Step 1
Remove old silicone caulking with your box cutter or silicone spatula and clean the gaps.
Step 2
Cut off the silicone cartridge and properly cut a tip of the nozzle at an angle.
Step 3
Affix the masking tape to avoid contamination of the surrounding wall by excessive sealants.
Step 4
Spread silicone to the gaps.
Step 5
Finish off the silicone caulking using the spatula to ensure the sealant is evenly and aesthetically filled into gaps.
Step 6
Remove the masking tap and check if there are silicone residues to ensure the surroundings are clean.
What should you pay attention to during the application?
You should clean the surface for the sealant to apply to. If there is water, dust, stain on the surface, its adhesion to materials will be affected and the bonding fails. Therefore, you should wash gaps using appropriate solvents (such as alochol) or detergents and wait until they are dried before applicaiton.
During the application, cut the tip of the nozzle to a proper size. It is better to have a nozzle that can reach half the depth of the gap. Slowly apply the sealant so that it completely fill the gap without any space left.
During the application, the ambient temperature should between 5-40℃ with a RH of 40%-80%. It is inappropriate to apply silicone in a drier or more humid weather. If the temperature of the surface under the direct sunlight exceeds 50℃, it is inappropriate to apply it.
After silicone is applied and not cured, it should not be rained or withstand load and movement.
During the application, wipe the sealant off from your hand using newspaper or a rag. The silicone is not corrosive so you can have a peace of mind.
The unopened silicone can be stored for 1 year under the room temperature (25 degrees). However, after it is opened, how it is stored determines how fast it is cured. Please store it properly and use up it asap.
