How to: Seal baths, showers & basins
With a large selection of sealants available to seal the gap around baths, showers, basins and other bathroom items, choosing the right one is incredibly important. Once you've chosen your sealant, then comes the even harder part...applying it professionally.
Luckily that's why we've created this guide.
Choosing your sealant
Each sealant will have it's own strengths so it's important to use the right one. For this guide, however, we're going to be covering the efficient and versatile Everbuild Showerproof Bathroom Silicone.
Able to adhere to most smooth materials, the sealant contains a powerful anti-fungal compound and forms a flexible, fast-curing rubber seal.
Before you start, these a few simple tasks that will save you valuable time as well as start you on the path to a professional finish.
First up, ensure that the surfaces where the sealant will be applied are clean and grease-free.
Next, you'll want to fill any large gaps to prevent wasting the sealant. To do this, fold some sheets of newspaper lengthways repeatedly until you have a long bulky strip. Pack this carefully into the gap, pushing it about ½ cm below the surface.
If the item to be sealed will be prone to movement e.g. a plastic bath, half-fill the item with water to account for this.
To ensure a smooth-edged finish, you'll next want to mask off your application area (there are plenty of great masking tapes to choose from for your application in our collection here). Leave a gap of around ½ cm either side of the area and smooth down the tape to guarantee a good contact.
Finally, we'd recommend laying some newspaper on the floor nearby to lay your tools. Sealant can be very difficult to remove so this will help keep things clean and tidy.
Applying the sealant
Trim the nozzle of Everbuild's Showerproof Bathroom Silicone sealant using a craft knife at a 45-degree angle and fit into a standard sealant gun.
Hold the sealant gun with the nozzle touching the edges of the tape at a 45-degree angle. Squeezing the trigger evenly, feed a bead of the sealant into the gap using your thumb to push the pressure release lever when at the end.
Next, you will want to check back to ensure there are no gaps or areas that require more sealant. If there are, fill these in accordingly.
Once all areas have sealant in place, put down the gun and pick up an old rag. Form a point with your finger inside the rag and dampen it in some water. Starting at one end, draw it along the sealant with the same motion you would use as if you were smoothing down tape. If you can do this is one smooth movement it will create the most even effect, although if you end up with too much excess on your finger you will need to wipe this away to prevent it spilling onto the surrounding area. Be sure to dampen your finger and rag at each restart beginning a couple of inches before where you stopped. The end result should resemble a concave sitting between the edges of the tape.
Finishing the job
Before the sealant dries, you will need to remove the tape. Starting with the tape on the wall tiles, peel off the tape out at an angle of around 45 degrees taking care not to drop it back onto the sealant. Repeat this for the tape on the item and the allow the sealant to dry. If you'd previously half-filled the item to allow for potential movement, drain this away once the sealant is completely dry.
And there you have it, a professional looking sealant job using the brilliant Everbuild Showerproof Bathroom Silicone.
