How to seal SunLite8 Polycarbonate greenhouse?

[reidt]

Building a DIY small hot house with SunLite 8 Twinwall Polycarbonate & looking for the best silicone sealant to use.
Worked my way through all the silicone sealant products listed but nothing specific for polycarbonate.

Google search recommends Alseal Sealant AS-209 & Securbond Silicone.

Would appreciate any guidance on best silicone choice.

Cheers

Hi @reidt,

A warm welcome to the Bunnings Workshop community and thank you for your question.

You're going to want a neutral cure silicone that is designed for use outdoors. 

This Selleys 310g Translucent Roof And Gutter Silicone Sealant will be perfect for the job as it is designed for use in roofing projects.

It comes in a variety of colours, but the translucent one seems like the best option for you.

Let me know what you think.
