* Not for use in conjunction with bitumen, or asphalt. Use WEATHERMATE SILICONE
* Do not use on lead or soft metals. Use LEAD MATE SILICONE.
* On highly porous surfaces such as new  concrete, priming is advised or use SILICONE 450.
* Not for use on substrates that may bleed oils, solvent  or plasticisers.
* Do not use in the vicinity of, or in conjunction with the edge sealant of double glazed units. Use SILICONE 450.
* Use on uPVC and plastic components: Due to the wide variety and quality of these materials, the user must always carry out an adhesion test prior to use. For optimum adhesion,  use SILICONE 600 or SILICONE 450. Thermal movement of PVC-u frames can be excessive. This product accommodates movement of +/- 35% of the joint width. For a higher movement factor use SILICONE 600 or SILICONE 450. When perimeter pointing to G.G.F standards, use only SILICONE 450 neutral cure.
* Overpainting is not possible, so on applications where overpainting is required, use  WEATHER MATE isoacrylic sealant (external only) or MIRROR MATE (internal or external use)
