Our builders are cladding up an area under a side pergola using cement sheets. They are installed, and they are about to cover the joints of the sheets with thin wooden battens. I would prefer a smooth wall look (without the battens) and wondering if there is a product that could be used to seamlessly fill the joins. The sheets are not recessed for seamless joins, but entirely flat. The joins are generally tight.
The wall is in full sun in the afternoons.
Hoping for good advice!
Cheers,
Geoff
