The Best Ways to Prepare a Shower Screen for Siliconing

Applying silicone around a shower screen might seem simple, but proper preparation ensures a strong, watertight seal that will last for years. Here’s a step-by-step guide on preparing your shower screen for siliconing, with tips to achieve a clean, professional finish.

1. Start with a Clean Surface

Ensuring that both the shower screen and surrounding surfaces are clean is essential. Any dust, soap scum, or grease left on the surfaces can prevent the silicone from adhering properly.

• Use a Glass Cleaner: For glass surfaces, use a quality glass cleaner or a mixture of vinegar and water to remove dirt and grime. I also use Xpro Super Solver that you can find here: http://www.sealantwholesale.com
• Degrease with Isopropyl Alcohol: For metal or tile surfaces, wipe down the areas to be siliconed with isopropyl alcohol. This helps to eliminate any oily residues that could interfere with the silicone’s bonding.

2. Remove Old Silicone (If Replacing Existing Sealant)

If you’re reapplying silicone to an existing screen, start by removing any old silicone. Leftover bits can interfere with a smooth, watertight application.

• Use a Utility Knife or Razor Blade: Carefully cut away old silicone using a utility knife. Be cautious not to scratch glass or metal surfaces.
• Apply a Silicone Remover: For stubborn residue, apply a silicone remover and let it sit for the recommended time before scraping it away. Rinse the area thoroughly afterward to remove any traces of the remover. Again I use Xpro Super Solver that you can find here: http://www.sealantwholesale.com

3. Ensure the Area is Completely Dry

Moisture can prevent silicone from curing properly, so ensure that all surfaces are thoroughly dry before proceeding.

• Use a Hair Dryer: If any areas are damp, use a hair dryer to remove residual moisture. Pay close attention to the edges and corners where water tends to accumulate.
• Allow Extra Drying Time: Even after visually inspecting, give the surfaces time to air dry completely. Patience at this stage ensures the silicone bonds tightly.

4. Apply Painter’s Tape for a Professional Finish

To achieve a neat, straight line, apply painter’s tape along the edges where you plan to apply the silicone. This is especially useful around corners and edges where precision is key.

• Position the Tape Evenly: Apply strips of tape on either side of the joint, leaving a small gap where you want the silicone to go.
• Check the Alignment: Double-check the alignment of your tape to ensure even spacing. The tape will help guide your silicone line and make it easy to remove excess afterward.

5. Choose the Right Silicone for the Job

Selecting the appropriate silicone is essential for a lasting seal. For shower screens, use a high-quality, mold-resistant silicone specifically designed for bathrooms.

I always use Xpro’s 365 sealant as it doesn’t mould over time and smoothes off just lovely – you can find it here: http://www.sealantwholesale.com

• Look for “Sanitary” or “Mold-Resistant” Labels: Shower areas are prone to mold growth, so ensure your silicone is resistant to mold and mildew.
• Opt for a Clear or Matching Color: Choose clear silicone for a minimal look, or a color that matches your bathroom fixtures for a seamless finish.

6. Prepare the Silicone Applicator for Smooth Application

Getting a smooth, consistent application of silicone relies on both technique and the condition of your silicone applicator.

• Cut the Nozzle at an Angle: Use scissors to cut the applicator nozzle at a 45-degree angle. This angled cut helps control the silicone flow for a smooth, clean line.
• Practice on Scrap Materials: If you’re new to siliconing, practice on a scrap piece of wood or cardboard to get a feel for the right pressure and angle.
