Grouting joints at low temperatures:
Speed up silicone processing: Immersion heaters with automatic switch-off (e.g. item no.
10294, item no.
10295) heat cartridges directly on the construction site. This means that silicones can be optimally processed even in cold conditions. Heating makes the material softer and more evenly dispensable, which makes it much easier to apply to the joint. Particularly in the cold season, the constant temperature ensures that the silicone retains its adhesion and dimensional stability. This saves time, improves the joint appearance and ensures a lasting professional result.
Grouting silicone joints made easy
Grouting joints with silicone syringes & squeegees
Our silicone squeegees (e.g. item no. 10583, item no. 10625 - item no. 10629) and universal joint fillers (item no. 10577, item no. 10578, item no. 10554) enable clean, even results - without masking, in accordance with VOB. Thanks to their different edge shapes, they adapt perfectly to every joint and facilitate professional smoothing of the sealant. The tools sit comfortably in the hand, are easy to clean and are ideal for daily use on the construction site. This allows you to achieve a precise joint pattern that meets the highest technical and visual requirements in the shortest possible time.
Grouting difficult areas effortlessly - with the Fugenfux
The Fugenfux (Classic, Small or Multitool 5-in-1) with its ergonomic handle and magic tip ensures perfect silicone joints, even in hard-to-reach corners. (art. no.
12593) Thanks to the sophisticated shape, joints can be smoothed effortlessly without damaging the neighbouring substrate. The multi-tool combines several functions in one handy device and is therefore ideal for flexible use on the construction site or in the DIY sector. Whether you are repointing or repairing - with the Fugenfux, you can achieve precise, clean results for every joint.

Grouting joints with a perfect finish:
Joint smoothing, cleaning & pre-treatment Smoothing agent:
For a clean, professional finish when grouting joints, we recommend the universal smoothing agent (item no.
11215). It is suitable for all common sealants such as silicone, acrylic and even for sensitive materials such as natural stone. The matching spray solution in the practical spray bottle (item no.
10587) ensures particularly easy and even application - ideal for flexible use on the construction site or in interior work.
Silicone remover and cleaning wipes are ideal for optimum preparation before re-grouting. They reliably remove residues and create a clean basis for new sealing joints. The SiliSaver 2-in-1 (art. no.
11930) - an innovative attachment for precise, clean work - ensures particularly efficient cartridge processing without material loss.
Grouting old joints after thorough cleaning
Whether cement, dirt or mould: With joint cleaners (e.g. item no.
16109 - item no.
16113) and carbide joint scrapers (item no.
10915), you can optimally prepare joints for reworking. Stubborn residues can be thoroughly removed so that the new sealant can adhere reliably. A clean, residue-free joint is the basis for a durable and visually appealing result. The joint protection pen (art. no.
16104) then protects against mould growth and significantly extends the service life of the freshly renovated joint. This ensures permanently hygienic and well-maintained surfaces, especially in wet areas such as bathrooms and kitchens.
FAQ: Frequently Asked Questions About Sealants, Joints & Professional Fugen Tools
Which nozzles are suitable for hard-to-reach areas?
The long special nozzle, the 45° angled adapter and the 360° rotating joint nozzle are ideal for sealing in narrow or difficult-to-access areas.
For tight or hard-to-reach spots, specially shaped sealant nozzles are essential to apply silicone or acrylic precisely. The long special nozzle, the 45° angle adapter and the 360° rotating joint nozzle allow controlled application even in corners or behind fittings. This ensures a clean and even joint finish with minimal material waste and maximum accuracy — ideal for professional sealing in renovation and new construction projects.
Why should PE backer rods be used?
PE backer rods improve joint geometry, save sealant material and increase the durability of the joint.
PE backer rods ensure the correct joint depth and prevent the sealant from bonding on three sides. This increases the joint’s flexibility and reduces the risk of cracks. At the same time, backer rods significantly reduce sealant consumption, making the joint more durable, elastic and professionally shaped, especially in movement and connection joints.
How does the SiliSaver work?
The SiliSaver ensures accurate dispensing without dripping, making silicone application clean and controlled.
The SiliSaver is an innovative attachment for silicone cartridges that enables precise and controlled sealant dispensing. It prevents dripping and material waste, ensuring the sealant is applied exactly where needed. This leads to clean transitions, less cleanup work and a professional joint appearance, suitable for DIY users and professionals alike.
How do I smooth silicone joints without masking tape?
Use the universal smoothing agent together with silicone smoothing tools (e.g., joint shapers or silicone scrapers) to achieve a perfect result without taping.
The combination of universal smoothing agent and professional joint shaping tools allows you to smooth silicone joints quickly and evenly without masking tape. The smoothing agent prevents silicone from sticking to fingers or tools and creates a clean, smooth joint surface, ideal even on sensitive materials such as natural stone, with no stains or residue.
What should be considered when working with natural stone?
The universal smoothing agent is suitable for natural stone, but should be diluted and tested first.
When sealing natural stone surfaces, it is important to prevent discoloration or staining. The universal smoothing agent is suitable, but should be used in a diluted form and tested on an inconspicuous area first. This ensures a clean, stable and visually consistent joint on natural stone.
Are there special tools for epoxy resin joints?
Yes. Warm the cartridge before use and use hard-edged spatulas or profile shaping tools for precise finishing.
For processing epoxy joints, warming the cartridge makes the material easier to apply. Rigid spatulas and profile shaping tools allow controlled smoothing of the joint surface. This ensures a clean, professional finish, even for demanding epoxy applications.
How can joint sealant be applied efficiently and evenly?
Use a professional joint gun or compact cartridge press to apply sealant evenly with minimal effort.
A professional sealant gun or compact cartridge press ensures controlled and uniform dispensing of silicone or acrylic. With ergonomic handling and strong pressure transmission, the tool reduces fatigue and allows long, precise sealing sessions with consistent joint quality.
How do I reliably remove old silicone residues?
Use silicone remover and cleaning wipes for thoroughly cleaned surfaces that allow new sealant to bond properly.
Silicone remover loosens old sealant, while cleaning wipes remove remaining residues, dust and grease. Only a clean and dry surface ensures optimal adhesion of the new joint compound. This creates a durable and visually clean new joint.
Which tool is recommended for joint cleaning during renovation?
The master joint cleaner with diamond blades or a carbide joint scraper works best for removing stubborn old joint material.
The master joint cleaner with diamond-coated blades or a carbide joint scraper enables thorough removal of old sealant, grout and mold. These tools allow precise cleaning down to the smallest corners, which is especially important in renovation and refurbishment.
How do I prevent mold from returning after cleaning?
Apply the joint protection pen to create an antibacterial, moisture-resistant layer.
The joint protection pen creates an antibacterial barrier on the joint surface, significantly slowing down mold growth in humid environments such as bathrooms and kitchens. This keeps joints hygienically clean and visually attractive for longer with minimal maintenance effort.
