GE Silicone II failure
I just checked the seal between polycarbonate and wood on a frame, and the GE Silicone II I put on there is peeling off and not keeping out water. Anyone else have this problem with this product? Is there something else you recommend?
Thanks, Mike |

Is it continuously wet? Is this an interior or exterior application? Is it both? Did you get your surfaces prepped perfectly clean before sealing? "My caulk isn't sticking" is too vague. Robert |

Silicone doesn't stick to policarbonate very well.Particularly if it is not PERFECTLY clean. |

Silicone doesn't stick to policarbonate very well.Particularly if it is not PERFECTLY clean. It bubbled off the polycarbonate. I guess that's the part I'm not understanding. Isn't silicone supposed to stick well to polycarbonate? They were clean. I'd just pulled the plastic off when I installed last fall. Thanks. Q. What type of sealant should be used on sheets? A. Only use a €ś100% silicone€ť sealant on polycarbonate sheets. Silicone sealants do not degrade in sunlight. They resist mold and mildew and remain flexible, allowing for building movement. Do not use roofing caulk. Consequences of using incompatible sealant are inadequate adhesion, too rigid of a bond, and/or the product contains chemicals that may discolor or damage the polycarbonate sheet. Check the product information on the sealant label BEFORE using to ensure compatibility. http://www.ameriluxinternational.com/faq.php |

Isn't silicone supposed to stick well to polycarbonate? They were clean. I'd just pulled the plastic off when I installed last fall. Thanks. Q. What type of sealant should be used on sheets? A. Only use a “100% silicone” sealant on polycarbonate sheets. Silicone sealants do not degrade in sunlight. They resist mold and mildew and remain flexible, allowing for building movement. Do not use roofing caulk. Consequences of using incompatible sealant are inadequate adhesion, too rigid of a bond, and/or the product contains chemicals that may discolor or damage the polycarbonate sheet. Check the product information on the sealant label BEFORE using to ensure compatibility. http://www.ameriluxinternational.com/faq.php A friend had a cold windy ride home from somewhere between Thunder Bay and Kitchener Ontario when the replacement window he installed on his Pelican aircraft blew out on route because he cheaped out and siliconed a piece of polycarbonate in place instead of using the recommended urethane adhesive. |
