Adhesive-Base Bird Spikes: Frequently Asked Questions

Short, direct answers to the questions buyers actually ask before ordering adhesive-base bird spikess — collected from the specification, pricing and inspection questions that come up in real enquiries. Where an answer depends on your site conditions, the condition is stated rather than hidden.

Product questions

Which adhesive should I use?

Neutral-cure structural silicone, never acetoxy — the acetic acid attacks the PC base and some stone. Ask whether the factory quotes a kit with cartridges matched to the strip count.

Do I need primer?

On dense concrete and glazed surfaces, no. On porous limestone, sandstone and weathered brick, a silicone primer doubles the bond and costs pennies per metre.

Ordering questions

What is the typical minimum order and lead time for adhesive-base bird spikes?

The usual minimum is 1,000 m, and repeat specifications run 10–20 days. First orders with new tooling or custom colours sit at the long end of that range; stock configurations sit at the short end.

How should adhesive-base bird spikes be packed for export?

50 strips per box; optional kits with one 300 ml silicone cartridge per 12 strips. If your shipment routes through humid climates or long storage, say so in the RFQ — packing upgrades are cheap at the factory and expensive as a claim.

Which quality tests should accompany a adhesive-base bird spikes shipment?

At minimum: shear retention ≥ 80 N per 500 mm strip on primered concrete; UV ageing 2000 h; pin pull-off ≥ 50 N; channel depth audit (≥ 6 mm). Type-test certificates qualify the design; ask additionally for per-batch routine records, which are what tell you what actually shipped.

What goes wrong in the field with cheap adhesive-base bird spikes?

The recurring failure modes are: strips lifting at the ends; adhesive failure on dusted stone; channel too shallow. None of them are visible at goods-in, which is why the specification and the batch records matter more than the sample.

A note on honest specifications

Every answer above comes from the same product data behind the specification guide and the inspection checklist for this product. If your question is not answered here, put it in the quotation request — a supplier who answers an awkward question narrowly and honestly is worth more than one who answers everything with “yes, no problem”.

When this is the wrong product

Adhesive-base bird spikess are the right tool when listed and heritage façades where drilling is forbidden; membrane and metal roofs where penetrations void the warranty. If your situation is closer to “fast installations over long ledges” — or you are not sure — read the category guide first and check whether a sibling product fits better before you price the wrong one.
