Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Notes on component bonding with adhesive tape
Unless specified otherwise in vehicle-specific or component-specific instructions, the following notes apply.
Follow repair notes for bonded gaskets for rubber seals.
- General notes
- Bonding at room and object temperature of >+18°C.
- Newly painted parts may only be bonded after a drying time of at least 24 hours.
- Optimal bonding/attachment to the background surface is achieved after approx. 48 hours. Components must not be exposed to mechanical strain beforehand (car wash, strength test, etc.).
- Do not touch bonding area.
- It is not the length of time that pressure is applied but rather the force of pressure applied that is crucial.
- Detaching the adhesive tape after pressing destroys the adhesive layer.
- Auxiliary materials and tools
- Cleaning agent R1 or cleaning agent R2
- Sika Activator 205
- Fluff-free cleaning cloths
- Pressure roller
- Preparations
- Remove all adhesive residue or clean new part thoroughly
- Clean the areas to be bonded immediately before bonding to remove silicone and grease residues.
- Treat bonding on glass or painted surfaces with Sika Activator-205.
NOTE: Apply Sika Activator-205 extremely thinly. It must not be coated beyond the bonding surface.
Note air drying time ≥1 minute. - Bonding
- 4.1 Components without preassembled adhesive tape
- Detach liner* from adhesive tape
- Position adhesive tape on component and stick on
- Press down adhesive tape over entire adhesive area
- Continue with Point 4.2
* Liner is the protective film on the adhesive tape.
- 4.2 Components with pre-fitted adhesive tape
- Detach liner* from adhesive side (if adhesive area is large, do not detach liner completely)
- Align component in correct position on vehicle
- Press down component over entire adhesive area
Minimum contact pressure ≥ 15 N/cm2 (firm thumb pressure reaches approx. 35 N/cm2 .)
* Liner is the protective film on the adhesive tape.
- 4.1 Components without preassembled adhesive tape

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
