One part non staining silicone sealant for natural stone to ISO11600 F/G20LM.
Suitable for joints up against natural stone (it is strongly recommended that the sealant is tested against the stone before application).
Resistant to most alkalis and dilute acids; organic solvents may cause the sealant to swell and loose adhesion, but do not directly dissolve the material. Should not cause staining of stone, concrete or masonry.
Burns, but will not readily ignite, so does not constitute a fire hazard.
Very good UV resistance.
Correctly applied, the sealant should not require maintenance, and has an anticipated life in excess of 25 years.
Health and safety:
The product is labelled as irritant; its use should be recorded in the project Health and Safety Plan.
+5°C to +50°C.
7–14 days depending on joint configuration and atmospheric conditions.
A combined joint filler/ bond breaker, such as closed cell foam polyethylene rod, should always be used to ensure that the sealant adheres only to the joint faces and not to the back. Bond breaker tape should be used where the joint has been packed out with fibre-board.
Although Arbosil XL 1099 has exceptional adhesion and, in most cases, will not require use of a primer, some friable or brittle stone surfaces will need priming with Arbo Primer 2650.
Primers are available to suit other substrates – refer to technical literature for details.
A primer is not required for polyester powder coated aluminium or steel, mill finished aluminium or anodized aluminium or glass.
