## Description

Sika Mounting Adhesive - Sikaflex-554 Black - Ideal for Large Components and High Dynamic Load - Ageing and Weather Resistant - 300 ml : desertcart.co.uk: DIY & Tools

Review: Used for mounting Motorhome solar panels. - I used this to mount solar panels to my motorhome roof. Great stuff and extremely secure bond using aluminium angle 3mm thick 50mm x 50mm bolted to the solar panel. No bolts used to attach to the roof just the adhesive. The panels were fitted 8 months ago and I regularly check the panels to ensure they're still secure - so far so good!
Review: Very sticky - Very effective, I used it to stick a solar panel onto my campervan roof
