Bonding & sealing with Tec7: which product to use and when?

Always start with one question: “Can I solve this with Tec7?”

In most cases, the answer is simply: yes.

Only if your application has exceptional requirements in terms of speed, initial adhesion, anchoring or specialised sealing should you switch to one of the specialist products in the range.

The pioneer and the gold standard for general bonding and sealing work based on MS polymer.

• Specialisation: Unrivalled versatility. Replaces assembly adhesive, wood glue, PU adhesive, silicone sealant and acrylic sealant in a single cartridge. Bonds to wet surfaces, even underwater.

• Common applications: Fitting skirting boards, mirrors and window sills; sealing gutters, bath edges and joints; bonding wood, metal and stone.

• When to use it? In 95% of all construction, fitting and sealing jobs where a rock-solid, permanently elastic bond or joint is required.

The all-rounder with a distinctive, metallic finish.

• Specialisation: Pigmented with high-quality aluminium particles for a perfect stainless steel or aluminium look.

• Common applications: Sealing around stainless steel sinks, extractor hoods, aluminium profiles, banisters and splashbacks in industrial kitchens.

• When to use? For seamlessly bonding and sealing metals where the joint must blend in completely with the surrounding material.

The ultra-fast version of the classic Tec7.

• Specialisation: Offers all the benefits of the original Tec7, but reaches its functional strength considerably faster. Due to its speed, it is more of a pure adhesive than an all-rounder.

• Common applications: Bonding battens, skirting boards, kitchen units, bespoke cupboards, stair treads, panelling, etc.

• When to use it? When rapid curing is crucial for meeting deadlines, or in colder temperatures that significantly slow down the curing process of classic polymers.

PU adhesive foam for structural work.

• Specialisation: Bonds extremely quickly and is far cleaner and more efficient than traditional mortar or powder adhesive.

• Common applications: Bonding insulation boards (EPS, PIR, PUR) and plasterboards (Gyproc) to walls, and erecting internal walls using quick-build blocks or (aerated) concrete blocks (Ytong).

• When to use it? In structural and finishing work to bond large surfaces or blocks extremely quickly, dust-free and with minimal weight.

The liquid plug for structural anchors.

• Specialisation: A two-component chemical anchor that cures to form a solid, rigid bond that is stronger than the substrate itself. Styrene-free.

• Common applications: Anchoring threaded rods and reinforcing steel in concrete, brick or hollow walls. Fitting banisters, sections, etc.

• When to use? For heavy-duty, high-load and non-flexible anchoring in both solid and hollow building materials where a conventional plug would fail.

The ultimate instant adhesive (cyanoacrylate).

• Specialisation: Offers microscopic precision and sets in seconds. When used with the specific primer, it even bonds to the notoriously ‘unbondable’ plastics such as PP (polypropylene) and PE (polyethylene).

• Common applications: Repairing small items of jewellery, rubber O-rings, toys, electrical components and automotive plastics.

• When to use it? For small, precise repairs where a seamless, immediate bond is required.

The flexible, heavy-duty polymer sealant.

• Specialisation: Can accommodate significant movement and thermal expansion in buildings, and – unlike silicone – is perfectly paintable.

• Common applications: Facade joints, expansion joints in masonry, sealing around windows and doors (PVC, aluminium, timber).

• When to use it? For expansion joints (indoor and outdoor) subject to the heaviest loads, which need to be able to move without cracking, where the option to paint over the sealant at a later date may be required.

The silicone adhesive sealant for natural stone and swimming pools.

• Specialisation: 100% safe for natural stone (causes no edge staining or ‘bleeding’) and extremely resistant to chlorine and salt water.

• Common applications: Bonding and grouting marble, bluestone or granite, liners, mosaic tiles in swimming pools, pond edges and heavily trafficked outdoor flooring.

• When to use? For projects involving high-quality natural stone or applications in and around swimming pools and ponds where standard polymer or silicone adhesives fall short.
