Bird Spikes Adhesive for Dry Weather
AVISIL Neutral Silicone.
Clear, high quality, neutral-curing silicone adhesive. It offers excellent adhesion on most building materials including brick, concrete, stone, plaster, paint, stainless and galvanised steel, lead, copper, brass, aluminium, PVC, PPC, ceramic tiles and glass. This professional product cannot be found in DIY shops. It has a wide temperature and UV resistance. 1 tube of 310ml can install over 10 metres of Bird Spikes (use with a caulking gun).
Note: Please do not use standard silicones (e.g. used in bathrooms) with bird spikes. They contain solvents that leach out of the silicone bead, causing shrinkage which degrades the joint after a few years.
