Please note: Porous surfaces should be primed first. Do not use on surfaces where water can penetrate through porous materials to the bond interface without first carrying out remedial work. Polished decorative stone such as granite, etc. may absorb silicone oil from the sealant and undergo a change in surface gloss. The safety backing on some mirrors is not suitable for adhesive fixing with silicone. If using mirrors with a safety backing always carry out an adhesion test.

Deliveries are made on the basis the customer can accept the goods, or willingness to off load the goods, or having means of mechanical offload, this also applies to heavier items such as pallets etc. All deliveries are made ‘kerbside’ and often it can be at the discretion of the driver. A large majority of deliveries would be made on a large rigid tail-lift vehicle and off loaded via a pallet truck and only on to flat surfaces such as tarmac, concrete and pavers.
