Silicone seals are required for your shower or tub shower to prevent leaks and other kinds of damage due to infiltrations. When applied correctly, it gives your bathroom a clean finish and the best part is that you can do it by yourself! Here are the steps you should follow to make sure that your shower is perfectly sealed using silicone.
Step 1: Apply masking tape
First, we recommend to lay-strips of masking tape on either side of every joint you wish to seal around the bath or shower (tape of 1″/25mm wide or more). The full length of all the joints should be covered. Every piece of tape should be kept about 3mm (1/8″) back from the joint to make sure that there is enough room to apply the silicone. Do not put the tape too close to the joint. The tape will help to keep the extra silicone off the floor, walls, and other surfaces.
Step 2: Apply a silicone seal precisely on all shower joints
Remove the tip of your silicone tube using a knife and place it carefully in your caulking gun. Screw on your nozzle and cut off the tip at a 45 degree angle. Proceed to run a line of silicone long every joints starting in a back corner and working forward. Do not press hard on the silicone tip in the corners. It’s easier to do vertical joints from top to bottom. The lower section of the vertical joint can be done from the bottom. Incline your silicone nozzle to make it easier to reach bottom joints of the bath or base. Silicone dries quickly, so finish a couple of lines (as explained in Step 3) before repeating the process for the joints. This will ensure a clean finish.
Step 3: Finish the line of silicone
Fill a glass with water and a generous dose of dishwashing soap, approximately 1 Tbsp. Dip one finger into the soap solution and run it smoothly along the bead of silicone to remove the excess and create an even line finish. Always have an old rag in your hand to remove the silicone from your finger before dipping it again in the soap solution. Make sure your finger is wet to ensure a better result. If you prefer not to use your finger, tools that replicate the finger are also available in the hardware stores. Begin to remove the masking tape once you’re satisfied with the look of the silicone. Don’t wait until the silicones dries. It is highly recommended that you pull the tape away from the join instead of towards it to make sure that you obtain a clean finish.
Step 4: Curing and external seal
Curing time of the silicone must be respected to ensure a proper seal & avoid leaking. Respect the silicone manufacturer’s recommendations about curing time, but for optimal results, wait a minimum of 24 hours. An external joint of silicone can be applied around the shower or tub shower joints once the drywall is applied to complete the install.
