibly and effectively as possible, thus preventing damage. Use a cutting tool or a sharp knife to cut the sealant barrel, then screw in the included nozzle, cut off the tip of the nozzle and cut it into a bevel. Use the right tools to avoid injuries.
3.The nozzle opening should be the same size as the width of the joint. Place the sealant barrel in the caulking gun and fix it with a tie rod. The cartridge should be secure, squeeze the sealant out of the cartridge to the tip of the nozzle, hold the gun firmly, inject the sealant into the joint at a 45-degree angle, and move along the joint at a constant speed. The gun should ensure that the amount of sealant injected into the joint is just right, not too much and not too little.
4.Use a wooden or plastic scraper to scrape off all excess sealant at a 45-degree angle, be careful not to touch your body when scraping, and catch the excess sealant with your hands to avoid unnecessary mess. Please remove the residual sealant on the scraper. If there is still a small amount of residual sealant, use a small scraper to scrape it off. Then apply the diluted rest agent to your fingers and wipe along the joint. Finally, don't forget to wash your hands and apply hand cream.
If you have just completed these operations very carefully, you should now see a triangular joint. Depending on the specific temperature, it will take at least 24 hours for the joint to reach its maximum load-bearing capacity. First, the surface of the sealant begins to form a crust, and the sealant undergoes a cross-linking reaction under the action of moisture in the atmosphere and begins to cure.
