Kit removal and application is a job that many people underestimate. Yet it is essential for a tight, watertight and professional result. Whether you want to replace sealant in the bathroom, kitchen or around windows: with the right products and method, you will get joints that look like new. In this guide, you will learn step by step how to remove old sealant, clean surfaces and apply new sealant like a true professional.
Why sealant removal and application is important
Old sealant is often affected by moisture, soap residue and dirt. Even if the joint still looks reasonable, new sealant adheres poorly to the old layer. As a result, air bubbles or cracks can form and moisture gets between the joints more quickly. Mould can also continue to adhere under the new layer.
By first removing all the old sealant, you lay the foundation for a durable, waterproof finish that will last for years. It's a small effort that makes a big difference in the end result.

- Removes sealant residues

How to remove sealant residue?
After cutting out the old sealant, residue is often left behind. These may seem small, but they cause poor adhesion of the new sealant. You can use a knife or putty knife to remove most of it, but for a really smooth surface use Super Silicone Remover.
This is how to remove sealant residue step by step:
Cut away as much of the old sealant as possible with a sharp knife.
Apply Super Silicone Remover to the remaining sealant.
Let the product soak in for a while until the sealant softens.
Remove the residue with a plastic scraper or sponge.
Rinse well with clean water and dry the surface thoroughly.

Benefits of the Super Silicone Remover
Works on silicone, acrylic, butylene and universal sealants.
Suitable for removing glue residues and adhesive layers.
Ensures a perfectly clean surface to which new sealant adheres optimally.
Applicable on both indoor and outdoor surfaces.
Extra tip: degrease for perfect adhesion
Even after removing all sealant residue, grease and dirt can remain. Grease hinders the adhesion of new sealant and causes joints to loosen later.
Therefore, use Super Pro All-purpose Cleaner & Degreaser. This Ecolabel product is biodegradable, powerful against grease and safe for almost all surfaces. Apply with a cloth or sponge, allow to work in briefly and rinse well. Then dry the substrate completely - only then is the substrate ready for resealing.

Kit removal in the bathroom
In the bathroom, sealant gets a hard time from moisture, heat and cleaning agents. As a result, mould spots, loose edges and discolouration develop more quickly.
Remove old bathroom sealant:
Carefully cut off the old sealant with a sharp knife or plastic putty knife. Work accurately along the tile edges, bath or shower tray. Then use Super Silicone Remover to soak off any residue left behind.
Let the product soak in briefly and remove the soft sealant with a sponge or scraper. Then rinse everything well with water and dry the joints carefully.
Prevent recurring mould:
Mould occurs when moisture remains in small cracks. After removing old sealant, always clean with Super Pro All Purpose Cleaner & Degreaser to remove soap and lime residue. Then let the joints dry completely, ideally 6 to 12 hours before applying new sealant.
Ventilate well or use a fan to speed up the drying process. Only a dry, clean surface will prevent new sealant from loosening or re-moulding.
Remove sealant from windows and glass - safely without scratching
With windows, glass and frames, caution is essential when removing and applying. Old silicone sealant or acrylic sealant can be stubborn here, but glass is prone to scratching.
Always use plastic tools and not metal scrapers when doing this job. Cut off the old sealant with a sharp knife and then apply Super Silicone Remover to the remaining edges. Let the product soak in for a few minutes and remove the soft residue with a plastic scraper or cloth.
Troubled by glue or tape residue on glass?
Then use The Super Sticker & Ink Remover. This product removes glue residues, adhesive layers and old sticker residues without leaving streaks or scratches. Ideal when renovating window frames or resealing window edges.
When finished, rinse the glass with water and dry with a soft cloth for a streak-free result.
Applying new sealant - this is how to get a tight result
After cleaning and degreasing, you can apply new sealant. Choose a suitable sealant for your job - for example, mould-resistant sanitary sealant in the bathroom or universal sealant for window frames and kitchens.
For a really tight end result, use when finishing the Super Finisher 500ml. This ready-to-use spray prevents the sealant from sticking to your tools and allows you to smooth the joint perfectly. Even if you are not an experienced handyman, with the Finisher you get professional, even joints without smudges or unevenness.
Step-by-step plan for applying new sealant:
Stick painter's tape along the joint for clean lines.
Cut the nozzle of the sealant tube at an angle, slightly narrower than the joint width.
Place the tube in the sealant gun and pull the trigger evenly across the joint.
Fill the joint in one smooth motion, without interruptions.
Spray Super Finisher 500ml directly onto the fresh sealant and adjacent surfaces.
Smooth the joint with a jointing wood, PVC pipe or putty knife. Lightly moisten the tool for an extra tight result.
Then let the sealant cure completely - usually this takes 24 hours. During this time, avoid contact with water or cleaning agents.
