Installation Steps

Before installing the slidemount, please find the description for each component in your package here:

Side Slidemount C4 Description

Please find the video installation guide after the VHB preparation

(Optional) Prepare your VHB: (ONLY if you redo the VHB)

  1. All slidemount already come with pre-applied VHB. If you would like to redo the VHB, then please follow the steps to prep it. Please make sure you apply the adhesion promoter before applying the VHB.

  2. Warning: Apply the VHB tape to the slidemount, first before you stick it on the windshield. And apply the VHB in warm temp. If you are reapplying the VHB tape, Clean the surface with isopropyl alcohol and ensure that no residue remains.

  3. (Important) The ideal application temperature for VHB is above 70°F or 21°C. The minimum application temperature is 50°F and 10°C. If the temperature is lower than the minimum required, you can try to heat up the application area before and after attaching the magmount. Use common sense when heating the application area and avoid overheating or leaving it unattended. The VHB also need the above minimum required temperature for curing. Please leave it at least 24 hours or 1.5x the curing time recommended by 3M. Below is a snippet of recommended bond time from the 3M datasheet.

  5. Take the Windshield Side Mount.

  6. Wipe the back of the Windshield Side Mount with the IPA wipe.

  7. Apply adhesion promoter to every surface (except on glass) that the VHB is going to stick to and let it dry. (If you have windshield tint, please try it on a small area first, some tint does not do well with the adhesion promoter)

  8. Apply VHB tape to the Windshield Side Mount.

  9. Clamp or use weight on the complete slidemount for at least 5 hours so VHB makes perfect contact to the surface. Every VHB-connected surface needs to be clamped. (The complete slidemount here means slidemount with angle wedges and VHB or slidemount with mount adapter sticked together. )
