*by M***U on Reviewed in the United Kingdom on 13 July 2020*

I used this to affix to my OSB boards on my man cave I'm building.It protected the boards from the elements and it done a great job, none of the lashing rain we had got through.I know this is for roofs but it worked just as well on my outside walls before I put the battens and cladding on.It is made from very strong materials.A great price also.
