SPIKES INSTALLATION
AviClips
Straight gutters and some profiled gutters take std Gutter Clip, roll topped gutters need Lipped Gutter Clip.

Preparation
- Use scraper/wire brush to remove all dirt, droppings, flaking paint, rust, vegetation
- Use Surface Cleaner to remove grease
- Use Primer 150 on porous surfaces e.g. sandstone
- Use Surface Activator for extra bond strength e.g. when sticking window clips onto PVC frames
Gluing
Apply at least 5mm bead of adhesive into the glue guide, more if the surface is very uneven.
Positioning
Press firmly into place, overhanging the edge of the ledge by 5mm. If fitting multiple rows, allow max 65mm between rows medium pressure and 50mm heavy pressure.
Variations
Pipes - use cable ties to prevent spikes falling off before glue cures.
Curved Surfaces - split the strips across the snap lines and stick them on as separate sections. Whole strips might spring up.
Edge Protection - spikes can be installed just at the edge of a ledge if the perceived problem is only droppings on the face of the building
