Best sealant for Hardie board
I had to replace some Hardie plank on my house and looked up what was recommended by the OEM for sealant and OSI Quad Max is what Hardie recommends.If you want a sealant that is not going to let go and last a long time - this is it.

Bought cause my contractor used it
Recently had some windows installed and this tuff kept its shape and shines months later. So I bought some to redo some others windows at another house that were done 5 years ago. Looking forward to great results with it long term.
