In this guide, we'll show you the right way to apply silicone to your new shower screen to ensure a watertight seal that lasts.
Whether you're a DIY pro or a beginner, our expert tips will help you achieve a flawless finish.
Say goodbye to leaks and hello to a stylish, functional shower space. Let's get started!
Before we get started with the step by step guide, let's take a quick look at the tools you'll need:
Sealant Gun:
A sealant gun, also known as a caulking gun, is an essential tool for applying silicone sealant. It allows for controlled and precise dispensing of the sealant.
Sanitary Silicone:
This is the specific type of silicone sealant designed for use in wet and humid environments, such as bathrooms. It provides a flexible waterproof seal and is resistant to mould and mildew.

Stanley Knife or Blade:
A sharp knife or blade is necessary for cutting the nozzle of the silicone tube to the desired size. This determines the thickness of the bead of sealant.
Silicone Smoothing Tool:
This tool is used to shape and smooth the sealant after it has been applied. It helps create a clean and professional finish.
Spray Bottle of Washing-up Liquid and Water:
This mixture acts as a lubricant for smoothing the silicone sealant, preventing it from sticking to the tool or smearing along any surfaces.
Kitchen Towel or Clean/Dry Cloth:
These are used for preparing the joints and for cleaning up any spills or smudges during the application process.
Bottle of Methylated Spirit:
Methylated spirit, also known as denatured alcohol, is used for cleaning and preparing the surfaces before applying the silicone sealant.
Having these tools ready and understanding their functions will greatly facilitate the silicone application process, leading to a more successful and professional-looking finish.
Before You Start Sealing Your Shower Screen
Once you have screwed the new shower screen frame in place, it's time to apply the silicone.
The assembly instructions that come with your new shower screen usually show you exactly where the silicone needs to be applied. However, if this is not shown on the instructions, don't panic, we are here to help.
Where Do You Put Silicone Sealant On A Shower Screen?
Apply silicone sealant around the OUTER edges (red arrows in above picture) of the shower screen frame where it meets the wall and base. This includes the vertical edges (down the wall) and the bottom edge (along base) of the frame (red arrows in above picture).
DO NOT apply silicone along the base of the frame, INSIDE the shower unit.
Shower screen frames are intelligently designed to allow moisture to escape from the bottom of the frame and run back into the tray or bath tub.
This design feature helps to prevent water build-up within the frame, which could potentially lead to mould or deterioration of the frame material over time and potential leaks.
I also like to to seal down the vertical edges of the frame inside the unit (yellow arrows in above picture) . This is an extra precaution to minimise the amount of moisture that actually gets down the back of the frame.
Areas NOT To Apply Silicone On A Shower Screen
1) Around Hinges & Other Moving Parts
2) Along the bottom of the frame inside the shower unit
3) Along where glass meets frame.
How To Silicone A Shower Screen
Now you know where and where not to apply the sealant on the shower screen. Let's look at how we do it.
Follow this step by step for a completely water tight, fully functioning shower screen.
1) Prepare The Area
Add a small amount of methylated spirit to a cloth or piece of kitchen roll, and give the joints you are sealing a wipe. Ensure the joint's are completely dirt, grit and dust free and completely dry before moving on to the next step.
Why use methylated spirit?
The methylated spirit is not only a great cleaning and degreasing solution. But the residue evaporates almost immediately. This will ensure the joints are completely dry before applying the new silicone.
2) Load The Silicone Gun
Load the silicone sealant cartridge into the gun and cut the nozzle at a 45-degree angle. The size of the opening will determine the thickness of the bead. Start with a small opening and enlarge it if needed.
3) Apply The Silicone Sealant
With the gun at a 45-degree angle, gently squeeze the trigger and move it steadily along the joint between the shower screen and the wall or base. Apply a continuous bead of sealant, ensuring full coverage. Use a consistent speed to maintain an even line.
4) Smooth The Sealant
After applying the sealant, spray the bead with the soapy water, this stops the sealant from smearing or sticking to stuff it shouldn't when tooling. Then use a silicone tool to smooth and shape the bead.
This ensures an even, professional-looking finish.
DO NOT lick your finger and smooth the sealant. The bacteria in your mouth can transfer to the sealant and cause premature mould growth. Also, it's disgusting!
5) Allow Sealant To Cure
Let the sealant dry and cure according to the manufacturer's instructions. This typically takes 24-48 hours, but it's best to check the specific product guidelines.
Do not use the shower until the sealant has fully cured. With the right materials and a bit of patience, applying silicone sealant to your shower screen is a manageable DIY project. By following these steps, you'll not only enhance the visual appeal of your bathroom but also ensure a watertight seal that stands the test of time.
Remember, practice makes perfect, so don't be discouraged if your first attempt isn't flawless. With each application, you'll refine your technique and achieve professional results. Enjoy your newly sealed shower!
